Also, i just ordered 4x 2.2 gal auto pots since they fit the same trays that come with the 3.9 so i can run 4x 2.2 in the tent on the auto rez and ill use 2 of the 3.9 gal pots as reg hand watering when i get my light to use the whole 4x4. Don't want to push 8 plants in coco under good led with Mephisto genes to add to it my tent will be crazy over crowded. For the hell of it i got 4x air domes too for the 2.2 ppts just to compensate the lost room from the 3.9 pots. We shall see my tent go to full usage by the end of this month to next.
