PRODUCT HIGHLIGHTS
==================
I measured the light levels of Spider Farmer's 200 watt SF-2000 grow light. I took a variety of PPFD readings using my Apogee quantum light sensor. This video shows my readings at 2 different heights and 7 coverage areas. Two readings were without side reflection. The others used reflective sidewalls.
When comparing the light levels of any two grow lights, it's better to use PPFD measurements. Measuring lux or lumens is less reliable, especially with custom light spectrums. But simply showing a center PPFD reading isn't enough! How much area can the light cover? How evenly is the light distributed?
Longer LED panels can spread the diodes out over a longer area, allowing you to get some pretty consistent light coverage. But you still need to see the light map over a given area at a set distance. And it's important to account for side reflection and the role that it plays in boosting photon penetration.
Of course, you also need to consider the needs of your plants. Are they young, still growing in their vegetative state? Or are they mature, producing blooms, buds or fruit? Different stages require different DLI (Daily Light Integral) levels. And some plants also require shorter photoperiods, which in turn, increases light demands.
DIMMING OPTION: I like SF-2000 specs, but it's overpowered for my small growing area. Used for seedlings & vegetative growth, my grow chamber has a top & bottom section. In the bottom, I've continued to use a 2 foot T5 because of limited vertical clearance. But now I can finally retire my outdated, inefficient fluorescent! I dimmed the SF-2000 to 75w. It pumps out three times as much light as the old T5 without using any extra power! The revised models now have a proper, external dimming knob which makes this even easier!
Watch my video on the 4000 for a demonstration:
• Super Bright LED Grow ...
FINAL THOUGHTS: I liked my SF-1000, but I like the SF-2000 even more. It packs more diodes onto each board. That means fewer watts per diode. I would expect that to translate into longer life. The PPFD values are impressive. Spider Farmer also offers a 400 watt unit (SF-4000). However, depending on the price, it might be better to just buy two SF-2000s rather than a single SF-4000. You would get much more flexibility in how the light can be distributed over the plant canopy. So run the numbers & see which is better for you!

Could you do me a favour with the sf2000 and position it around 40cm from the sensor in a 100 cmx 50cm space and see what I'd need to dim to in order to get 300 ppfd? I'm growing cacti and succulents which could take 1000umol but I don't fancy paying that electricity bill ha.
How well do you think the SF2000 would work with super hot peppers that require ridiculous amounts of light
May I ask your opinion on the tolys 1000 watt full spec led grow light? I'd love to hear your thoughts.
@@globeheadgardener It's not 1000 watts, so I have no respect for the seller. Also, it's fairly blurple in color, which I really don't like.
@@Albopepper what would you recommend for a 6 foot by 4 foot grow space sir?
I get frustrated by the random musings of well-meaning guys that probably know less than I do. Equally frustrating are the tech-heads that are so far past my beginner level that the topic seems simply impenetrable. The info you provide here is clear and understandable. I'm sure I would get even more out of it were my knowledge base to be a bit stronger. The mark of a gifted teacher is his or her ability to meet a wide range of learners where they are then to provide useful info that will increase knowledge of the topic for everyone. You, sir, receive an A+ for your efforts!
Thank you so much for providing these excellent videos on a topic that seemed so daunting but now seems like I will be able to make an educated purchase.
I believe this is probably the light that best suits my needs. Efficiency and the cost of operating the light are very important to me. I will be growing only 2 or 3 mari-tomatoes. Using the dimensions provided here, I believe I can use reflective siding to configure a small space in the closet I have dedicated for this purpose.
Thanks again!
Thanks Stephen! I greatly appreciate your kind words and your support on my channel. I'm glad this info is able to help you out. Also, thanks for sharing the details of your personal grow project. I hope it all works out very well for you! :-D
This is why I link Albo and other people’s videos to people instead of explaining things myself. I am bad at not being wordy when explaining.
@@juliankirby9880 Man I got the same damn problem and it's so frustrating some times when you want to say something but cant find the words to say it! Lol! Damn the dumb people that are so wordy they make themselves sound smart! Lol
Albo you are my favorite UA-camr. Always a pleasant surprise to see your videos in my feed!
I actually purchased the SF 2000 for my marimatoes after watching Albo's review of the SF1000 and have been thrilled with the results so far after using it briefly in two grow areas. I started with the light dimmed down over six clones that I had recently transplanted into solo cups with the light about 8 inches above. They grew stocky, leafy and green with no signs of stretching or light burn. Next when the power went out on my 2 foot 4 bulb HP T5 with AgroLED tubes, I moved this light into full power position over two plants in week two of flower in my 4x4 tent. It is currently about 12 inches over the plants with supplemental 2 foot, 2 bulb T5s with AgroLED bulbs on the far sides (each plant is trained wide and flat so together they easily cover a 4x3 area.) Now in week 4 of flower I can see a difference in the size and density of the flowers with very little stretching compared with my last grow. Power usage is spectacular. With all lights and 4" fan on low power, I'm only pulling 320 watts and my biggest concern is potential light burn. Heat is a non-issue. My basement consistently stays at 65 degrees and in the tent with all lights blazing it gets up to 74 during the day when the lights are on.
I plan to eventually get an SF 4000 to cover the entire grow area and then move the SF 2000 into a veg room. My T5 will probably be used strictly for clones and seedlings in March when I start plants for my outdoor garden.
That's awesome Dave! Thanks for sharing your detailed experience with this system. :-)
Thanks for such a detailed description of how you are using the light. I feel pretty confident in purchasing this light now.
Best review I’ve ever watched of any grow light, bar NONE!! Thank you SO much. Only reason I stopped by was I’m about to purchase the SF 2000 and fell in love with your review style & technical knowledge! Thank you!!!
Last year, I bought my Spider Farmer SF-1000 because of YOUR video! Knowing literally nothing about growing plants under artificial light my orchids are now in bloom like never before and I'm getting new roots, spikes, and leaves across all of them like crazy! I've even got geraniums blooming indoors as an experiment - in winter!!
Learned more in 2 of your video's on lights than from all other sources. New subscriber. :)
I have (2) SF 1000’s. This video is spot on. I have a 4x4 tent and currently use the (2) 1000’s with a 600 hps. Planning to swap the hps for an SF 2000 or 4000 next and leave HID behind for good. Great review!
Thanks for watching! :)
Just ordered one from Amazon using your link. Thanks for the Discount Code, it worked. Stopped using my HID lights as they drove the electric bill up quite a bit.
Thx for the info ! I bought the sf-2000 and never had reliable ppfd data to adjust lamp height. I love my sf-2000 even more now 😍. Thx again.
Solid review. I especially like the coverage and PAR changes information as the area and hang height changes. Should help people visualize things better. Only thing better is if they sent me lights to review.
*Great video. So many people out their are so focused on the power draw and what the electrical bill is going to be they neglect the fact that with a light that has the right intensity for flower that uses more electric will also give them more yeild which will always more than compensate for the increased electricity costs over the 3-3½months of their grow cycle from seed/clone to harvest. *
*I wish alot more people saw this video and stopped wasting their money on lights only really good enough to veg as they don't offer the intensity over a decent coverage area for flowering*

Hi from Canada! I'm researching for a new light to grow medicinal tomatoes for my husband. I just starting the seedlings. 8 will be moved outside and 4 will be kept inside. A bit of an experiment! Last year I started 6 inside and moved them all out @ 8-10 wks, so the 1 light was enough to start 6 seedlings. My hubby said the tomatoes were delicious. I am going to try adding tomatoes to some recipes so I am growing extra. The tech changes so quickly it is hard to keep up! Who wants to spend $$$ for a POS light? So thanks for your reviews. They are to the point and easy to follow. As a hobby gardener I don't need tons of excruciatingly detailed techno babble. I still have more research but you have given me a starting point I hope all is well down there, keep eating healthy! Thank you again. ......edit...... still looking but am leaning toward TWO of the SF2000 rather than one SF4000. That should cover my 4 indoor plants from start to finish. Now I have to find mylar to drape around the girls!! A lot of Canadians have taken up gardening since last year! Such a rewarding and money saving hobby. Those medicinal tomatoes are pricey. I also grow other things.....peppers, carrots, garlic, zucchini, kale.......but my tomatoes seem to be the favourite! edit again.......Subscribed!!!! Learning lots about indoor tomato growing. YOU are awesome! I mean it, keep up the good work, don't friggin stop!
I'm so happy I discovered your channel Al!!! Interestly enough, I purchased the SF-2000 AFTER I started following you recently, but BEFORE I saw this video! Which makes me ecstatic about my purchase after a decent amount of research, including so many of your videos!!! I got this for a 36" x 18" tent. It has been about 10 years and so much has changed since then as the "best of the best" back then was cfl, and the infancy of blurple lights. I look forward to seeing some plump juicy tomatoes here in a few months!! I appreciate you and your passion. Look forward to more content!
Super informative and content rich update on the SF2000. Congrats on making a watch (and watch repeatedly) video that is extremely helpful!
Thanks so much Matt! I appreciate your support. :-D
Just so everyone knows the SF2000 now has an analog dimming knob mounted on the board next to the Meanwell driver. I emailed Spider Farmer confused and they told me the product had been upgraded and to enjoy. I have nothing to do with this company but they haven't updated the specifications anywhere these are sold so I'm doing it for them here. Hopefully this info helps(your welcome spider farmer). I wouldn't take the time if i didn't like this product. Really appreciate all the useful info AlboPepper. A good, seemingly unbiased opinion/review is a rare thing nowadays.
Side note: Their customer service has been great. Very responsive with basic questions I've had. This is a BIG deal for me.
Good to know! Thanks Sam!!!
This is literally exactly what I was looking for but couldnt find for hours
Rudy Melo ya, me too.... I found this video several months ago, but couldn’t remember where I found it. An hour later, and here I finally am!
You my man, are THE MAN! Gonna peruse and see what else you’ve got good!
Welcome to my channel! Thanks for watching. I appreciate your support! :)
Where have you been all my life?? thanks for the high quality videos
Outstanding summary of grow lights. And under 11 minutes. Amazing. Subscribed.
Welcome to my channel! I appreciate your support. :-D
It’s rare when I take the time to subscribe or write a comment for you my friend are awesome I love how thorough you are and how clear and precise you are I will definitely be searching of all your pets videos in the hopes of sucking up some of your knowledge great job bubba
I am so happy I found your channel. Thank you for not being stoned, burned out, and for having your shit together before you speak. Seriously man, you gained a fan. Grateful
Your Reviews are the best!
Rich, informative yet clear and simple, great as always.
Miss your other channel my man.
Great content on grow lights communicated in a way that makes sense. Thank you sir!
great review. i am using both the sp 1000 and sp 2000 ,, i am a satisfied customer..grow in peace
Thanks i bought a sf4000 a couple weeks ago and. Love it.
I had to dim my lights to grow lettuce because the plants were showing center leaf tip burn, and were not growing upwards. I also raised them a bit, now the lettuce is higher and totally green! 'Weeds' love light, lettuce doesn't!
I have a 40"x 40" x 80" tent and am using an SF-2000. Am in the 3rd wk. of flower with 2 Glues and 1 Wh. Widow. Just now getting quarter size buds. They look great but in retrospect I think I should have gotten the 4' x 4'tent. I did not think an SF=2000 would light a 4' x 4'. Anyway I really like my light and the gentleman is fantastic on his videos and seems very well informed.The reason I can say this is I'm 70 and watched a whole lot of crap information.Thanks a bunch!
I have both an SF-4000 and an HLG 550 V2 RSpec. They each light up a 5x5 tent, and are both very impressive lights! I want to run a 4 plant crop of autos in each tent to compare the results.
Hey man how did it work out for ya. Hope all is well.
Another WOW! video. Thank you for all the time, knowledge, and thought you put into your tutorials.
Thanks for taking time to watch Michael!
Thank you. I wish you would review the 2000 series against each other from MaxsiSun, Spider Farmer and Mars Hydro, rather like you did with the 1000 series. It's confusing their have the same basic label, they all cost about the same price, but the MaxsiSun PPE says only 2.1 (lower than the others), and the wattage is diff with each of the products, so non-tech folks like me wonder which is better (I have a small room 6x6x8h' room area, not a tent, for my plants). Thank you so much for the clear and concise information you provide in your videos, I've watched many of them.
Thanks for the good info bud. Your reviews are very helpful and easy to understand.
I appreciate your positive feedback! :-D
Great videos very entertaining but most important very honest and helpful to our future gardeneers 👍👍
I found the Greatful Grower hiding in plain sight! Thanks for your content brother! Found a new channel to follow :)
Dr. Rob really? I would have never known ive been wishing he would make more videos haha
I miss that guy man 😆
Hope he's doing well, miss his work 🙏🏽
Mari-tomato lmao
Yet another great post from you with awesome data analysis! you are a great communicator and cover some complex topics at an understandable level. Thank you for creating your channel, super helpful
Great content thank you, explained very clearly and easy to understand. Top work 👍🏻
I bought the 2000 model based mostly.on this video. Thanks for your research it's hard to find real info out there. Been using a few blurple LEDs but I think this seems better
Now thats a light Review dammmmm, GOOD JOB!
Very good work on this!
Thanks for your positive feedback! :-D
I'm getting the 2000 model thanks for the review.
Thanks for watching! I hope you like it. I love mine so far! :)
this was an amazing review ,thxs a lot for such a good work & production , cheers from argentina !
Lol once again you taught me some new tricks lol! :) my tamatoes have been getting alil light burn 3x2 feet closet i took apart amd reasembled into a a 4x2 for my SF2000 was giving me some light burn at 20" i raised the light to 24 inches then the claw stopped. But the leaves didn move upwards towards the light so i moved it up to 26 then to 28...not realizing ive got the light hanging in centre off a 3x3 space and not a 4x2 space so i centred it now to 4x2 and lowed the light to 24" after watching your doci lol thanks Doctor Tamato!:) Lol hope you dont mind me calling you that and really to appreciate your wisdom!😁
I love that you know what you are talking about :)
I'm new to growing and just got a pair of super hot pepper plants, a ghost pepper and a trinidad scorpion pepper, and I was nervous about how I would care for these things in a suburb with vast shady trees. I'm still nervous but I feel reassured that with hard data from this channel I'll have the best possible chance.
That was so good, I downloaded it to my hard drive. Thank you sir. Now I am hungry for a "tomato sandwich".
LOL! Thanks for watching Uncle Dave! :-D
I just received a new SF-2000. I made a mounting bracket (angle aluminum) for the driver so I could mount it sideways. I thought that would help with heat dissipation as well as making the adjustment screw easily accessible. I found that the lowest watts it would read was 105 (in the counter-clockwise position), and 317 watts turned all the way up!
I think it should be more strongly emphasized to newbies that creeping up on the needed power is better than finding out the hard way that changing from one light source to another (even one with less power) can really piss plants off. Some people are very attached to their peppers ;)
EDIT to add that the watt reading was 205 at 120 volts, when tested straight out of the box.
That bracket was a great idea! Thanks for sharing your feedback! :-)
I agree with you about the two lights
very thorough! great video :) Keep em comin
Thanks for watching Jim! :-D
Your videos are absolutely amazing!!!
Thank-you! And thanks for watching! :)
Really smart informative video may have to watch many times and share with others.
I had no idea how to dim a spider quantam board until now, thanks mate
Absolutely love this channel, wish I found it sooner. Mari-tomatoes killed me. Fair play. Liked shared and Subscribed.
;-) Welcome to my channel!
Good vid! Was kinda hesitant to watch thought itd b like every other light test video but since I have a spider farmer I thought I'd watch n it was actually e very good informational video n very interesting as well! I lime how you covered all the different lights and at different heights and it gave me a much better idea where to hang n how to maximize my spider farmer for my mari-tomatos!!! Lol!!👍🤣😂🤣💯
Got to love those fresh tomatoes! I seem to have the best clones, with white LEDs vegetables. I run 600watt HPS plus LEDs and straight led red spot lights. Works great . I think a lot of tomatoes were selected under HP. Have been running same kinds for several years. PEACE AND LOVE
Listen, you have probably heard this before but....
You have really kind eyes. :)
After hours of research your both funny and very informational video finally got me to a poin where i know which FREAKIN LAMP OUT OF THOUSANDS i am going to buy/ need beeing a total noob in this wholw "tomotoes" diy buiss i have made a lot of mistakes in the past and wont do in the future
excellent two-part review. Thank you
Learned so much from this guys videos thanks for all you do it saved me so much thinking research and just money from watching your videos thanks so much 🤟👍
From start to finish that was freagen AWESOME!
Thanks so much for watching! :-D
@@Albopepper lmao i love learning and that was very informative lol took it all in like adry spunge...lol plus 17days from now my SF2000 WILL BE HOME IM SO SUPER STOCKED!!! Lol happy growing!:)
Awesome! :-D
How low can the sf2000 be dimmed down to? You've done a fantastic job with this video by the way! I am one of the few people interested in an sf2000 to dim down as I'll be running it around 36cm from succulent plants/ seedlings in a 50cm X 100cm X 50cm tent
Do you think the sf2000 is more efficient than the 1000w due to the lower wattage draw from each individual diode?
Thanks for watching! I was able to dim the SF-2000 down to at least 50w. I might have been able to go further, but I didn't push the limits. Not sure if the SF-2000 has a higher efficacy rating than the SF-1000. But I was really quite impressed with the SF-2000, above and beyond the SF-1000. And certainly for the lifespan aspect, I just like the idea of using more diodes at a lower wattage per diode.
Great information. Gets one thinking. Best guess if a SF 4000 could flower a 4x4 tent with medicinal tomatoes?
Yes, my SF4000 is flower in a 5'x5' tent with medicinal tomatoes lol
Yes, it would be perfect for that.
Very helpful and fun style you've got here. Thank you. Subscribing now.
Thanks once again for the info, I will be back next time and click the page in amazon for the lights right now dont have enough budget, thanks. God bless
Thanks so much for your support! :-D
This guy has the goods.
It's all about the ppfd baby.
You said it!
Awesome video. Thank you.
Only the best info! thanks :D
Wish everyone went into detail like this with any and all reviews. Subscribing ! 🙌
Super review Bro cheers happy week
Thanks for watching! :)
Medicinal Tomatoes Are The Best.
what are those 🤓🤩
So many strains
I am so glad that you are serious in your experiments with height and wattage, etc. I will study this video mush more closely and jot down your measurements. I want to build a reflective structure like yours. Can you share some info on the what and how-tos? I will check to see if you already have a video on this. Thank you.
No disrespect....
I have been watching your video tapes for AGES (SEGA)....
you always remind me of Super Mario The Plant Guy with Green Fingers and some knowledge of electricity. But hold on.... Wait a minute Super Mario is a Plumber.... Dwc, Ebb and Flow (Flood and Drain) NFT, Dwc .
The list goes on...
Brilliant video Tape....
All the way from the UK and 😊
Does dimming the light affect the longevity of the diodes? You could ponder the lower the wattage drawn and the lower the temperatures would extend the life of the light.
That sounds pretty logical to me. Lower power = lower temps = longer life.
These look roughly like the HLGs. You could cook a steak on the back of the aluminum QB housings. So in spite of the great light output per watt, my concern would be how do these things operate in an enclosed area heat wise and how much cooling effort is required?
Great videos btw. I watched your raised sip bed tutorial and subscribed. You are a great teacher.
I had the same concern. I have 2 sf2000 in a 4x4 & love them in regards to heat. The temp in my tent dropped 4-6 degrees compared to when I had 2 ViparSpectra 600s. Definitely couldn't cook a steak on these. I don't, but you could run a fan blowing on the drivers if your ambient room temp is high to begin with.
Now there's some power!
Indeed! :-)
Thank you for all the great videos! I just started growing all my veggies from seeds last year. I had an inexpensive light, but it only covered a small area. I'm trying to find the best light, that will cover a four foot area- growing tomatoes, kale, pumpkin, cucumber, watermelon- the normal garden varieties. What light would you suggest? Thank you!
This light is a whole lot better then tgose cheap blurple lights that are all over. I'm glad to know I'm not the only one here using a grow light for actual vegetables!
I keep telling people to look at the par mapping of a newer 600w LED, with samsung or similar diode in comparison to a 1000w HPS. The par map says all.
Hustle Bones
but why they don't listen? ^^
@@s.cookie1136 what do you both mean??
A light mover is a great option for LED.
Thank you
the Parr meter on my phone. The App. Works pretty good.
Hi man, always the best explanations! Not enough info out there about DLI requirements of AUTOFLOWERING tomatos 🍅 🤣.
If they go 20/4 all their life long, what are perfect ppfd values and DLI? Please help. Thx
Mari-tomatoes lmao subscribed, keep it up
Welcome to my channel! I appreciate your support. :-D
Im so glad I stumbled upon this channel. My question is in regards to photosynthetic rates at higher umols. In regards to your "Mari-tomatos", isnt there a max amount of umols that a plant can use for photosynthesis? I was under the impression that at certain temps, c02, and air flow, photosynthesis kind of maxes our around 600umols? Is that at specific spectrums, intensity, distance , etc? Im not super familiar with ratings in PPFD. Thanks for your content!
So you’re saying a 200 watt sf2000 is equivalent to a 400 watt hid? I was under the impression for some reason that led watts were below that of hid. IE: a 400 watt hps and a 400watt led = the hps remaining true, while the led is playing catch up. Or maybe it’s the info people are sharing on here that is wrong which is why many people get confused easily when it comes to lights.
I’m in the process of deciding what type of light I want. I know I can’t go wrong with hid, but I heard they can be a bit noisy and cause extreme heat, which means you need more gadgets and tools and materials to make the perfect temp for your grow space. With LED I noticed mixed things from a bunch of people. But I have noticed growers with nice yields, but I feel hid produce bigger yields, they’re just more cost effective. Is this true or no? I’m a beginner I suppose. I’ve grown in the past and am finally at a stage where I want to get back into growing medical tomatoes again.
Assuming you have an HPS (single-ended) with an efficacy of about 1.34 (603 PPF @450W), the SF-2000 should have nearly the same light output (527 PPF). It is slightly less, but you get uni-directional light, so less photons are wasted. Thus, the SF-2000 should be an acceptable replacement for that HPS.
For bigger yields, you need more photons. HPS is not the best. It's just that some growers select underpowered LEDs and then they think HPS is so much better. Not really. They simply weren't supplying the same amount of photons to the plants. A highly efficient 300W LED (actual power draw) would outperform a single-ended 400W HPS.
any suggestions on a cheap led to start vegetables for my garden meaning Tomatoes,Peppers,cauliflower,broccoli and like vegetables and flowers my area is 4.5 x 6.5? Very informative videos.
This is the best!
@ 8:00 ...you discovered the big secret ....led (chips) run more efficiently when under powered (dimmed) ... you can get 30% more light per Watt of electricity , and also the leds will last much longer .... The biggest cost is your electricity bill , light manufacturers don't care about that ... they cut costs , use less leds and drive them at max power ... When growers understand this there will be a new revolution in grow lights
oz93666 so what light would u recommend ?
Awesome reviews! I’m growing some indoor tropical houseplants and was wondering which would you choose to use for a grow light, the SF2000 vs SF600? Most of my plants need bright indirect light, some just need moderate light. Thanks in advance for your help!
Thanks for watching! The SF2000 would cover a much broader area from a higher hanging height. So if your plants are large and you have several of them, it would be a better option. Especially since it can be dimmed when required, unlike the SF600.
@@Albopepper Thank you for your input! 🌿🌿🌿
@@Albopepper ah, I have another question. Would you choose the SF2000 over the Maxsisun or viparspectra (are there any comparable - possibly more affordable?)
Thank you for the review....you seemed to digress and lost me at 5;23 though 3rd time I.assumed that all that was said was lower lintensity for greens if not looking to fruit, and manipulating the hight for wider coverage. New to lights and dont get all the tech specs bunt got what i needed.
Was wondering if I can use plant grow bulb instead of a regular one in living room. Not necessary to grow but I got plants in here. Will this light be efficient to go about with daily things in my living room during the winter time? I do not need a lot and strong light though and perhaps plant would benefit a bit too.
Excellent revew.. Id would be good to compare this light to a Vero 29 Cob light. "Tomatoes" Really made me laugh.. :)
;-)
What make and model is that meter you're using? How can that not be a must for indoor growers to dial in perfection?
As stupid as this may sound (since it probably is) wouldn't wrapping the walls with actual mirrors give me maximun light reflection? It would actually reflect around off of it's own self under the canopy until parts of the plant blocked it's path. This the need for a meter to test angles of deflected light and the strength. Or I suppose if I had a meter I could answer the mirror question myself
can you do videos on the common 60W and 75W EcoSmart Homedepot LED lights?.. these lights are way cheaper than the ones found on amazon and I'm curious to see how the PAR values compare.
Question: if I'm growing auto flower and I don't need to reduce the light on cycle time (because I don't need to induce flowering), then can I get away with less PPFD for flowering (because the exposure time would be longer -- simple math)? Thank you
Nice review. What do you think about waiting on the 301h, vs the 301b that this uses?
Al I just received my SF 2000, I will be growing lettuce and Microgreens , about how far should the light be? I have no side walls. Thank you Mike
I also got the dimmer switch with it.
You could start with 24" and see how that works for you.
Great vids main man! i just subbed. I have a question for you that i could not find an answer for yet online..So here goes..Do you know if late day leaf droop is a sign of enough light saturation for that day,(my leaves start dropping around the 10.5 hr mark on 12/12) and that I can potentially fine tune my light height and/or light schedule, for longer nights for example?
Thanks for watching and welcome to my channel! From what I've heard, some growers experience leaf droop and they consider it to be normal. Like a natural part of the plants' circadian rhythm. Perhaps other viewers can shed light on that from their personal experience.
First time: Virginia where one can only grow 4 plants What do I need? I am currently looking at: MARS HYDRO Grow Tent Kit Complete 4x4ft TSW 2000W Led Grow Light Dimmable Full Spectrum, Indoor Grow Tent Kit 48"x48"x80" Hydroponics Growing Tent 1680D Canvas with 6 Inch Ventilation System. Is this what I should purchase?
@3:30 XD
Great vid as usual, lots of fantastic info. You should check out the DIY HLG quantum board lighting kits. Very little assembly required, very low cost for high power lights.
Nice video thanks
