Thanks for the response! Lights are the only things that confuse me really

I live in southern states and it gets pretty hot and humid outside, even the breezes are warm, would this effect the plant much stress-wise? i usually wouldn't be worried about it but recently the summers have been harsh. Oh, and the strains i'm having are from the attitude seedbank, i can't remember the name, my gf is ordering them, but something like the pineapple express anddd i can't remember, i'll have to ask and tell the correct names later.

I planned on setting up 2 150 hps and 4 cfl lights around the sides and rotating the plants nightly so they can get all the energy they can. for now i can only find a good space that'd fit 3-4 plants. would a 20/4 cycle be better than a 24/0? also, do you mind if i ask, how long do they stay in veg stage and flowering stage? should i bother with nutes while on veg stage or will it pass by too fast to even bother?

and thank you ^^
