I like to help out mate, but come on dude..make a little research effort.
A first grow that size will fail without it...honestly, I don't mean to be harsh...
I'll start you off; 600w hps will do 1m2 nicely, but there are many alternatives...
Yea ive done a lot mate lol I was guessing 4 to 6 600w lights ? Just wonder how many plants realy with enuff space to get enuff light to all parts of da plant an get a nice yield of them thanks
Yeh man, 4-6 600w is bang on. I wouldn't bother going for 1000w as you can get more even light spread out with 600w's...
Plant numbers would depend on grow method; Scrog if you're wanting a nice even canopy, but I love it so I'm probably biased
Accept my apologies for my presumptuous 1st post...neck wound in!
