Basicly. 3 gal or 5 gallon pots ...for blue himalaylan diesel and shark bite... I even thought 3 for shark bite and 5 for BHD bc shark bite is a small auto strain...The reason I'm even considering this is bc I have a 4 x 4 with 1000 hps and I can fit more in the tent with small pots but don't want to sacrifice yield....any opinions would be fantastic thanks
