@uncle dunk I didn't say not to use CO2. I was sharing a tip for estimating the PPF requirements for growers who aren't using CO2. If a grower is using CO2, then the plants would be able to utilize more photons and the PPF / PPFD / DLI levels can be higher.
MarsHydro FC/FC-E lineup is extremely good. I have a FC4800 in a 4x4, I don't have a par meter but the spread looks insanely even across the whole tent.
@@jonbgreen6916 As shown in this video, the light requires a certain amount of vertical height for optimal coverage. This makes it great for commercial growing in an open warehouse style layout. The primary situation where bar lights excel would be for tight vertical clearances like racks. Otherwise, there's really no reason to stay away from this type of light.
I bought the sf 4000 to grow herbs and it's doing great.i have a fan constantly blowing on the top power supplies to keep them really cool and hopefully make it last alot longer.i bought it because of your review of it.thanks
Hello AlboPepper, to be honest, I am amazed by your reviews. I searched a lot for different lamps reviews and so on. But no one delivered like you did. I started to check out your other videos too and wow ... they are so great. I am so happy that I found you. I studied physics. I am German. I need proper reviews with details, going into the specs. You are the one delivering it. You are outstanding and awesome.
I’ve purchased 2 SF2000’s (both from your links) and I am very happy with them! So easy to use and my plants have been phenomenal-can’t ask for more than that. Thanks!
Hey gracien, just want to say goodluck to you. My community and myself included just suffered a very bad harvest failure, it have been raining non stop here and it caused a lot of flooding that damaged a lot of plants and the one that survive dies from fungal or bacterial infection, it's especially bad considering the state of the world right now so I'm wishing nothing that happened here ever happen to you
I just received my SF4000 today, glad I found your video today as I was setting it up. I am a little perplexed as to setting the distance though. My setup is a 4x4 grow tent. I have several items in there but more importantly I have a chili plant in hydro that’s flowering but wondering as too optimal distance and dimmer setting. I currently have it set to about 18in per the manual. Eventually I will move the other items out once last freeze is safely gone for my zone.
i agree 100%. i even bought one for $400 and it didnt compare to the sf4000 side by side so that mixjoy without dimmer went back and got me another sf. Took me awhile to be convinced about leds but after the results of 2 sf4000's runs I am a believer.
@@brianfyffe8204 the appropriate question would be, what is your square footage. All plants require different amounts of light to flourish. Example, lettuce versus "tomatos".
I have had an older model sf 4000 (dimmer under the drivers) so I’ve used it only at full power for a year now. I grow auto flowers and I’ve come to find out that using it as I have is just fine as long as it is never closer than 20” at any point in the grow cycle. That said, I highly recommend Spider Farmer in general, especially for the price point.
Thanks to you and migro I think there's a lot off people that ain't gettripped off thanks to you both,I sold mh hps but now young folks want leds mars spider vivosun hlg bloomplus I like the mars if you can get it cheap enough
Great figures breakdown, very informative, easy to understand and super helpful! Abs love it, lots of really valuable info, excellent for newbies, keep doing more! 👌
I am just about to get back in the swing of things and am about to get an sf 1000 wt led. Awesome info. Just discovered you as well. Subscribed and lovin your output. Thanks, man.
Thank you for your wonderful Content as It is so helpful to the new grower. I just purchased a SF 2000 spider farmer light as well as a 2 x 4 grow tent for auto flowers. Hoping you can share with me your favorite light hanging height and intensity on the dimmer knob for the seedling, veg, and flower stages of the plant.
This upgrade is a long time coming friends 👍 I have burned some medicinal peppers with the sf 4000 turned down to two hundred and seventy-five ish Watts. I would have been more prone to turn the intensity back sooner if my light has this upgrade. The very next run I decided to go back to my blurple for veg and save the sf 4000 for flower. It’s a strong light for sure worth the money once I figure the height out better.
he only US labor on an HLG is loading the Japanese LED board stuffers and putting quantum boards into a shipping. box. The LEDs and and PC board are all made overseas.
@@Albopepper Thank you for responding ... we enjoy your videos. btw... can you do a video on how much the the Samsung/Osram LED fixtures dim over time? For all I know 2 years down the road they lose 20 percent lumen so your stuck with a brick. I want to migrate from HPS but nobody has done long term. Do have and links to long term test? Thank you a million, Mack
The term to search for is "lumen maintenance." The LM301B diodes are marketed for being both highly efficient and also for having higher lumen maintenance vs many other diodes on the market. I'd love to see more info on the topic as well. I've had to dig through various product specification pages and even still, it's hard to get concrete numbers and specs for comparison. I know the Samsung diodes perform very well in this regard, but I have yet to find a complete database comparing multiple diode brands and models, let alone when compared to other tech like HIDs and fluorescents.
the new 2021 sf 4000 has way better light distribution they spread the diodes in the center and packed them in tight around the corners. you can get really good par values on the edge's without getting too hot in the center. glad to see spider farmer taking feedback on their lights and making improvments.
I’ve got 2 of these mounted on light movers in tents. I am very much using them wrong, but because I know how I’m using them wrong, I’m using them “right” for what I’m doing. I’ve got one fixture per 4x8, and have some shadows as it moves all the way. But, i do think this can cover a 4x6 tent on a mover and give the maximum potential yeild the light can with relative ease.
Thanks for sharing the last thing I need to complete my I door growing set up this winter has been the lights so much misleading online it's hard to decide what light set up to buy
Hypothetical question: If I make an array of ultra-high-efficiency home-lighting LEDs, like the one you show at 6:23 (say in the 120 lumen per watt category), would these be an okayish alternative for grow-lights? If I supplement the warm-white with a few "special" LEDs, say 395nm or 750nm, would it make growth meaningfully better? I'm not looking for "medicinal" plants, just kitchen-garden herbs; the ridiculously cheap home-lights (2024) are skewing the "bang for the buck" story, imo.
My SF4000 only covered an actual 3'x3' area in flower, with the center being way too intense. The outlying 1'x1' area of the tent was a total waste. I replaced it with a Mars Hydro FC4500 that actually covered the 4'x4' and the difference in yield was impressive in addition to being a really good light. They nailed this design and I hope you can test and review them soon.
Thanks for sharing your experience with this model. What you're describing matches up perfectly with what I said in this video. If your center readings were too high and the outer edges were poorly lit, then your light was too close. That's the light physics of this unit. It should have been raised higher for more even coverage. I'm at Mar Hydro's site right now & I don't see anything for an FC4500. But I DO see an FC4800. That type of model is _EXCELLENT_ for even coverage at much lower hanging heights. It should be positioned totally differently than the SF4000. I don't agree with the specs for the FC4800 though. The Par Value seems to me, to be fabricated. I don't believe this light puts out 1649 umols while drawing 480W. That would mean 3.44 umols/J. I don't believe it. And so I have difficulty trusting their listing...
@@Albopepper Sorry... I confuse the 4800 and 6500 model numbers because I have them both. As for having the SF4000 too close, there are limits to the hanging height inside of a tent due to the wire hangers so I can agree to a point... But even raising that style of light higher will only moderately raise the readings at the edges of the fixture; you simple cannot have proper intensity where there are no diodes which is why I prefer the strip style fixtures. I'm sure the Mars readings are not 100% accurate either, but what I'm seeing on my meter is more than enough for flowering even at extreme levels over the entire 4'x4' area... Which was not the case for the SF4000. Real world, it simply wasn't enough coverage for a 4'x4' growing cannabis to the results I expect.
No worries about the model number! At least I was able to figure out which one you meant. Being physically constrained by hanging height is a real issue. I'm glad you brought this up. Hopefully it will inform others who have vertical limits in their tent size. In your situation, it sounds like you made the perfect choice by switching to a system that has a broad diode layout. What was the distance that you had between the SF4000 and the plant canopy? That info might be able to help out other viewers. No CO2, right?
@@Albopepper Hanging height is a big issue with these kinds of intensity (especially without knob dimming), and this was in a full size 8'x4'x7' tent... The SF4000 was 14-16" from the majority of the canopy, so it was not especially close. I didn't see any bleaching or other signs of the light being too intense, but I could not move the light higher without discarding the wire hangers... We could really use a low profile hanger to make use of the extra foot of space. I don't run Co2 in that tent, but it does average about 600ppm+/- due to it's location inside, so I think I fared better with light stress than would otherwise happen.
Thanks for that! So planning on 18" as a minimum was good advice then. But yeah, custom hanging wires might be needed to achieve it. In my little ghetto grow chamber I had to do exactly that to conserve space. I ditched the OEM wires and used some hanging chains instead.
Vids like this one sometimes make me really angry. And all because I can give only one like :P Excellent content, super informative - subbed! Keep up the amazing work
Nice video with solid info! It's obvious that experienced grower's knowledge exceed the one of an average marketing department employee 😊💚🐛. Btw. there is some benefit in using two SF2000 (or four SF1000) lights instead one SF4000. With multiple lights you can get more even spread (less hot spot).
Thanks for watching! If your growspace is rectangular then the SF2000s are certainly going to be more flexible for creating uniform coverage. In a perfectly square tent, there's less advantage to using the 2000s. Perhaps if there is very little vertical clearance then the 2000s might work out just a little better. But with a my smaller tent size recommendations, along with sufficient hanging height, the SF4000 will do rather well.
The fact that you could even get ahold of Samsung to find out the reason for price fluctuations is amazing. Gives me faith that someday I might be able to source leds from them. Hahah JK prob not. Idk if it’s because of Covid but I can’t even get the led stars, or individual diodes to reflow myself that I’m looking for. I just made one 730nm module to add to my HLG650R lights. I wanted to see if I could do it first( never even soldered until now) so I only ordered 21 triple 20mm star mcpcb for a small Slate single QB648 light. I’m trying to go 1:1 wattage wise with the 730nm to Quantum Board total( I know it’s not commonly used at all let alone at this level )
Another great review and appreciated. Nice job! Might have been an improvement for Spider Farmer to space the four boards out, instead of clustering them for better corner coverage and more even lighting.
Good observation Matt! Yes, spacing out each board would provide more even coverage. That would be most crucial for growers who are limited on vertical space.
Some types of plants can do ok under 24hr light cycles. But not all plant. Many of the high light flowering plants require a 12/12 cycle to complete their reproductive phase. Something to keep in mind.
Great and honest review as always. I do wish Spider Farmer would come out with linear/rail version (e.g 3"x 4' or 2') that would allow us to change the configuration around for something other than a square tent. Until then I'll just have to keep building my own
The original way to dim was a total joke and waste of time, but the upgrade is now exceptionally awesome, good save Spider farm I'm buying a grow kit once I sell this guitar on Ebay Australia :-)
LOL, thanks! Yeah it took a little time, but the numbers should help people to see the overall light distribution. Hopefully it serves as a useful reference!
Sylstar is also very good, I run a SF2000 in a 2x2x5 and a Sylstar GL2000 I picked up direct from the supplier in another 2x2x5 and Imo it's just as capable. had some real healthy tomatoes and lots of yield running a single hydro set up in each.(oxy pot)
I just picked up their entry level 110watt light to check it out. The quality control was pretty bad but if the diodes are indeed genuine lm301b then it's very good value. I probably paid less than half the price of the spider farmer light.
What do you recommend dimming knob to be set to in flower? +Spider Farmer 4K 18 inches above canopy. My ladies are 3 week in flower and 100 percent happy and healthy. This is my first run with the SPF 4K.
I recently bought an sf2000 and they have switched to an uneven diode distribution (biased towards the edges); from pictures, they seem to have done the same to the sf4000. Can we expect more even PPFD coverage?
What do you think about BXEN-50S-11M-3C-00-0-0 as grow lights? The 50S model has (according to the datasheet) little bit better spectrum with much lower price.
I’m choosing one but to figure out which one I’ve a question: for auto-peppers 😝 20/4hrs what is the DLI to aim for? 500 ppfd x20hr are good or not? Thx
I've done a lot of research on this subject. Whether you're growing auto or photoperiod peppers, Spider Farmer is the best value for money. You cannot go wrong with them.
So my question is this. With 2 Spider Farmer 4000’s in a 4x4 tent I have what should the light be set and how high? The plants are in the flowering stage but so far the light is set at 22 inches and around 30% Brightness. There are 11 ILGM White Widow in the tent. It has a auto watering drip system and the lights come on at 5 AM and go off at 11. They were planted in 3 gallon fabric pots 24th of August. The soil is a mixture of Fox Farms Ocean forest and Happy frog and another soil with no amendments. They are mixed 1/3 each to keep the soil from being to hot for the seedlings. Until last week they did not need or receive a feeding of any kind just PH water in low 6 ranges and the PPM is only 200 from my water source. I wish I had PAR mater but do not have one to test it.
This image shows a simulation of how 2 units would appear if placed side by side at 50% dim: albopepper.com/images/SF4000x2-side-by-side-dimmed.png There's no side reflection, but already you hit almost 1000 PPFD across much of the area. Using an 18hr light cycle at an average PPFD of 1000 yields a DLI of 65. This is pushing the limits, but experienced growers have done it. If you want a lower DLI, like 45, then 700 PPFD @18hr will do the job. To hit a DLI of 45, I would be using the 2 lights at 165W each which is about 1/3 power. Distance of 18" should do the trick. Of course, the bigger question here is: Why buy 2 lights only to dim them down? Is it a lack of vertical clearance? Otherwise, I would expect a single SF4000 to do the job quite nicely, giving a faster return on investment.
@@Albopepper It’s not a lack of vertical clearance they are WW auto flowers. We really just wanted to try it out and was not concerned with return on investment. I am however fascinated with your ability to use your PAR meter and make the charts. We may use the second SF4000 in another application at some other point. I believe we left them set around 22 inches at the 30%. range. We travel so I don’t remember exactly. It’s been a week or so and will be seeing them today when I return.
@@Albopepper can you run your PAR test on 3 cannons in a 4x4 tent? www.blacksailmarket.com/meet-the-cannon Currently we have 3 running in a 4x4 tent at 200 watts each. Your ability to measure PAR is greatly appreciated and your willingness to make the charts and graphs for a stranger is beyond exceptional. Your channel deserves way more followers.
Thanks for your kind words Kevin! I checked your link and the seller doesn't show a PPFD map, nor do they state the Total PPF. But with a little math you can figure out the output. They list an efficacy of 2.0 umol/J. So multiply that by the power (332W) and the Total PPF should be 664 PPF. That is 55% of a single SF4000. If you are running 3 of those units at 200W each then the combined output should be 1200 PPF, which is the same as if you had a one SF4000 running at full wattage.
Would you say Id be ok to plug 2 sf4000s daisy chained into a surge protector in my apartment? I have a 4x8 tent that Im wanting to go from seed to harvest in. Any suggestions would be much appreciated.
The surge protector should be properly grounded. Two SF4000s should pull about 920W and 7.6 amps. As long as your surge protector can handle that, then I would expect it to be ok. Hope that helps!
I have been thinking about this video since I saw it the first time a couple months ago. I would like to know what the lowest setting on the dimmer knob one should use, without a reduced yield. I think this light is very strong, and at 100% it's just too much. What do you think? I would like to reduce my electricity consumption with this light, without my plants suffering.
Hi Ellen, could you please describe your grow setup a little? Plant type. Number of plants. Coverage area. Is it in a tent? Perhaps it could be dimmed, but these factors will impact that.
Hey Albo, really love the content. I could tell you put so much attention to detail into your videos. I have a question regarding finding the optimal distance from canopy + how hard to drive the lights. I'm currently using 5 strips of samsung SI-B8VZ91B20WW in a 4x4'. Each strip gets 100W so total of 500W(max driver can go). I can get same amount of PPFD if 12" from canopy while using 300-400watt as opposed to 20-30" at full 500W. Which would you pick and why?
I've tested the color spectrum of these Spider Farmer lights using many food plants and all of the plants did well for me. But this model is very high wattage. I'm going to use it for seedlings, but I'll be dimming it way down to 100W. I'm covering a 30" x 30" area. It doesn't make sense to purchase such a strong light and then dim it so low. You just want to grow in a small area, under the footprint of the light, is that right?
Hi great video. Looking at leds after a 2 year break. Question is I can pull 12-18 ounces from a hps light over a 4x4 table depending on the strain . Can an led pull these types of weights?...don’t worry just looked at the price for 1 in Australia 1200$....no thanks
Thanks for watching! LEDs can match or even possibly exceed growth of an HPS. It all depends on the light specs, especially the PPF output. Photons are what drive growth and a certain number of photons are needed to achieve a certain amount of plant mass. So you need to pick an LED that matches or possibly exceeds the PPF of the older HPS. This can be done, using less wattage consumption with less heat output. This video gives some tips for comparing HIDs with LEDs: ua-cam.com/video/PCaesi_M5DQ/v-deo.html .
I hope someone can help me with this? If you buy the SF 4000 and run it in a 2 * 2.5 tent, couldn't you have your light at 6" above the canopy achieve a very even light spread and use the dimming function to ensure that you don't exceed what the plant can handle?
You have the right idea. The SF4000 could be used over a much smaller area if dimmed down and placed at the appropriate height. This would work, however it's quite an investment for a light that isn't being used at full capacity. If you don't ever intend to run it at 100% then you're sorta wasting your money.
I live in Australia law's are still retarded over here. The cost of the fixture is less important than stealth. Reducing my electrical consumption footprint eases the Burdon of paranoia that comes with illegality. So I am right and can use the inverse law to my advantage. Use the larger light at approx 20 percent for veg and 50 percent for flower get even wall to wall coverage.
Hi. First of all this was a very great review. What do you think about the Lumatek Zeus 600 Pro (EU) or the Photontek X 600 Pro (North America)? Would you recommend this light for a 5x5 or for a 4x4? Lumatek aka. Photontek says 5x5 too like they did at Spiderfarmers but i'm not sure if the numbers are good enough for a 5x5. I would really appreciate your opinion.
Thanks for watching! I think you are on the right track for a 5x5 area. The higher output units can achieve higher yield for that larger area. I reviewed a similar product here: ua-cam.com/video/PCaesi_M5DQ/v-deo.html That style of light is very nice as it allows you to hang the light much closer to the plant canopy.
You should do a review of the Geekbeast Pro 630w vs SF 4000. Which would be better value for money? I understand that the 630 would need to go on a 5x5 due to ppf intensity, but wondering per $ which is the better light for maximum production?
When you compare the total light output vs the cost, both light options offer the same value. So for the smaller 4x4 tents, I would say the SF4000 is ideal (assuming you have adequate vertical clearance). And for 5x5, the Geekbeast model is a really good fit and equivalent in value (PPF/W). The smartphone app is an added bonus too.
Should my Spider Farmer sf2000 light intensity be set at 100 power, at the recommended distance or am I supposed to set the light at the recommended distance, but then dial down or up the power depending how the leaves are responding. Not sure when I should use the power at 100?
Thanks Mickey! Sorry, I don't measure lux for grow lights. Counting PAR photons is more accurate for horticulture applications, especially with custom LED spectrums.
@@Albopepper No worries, I know what you're saying I just don't have a PAR meter, haha ...I do have a lux. I was hoping to see some type of relationship between the two meters that I could use to compare to the lights I have now. I want to upgrade them but, I'm trying to decide between the spider sf 4000 and the mars fc4800. 4x4 tent. Thanks again!
Both should have similar efficacy. The SF4000 might be a slightly better value if you are looking at PPF (light output) per dollar. But the light distribution is totally different. If you don't have much vertical clearance, then you should definitely go with the FC4800. That assumes you have plants covering the entire grow area, such as a Sea of Green application. If you have plenty of height and you have a few plants grouped in the center of the tent, the SF4000 is a good option.
Hi Lokas. That's an excellent question! I've looked into the specs sheets for the LM301B and compared them to the LM301H. As it turns out, they're the same. You are correct in suspecting that it's all a marketing strategy. The LM301B are rated according to lumens measurements. The LM301H is simply measured and rated for PPF umols. However, they generate the same light!
@@Albopepper sorry USA, was thinking going by your vid that by clicking on the link provided I would save more than just ordering it directly from Amazon and not using your link. Your price is the same....
What low profile grow lights do you recommend for seed starting on tiered racks? Your product reviews seem to be for very serious indoor hobbyists that want to fruit indoors. Do you recommend the barrina leds that look like t8s?
I get the value prop for buying a light that's twice the size, but not twice the cost, but I have plants that grow at differing rates, and need to use a high light, and a low light, especially w/ seedlings. Isn't this a typical scenario?

Can the farmer sf1000 being used on cactiseed and cacti plants?
Do i need a tent (canopy)to use it?
@uncle dunk Time stamp please. Sorry, but I don't know what comment you are referring to.
@uncle dunk I didn't say not to use CO2. I was sharing a tip for estimating the PPF requirements for growers who aren't using CO2. If a grower is using CO2, then the plants would be able to utilize more photons and the PPF / PPFD / DLI levels can be higher.
At 67 years old I was a big HID guy but after replacing my two 315 CMH with a Mars fc6500 I'm sold , the difference is unbelievable and 23c , cool !

Great job as always. I sometimes refer my viewers to your channel for additional info.

Hello AlboPepper,
to be honest, I am amazed by your reviews. I searched a lot for different lamps reviews and so on. But no one delivered like you did.

I think this is one of best videos on topic of lights ...thanks
Hey gracien, just want to say goodluck to you. My community and myself included just suffered a very bad harvest failure, it have been raining non stop here and it caused a lot of flooding that damaged a lot of plants and the one that survive dies from fungal or bacterial infection, it's especially bad considering the state of the world right now so I'm wishing nothing that happened here ever happen to you
I just received my SF4000 today, glad I found your video today as I was setting it up. I am a little perplexed as to setting the distance though. My setup is a 4x4 grow tent. I have several items in there but more importantly I have a chili plant in hydro that’s flowering but wondering as too optimal distance and dimmer setting. I currently have it set to about 18in per the manual. Eventually I will move the other items out once last freeze is safely gone for my zone.
Lighting is definitely NOT an issue these days, which makes me happy.
Only issue are the internet-of-crooks.
Recently purchased the sf4000 very pleased with my investment.
Glad to hear it Shawn! Thanks for sharing your feedback on the product. :)
Great review. I recently got the SF 2000 and am really happy with it so far.
Glad you like it! Thanks for watching. :)
I have 4 SF 4000's ... they have unbelievable performance for the actual power they pull from the wall..much worth the money
i agree 100%. i even bought one for $400 and it didnt compare to the sf4000 side by side so that mixjoy without dimmer went back and got me another sf. Took me awhile to be convinced about leds but after the results of 2 sf4000's runs I am a believer.
You use 4? How many plants do you grow?
@@brianfyffe8204 the appropriate question would be, what is your square footage. All plants require different amounts of light to flourish. Example, lettuce versus "tomatos".
Nice. I am about to get my first one which will be added to my 3 x phlizon 3000s. Can’t wait to see the difference
How much energy do they pull from the wall , and how much does it show

Thanks Jon! I hope you're doing well man. Happy growing season to you too brother! :)
Very good content, as usual!
Thanks Pedro! I appreciate your positive feedback. :)
I have had an older model sf 4000 (dimmer under the drivers) so I’ve used it only at full power for a year now. I grow auto flowers and I’ve come to find out that using it as I have is just fine as long as it is never closer than 20” at any point in the grow cycle. That said, I highly recommend Spider Farmer in general, especially for the price point.
Good to know! Thanks for for sharing Mark. :)

Thank you for your wonderful Content as It is so helpful to the new grower. I just purchased a SF 2000 spider farmer light as well as a 2 x 4 grow tent for auto flowers. Hoping you can share with me your favorite light hanging height and intensity on the dimmer knob for the seedling, veg, and flower stages of the plant.
This upgrade is a long time coming friends 👍
I have burned some medicinal peppers with the sf 4000 turned down to two hundred and seventy-five ish Watts. I would have been more prone to turn the intensity back sooner if my light has this upgrade. The very next run I decided to go back to my blurple for veg and save the sf 4000 for flower. It’s a strong light for sure worth the money once I figure the height out better.
Burned in veg or flower? How close was the light?
Is it ok to keep 18 inch in veg/ seedlings but just dim it? And gradually increase at she grows?
@@tect777 Think 24" would be better
Loves the vid brother! 💕I really need to upgrade from my old budmaster LED!

Indeed. There are no LED diode factories producing grow lights in the US that I am aware of.
@@Albopepper
Thank you for responding ... we enjoy your videos.
btw... can you do a video on how much the
the Samsung/Osram LED fixtures dim over time? For all I know 2 years down the road they lose 20 percent lumen so your stuck with a brick. I want to migrate from HPS
but nobody has done long term. Do have and links to long term test?
Thank you a million,
Mack
The term to search for is "lumen maintenance." The LM301B diodes are marketed for being both highly efficient and also for having higher lumen maintenance vs many other diodes on the market. I'd love to see more info on the topic as well. I've had to dig through various product specification pages and even still, it's hard to get concrete numbers and specs for comparison. I know the Samsung diodes perform very well in this regard, but I have yet to find a complete database comparing multiple diode brands and models, let alone when compared to other tech like HIDs and fluorescents.
Awesome shirt brother
Thanks man! :)
That was very insightful, thanks!
the new 2021 sf 4000 has way better light distribution they spread the diodes in the center and packed them in tight around the corners. you can get really good par values on the edge's without getting too hot in the center. glad to see spider farmer taking feedback on their lights and making improvments.
Good to know! :)
I’ve got 2 of these mounted on light movers in tents. I am very much using them wrong, but because I know how I’m using them wrong, I’m using them “right” for what I’m doing. I’ve got one fixture per 4x8, and have some shadows as it moves all the way. But, i do think this can cover a 4x6 tent on a mover and give the maximum potential yeild the light can with relative ease.
1994 called, wants their light movers back.
Thanks for sharing the last thing I need to complete my I door growing set up this winter has been the lights so much misleading online it's hard to decide what light set up to buy
I understand Casey. I hope my videos are able to help you out a little. Thanks so much for watching!
Hypothetical question: If I make an array of ultra-high-efficiency home-lighting LEDs, like the one you show at 6:23 (say in the 120 lumen per watt category), would these be an okayish alternative for grow-lights? If I supplement the warm-white with a few "special" LEDs, say 395nm or 750nm, would it make growth meaningfully better? I'm not looking for "medicinal" plants, just kitchen-garden herbs; the ridiculously cheap home-lights (2024) are skewing the "bang for the buck" story, imo.
Very good video 👍
Thanks for watching! :D
Very nice and informative thanks a lot:)
My SF4000 only covered an actual 3'x3' area in flower, with the center being way too intense. The outlying 1'x1' area of the tent was a total waste. I replaced it with a Mars Hydro FC4500 that actually covered the 4'x4' and the difference in yield was impressive in addition to being a really good light. They nailed this design and I hope you can test and review them soon.
Thanks for sharing your experience with this model. What you're describing matches up perfectly with what I said in this video. If your center readings were too high and the outer edges were poorly lit, then your light was too close. That's the light physics of this unit. It should have been raised higher for more even coverage. I'm at Mar Hydro's site right now & I don't see anything for an FC4500. But I DO see an FC4800. That type of model is _EXCELLENT_ for even coverage at much lower hanging heights. It should be positioned totally differently than the SF4000.
I don't agree with the specs for the FC4800 though. The Par Value seems to me, to be fabricated. I don't believe this light puts out 1649 umols while drawing 480W. That would mean 3.44 umols/J. I don't believe it. And so I have difficulty trusting their listing...
@@Albopepper Sorry... I confuse the 4800 and 6500 model numbers because I have them both. As for having the SF4000 too close, there are limits to the hanging height inside of a tent due to the wire hangers so I can agree to a point... But even raising that style of light higher will only moderately raise the readings at the edges of the fixture; you simple cannot have proper intensity where there are no diodes which is why I prefer the strip style fixtures. I'm sure the Mars readings are not 100% accurate either, but what I'm seeing on my meter is more than enough for flowering even at extreme levels over the entire 4'x4' area... Which was not the case for the SF4000. Real world, it simply wasn't enough coverage for a 4'x4' growing cannabis to the results I expect.
No worries about the model number! At least I was able to figure out which one you meant. Being physically constrained by hanging height is a real issue. I'm glad you brought this up. Hopefully it will inform others who have vertical limits in their tent size. In your situation, it sounds like you made the perfect choice by switching to a system that has a broad diode layout. What was the distance that you had between the SF4000 and the plant canopy? That info might be able to help out other viewers. No CO2, right?
@@Albopepper Hanging height is a big issue with these kinds of intensity (especially without knob dimming), and this was in a full size 8'x4'x7' tent... The SF4000 was 14-16" from the majority of the canopy, so it was not especially close. I didn't see any bleaching or other signs of the light being too intense, but I could not move the light higher without discarding the wire hangers... We could really use a low profile hanger to make use of the extra foot of space. I don't run Co2 in that tent, but it does average about 600ppm+/- due to it's location inside, so I think I fared better with light stress than would otherwise happen.
Thanks for that! So planning on 18" as a minimum was good advice then. But yeah, custom hanging wires might be needed to achieve it. In my little ghetto grow chamber I had to do exactly that to conserve space. I ditched the OEM wires and used some hanging chains instead.
overwhelmed, I am looking at a 2 foot square tent, need your top 2 best lights for a small medical pot grow. 2 of the best. I appreciate your insight.

Hi Anna! Thanks so much for watching and for supporting my channel! :-)
Very good video. Thanks!
Thanks for watching! :)
Nice video with solid info! It's obvious that experienced grower's knowledge exceed the one of an average marketing department employee 😊💚🐛.
Btw. there is some benefit in using two SF2000 (or four SF1000) lights instead one SF4000. With multiple lights you can get more even spread (less hot spot).
Thanks for watching! If your growspace is rectangular then the SF2000s are certainly going to be more flexible for creating uniform coverage. In a perfectly square tent, there's less advantage to using the 2000s. Perhaps if there is very little vertical clearance then the 2000s might work out just a little better. But with a my smaller tent size recommendations, along with sufficient hanging height, the SF4000 will do rather well.
@@Albopepper Yes, you are absolutely right. Like for a 4' x 4' the SF4000 is surely the perfect fit.
Yeah i cant wait till Able get some them new LEDS
Nice stuff.
The fact that you could even get ahold of Samsung to find out the reason for price fluctuations is amazing. Gives me faith that someday I might be able to source leds from them. Hahah JK prob not. Idk if it’s because of Covid but I can’t even get the led stars, or individual diodes to reflow myself that I’m looking for. I just made one 730nm module to add to my HLG650R lights. I wanted to see if I could do it first( never even soldered until now) so I only ordered 21 triple 20mm star mcpcb for a small Slate single QB648 light. I’m trying to go 1:1 wattage wise with the 730nm to Quantum Board total( I know it’s not commonly used at all let alone at this level )
nice video thanks. really helped me understand
A1 information sir. A lot to keep in mind. Thank you.
Thanks for watching Uncle Dave! :-)
@@Albopepper I can learn new tricks...I can learn new tricks...I can learn new tricks....with your help anyway.
Another great review and appreciated. Nice job! Might have been an improvement for Spider Farmer to space the four boards out, instead of clustering them for better corner coverage and more even lighting.
Good observation Matt! Yes, spacing out each board would provide more even coverage. That would be most crucial for growers who are limited on vertical space.
Great thing about led is you can leave them on 24/7 which helps to reduce maturity time of plants
Some types of plants can do ok under 24hr light cycles. But not all plant. Many of the high light flowering plants require a 12/12 cycle to complete their reproductive phase. Something to keep in mind.
Great and honest review as always. I do wish Spider Farmer would come out with linear/rail version (e.g 3"x 4' or 2') that would allow us to change the configuration around for something other than a square tent. Until then I'll just have to keep building my own
I agree! That would be pretty nice. :)
so it makes no sense to buy the se 7000 without co2? thx for the videos!

hokey smokes! that was 169 ppfd readings per chart. so... 845 readings for the 5 charts??? Well done!!!
LOL, thanks! Yeah it took a little time, but the numbers should help people to see the overall light distribution. Hopefully it serves as a useful reference!
The sf2000’s have the dimmer knob now too so you don’t have to use any tools
True, true. It's much easier now! :)
@@Albopepper i honstly didn’t know what it was until I watched this video so thank you
Sylstar is also very good, I run a SF2000 in a 2x2x5 and a Sylstar GL2000 I picked up direct from the supplier in another 2x2x5 and Imo it's just as capable. had some real healthy tomatoes and lots of yield running a single hydro set up in each.(oxy pot)
I just picked up their entry level 110watt light to check it out. The quality control was pretty bad but if the diodes are indeed genuine lm301b then it's very good value. I probably paid less than half the price of the spider farmer light.
What do you recommend dimming knob to be set to in flower?
+Spider Farmer 4K 18 inches above canopy.
My ladies are 3 week in flower and 100 percent happy and healthy. This is my first run with the SPF 4K.
I recently bought an sf2000 and they have switched to an uneven diode distribution (biased towards the edges); from pictures, they seem to have done the same to the sf4000. Can we expect more even PPFD coverage?
What do you think about BXEN-50S-11M-3C-00-0-0 as grow lights? The 50S model has (according to the datasheet) little bit better spectrum with much lower price.
I’m choosing one but to figure out which one I’ve a question: for auto-peppers 😝 20/4hrs what is the DLI to aim for? 500 ppfd x20hr are good or not? Thx
I've done a lot of research on this subject. Whether you're growing auto or photoperiod peppers, Spider Farmer is the best value for money. You cannot go wrong with them.
How do I get my hands on the newer model sp1000?
When should you use that dimmer and how much should you dim when you use it?
Amazing video tnx
Thanks so much for watching! :)
I just want to see a side by side comparison of your light with the "equal" hps light growing weed. That will show if it is worth the cost.
It would probably outperform a 600w HPS while staying nice and cool which is not only safer, it reduces power consumption to almost 1/3 of the HPS
So my question is this. With 2 Spider Farmer 4000’s in a 4x4 tent I have what should the light be set and how high?
The plants are in the flowering stage but so far the light is set at 22 inches and around 30% Brightness. There are 11 ILGM White Widow in the tent. It has a auto watering drip system and the lights come on at 5 AM and go off at 11. They were planted in 3 gallon fabric pots 24th of August. The soil is a mixture of Fox Farms Ocean forest and Happy frog and another soil with no amendments. They are mixed 1/3 each to keep the soil from being to hot for the seedlings. Until last week they did not need or receive a feeding of any kind just PH water in low 6 ranges and the PPM is only 200 from my water source. I wish I had PAR mater but do not have one to test it.
The WW in this tent are autoflowers FYI. They were given a bloom granular feeding last week and they seems to like it so far it’s only been 4-5 days.
This image shows a simulation of how 2 units would appear if placed side by side at 50% dim:
albopepper.com/images/SF4000x2-side-by-side-dimmed.png
There's no side reflection, but already you hit almost 1000 PPFD across much of the area. Using an 18hr light cycle at an average PPFD of 1000 yields a DLI of 65. This is pushing the limits, but experienced growers have done it. If you want a lower DLI, like 45, then 700 PPFD @18hr will do the job.
To hit a DLI of 45, I would be using the 2 lights at 165W each which is about 1/3 power. Distance of 18" should do the trick.
Of course, the bigger question here is: Why buy 2 lights only to dim them down? Is it a lack of vertical clearance? Otherwise, I would expect a single SF4000 to do the job quite nicely, giving a faster return on investment.
@@Albopepper It’s not a lack of vertical clearance they are WW auto flowers. We really just wanted to try it out and was not concerned with return on investment. I am however fascinated with your ability to use your PAR meter and make the charts. We may use the second SF4000 in another application at some other point.
I believe we left them set around 22 inches at the 30%. range. We travel so I don’t remember exactly. It’s been a week or so and will be seeing them today when I return.
@@Albopepper can you run your PAR test on 3 cannons in a 4x4 tent?
www.blacksailmarket.com/meet-the-cannon
Currently we have 3 running in a 4x4 tent at 200 watts each. Your ability to measure PAR is greatly appreciated and your willingness to make the charts and graphs for a stranger
is beyond exceptional. Your channel deserves way more followers.
Thanks for your kind words Kevin! I checked your link and the seller doesn't show a PPFD map, nor do they state the Total PPF. But with a little math you can figure out the output. They list an efficacy of 2.0 umol/J. So multiply that by the power (332W) and the Total PPF should be 664 PPF. That is 55% of a single SF4000. If you are running 3 of those units at 200W each then the combined output should be 1200 PPF, which is the same as if you had a one SF4000 running at full wattage.
Would you say Id be ok to plug 2 sf4000s daisy chained into a surge protector in my apartment? I have a 4x8 tent that Im wanting to go from seed to harvest in. Any suggestions would be much appreciated.
The surge protector should be properly grounded. Two SF4000s should pull about 920W and 7.6 amps. As long as your surge protector can handle that, then I would expect it to be ok. Hope that helps!
I have been thinking about this video since I saw it the first time a couple months ago. I would like to know what the lowest setting on the dimmer knob one should use, without a reduced yield. I think this light is very strong, and at 100% it's just too much. What do you think? I would like to reduce my electricity consumption with this light, without my plants suffering.
Hi Ellen, could you please describe your grow setup a little? Plant type. Number of plants. Coverage area. Is it in a tent? Perhaps it could be dimmed, but these factors will impact that.
@@Albopepper
Yes, absolutely. I have a 4x4x6 tent. SF4000. I am planting seeds today. Considering 4 or 5. Cannabis. Autoflowers.
@@Albopepper I really appreciate you taking the time to answer my question. I am so glad I found your page. Great content!!
Mint vid
Does anything compete with this light at its current price ($490)?? And does it compare to anything in the $700-800 range?
Hey Albo, really love the content. I could tell you put so much attention to detail into your videos. I have a question regarding finding the optimal distance from canopy + how hard to drive the lights.
I'm currently using 5 strips of samsung SI-B8VZ91B20WW
in a 4x4'. Each strip gets 100W so total of 500W(max driver can go). I can get same amount of PPFD if 12" from canopy while using 300-400watt as opposed to 20-30" at full 500W. Which would you pick and why?
Are there any food plants that would do well around the main light footprints also under 12-12 lighting?
I've tested the color spectrum of these Spider Farmer lights using many food plants and all of the plants did well for me. But this model is very high wattage. I'm going to use it for seedlings, but I'll be dimming it way down to 100W. I'm covering a 30" x 30" area. It doesn't make sense to purchase such a strong light and then dim it so low. You just want to grow in a small area, under the footprint of the light, is that right?
Hi great video. Looking at leds after a 2 year break. Question is I can pull 12-18 ounces from a hps light over a 4x4 table depending on the strain . Can an led pull these types of weights?...don’t worry just looked at the price for 1 in Australia 1200$....no thanks
Thanks for watching! LEDs can match or even possibly exceed growth of an HPS. It all depends on the light specs, especially the PPF output. Photons are what drive growth and a certain number of photons are needed to achieve a certain amount of plant mass. So you need to pick an LED that matches or possibly exceeds the PPF of the older HPS. This can be done, using less wattage consumption with less heat output. This video gives some tips for comparing HIDs with LEDs: ua-cam.com/video/PCaesi_M5DQ/v-deo.html .
@@Albopepper thank you heeps for the reply. More research is definitely needed.
I hope someone can help me with this? If you buy the SF 4000 and run it in a 2 * 2.5 tent, couldn't you have your light at 6" above the canopy achieve a very even light spread and use the dimming function to ensure that you don't exceed what the plant can handle?
You have the right idea. The SF4000 could be used over a much smaller area if dimmed down and placed at the appropriate height. This would work, however it's quite an investment for a light that isn't being used at full capacity. If you don't ever intend to run it at 100% then you're sorta wasting your money.
I live in Australia law's are still retarded over here. The cost of the fixture is less important than stealth. Reducing my electrical consumption footprint eases the Burdon of paranoia that comes with illegality.
So I am right and can use the inverse law to my advantage. Use the larger light at approx 20 percent for veg and 50 percent for flower get even wall to wall coverage.
Hi. First of all this was a very great review. What do you think about the Lumatek Zeus 600 Pro (EU) or the Photontek X 600 Pro (North America)? Would you recommend this light for a 5x5 or for a 4x4? Lumatek aka. Photontek says 5x5 too like they did at Spiderfarmers but i'm not sure if the numbers are good enough for a 5x5. I would really appreciate your opinion.
Thanks for watching! I think you are on the right track for a 5x5 area. The higher output units can achieve higher yield for that larger area. I reviewed a similar product here: ua-cam.com/video/PCaesi_M5DQ/v-deo.html That style of light is very nice as it allows you to hang the light much closer to the plant canopy.
I brought 2 was working great. For some reason it's been flickering non stop...any solutions?
albo;great camera@
You should do a review of the Geekbeast Pro 630w vs SF 4000. Which would be better value for money? I understand that the 630 would need to go on a 5x5 due to ppf intensity, but wondering per $ which is the better light for maximum production?
When you compare the total light output vs the cost, both light options offer the same value. So for the smaller 4x4 tents, I would say the SF4000 is ideal (assuming you have adequate vertical clearance). And for 5x5, the Geekbeast model is a really good fit and equivalent in value (PPF/W). The smartphone app is an added bonus too.
Is the ballast on the SF4000 removable so that it can be kept outside of the grow tent to reduce heat inside the tent?
Should my Spider Farmer sf2000 light intensity be set at 100 power, at the recommended distance or am I supposed to set the light at the recommended distance, but then dial down or up the power depending how the leaves are responding. Not sure when I should use the power at 100?
Very like your video
Thank-you very much for watching!
@@Albopepper I also plant the production of such a lamp, if the lower prices, better service, consider adding a supplier Well
So nice to see Luigi is into indoor gardening.
Then how many of them i need to cover 10ft by 6ft tent ????
For that size tent, I would probably try 2 x SF4000s + 4 x SF2000s. Like this: albopepper.com/6x10.pdf
I gone split my grow space in two sides to have access to my plants , 6 on side. I think to buy two 4000 with four 2000.
Great video...will a lux meter work on these? Do you have any lux numbers?
Thanks Mickey! Sorry, I don't measure lux for grow lights. Counting PAR photons is more accurate for horticulture applications, especially with custom LED spectrums.
@@Albopepper No worries, I know what you're saying I just don't have a PAR meter, haha ...I do have a lux. I was hoping to see some type of relationship between the two meters that I could use to compare to the lights I have now. I want to upgrade them but, I'm trying to decide between the spider sf 4000 and the mars fc4800. 4x4 tent. Thanks again!
Both should have similar efficacy. The SF4000 might be a slightly better value if you are looking at PPF (light output) per dollar. But the light distribution is totally different. If you don't have much vertical clearance, then you should definitely go with the FC4800. That assumes you have plants covering the entire grow area, such as a Sea of Green application. If you have plenty of height and you have a few plants grouped in the center of the tent, the SF4000 is a good option.
Hey Al what do you think about the new Samsung Lm301h series? Are they better or is it just a marketing strategy?
Hi Lokas. That's an excellent question! I've looked into the specs sheets for the LM301B and compared them to the LM301H. As it turns out, they're the same. You are correct in suspecting that it's all a marketing strategy. The LM301B are rated according to lumens measurements. The LM301H is simply measured and rated for PPF umols. However, they generate the same light!
What if I have 20 of these, would I be able to daisy chain all of them just like that?
The product listing indicates that up to 10 units can be daisy chained to a single controller.
How about power source??
Can you connect more than one together for power or does each light require it to be plugged into a outlet for power?
Each light requires its own individual power connection.
That sucks..thought i seen a "T" where the main attaches to the ballast and could run more than one ballast off one main cord

I get the value prop for buying a light that's twice the size, but not twice the cost, but I have plants that grow at differing rates, and need to use a high light, and a low light, especially w/ seedlings. Isn't this a typical scenario?
Some of the plants might also have different photo-period requirements. If you need a separate veg light, then get whatever works for you.
Are these LED lights applicable outdoor? Please reply, this might be helpful to our thesis. Thamk you
These are not 100% weather proof.
Would 4 of them cover a 10x10 grow tent by chance?
Try 6.
