Soil staying wet? Maybe. I tend to underwater regularly rather than overwater irregularly, but it has never been an issue before. Drainage is excellent, however, and if I had root rot or some other issue due to too much water, the plants wouldn’t be nearly as healthy as they are.
This was 6 days ago and they look the same except I have defoliated more and removed some less productive side branches to thin things out and allow them to breath more. Cogitech's Conservatory - #65 by cogitech
Air flow: 6" active intake rushing in the bottom, left to right - level with the pots, but angled up about 30 degrees to encourage that fresh air to move through the stalks. 6" fan blowing through top of canopy, right to left. The fan creates negative pressure which helps draw the intake air through the (defoliated) bottom third of the plants, and then up through the fan and across the canopy. 6" active exhaust with carbon filter. The fan that drives the exhaust is plenty powerful (so much so that I had to open a hole in the loop to reduce negative pressure in the tent (sides were sucking WAY in)).
