Have a 600 watt air cooled running in a 4x4 tent average dark temp is 75 and about 84 with the lights on (it's midsummer where I am and can't seem to get it any cooler) I feed with technaflora line of nutrients on a feed water water sched. I am at 6 1/2 weeks when photos were taken and the strains are mazar (Dutch passion) and Pineapple Express (g13 labs) vegged for less than 2 weeks . Wondering about opinions on an estimated yield
