5 weeks under a 1000w hps 600-900ppm of co2. How much more wieght will it put on. She is an Afgoo. This is my 1st grow with a 1000w. I want a QP, I think some of the buds will be a half oz or more. And ther are 2 colas that look like this!
0.75g/w would probably be a decent gues i think? it comes down a lot to what strain you grow but you have some nice topping/lst going on there so id say at least. i dont think you will hade a problem getting a QP. my first grow ever was in a DR90 with 1000w growing 20 autos in 3.6l pots and i got 437g.
Like i said i think you will do just fine. your plants health tells me so
