That light is garbage, it will never come even remotely close to replacing a 1kW light. It only pulls 110 watts. It could sprout and grow some seedlings but it's probably good for about 2 sqft.
So should I put both of em in ?
Even 2 would be inadequate in a 3x3.
You can grow a plant with those lights, however you will almost certainly find yourself asking why don't my plants look as good as some of the other plants I see around this forum. Those lights will also produce underwhelming flowers, and that problem will be compounded by the more square footage you try to cover per light.
Sure, They will work. Just undersized for a 3x3 tent.
I feel like such a dummy I thought the lights would be good I got two of them in there now otal 1000w both cranked up all the way my temp and humid is fine. Will I harvest good buds ? Or am I wasting my time
That should say fimming not dimming.
You can get a 240w kit from Alibaba for about $150. Way better than the 220 actual draw on those crap lights.
You can absolutely grow under that light & probably even grow up to an oz . Is it the best ? No . For less than $100 your best bet would be an HLG 65 . Other than that you are better off dropping some coin for better LEDs . Even in the $150-200 range you will see a vast difference from the light you are using
I bought a spider farmer 2000 what would my yeilds look like now ?
If it pulls 200w at the wall that is a pretty good gauge for your grow. If you pull 1 gram per watt you would get 7 oz . It’s doable and with that light you could probably get all the way up close to 1.75-2 grams per watt if you really know what you are doing . Id run that cheap light with the spider farmer too, UV helps prevent mold and other harmful bacteria
Is that 7 oz a plant for autoflower or for all 3-4 plants ?
Would another sf1000 with the sf2000 be to much ?
No it wouldnt , and its pretty hard for there to be “ too much “ light , cannabis is able to use a lot more light than most plants
