Don't waste your money on blurple lights.
You can get a proper, full-spectrum Samsung 301 diode like a Spider Farmer SF-1000 from Amazon, or the many equivalent sellers available on Alibaba, Amazon, direct from sites, etc - and you will be much happier with your results. While the number won't be as inflated (that light is 100 watts, the Mars Hydro 1000 is ~150 watts, etc) they're actual numbers and will let you flower a 2x2 tent quite comfortably.
Yeah, sunlight in the window vs direct sunlight outside can be different. Some windows have a uv protection on them which could make it so the plant isn't getting the full spectrum it needs.
If you can, either put the plant outside most of the day and bring it in for the dark period. It will take more work but it will be better than a 36w light.
That or get a 100w led. https://www.amazon.com/Spider-Farmer-Dimmable-MeanWell-Spectrum/dp/B07TS82HWB
They have a $30 off coupon right now. Which is really the cost of the light, its more just so people think they are getting some crazy good deal.
I was gonna suggest this but you might wanna save about $100 more bucks to get something above 200W with that tent size. 2022 New SPIDER FARMER SF-1000 LED Grow Light Use with Samsung LM301B LEDs Daisy Chain Dimmable Full Spectrum Grow Lights for Indoor Veg Flower Growing Lamps with MeanWell Driver https://www.amazon.com/dp/B07TS82HWB/ref=cm_sw_r_apan_glt_i_166MA8TZY7Z36JV5ESJG
This was what I was thinking. It probably spent 3 weeks in and out of the garage mid 50's but sometimes warmer sometimes colder. No light but brought out for some days. The basement lighting is a couple of these leds- https://www.amazon.com/gp/product/B07TS82HWB/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Temperature is mid-60's. New Jersey, late fall before the frosts. The leaves were yellowing when I brought it in so I added fertilizer for the first time since mid-summer. I will drop all the buds.
Yes it is Daisy Chain Dimmable Full Spectrum👍

Thanks! I was just looking at this spider light on Amazon and I think it might be the one. I’ll take the one in now out and replace with this SPIDER FARMER SF-1000 LED Grow Light Use with Samsung LM301B LEDs Daisy Chain Dimmable Full Spectrum Grow Lights for Indoor Plants Veg Flower Greenhouse Growing Lamps with MeanWell Driver https://www.amazon.com/dp/B07TS82HWB/ref=cm_sw_r_cp_api_glt_fabc_Y28Z92DBWG7BY7CSS61A?_encoding=UTF8&psc=1
Honestly, once you get into this hobby you might as well buy something you'll keep for a while. I've heard good things about mars hydro but I've also heard that people switch to HLG or Spider Farmer afterwords. HLG lights are expensive, I'm loving my sf 4000 and sf 2000, if you can swing 160 I suggest this https://smile.amazon.com/dp/B07TS82HWB/ref=cm_sw_r_cp_apa_glc_fabc_8CDADNCXT1PAJ3P93V1J and a small fan. It's worth it to just take the leap. When I got in I was in a cabinet running a tiny blurple, 2 tents, 5 ac fans, and 6 lights later I'm comfortable saying it would've been worth getting what I wanted from the beginning. If you start with something closer to what you'll use later it will be easier.
It is a nice start, good job on the reflective sides, I like how using those sheets you improvised the reflectivity and enclosure of a tent while being in an open space.
I am a fan of the SF1000, they also have a cheaper SF1000D.
For that price on amazon I’ve been looking at Spider Farmer SF 1000 LED Grow Light with Samsung Chips LM301B & Dimmable Mean Well Driver, Sunlike Full Spectrum 3000K 5000K 660nm 760nm IR for Indoor Plants Veg Flower https://www.amazon.com/dp/B07TS82HWB/ref=cm_sw_r_cp_api_i_F82WDb5GERB2X
But I’ve just started looking in aliexpress/alibaba and you can get one with 2 panels for the same price as the single panel on amazon
I’m using a spider farms led that was like $160 I believe, my baby’s are loving it. Your light should be the thing you put the most money into since it is directly responsible for how much you will yield. Inside my tent looks like simulated daylight, no blurple

I’m new and did t want to jump with both feet but ended up with Spider Farmer. I am loving the results. It’s more pricey. I have been reading you can go cheaper with a knock off just make sure they use the Samsung led. Hope this isn’t to detailed.
It honestly depends on your tent size, man. Different lights have different coverage and ppfd ratings. This light can cover up to a 2x2 area with great yields. The 4000 version is more expensive at $530 on Amazon, but it will cover up to a 5x5 with amazingly even spread. (The sf2000 is the mid range light for up to 3x3 coverage. Not sure the price. 2 sf2000 are better than one sf4000, and same goes for sf1000 to sf2000. Better coverage and more mobility with more lights. But get a quantum board!
Claims to replace a 1000 watt MH/HPS light, yet only powerful enough to cover an area of 2x2 feet for flowering? Something doesn’t add up here. A 600 watt HPS is strong enough to cover 4x4 for flowering very light-intensive plants, and a 1000 watt traditional/old school light will do much more than that. These other lights are also on sale right now on Amazon in several sizes for half the normal price and feature the newest/most efficient LEDs.....
So I guess I should have mentioned the height of my tent is 48". I'm not sure if that becomes a problem since it's probably a little shorter than I'd like.
I am looking at those Kingbrites on Alibaba you mentioned. I also came across the following brand on Amazon that sounds decent. Would you think this be fine?
I’m a fan of the Spider Farmer LEDs i have! Got mine on Amazon Link. Ignore the “sale” pricing its BS. They are slightly over priced compared to some other boards on Alibaba but they work great.
Don't do that buddy, those people are morons, white paint reflects more light and less heat than tin foil. This is the veg tent i keep in my bedroom. It is an 18x32 inch tent ($60-90) under a $200 HLG quantum board. The whole set-up was about $300.
The light is pretty extra, and I would recommend a light with more red instead of one like mine which is more blue for vegging. This is the red version of the HLG I have and this is a slighter cheaper amazon version. I know this is a little bigger than you are looking for but i highly recommend something like this for an indoor grow. The tent I have would perfectly fit into a 2x4 foot closet too. Will even fit in a 2x3 foor space. You can definitely also find even cheaper similar lights if you search something like Amazon or Alibaba.
The main things are to avoid serious errors.
Remember that inverse square losses become significant well before you double the distance. You have to compensate, usually with more power.
Never uncritically believe the rating assigned by sellers. Make certain that the wattage number you are depending on really represents actual consumption. There are no real bargains. If it seems cheap, it's likely misrepresented.
Don't pay too much attention to the area a seller says the light will serve. Read the sellers materials. For instance this light from a well known reputable seller.
https://www.amazon.com/Spider-Farmer-Dimmable-MeanWell-Spectrum/dp/B07TS82HWB/
They offer three coverage plots for three heights. Look at how those numbers behave. Forget the actual numbers for a second. Look at the 18 inches plot. The numbers at the extreme corners are not reduced by a large proportion from the center.
Now look at the 14 inch and 12 inch plots. The center numbers are, of course, higher than in the 18 inch plot. But the numbers at the corners of the two-foot area are very reduced. Worse even than at 18 inches. So we can see that, as we lower the light, the most effective cone of light gets smaller. It would be more obvious if they showed a much larger area and how it was effected.
What this tells us is that we can gain power by lowering, at the expense of effective coverage, if we think we need that power across the growing area. When they say it covers 2'x2' (or 3'x3' for different needs), they are really qualifying it as being true when it's a 18 inches, and you accept that lesser intensity at the center.
But wait, as they say. There's more. Greens like lettuce have much lesser minimum light requirements than mature flowering or fruiting plants with higher energy needs. Lettuce will be quite happy with a PPFD number of 300. Mature plants may want more like 400 to 600. So if we're growing all greens, we could even raise that light to 24 to 36 inches and cover a larger growing area. If we had a tomato in there with our greens, it would like to be in the center where it will more quickly grow into the higher intensity distance, while lettuce will stay low and be happy at the outside. I can use budget light bars on my lettuce shelves. I really don't want a lot of power there, because even lettuce will grow up close to the light. Through dumb luck, I het a happy spot. They grow like mad. Their lower leaves do well because they're not tall. And they can grow up to touch the light without obvious harm.
If a seller doesn't provide any such information, there's probably a reason. Generally it's that the light just isn't very powerful. They likely nowhere reveal the actual consumption, because it's so low. To be fair, many only show those little four-wand lights being used on low growing and low light type house plants. But some buyers will miss that point.
Sometimes, it's that the beam angle is so wide that it almost has to be touching the plant to do much good. It matters, because most of us at some point want to grow more seriously and grow a wider variety of plants with differing light needs and different heights and growing cycles. and we both want to not waste money on lights that aren't adequate or of the wrong configuration and want to deploy them for best effect.
Thanks so much for the detailed response. So would 1 of these be good? Or will will I need 2?
I just got SpiderFarmer LED lights. They are pretty awesome, not cheap, but quality.
Blurple lights are a waste of money.
The numbers they put out "on paper" are vastly inflated compared to what they deliver for plants, especially in flowering, and your end result will be fluffy, low-weight nugs.
What you ideally want to look for are Samsung 301b or Samsung 301h diodes with a quality driver- something like a Spider Farmer SF1000 or Mars Hydro TS1000W is a fairly typical, budget-friendly beginner light that will let you take a single plant from seed to flower.
-
Don't buy lights that use Lumens as their power measure, that's a measure of the amount of visible light to the human eye. You want to see PPFD charts and PAR values - which you can compare to growing guides online that tell you what intensity you should be at in a given time period for your plants.
Tent Sizes
| Size | Height | Sqft |
|---|---|---|
| 2x2 | 48" | 4 |
| 4x2 | 60" | 8 |
| 3x3 | 72" | 9 |
| 4x4 | 80" | 16 |
| 5x5 | 80" | 25 |
I strongly recommend getting the largest tent you can fit in your space for the purposes of grow height. For example, maybe you only have the budget for a 100w grow light to start, you should still get a 4x2 tent or 3x3 tent and just use half the space, because the extra height will give you a LOT more flexibility and comfort.

Light Options
​
| Type | Price | Explanation |
|---|---|---|
| Shop Lights | $1.50/watt | Don't buy, these have a poor usable light range for plants (CRI / PPF) and are more expensive than grow lights |
| Blurple Lights | $1.00/watt | Don't buy, these are outdated and have poor yield in flowering |
| Boards | $0.50 ~ $1.00/watt | Excellent budget option for growers, luxury features like samsung lm301h diodes and meanwell drivers cost more but are nice to have |
| Bars (coupon: "reddit") | $0.50 ~ $1.00/watt | Excellent commercial / large scale option for growers, has excellent coverage and flexibility in intensity for different types of grows |

Exhaust
...just get an AC Infinity 6"+ setup and be done with it, the budgets options are all poor quality.
The one you linked to is a useless blurple light.
Get a real LED panel- a 100w panel will do the trick and they are LEDs, so very low cost.
Example.
I got these Spider Farmer lights and they're awesome. Have three different versions now, but these would probably be the best for your use case.
No dimmer :/ although I was just looking at this:
I use Spider Farmer lights and they're great. Got a few of each.
I have a KingLED 1500 Purple for veg and a SpiderFarms SP1000 for flower, but so far running both during the entire grow, veg, and flower, has gotten me "dispensary" herb. I would suggest at the very least, a 1000w LED or COB setup for the size of your grow space.
Thank you. I have these: https://www.amazon.com/dp/B07TS82HWB/ref=cm_sw_r_apan_i_W6X21DZA3HT3WHV4MGDD?_encoding=UTF8&psc=1
I have some all purposes miracle grow fertilizer but only occasionally use it, maybe once every 2 months or so
I'm running 2x Spider Farmer S-1000, I had a Mars hydro, but LEDs burnt out on it so I decided to go with SF.
I’ve got 300+ seedlings growing under a Spider Farmer sf 1000 Led.
Well, six watts is absurd. Wattage can only be a very rough way to choose lights. But I have always used a rough rule that usually comes close. That is 32 watts per square foot (about 1,000 sq cm) growing surface when mounted at about 18 inches. By that rule your approximate 6 square feet (5,400 sq cm) would call for about 200 watts.
But, again, that is very rough, but I think it suffices to allow height adjustment for corrections.
Part of the problem is that the plain rule doesn't account for light configuration. Unless the beam width happens to be such that it impinges only on the growing surface, some light is lost outside the growing area. By in my experience, the same rule works, even when some light is lost.
It's much easier if the maker provides, as many do, a PPFD map like the one here.
https://www.amazon.com/dp/B07TS82HWB
You can immediately see how the difference between center and edge changes with height. It's a bit complex, because all the LED's have the same beam width, so there's a point in height where the coverage areas of each fall on or miss part of the growing area. Fortunately, it's rarely that critical. And you can use PPFD numbers to find Daily Light Interval at different points, at different heights, and for different daily hours.
There's a PPFD chart here:
You will see that for any plant, there's a favorable DLI goal that can be met my changing light hours or PPFD rating or both. Which also means you can use height in the calculation. You mainly don't want to get off into the green zones of inadequate or into the red zones where you'll burn plants. And you will see plant requirements by two experts, one being specific for lettuce at 14-16 DLI and the other simply calling it 12+ for lettuce. And lettuce is indeed so tolerant that probably only a very careful academic could find enough to measure to get picky.
But you can see the maker of the above light says it's good for four square feet, in this case 25 watts per square foot, which is definitely in the ballpark of the rough rule. Which is why most people rely on the make rating, and they do fine.
So it might look like by maker ratings that you would want three of those lights for your six square feet. But now we have to reckon with the fact that we just gained back a lot of the formerly lost light that was off the growing area of just one light but now falls on plants. So it's more reasonable to call it two of those lights, which is 200 watts, which is where we started by rough rule.
And note that , at 18 inches, the average PPFD is about 475, making the approximate good DLI for lettuce from eight to ten hours. It all seems to be working.
I'm a pretty big fan the Spider Farmer lights.
I have a few of these.
https://www.amazon.com/Spider-Farmer-Dimmable-MeanWell-Spectrum/dp/B07TS82HWB
I got this Spiderfarm light, based on multiple users reviews and San Pedro Mastery videos:
For what it's worth - I have a few of these SpiderFarmer LED lights and they're awesome.
But with no shield they do hit the eyes somewhat fierce. Though my plants are in another room, it can still be somewhat annoying.
I'm going to be getting a big light for the winter and am considering a few of these.
Thank you I use this one, it's even cheaper now than when I got mine. https://www.amazon.com/dp/B07TS82HWB/ref=cm_sw_r_apan_glt_fabc_dl_KBYEQYZAXZ6CE9SW0T4C?_encoding=UTF8&psc=1

https://www.amazon.com/Spider-Farmer-Dimmable-MeanWell-Spectrum/dp/B07TS82HWB
You need some more lights in there, she's leggy. Just add like 4 more CFLs.
Or buy this
Unless you have light meter, don’t turn it down because you will need to use their provided max strength PPFD chart to determine how high to place it above your plants. You can convert PPFD to footcandles by dividing it by 0.17 so at 12 inches away, directly under the lamp your plants will be getting 6076fc which is almost direct sun and will burn the foliage. At 18 inches they’re getting a more modest but still quite high 3541fc in the very center of the lamp. I run my growlights where they get about 2000fc and that provides good growth without scorching (but it’s still too much for pothos and trialing philos). 8-10 inches of what I assume is 7000-8000fc is equivalent to direct sun and will SCORCH your plants.
Use the amazon listing’s PPFD chart and divide number by 0.17 to get foot candles. Then cross reference HPJ’s minimum light levels chart (pay attention to the commercial light levels section and try to emulate that for max growth). If you need to figure out how long to keep them on, he has an article to determine that too.

I have a few of these SpiderFarmer lights. Very nice lights.

I am in Charlotte...temps are warming up and my basil are thriving in kratky so far.
References to silica with lettuce: https://www.google.com/search?as_q=silica+lettuce+hydroponics+filetype%3Apdf&as_epq=&as_oq=&as_eq=&as_nlo=&as_nhi=&lr=&cr=&as_qdr=all&as_sitesearch=&as_occt=any&safe=images&as_filetype=&tbs=
So you settled for indoors with lettuce huh? Dr. Kratky's video is what got me started and he was 100% outdoors. I'm thinking maybe I do LEDs for a week to 10 days then move them to shade outside?
The leds I am considering.
was looking at this one... do you think id need multiple for the size tent I have?
I use Spider Farmer SF-1000, the bang is worth the buck. It is like most things and especially LEDs, you get what you pay for. I have 4 of these and grow lettuce, peppers, tomatoes, and they are also great for starting plants. You can also calculate DLI and get accurate with the amount of light you are giving certain plants (link below). I have had great performance with these lights.
https://www.amazon.com/gp/product/B07TS82HWB/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
After looking at that and comparing lights I've decided on this one. :)
​
Okay, that seems like a very reasonable budget for a very good 2x2 light. I have an HLG QB288v2 (3000k), which seems perfect for that size tent, but it requires assembly, and it's on the expensive side. (It was . I didn't find the assembly difficult at all, it just involved screwing things together and connecting wires (including matching a couple by color). I've comfortable working with electronics, though.
While I haven't used one yet, the Spider Farmer SF-1000 looks like another good option. It comes pre-assembled, I think it's UL-listed (though I don't see that on the amazon page anywhere now, odd), has a 3 year warranty, and it's $150. The main point against it is that it's only 100 watts, but the PAR/PPFD values still look good, and comparable to my current light at 18". If my HLG QB stops working, I'll probably replace it with an SF-1000.
I actually just realized that I did the math totally wrong for the power, that the 1200 watt doesn't actually put out 1200 watts and while it is advertised as such it actually puts out ~241 watts as found in the in the listing description. Legit quantum boards put out what they are titled as because they use crappy Chinese LED chips.
Honestly I don't trust either of those because of that. They won't ever actually put out the actual PPFD advertised. I did my best to search for alternatives and was able to find this one quantum board that is relatively the same price. It uses Samsung LM301B Chips. Samsung is the industry leader in LED chipsets so I stick with their chips exclusively. They do have their new LM301H chip which is even more efficient but costs more, and while it's nice, the LM301B is good unless you have the extra cash. This board also has UV and IR leds that are beneficial to the plant (especially the UV where there has been a study that UV increases trichome development by about 25%, and plenty of growers have reported this.) Here is a good article that explains UV and IR benefits to plants. The Phlizon has a couple of UV and IR diodes but I saw a Q&A question that said it's not actually a legit UV chip. The Mars Hydro did not describe it to have either but another Q&A said that it only has IR.
The color spectrum is fully covered by this board. Here is a GrowWeedEasy article that explains what plants need very well. It's extremely informative. Here is a link to a Spectrum Graph found on that article that shows what wavelength the plants take in energy at. For reference, Chlorophyll A is what matters, however Chlorophyll B does need some energy but passes most of its energy to A.
A second good board I found on Amazon is this one at 301b3500k.
If I had to choose from the Phlizon 1200 or the Mars Hydro TS 1000W I'd get the Mars Hydro. I took a look at the Phlizon listing and that they got different numbers for the PAR value from the description vs the pictures. But they are still chinese products being resold from Alibaba.
what do you think of this? I have had bad experiences with alibaba in the past and would rather not use them.
Some quick options to span through price for you to compare, spider farmer 1000, Mars Hydro 1000, Vivosun, and MAXISUN.
Personally I would go with Spider Farmer, second choice is Vivosun. I like the Vivosun fabric bags. Price and quality seem good, I went with 7 gallon. Happy with my choice maybe I would go with 10 gallon if I could do it again. I am only growing like 1-2 at a time.
Here is the light I bought, I bought it because was a local company and it has both a bloom and veg setting, along with UVA that can be turned on and off and its also dimmable.
If you are looking to buy something off amazon I was recommend this light, a ton of people recommend them on a few subreddits.
I'm not an expert on lighting but I found this channel to be very helpful.
Amazon link for same light just a little more $ but way faster shipping https://www.amazon.com/dp/B07TS82HWB/ref=cm_sw_r_apa_i_ejcYEbB7HHTQ4
Can anyone confirm if it's actually the exact same board as Spiderfarmer? Looks to me like Spiderfarmer just puts their logo on it and that's it - so $88 shipped direct from China vs $149 on Amazon.
Even the photos in the ad are identical: https://www.amazon.com/dp/B07TS82HWB/ref=sspa_dk_hqp_detail_aax_0?psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzTTVJSlFFNkZTSzVIJmVuY3J5cHRlZElkPUEwMjcxNTUxOEM3Sks3MzBWNzA4JmVuY3J5cHRlZEFkSWQ9QTA5NDYyNTUxUURWMklWS0ExRlMyJndpZGdldE5hbWU9c3BfaHFwX3NoYXJlZCZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=
