I just bought1200W/1500W 289/1365 LED Plant Grow Light... it was 50$ off wallmart a month ago should be showing up tmro.... I have a 3x3 tent should this light b enoug for 4 plants...
I wouldn't count on it working well in Flower. It's probably good enough to keep a plant alive. I warn people all the time about buying cheapo lights. They are built like shit & are a Fire Hazard.
I've had 3 lights melt where the plug goes into the lights when I bought the cheapo $50 lights.
Besides that they only produce small buds because the PAR level is inadequate. They just aren't worth it. But you can get through a grow & probably get 2 oz. per plant which will give you money to buy a decent light. That's my thoughts on it. I'm sure it's not what you were hoping to hear; but I'm being honest.
No need to do 4 plants in a 3' x 3'. You can do 1 plant with topping & LST & get the same amount of weed as 4 plants. You can fill a 3' x 3' tent wall to wall with 1 plant.
This is 1 plant with 5 weeks veg & 7 weeks flower so far.
Keep in mind your plant will double in size when you switch to 12/12 for flower.
I would use a light like that for early veg and clones....that's about it and that's even pushing it. If money is tight HPS/MH might be the best option. If it's not....look into Mars-hydro, Budget Led, HLG and Syder-Farm.
What are some specs that I should be looking out for? Would like max yield and thc.. Would like to spend 100 to 150 if this light I bought is garbage. What size is the best for it
