hmm, almost same setup 400w hps here and 4 plants also jacks classic AK tho mixd with a strong indica im at only 28 day flower but wow, got a weight?

oh and those are 3 gal containers?

side note i keep my AC from freeze'n up by blocking one of the side air intake grooves area deally... try it, i did but be carefull dont wanna burn out... great results for me, think it draws more from front preventing freeze up 65-85 deg F. max
