Wow, I didn't think it would be that close! I do use LED lights to boost light for my houseplants but to grow plants in my windowless basement I stick to grow lights, this makes me want to conduct an experiment of my own!
A 6400-6500Kelvin LED Tube is sufficient. Most plants benefit more from the blueish to cold white light spectrum in the early growth stages. Way cheaper and if you place your plants outside later on, it won't matter as they will get the boost from the sun. I started many plants like that from tomatoes to chili. Growth lamps will make a difference if the whole grow cycle of the plant will be under artificial lights as the warmer red spectrum are more beneficial for blooming and fruiting.
just get a socket splitter 1:7 and mix household cold white with warm wight from dollar tree, even cheaper and you get full spectrum without expense. I do it for interior lightening
@@fredrikhurlen8524 "I am using 4000k" Same here. I have a permanent setup to keep mother plants, take and keep clones and start seedlings etc. It runs on a variety of 4000k bulbs of different wattages (with and without diffusers) and sometimes a flat panel bathroom light depending on what's in there, what stage they're at and how close they are to running out of head height. 4000k seems to be the optimum for my purposes. I've tried them all. I've a drawer full of all the other colour temperatures if anyone wants them. 🙂 Top tip: Pry those diffusers off the bulbs. I manage to take them off so that I can clip them back on if I want. The increase in light output without the diffusers is substantial.
I've posted this a few times but it seems it's not that widely known: if you take off the plastic defuser you'll get stronger light from the LED bulb. The easiest and safest way to take off the diffuser is by squeezing it in a bench vice. They can removed by cutting them off but this can be tricky with less favourable results. The diffuser is basically a plastic half ball that's attached with glue so a little pressure in a vice makes it kind of "pop off". Farming LEDs don't have diffusers so it should be safe to take the defuser off.
mucking about with home lighting as grow lights is a waste of time and money. you really need a super bright light source for getting plants started, else they will not grow well. The amount of lumens in proper grow lights is insane, compared to house lighting globes. one of my one foot square led growlights is 150W, hanging comfortably a foot and half above seedling tray. i tried mucking about before with led shop lights etc., and they were a waste of money and time, producing dissapointing results. save that money, and buy proper growlight.
I'd have to agree that if starting with nothing it wouldn't make sense to 'invest' in the home lighting solution I showed. As you say, just not that effective for what you'd spend. My idea was more in terms of re-purposing existing things around your house: old lamps and bulbs, which might allow you to give seedlings a bit of a boost you'd otherwise not have. But yes, I'd like to showcase the difference that can be had with a proper lighting system in the future. Thanks for watching!

@PuraVidaPhotography Is not a true accurate comparison test because you are using two different lamps. Is your slight "more robust' plant grown with the grow bulb due to the bulb performance or the lamp that was used? One way to find out and make you comparison test experiment more accurate is to repeat your test but switch the light bulbs to the opposite lamps and ddocument your results. Maybe in the next test, the grow bulb will not be producing a more robust plant when switched to the other lamp and if so, then the results of this video post and my suggested comparison test #2 would perhaps be the performance of two different lamps? A better comparison test suggestion is to used exactly the same lamps preferably tested at the same time side by side. Any equipment used in a comparison test should be the same EXCEPT the variable which in this case would be the different light bulbs that your testing.
one thing I can say with these full spectrum lights : ur plants will die if you overuse the light. I was wondering why all my plants kept dying, I was falling asleep with their lights on some days. They need like idk 12 hours a day with these, with like maybe 16 max, anymore ur risking damage, and they need to sleep everyday with lights out.
I've tried CFL's, cool and warm. Incandescent, cool and warm. LED, cool, daylight and warmer. An LED actual grow light. I've even mixed color temperatures in the same fixture. They all work fine but the timing is critical. I usually start too early for my zone. Wish more people would grow gardens in my area. It's getting quite rare lately.
6400-6500k for all plants is best. but ya any grow light will work. I got some bright 6500k bulbs in fixtures. Sunlite 80728-SU LED A21 Super Bright Light Bulb 1600 Lumens, 15 Watt (100W Equivalent), Dimmable, Medium Base (E26), UL Listed, 1 Pack, 65K - Daylight and I also like those amazon ones with the small white square rectangles that have a vice clamp for windows sills and tables with two of them snaking out. Those long round colored tube ones stay away from. They fade over time or start blinking forcing you to lower the light intensity or they just die altogether. Those other ones I mentioned though last for years. 6 years for me 12 hours a day 4 sets from two different companies. relassy and bozily. every one of those colored tube lights I got from various manufacturers died in a year or two and they never got as bright from the start.
Thank you, I'm about to buy some lights for my house plants because I ran out of space under the windows. It's kind of relief to see it's not that significant. I didn't even know regular lightbulb is enough for them.
Old school, flourescent lights work great as well. My granny would keep her plants alive in the garage during the winter with just a flourescent light above them.
Guys don't let the term grow light deceive you there are normal house light with the same specifications and just as much efficiency as some of the really budget so called grow lights
This is a good point. Marketers like to complicate things. I have been think about revisiting this looking at more of the 'regular' bulbs. But in the mean time the point stands: any old light bulb is probably good enough for starting seeds!
The lights were about 2 feet away from each other. I felt there was minimal, if any chance of light spillover affecting the other group in this case as typically you want your grow lights as close as possible, and there was only minimal, indirect light coming to the opposite group. Reason I kept them relatively close was so that they would get the same amount of ambient light and not skew results that way.
The one flaw to this experiment is that they are both in the same roon, close enough to each other, that the indirect light from both light sources can influence the growth of all the plants. For more accurate results... you should grow the plants in separate rooms, each with a different light source. We did this same experiment in my botany class. The plants were seperated into 2 groups, in seperate rooms... 1 room with grow lights, & the other room lit with 6000k LED lights. After 8 weeks... both groups of plants were equally strong & healthy, under both lighing conditions... but the plants grown under the grow lights were on average 40% larger. The plants under the grow lights produced more sugars, because a much greater percentage of the light output from the grow lights is in the Blue & Red spectrums, than what the normal white LEDs produced.
You're correct, and that is something I hope to rectify next time around. That's really interesting to hear about the results you found in your class too!
GE makes LED light bulbs in different color spectrums ranging from warm to cool. I need supplemental light for my orchids and other flowering plants and combined bulbs with blue and red ranges in floor lamps and it’s working quite well. They’re not marketed as grow lights but pretty much accomplish the same thing, IMO. I have an LED lamp but it is too bright and the light is so blue that it gave me a headache. My plants are responding well. Although my setup was not expensive, it works for me. The output is around 1500 FC which is pretty bright. I thought I might experiment with summer annual seed starting as well.
I've been growing cannabis indoors for a little over 30 years. When LEDs came out of coarse I purchased a few. To try and cut my electricity cost. So over the years I have spent thousands on numerous supposedly high end LEDs. Well about 12 years ago I decided to give aeroponics a try. So I started designing my own aero systems. As I was doing this I could see it would be more efficient to grow in what is called the Sea Of Green ( SOG ). Which means you grow your plants very close together. For example, in my aero systems my plants are a little less then 2" apart. My aero systems measure 2'9"x 3' so lets say 9 s/ft. In that 9 s/ft I have 46 plants. You might be saying " well what the hell good is that". First off I am using every single bit of light that the fixture is producing. And next, when you grow in the SOG, you are concentrating on the main top of the plant, which is always the most potent and produces the biggest bud. So in my 9 s/ft area I'm getting 46 main tops compared to the normal of growing 1 plant in that same area and getting only one main top. Now I'm sure hear, there is going to be people making comments that you can train your plants to get a even canopy. Yes you can. And it's a total waste of time. And adds a tremendous cost on to your final product. No matter how you train the plant, you are still only going to get one main top. So now finally I'm going to get to the point of this long story. So once I started growing with my aero Systems. Right away I was seeing a problem. And it was very strange. All the plants all the way around the outside edge of my aero Systems. Like 3 rows of plants all the way around. Were suffering. They weren't growing good. They were like only half as big as the plants in the middle of the system. So this was my first grow with aeroponics. So of coarse I thought it was something to do with that. So I checked and rechecked and rechecked again. And everything was fine. What the heck. Well one night I was just sitting in my flower room. Banging my head against the walls. I just happened to look up. And noticed that the LED light fixture I was using was the exact same size as the demission of all the plants that were growing good. Now every LED light I have purchased was well over a thousand dollars. So you would think they are top of the line. And they are. But here is where the problem is with LED lights. Like I said my aero systems measure 2"9" x 3'. Well the LED light fixture I was using was only 18"x 18". Even though the manufacturer stated that this LED light fixture will cover a 4'x 4' area in 12/12. Which it does project the light that far. But what happens with LEDs is the par in that projected light weakens dramatically the further you get from the diode. Even only a eighth away, the par drops almost half. So what was happening with my grow was the plants in the rows that were only a quarter of a inch away from the diodes were only growing half as big as the plants directly under the diodes. Then the row of plants further away grew smaller than that. Well at that time there was no LED light manufacturer producing a fixture bigger than 2'x 2'. I put 2 of my lights together. But I still had rows that were not directly under the diodes. Plus it was defeating my purpose of wanting to cut my production cost. So I started looking into building my own. How hard can it be. There was plenty of options. But there still wasn't anything as big as I needed. Plus I wasn't impressed with the quality. And I thought shoot for that kind of quality I could get some LED light bulbs and build a better one. Wait what did I just think of ? I started doing some research and bam, it's on. Well I own my own business, so it took me like 8 months before I could find the time to build one. So I had a few complete grows with the LEDs I had. And I was impressed with the final yield and quality. Even though half the plants were suffering. So what I planned to do was just throw one of these lights together using these LED bulbs. So I cut a 3'x 3' piece of half inch plywood. Drilled out the holes for the sockets. I can't remember how many. But it was a lot. Probably close to 30. Lmao 🤣😂. The bulbs I used were a mixture of regular LEDs cool and warm white. And then I mixed in some ( supposedly) true grow light bulbs. I started in one corner with a grow light bulb then went with a regular cool, then a regular warm. Then a grow bulb then a cool and warm then another grow bulb in the other corner. Then went all the way around the outside of the plywood. Then mixed in all the same kind of lights in the middle of the plywood. There is alot of them. I did cut off all the covers off the bulbs. Because. This is probably something that most growers don't know. That ANY kind of lens that covers the diodes can weaken the par up to 30 percent. So my finished bulb light is 650 watts. And I'll tell you what right away I could see that this funky looking bulb light. Actually it looks pretty. Was going to out perform all of my thousand dollar LED lights. And man did it ever. I couldn't believe how much better. The final yield and quality was off the charts. So much so that I built 3 more. Because I have 4 aero systems. This way I have one light over each system. I run these aero systems and lights. Just in my flowering room. I run them on a 2 week rotation. Which means I start one system then 2 weeks later start another and so on till all 4 systems are in 12/12. Then 2 weeks after the forth system is in 12/12. I harvest the first system and start all over again. So in conclusion you will be surprised what you can do with these LED light bulbs. You just have to do some research to make sure you buy the correct ones. I know the question everyone is going to ask. I can't remember how much it cost to build. This was 10 years ago. And you know what ? EVERY light bulb is still growing strong. Take care. And happy growing. ASS OG AeroSystemsSea Of Green.
Yep, my home made light system works as good if not better than the "bought grow lights", it all comes down to light getting into all areas of the plant,
I agree with your conclusion but a single bulb seems good for a comparison experiment while I would think that you need more than that for any serious indoor growing - which seems feasible. I also question the use of single bulbs when they have rectangular arrays of hundreds of LEDS. For $20-$30, you can easily get an adjustable set up that will deliver close to a 1,000 PAR - based, of course, on close you want to keep the lights to your plants.
I think those are very good points. I'd agree, unless you already have the lamps and bulbs kicking around it might make more sense to purchase an array as you've suggested. If you were buying the lamps and bulbs that I have used here the cost difference might not be that different and you'd get much more power from the array.
Very true, good point to mention. Important to note a plant has different needs at different stages of it's lifecycle and in this case I'm highlighting the 2 bulbs for the seedling stage, but someone wanting to go to the flowering stage may need something rather different than I've done.
Walmart sells daylight spectrum LED bulbs in multiple sizes. They even have street lamp replacements in daylight spectrum. Pretty cheap as well. Like 3 dollars for the lowest wattage.
If you want to use standard bulbs to start you should pick 3500/ 4000K CRI95 bulbs (natural colour and with CRI95 it´s pretty much full spectrum). Otherwise there´re cheap grow LED tubes, nothing special but enough to get the plants started, just be carefull with those cheap ones. They´re daisychainable but an end which hasn´t a wire connect has grid power exposed so if going that route, maybe spent a bit extra on some which can´t accidentially kill you. I´d say the reason the "full spectrum" bulb was doing a bit better, you used a 2700/ 3000K bulb which is lagging in blue wavelenght.
Op said the "reg bulb" was 5000k. An idea would be a similar video with 1 plant under plant bulb and a 2700 or 3000k and a 5000k. Maybe I'll try it lol. On paper blue is better for seedlings especially blue-green
@@brianmcdermott2596 Paper doesn´t matter, in reality plants look better and more healthy when given full spectrum even at early stage and even growing just something like lettuce, you want full spectrum and not just heavy blue and barely any red by 5000Ks, the harvest will tell you why. If you got the possibility, do it like other professional growers and do what I also prefer the most: 2:1 mix of warm and cold white; if you´re growing non-bloomers 2x 5000K (or higher if you can find) 1x 3000K (if you can find one even lower than 3K take that) and if its bloomers 2x 3K or lower and 1x 5K or above. As other growers on youtube, I´m most sitisfied with mixing warm and cold, neutral is ok but mixing sure is better over all.
watch mr electroboom touching repeatedly mains power.. hurts ? yes but it does not kill you you die if you grab something with the hand and can not let go or step on electricity and can not step away
If you use a warmer light, more like 4000k instead of the 6000k, there will be no difference between a normal and a growlight. 4000-5000k with a cri of 90 is quite full spectrum 👍🏻 6500k has too much blue and less red - red is more powerful when it comes to thriving.
@@curiousbystander9193 IKEA, called Solhetta, 6W 4000K CRI 90. But why do you need 8W? Grow lights with full spectrum are mostly 25W plus. T8 tubes maybe available in CRI 90 at your store, Philips or Osram for example.
@@PM-wt3ye I have a 200w quantum board running 3000k/6500k with some 660 and 760 nm red. Looking to add some 2700k to the tent with just a few 60w equivalent, low watt led bulbs in small reflector shields... so I wanted to make sure they are 90+ cri,......it doesn;t matter so much whether they are 6 or 8 or even 10 watt leds...... I only really want to add around 25 watts to the tent, but want some spread out 2700k at certain points..... so, ah, yeah, thinking that should compliment my 200w board, which I rarely run above 50% most of the time. Not so much interested to upping the ppfd ,but more so some gentle effects of 2700k during the last month.
@@curiousbystander9193 I think you board is very nice colored, as much as efficient. CRI90 is "necessary", when you only have 4000K, 5000K, 6500K LEDs because there is more red in CRI90 than CRI70-80, but you are additionaly running 3000K and 600nm LEDs, this seems pretty much perfect to me. Those IKEA Solhetta are E27 bulbs, adding something to a board seems to be difficult?!
@@PuraVidaPhotography as much as I hate to rain on your parade because there is not a divider between the two plants to keep the light from assisting the other plant it's not really a valid test. However great job on the video thank you for your time and effort to inform us
Everyone has some old CFL Bulbs or Tubes hanging around. If it's just for starting seeds then save you money and use those. If you want a proper Grow light then get an HPS.
You can get a very significant increase in light output, in my experience at least around 20%, by ripping off the diffuser dome! Usually you can just massage the seam a bit and then pull it off carefully, it's either just clicked in place or secured with some kind of caulk-like glue. Should only be done if you can either ensure nobody touches the lamp or if you insulate it properly though, as it might expose mains voltage carrying bare contacts to the touch. Though it does differ from one manufacturer to the next, the lowest increase I've measured was a bit above 20%, the highest increase was a good bit more than a whooping 50%! Makes the bulbs way more useful without a reflector and they last quite a bit longer as a bonus, after all the plastic dome is a diffuser for a 270° to almost 360° emission characteristic - which is pretty much useless to us in most cases and only leads to unnecessary reflection losses besides swallowing at least 10% (~20% is probably more realistic for cheap mass produced diffusers) of light right away in the plastic material, besides keeping the led chips way hotter than they need to be. Without it most bulbs have a beam characteristic with I'd guess around 80-90% of light in an 80-90° beam, most of the remainder being within 120° - which makes reflectors more or less unnecessary. If you got small kids around, are rather clumsy sometimes and want to use bulbs where you/someone could touch them I recommend either leaving the done on or isolating every single voltage carrying piece of exposed metal with a proper isolating lacquer. Anyway, nice videos. Keep it up!
Can't thank you enough Almost all the sources on the internet indicates "at least get a CFL" but a regular LED bulb works too, as we can see! Do you remember the wattage of the household bulb? And other parameters about it perhaps...
Without a petition to isolate the lights, no correct conclusion can be made. In the beginning You can see the ones on the outside of the regular light grew much slower until the lamps were raised and received more of the grow light.
thanks for a great video , i do have a question , when you said , the full spectrum bulb runs higher , is that initial cost , or electric used ? . your experience is greatly appreicated. , thank you
I've since realized that line was a bit confusing! What I meant was the upfront retail price was higher. Once that's out of the way it draws the exact same amount of power so there would be no further difference in price. Happy it was helpful, thanks for watching!
@@PuraVidaPhotography I forgot to mention I'm growing coleus, planted Nov 12., that I have set on the back of my kitchen stove under the range hood light because I didn't have a grow light when I started them. 10 days tomorrow and they're about an inch tall. This is good, right?
I've never grown that so I can't give too much specific info. But it certainly doesn't seem bad! 10 days isn't that much time but it sounds like whatever you are doing is working. I like that you are using what you have available to get growing too!
Hard to say for certain without knowing much about the specific product. But I would say that if it's and LED type then the watts shouldn't really matter. They will always be much lower than wattage of older style bulbs - but will output an equivalent amount of light. You might want to look into output as a better method of comparison. Happy gardening!
your standard bulb result was leggy because it looks like your spectrum was heavy on the red end of the spectrum.. likely around 3000k.. if you bought a 5000k household bulb that has the same efficiency as your grow bulb, your results would be identical.
Thank you for this video! New to gardening at 58 years old. Starting seedlings indoors right now. I’m on a budget, like you! can you tell me if the standard LED bulb you used was 3000K, 5000k, etc.?
Thank you so much for this video!. I'm trying to grow cat grass for my cat but her in the grass have to stay inside and I was racking my brain over spending extra money on a bulb that might not make a difference
go look at the spectral output for any "white" led... because they work by using a phosphorous coating on a blue or red LED, they are all "full spectrum"... as long as you chose an led with the right ratio of blue to red for the crop and type of growth you're looking for, then any LED will get the job done.. I personally prefer roughly a 4000-5000K spectrum for general applications, 6000 if i want dense growth, and 3000ish if I'm growing leafy greens or flowering plants. One caveat... different leds will have different efficiencies... this will be your most important consideration... number of useable photons emitted per watt used...
@@RasCavv between 8 and 9 watts, not sure but I expect increased watts and increased lumens so a 12 watt LED daylight bulb might work better, 1050 ish lumens.
Hi, we are manufacturer of lighting for plants: dragon fruit, flowers, strawberry, tomato, medicinal plants, herb and vegetables. Where is your farm? And if you need these lamps, plz contact me 😊
The question here is: " Which one is going to gives you tomato?" 😁I grew tomato plants from seed and the ones that were inside did not bear fruit (while they were as tall as me) but the ones that were under the sun did bear fruit.
A very good question! In the end both gave me some but as I had stopped paying close attention I could not say which was the winner. Something I will measure in a future experiment!
This full spectrum was an LED also, I didn't notice much difference in heat with it. Maybe a good thing for other prospective buyers to be aware of though!
It doesn’t seem like a fair experiment if they are of different colour temperature. One has more reds at approx 3000K and the other has more blues. It seems that the warm light could be better for flowering and fruiting.
That's a fair point and I think there is some truth to that. In the context of my video I was looking more at seed starting rather than covering the entire plant lifecycle under the lamp - and whether its worth the extra money for that scenario. I might not have emphasized that enough though! Hopefully it was a bit helpful all the same!
also grow ligt seems better because reds are more photosintetcly active thus getting more growth with same watts but those grow lights are bennefiting from side lighting from the regular bulb you need only 5% of blues to promote less stretch shorter internodals
The standard bulk was 5000k and 60 watt equivalent (the grow light also 60 watt equivalent). Afraid I am not sure about lumens right now though. Hope this helps!
What I've found is common house led bulbs are 400 to 900 lumens. At 7 watts to 10 watts actual draw. The Kelvin is usually 6400k however I have some that are 2200k and 2700k and a 5000k. Also if you take off the plastic diffuser it went up 100 lumens on average. However lumens is not a great measurement for what plants want. The sun is like 20,000 lumens. For plant growing I use ppfd. You need a minimum for most plants of 280ppfd. I measured 8 different bulbs with a photon app and they all came out to 300-600. That's at 12 inches. At 24 inchs it's almost 100ppfd. Grow lights intended for plant's do a far better job then any bulb in my opinion
It won't - unless your indoor plants are getting other ambient light from say a window you would need your lights to be just a few inches above your plants for them to benefit.

Wow, I didn't think it would be that close! I do use LED lights to boost light for my houseplants but to grow plants in my windowless basement I stick to grow lights, this makes me want to conduct an experiment of my own!
Please do, and tag me if so! Gardening is really one life-long experiment and we can all learn from each other.
Have you?
A 6400-6500Kelvin LED Tube is sufficient. Most plants benefit more from the blueish to cold white light spectrum in the early growth stages. Way cheaper and if you place your plants outside later on, it won't matter as they will get the boost from the sun. I started many plants like that from tomatoes to chili. Growth lamps will make a difference if the whole grow cycle of the plant will be under artificial lights as the warmer red spectrum are more beneficial for blooming and fruiting.
Really helpful info,thanks for sharing!
just get a socket splitter 1:7 and mix household cold white with warm wight from dollar tree, even cheaper and you get full spectrum without expense. I do it for interior lightening
what about houseplants that you grow primarily for foliage??
I am using 4000k and they work just fine aswell, for my monstera
@@fredrikhurlen8524 "I am using 4000k"
Same here. I have a permanent setup to keep mother plants, take and keep clones and start seedlings etc.
It runs on a variety of 4000k bulbs of different wattages (with and without diffusers) and sometimes a flat panel bathroom light depending on what's in there, what stage they're at and how close they are to running out of head height.
4000k seems to be the optimum for my purposes.
I've tried them all.
I've a drawer full of all the other colour temperatures if anyone wants them. 🙂
Top tip: Pry those diffusers off the bulbs. I manage to take them off so that I can clip them back on if I want. The increase in light output without the diffusers is substantial.
I've posted this a few times but it seems it's not that widely known: if you take off the plastic defuser you'll get stronger light from the LED bulb.
The easiest and safest way to take off the diffuser is by squeezing it in a bench vice. They can removed by cutting them off but this can be tricky with less favourable results. The diffuser is basically a plastic half ball that's attached with glue so a little pressure in a vice makes it kind of "pop off".
Farming LEDs don't have diffusers so it should be safe to take the defuser off.
Interesting! I'll look into it more, might be a good test to follow this up with. Thanks!
@@PuraVidaPhotography Yes, I good test to do..... and another thought, bulb warranties and liability is void after taking the bulb cover off.
An interesting and informative experiment!
Very good side by side.They both look nice I'm impressed with your growing skills.😊
Thanks and glad it was helpful!
Take the diffuser off and get about 10% extra lumens.
Awesome, good tip!
Great video! Thank you.
mucking about with home lighting as grow lights is a waste of time and money.
you really need a super bright light source for getting plants started, else they will not grow well. The amount of lumens in proper grow lights is insane, compared to house lighting globes. one of my one foot square led growlights is 150W, hanging comfortably a foot and half above seedling tray.
i tried mucking about before with led shop lights etc., and they were a waste of money and time, producing dissapointing results.
save that money, and buy proper growlight.
I'd have to agree that if starting with nothing it wouldn't make sense to 'invest' in the home lighting solution I showed. As you say, just not that effective for what you'd spend. My idea was more in terms of re-purposing existing things around your house: old lamps and bulbs, which might allow you to give seedlings a bit of a boost you'd otherwise not have. But yes, I'd like to showcase the difference that can be had with a proper lighting system in the future. Thanks for watching!

@PuraVidaPhotography Is not a true accurate comparison test because you are using two different lamps. Is your slight "more robust' plant grown with the grow bulb due to the bulb performance or the lamp that was used? One way to find out and make you comparison test experiment more accurate is to repeat your test but switch the light bulbs to the opposite lamps and ddocument your results. Maybe in the next test, the grow bulb will not be producing a more robust plant when switched to the other lamp and if so, then the results of this video post and my suggested comparison test #2 would perhaps be the performance of two different lamps? A better comparison test suggestion is to used exactly the same lamps preferably tested at the same time side by side. Any equipment used in a comparison test should be the same EXCEPT the variable which in this case would be the different light bulbs that your testing.
one thing I can say with these full spectrum lights : ur plants will die if you overuse the light. I was wondering why all my plants kept dying, I was falling asleep with their lights on some days. They need like idk 12 hours a day with these, with like maybe 16 max, anymore ur risking damage, and they need to sleep everyday with lights out.
That's a great point! I had the lights on a timer for about 16 hours max /day. It's important to give them a break for sure.
I've tried CFL's, cool and warm. Incandescent, cool and warm. LED, cool, daylight and warmer. An LED actual grow light. I've even mixed color temperatures in the same fixture. They all work fine but the timing is critical. I usually start too early for my zone. Wish more people would grow gardens in my area. It's getting quite rare lately.
Another early bird. Same here, every dang year! I'll never stop though for that early excitement into a new season!
6400-6500k for all plants is best. but ya any grow light will work. I got some bright 6500k bulbs in fixtures. Sunlite 80728-SU LED A21 Super Bright Light Bulb 1600 Lumens, 15 Watt (100W Equivalent), Dimmable, Medium Base (E26), UL Listed, 1 Pack, 65K - Daylight and I also like those amazon ones with the small white square rectangles that have a vice clamp for windows sills and tables with two of them snaking out. Those long round colored tube ones stay away from. They fade over time or start blinking forcing you to lower the light intensity or they just die altogether. Those other ones I mentioned though last for years. 6 years for me 12 hours a day 4 sets from two different companies. relassy and bozily. every one of those colored tube lights I got from various manufacturers died in a year or two and they never got as bright from the start.
@@cooloutac great info, thank for sharing!
Thank you, I'm about to buy some lights for my house plants because I ran out of space under the windows. It's kind of relief to see it's not that significant. I didn't even know regular lightbulb is enough for them.
You are very welcome!
I agree. Now I can move some plants to new locations in my space.
Old school, flourescent lights work great as well. My granny would keep her plants alive in the garage during the winter with just a flourescent light above them.
I'm curious about the ambient light mix, maybe a separated space will be an experiment I'll try on my own.
Guys don't let the term grow light deceive you there are normal house light with the same specifications and just as much efficiency as some of the really budget so called grow lights
This is a good point. Marketers like to complicate things. I have been think about revisiting this looking at more of the 'regular' bulbs. But in the mean time the point stands: any old light bulb is probably good enough for starting seeds!
How far apart were each? Or were they close enough that the full spectrum bulb was able to care for both, filling the void of the standard LED bulb?
The lights were about 2 feet away from each other. I felt there was minimal, if any chance of light spillover affecting the other group in this case as typically you want your grow lights as close as possible, and there was only minimal, indirect light coming to the opposite group. Reason I kept them relatively close was so that they would get the same amount of ambient light and not skew results that way.
The one flaw to this experiment is that they are both in the same roon, close enough to each other, that the indirect light from both light sources can influence the growth of all the plants.
For more accurate results... you should grow the plants in separate rooms, each with a different light source.
We did this same experiment in my botany class. The plants were seperated into 2 groups, in seperate rooms... 1 room with grow lights, & the other room lit with 6000k LED lights.
After 8 weeks... both groups of plants were equally strong & healthy, under both lighing conditions... but the plants grown under the grow lights were on average 40% larger.
The plants under the grow lights produced more sugars, because a much greater percentage of the light output from the grow lights is in the Blue & Red spectrums, than what the normal white LEDs produced.
You're correct, and that is something I hope to rectify next time around. That's really interesting to hear about the results you found in your class too!
GE makes LED light bulbs in different color spectrums ranging from warm to cool. I need supplemental light for my orchids and other flowering plants and combined bulbs with blue and red ranges in floor lamps and it’s working quite well. They’re not marketed as grow lights but pretty much accomplish the same thing, IMO. I have an LED lamp but it is too bright and the light is so blue that it gave me a headache. My plants are responding well. Although my setup was not expensive, it works for me. The output is around 1500 FC which is pretty bright. I thought I might experiment with summer annual seed starting as well.
That's great, it sounds you've got a system working well!
I've been growing cannabis indoors for a little over 30 years.
When LEDs came out of coarse I purchased a few.
To try and cut my electricity cost.
So over the years I have spent thousands on numerous supposedly high end LEDs.
Well about 12 years ago I decided to give aeroponics a try.
So I started designing my own aero systems. As I was doing this I could see it would be more efficient to grow in what is called the Sea Of Green ( SOG ).
Which means you grow your plants very close together.
For example, in my aero systems my plants are a little less then 2" apart.
My aero systems measure
2'9"x 3' so lets say 9 s/ft.
In that 9 s/ft I have 46 plants.
You might be saying " well what the hell good is that".
First off I am using every single bit of light that the fixture is producing.
And next, when you grow in the SOG, you are concentrating on the main top of the plant, which is always the most potent and produces the biggest bud.
So in my 9 s/ft area I'm getting 46 main tops compared to the normal of growing 1 plant in that same area and getting only one main top.
Now I'm sure hear, there is going to be people making comments that you can train your plants to get a even canopy. Yes you can.
And it's a total waste of time. And adds a tremendous cost on to your final product.
No matter how you train the plant, you are still only going to get one main top.
So now finally I'm going to get to the point of this long story.
So once I started growing with my aero Systems. Right away I was seeing a problem. And it was very strange. All the plants all the way around the outside edge of my aero Systems. Like 3 rows of plants all the way around. Were suffering. They weren't growing good. They were like only half as big as the plants in the middle of the system.
So this was my first grow with aeroponics. So of coarse I thought it was something to do with that.
So I checked and rechecked and rechecked again. And everything was fine.
What the heck.
Well one night I was just sitting in my flower room. Banging my head against the walls. I just happened to look up. And noticed that the LED light fixture I was using was the exact same size as the demission of all the plants that were growing good.
Now every LED light I have purchased was well over a thousand dollars. So you would think they are top of the line. And they are.
But here is where the problem is with LED lights.
Like I said my aero systems measure 2"9" x 3'. Well the LED light fixture I was using was only 18"x 18".
Even though the manufacturer stated that this LED light fixture will cover a 4'x 4' area in 12/12.
Which it does project the light that far.
But what happens with LEDs is the par in that projected light weakens dramatically the further you get from the diode. Even only a eighth away, the par drops almost half.
So what was happening with my grow was the plants in the rows that were only a quarter of a inch away from the diodes were only growing half as big as the plants directly under the diodes. Then the row of plants further away grew smaller than that.
Well at that time there was no LED light manufacturer producing a fixture bigger than 2'x 2'.
I put 2 of my lights together. But I still had rows that were not directly under the diodes. Plus it was defeating my purpose of wanting to cut my production cost.
So I started looking into building my own. How hard can it be.
There was plenty of options. But there still wasn't anything as big as I needed. Plus I wasn't impressed with the quality.
And I thought shoot for that kind of quality I could get some LED light bulbs and build a better one.
Wait what did I just think of ?
I started doing some research and bam, it's on.
Well I own my own business, so it took me like 8 months before I could find the time to build one.
So I had a few complete grows with the LEDs I had.
And I was impressed with the final yield and quality.
Even though half the plants were suffering.
So what I planned to do was just throw one of these lights together using these LED bulbs.
So I cut a 3'x 3' piece of half inch plywood. Drilled out the holes for the sockets. I can't remember how many. But it was a lot.
Probably close to 30.
Lmao 🤣😂.
The bulbs I used were a mixture of regular LEDs cool and warm white. And then I mixed in some ( supposedly) true grow light bulbs.
I started in one corner with a grow light bulb then went with a regular cool, then a regular warm. Then a grow bulb then a cool and warm then another grow bulb in the other corner. Then went all the way around the outside of the plywood.
Then mixed in all the same kind of lights in the middle of the plywood. There is alot of them.
I did cut off all the covers off the bulbs.
Because.
This is probably something that most growers don't know.
That ANY kind of lens that covers the diodes can weaken the par up to 30 percent.
So my finished bulb light is 650 watts.
And I'll tell you what right away I could see that this funky looking bulb light.
Actually it looks pretty.
Was going to out perform all of my thousand dollar LED lights.
And man did it ever.
I couldn't believe how much better.
The final yield and quality was off the charts.
So much so that I built 3 more.
Because I have 4 aero systems. This way I have one light over each system.
I run these aero systems and lights. Just in my flowering room.
I run them on a 2 week rotation. Which means I start one system then 2 weeks later start another and so on till all 4 systems are in 12/12.
Then 2 weeks after the forth system is in 12/12.
I harvest the first system and start all over again.
So in conclusion you will be surprised what you can do with these LED light bulbs.
You just have to do some research to make sure you buy the correct ones.
I know the question everyone is going to ask.
I can't remember how much it cost to build. This was 10 years ago.
And you know what ?
EVERY light bulb is still growing strong.
Take care.
And happy growing.
ASS OG
AeroSystemsSea Of Green.
Yep, my home made light system works as good if not better than the "bought grow lights", it all comes down to light getting into all areas of the plant,
Will a string of lights work the same? I'm thinking so. I'm a chick so I can't build such a contraption or use a power drill. I'm scared.
@@SRFarming420
It's better than nothing.
@@SRFarming420No, it's not really gonna work. It might look pretty though..
I agree with your conclusion but a single bulb seems good for a comparison experiment while I would think that you need more than that for any serious indoor growing - which seems feasible. I also question the use of single bulbs when they have rectangular arrays of hundreds of LEDS. For $20-$30, you can easily get an adjustable set up that will deliver close to a 1,000 PAR - based, of course, on close you want to keep the lights to your plants.
I think those are very good points. I'd agree, unless you already have the lamps and bulbs kicking around it might make more sense to purchase an array as you've suggested. If you were buying the lamps and bulbs that I have used here the cost difference might not be that different and you'd get much more power from the array.
When it comes to flower, the grow light has what’s needed, the red. The standard 5000k has very low red.
Very true, good point to mention. Important to note a plant has different needs at different stages of it's lifecycle and in this case I'm highlighting the 2 bulbs for the seedling stage, but someone wanting to go to the flowering stage may need something rather different than I've done.
@@PuraVidaPhotography yeah, for houseplants, propagation, and germination, definitely save your money!
To help strengthen the stems you really need a fan as well. Wind is an important strengthener of stems. Thank you for your comparison video!
That's very true, I plan to incorporate that next year.
This was just what i was looking for.... great experiment! many thanks :)
Glad it was helpful & best of luck with the garden!
Walmart sells daylight spectrum LED bulbs in multiple sizes. They even have street lamp replacements in daylight spectrum. Pretty cheap as well. Like 3 dollars for the lowest wattage.
Very true, there are some frugal options out there that will work well!
Much appreciated thanks bro good video quiet impressed ❤❤❤❤❤❤❤
Very welcome, thanks for watching!
If you want to use standard bulbs to start you should pick 3500/ 4000K CRI95 bulbs (natural colour and with CRI95 it´s pretty much full spectrum). Otherwise there´re cheap grow LED tubes, nothing special but enough to get the plants started, just be carefull with those cheap ones. They´re daisychainable but an end which hasn´t a wire connect has grid power exposed so if going that route, maybe spent a bit extra on some which can´t accidentially kill you. I´d say the reason the "full spectrum" bulb was doing a bit better, you used a 2700/ 3000K bulb which is lagging in blue wavelenght.
Great info and observation. I'm curious to retry with 3500/4000k bulb soon!
Op said the "reg bulb" was 5000k. An idea would be a similar video with 1 plant under plant bulb and a 2700 or 3000k and a 5000k. Maybe I'll try it lol. On paper blue is better for seedlings especially blue-green
@@brianmcdermott2596 Paper doesn´t matter, in reality plants look better and more healthy when given full spectrum even at early stage and even growing just something like lettuce, you want full spectrum and not just heavy blue and barely any red by 5000Ks, the harvest will tell you why. If you got the possibility, do it like other professional growers and do what I also prefer the most: 2:1 mix of warm and cold white; if you´re growing non-bloomers 2x 5000K (or higher if you can find) 1x 3000K (if you can find one even lower than 3K take that) and if its bloomers 2x 3K or lower and 1x 5K or above. As other growers on youtube, I´m most sitisfied with mixing warm and cold, neutral is ok but mixing sure is better over all.
@@gedeuchnixan3830 thanks for the info, always appreciated
watch mr electroboom touching repeatedly mains power.. hurts ? yes but it does not kill you
you die if you grab something with the hand and can not let go or step on electricity and can not step away
If you use a warmer light, more like 4000k instead of the 6000k, there will be no difference between a normal and a growlight. 4000-5000k with a cri of 90 is quite full spectrum 👍🏻
6500k has too much blue and less red - red is more powerful when it comes to thriving.
Good to know!
who makes cri 90+ for little 8 watt leds?
@@curiousbystander9193 IKEA, called Solhetta, 6W 4000K CRI 90. But why do you need 8W? Grow lights with full spectrum are mostly 25W plus.
T8 tubes maybe available in CRI 90 at your store, Philips or Osram for example.
@@PM-wt3ye I have a 200w quantum board running 3000k/6500k with some 660 and 760 nm red. Looking to add some 2700k to the tent with just a few 60w equivalent, low watt led bulbs in small reflector shields... so I wanted to make sure they are 90+ cri,......it doesn;t matter so much whether they are 6 or 8 or even 10 watt leds...... I only really want to add around 25 watts to the tent, but want some spread out 2700k at certain points..... so, ah, yeah, thinking that should compliment my 200w board, which I rarely run above 50% most of the time. Not so much interested to upping the ppfd ,but more so some gentle effects of 2700k during the last month.
@@curiousbystander9193 I think you board is very nice colored, as much as efficient.
CRI90 is "necessary", when you only have 4000K, 5000K, 6500K LEDs because there is more red in CRI90 than CRI70-80, but you are additionaly running 3000K and 600nm LEDs, this seems pretty much perfect to me.
Those IKEA Solhetta are E27 bulbs, adding something to a board seems to be difficult?!
Would be interesting to add a 3rd setup with no lights at all in the same environment
That's a good idea, I could definitely consider doing a further test and incorporating that.
@@PuraVidaPhotography as much as I hate to rain on your parade because there is not a divider between the two plants to keep the light from assisting the other plant it's not really a valid test. However great job on the video thank you for your time and effort to inform us
I can tell you what you would get. Leggy laying over seedlings.
Thank you for this! Just started learning about home gardening, very interesting video.
Very welcome and best of luck with your garden!
You can remove the globe from the lightbulb and get a bit more par.Just prise or cut it off👍
I veg my cannabis plants this way and you can flower as well 😎🇨🇦
Thanks for the information. I would put silver bubble wrap behind the plants.
No worries & that would certainly would help!
How strong is standard led"? And does it have 6500k ?
Thank you! I've been thinking of just using regular led lights than grow light. Grow lights are too expensive!
Very welcome, and best of luck!

@@PuraVidaPhotography pura vida MAE 😀
You didn't cover your nice oak table?
I think it looks nicer than it actually is! :D
Temperature of heat coming from light also makes a large difference I think what are the temperatures.
Everyone has some old CFL Bulbs or Tubes hanging around. If it's just for starting seeds then save you money and use those.
If you want a proper Grow light then get an HPS.
Agree!
Should I use cool white or warm white?
I dont think it'll matter too much. Whatever you have on hand!
What colour temperature was the standard bulb?

Thanks for your support!
Beautiful video, thank you very much! your voice is so sweet!
You're welcome, thanks for swinging by!
You can get a very significant increase in light output, in my experience at least around 20%, by ripping off the diffuser dome!
Usually you can just massage the seam a bit and then pull it off carefully, it's either just clicked in place or secured with some kind of caulk-like glue.
Should only be done if you can either ensure nobody touches the lamp or if you insulate it properly though, as it might expose mains voltage carrying bare contacts to the touch.
Though it does differ from one manufacturer to the next, the lowest increase I've measured was a bit above 20%, the highest increase was a good bit more than a whooping 50%!
Makes the bulbs way more useful without a reflector and they last quite a bit longer as a bonus, after all the plastic dome is a diffuser for a 270° to almost 360° emission characteristic - which is pretty much useless to us in most cases and only leads to unnecessary reflection losses besides swallowing at least 10% (~20% is probably more realistic for cheap mass produced diffusers) of light right away in the plastic material, besides keeping the led chips way hotter than they need to be.
Without it most bulbs have a beam characteristic with I'd guess around 80-90% of light in an 80-90° beam, most of the remainder being within 120° - which makes reflectors more or less unnecessary.
If you got small kids around, are rather clumsy sometimes and want to use bulbs where you/someone could touch them I recommend either leaving the done on or isolating every single voltage carrying piece of exposed metal with a proper isolating lacquer.
Anyway, nice videos. Keep it up!
Wow that is some really relevant and useful information. Thank you for sharing! This has me excited to try!
The one thing I will always say to indoor horticultural grows, go out and purchase a good quality brand you'll be happier for it 💯 🌿🇬🇧
Absolutely!
Can't thank you enough
Almost all the sources on the internet indicates "at least get a CFL" but a regular LED bulb works too, as we can see! Do you remember the wattage of the household bulb? And other parameters about it perhaps...
So glad it was helpful for you! The bulb was 9 watts, equivalent to a 60w incandescent.
I bought daylight LED brightness 760 lumens for my ceiling lights. Are these sufficient to keep my plants alive on cold days?
Not unless you plan to hold your plants about 6 inches from them 8-10 hours a day!
Full spectrum lights is as close to natural sunlight, won't be surprised that the nutrients value of the final product would be different also.
That would be a fantastic thing to compare next time around!
what is the power of the standard LED bulb you used?? (in watts)
8 watts
@@PuraVidaPhotography can you give the exact name and info of the grow led and standard led used in this video?
Thanks 😊
Very welcome!
The mutispectum LED grow bulb ones look little more healthier then average bulb.
I think it's possible they had a slight edge. Definitely minor though!
I combine the two, my phalinopsis is flowering in wintertime super stoked.
That's fantastic!
Without a petition to isolate the lights, no correct conclusion can be made. In the beginning You can see the ones on the outside of the regular light grew much slower until the lamps were raised and received more of the grow light.
Yep and you can see the leaves reaching for the grow light bulb
Pop the diffuser off and you have a raw led board but don't get a shock
Sounds interesting, would like to look into this more!
Thanks for doing this experiment so that we don’t have to do it.
It helped me a lot.
So glad it was helpful!!
thanks for a great video , i do have a question , when you said , the full spectrum bulb runs higher , is that initial cost , or electric used ? . your experience is greatly appreicated. , thank you
I've since realized that line was a bit confusing! What I meant was the upfront retail price was higher. Once that's out of the way it draws the exact same amount of power so there would be no further difference in price. Happy it was helpful, thanks for watching!
@@PuraVidaPhotography thank you ,
You can grow a plant with with regular incandescent bulb. Not a good plant but it will grow for a while
Life uhh, finds a way :D
It looks like the grow light is burning them
if you use something like this deffo remove plastic dome as the leds itself are 120 degrees
Good call, will try that
I love how you're gardening in a beautiful living area like it ain't no big thing 😅 Thanks for a great video 🙂
Couldn't agree more, I'm incredibly lucky to live here! Glad you enjoyed and happy gardening!
@@PuraVidaPhotography I forgot to mention I'm growing coleus, planted Nov 12., that I have set on the back of my kitchen stove under the range hood light because I didn't have a grow light when I started them. 10 days tomorrow and they're about an inch tall. This is good, right?
I've never grown that so I can't give too much specific info. But it certainly doesn't seem bad! 10 days isn't that much time but it sounds like whatever you are doing is working. I like that you are using what you have available to get growing too!

@@eddiewest8477 very welcome!
i have a plan to buy a 90 cm length grow light with 15 watt spec. i am not sure with the quality because it is only 15 watt power. how about it?
Hard to say for certain without knowing much about the specific product. But I would say that if it's and LED type then the watts shouldn't really matter. They will always be much lower than wattage of older style bulbs - but will output an equivalent amount of light. You might want to look into output as a better method of comparison. Happy gardening!
@@PuraVidaPhotography thanks !!! appreciate that..
try using reflective material which multiplies the light
Good call, would definitely look into that next go around.
your standard bulb result was leggy because it looks like your spectrum was heavy on the red end of the spectrum.. likely around 3000k.. if you bought a 5000k household bulb that has the same efficiency as your grow bulb, your results would be identical.
Havent understood the light cycle
18/6?
Correct, yes
good experiment tnX
Fantastic demonstration, very sensible. Thanks.
Glad it was helpful!
may be for be more correct this test, need to put somehing in the middle that not mixing lights between the 2 groups
break off the diffuser and the light is stronger
Will give that a try!
Thank you for this video! New to gardening at 58 years old. Starting seedlings indoors right now. I’m on a budget, like you! can you tell me if the standard LED bulb you used was 3000K, 5000k, etc.?
Awesome, its a great hobby! The bulb was 5000k
I smell crap right through the phone
You might want to stop bringing it into the bathroom with you and give it a good wipe down.
But we're both those bulbs the same watts
yes
3500 -5000 k
very interesting, thank you for sharing
Glad it was helpful!
? what wattage are your bulbs
They are 8 or 9 watt led - equal to a 60w incandescent bulb
Thank you so much for this video!. I'm trying to grow cat grass for my cat but her in the grass have to stay inside and I was racking my brain over spending extra money on a bulb that might not make a difference
Very welcome, glad it helped and hope your kitty is happy with the results!
go look at the spectral output for any "white" led... because they work by using a phosphorous coating on a blue or red LED, they are all "full spectrum"... as long as you chose an led with the right ratio of blue to red for the crop and type of growth you're looking for, then any LED will get the job done.. I personally prefer roughly a 4000-5000K spectrum for general applications, 6000 if i want dense growth, and 3000ish if I'm growing leafy greens or flowering plants.
One caveat... different leds will have different efficiencies... this will be your most important consideration... number of useable photons emitted per watt used...
Good info, thanks for adding!
Thank you for uploading this amazing video now I can see what I have waiting for. Thanks again
Very welcome!
what was the lumen of the bulbs on this video? the ones i have home don't seem to be enough for anything😅
It was 800 lumens for each bulb
@@PuraVidaPhotography thanks so much and happy new year🙌
@@PuraVidaPhotography so I expect them to be ~9 W each. Is it correct?
@@RasCavv between 8 and 9 watts, not sure but I expect increased watts and increased lumens so a 12 watt LED daylight bulb might work better, 1050 ish lumens.
Hi, we are manufacturer of lighting for plants: dragon fruit, flowers, strawberry, tomato, medicinal plants, herb and vegetables. Where is your farm? And if you need these lamps, plz contact me 😊
The question here is: " Which one is going to gives you tomato?" 😁I grew tomato plants from seed and the ones that were inside did not bear fruit (while they were as tall as me) but the ones that were under the sun did bear fruit.
A very good question! In the end both gave me some but as I had stopped paying close attention I could not say which was the winner. Something I will measure in a future experiment!
The LED bulb doesn't emit heat, whereas the full spectrum does, so that is another factor that should be taken into account.
This full spectrum was an LED also, I didn't notice much difference in heat with it. Maybe a good thing for other prospective buyers to be aware of though!
It doesn’t seem like a fair experiment if they are of different colour temperature. One has more reds at approx 3000K and the other has more blues. It seems that the warm light could be better for flowering and fruiting.
That's a fair point and I think there is some truth to that. In the context of my video I was looking more at seed starting rather than covering the entire plant lifecycle under the lamp - and whether its worth the extra money for that scenario. I might not have emphasized that enough though! Hopefully it was a bit helpful all the same!
also grow ligt seems better because reds are more photosintetcly active thus getting more growth with same watts but those grow lights are bennefiting from side lighting from the regular bulb
you need only 5% of blues to promote less stretch shorter internodals
Good food for thought
What are the specs on the standard led bulb K, LMN ,Watt equivalent Watt
The standard bulk was 5000k and 60 watt equivalent (the grow light also 60 watt equivalent). Afraid I am not sure about lumens right now though. Hope this helps!
What I've found is common house led bulbs are 400 to 900 lumens. At 7 watts to 10 watts actual draw.
The Kelvin is usually 6400k however I have some that are 2200k and 2700k and a 5000k.
Also if you take off the plastic diffuser it went up 100 lumens on average.
However lumens is not a great measurement for what plants want. The sun is like 20,000 lumens.
For plant growing I use ppfd. You need a minimum for most plants of 280ppfd. I measured 8 different bulbs with a photon app and they all came out to 300-600. That's at 12 inches. At 24 inchs it's almost 100ppfd.
Grow lights intended for plant's do a far better job then any bulb in my opinion
Helpful info, thanks!
thank you so much love this video you dont know how much you helped me with LEDs
Im glad it helped!
Nice work! I rotate my plants under lights and try to have a grow tent for reflection or two lights for coverage.
Thanks! I think a grow tent and regular rotation would be a great benefit too!
That is massive. I already heart this from another YTer and I felt busted for buying expensive grow bars.

It won't - unless your indoor plants are getting other ambient light from say a window you would need your lights to be just a few inches above your plants for them to benefit.

10-15 years ago it was all about lumens but I don't hear anyone mention it anymore
