I'm thinking about growing 2-4 lowryder #2's in a 50cm x 50cm x 80cm (19.5" x 19.5" x 31.5") cab with cfl's, how much wattage I would need to get about an ounce + seed? Would 125w or 200w econolite (or envirolite, I don't really know the difference between those two) be enough? Or should I get a 100w HPS ( I can't find a lot those where I live, there's a really small selection) P.S. I won't go for more than 200w since the electricity prices got more expencive now ( .37 cents). P.S.S. Hi everyone, this is my first post here, though I've been lurking around for quite a long time.
Watts aren't the only thing that determine size. Veg. time, nutes, carb's, ect...those also determine size of a plant. With a single 150w, or 200w CFL I wouldn't expect a big plant. Between the 2-4 plants you could get an O dried.
