How much is lost to evaporation?
Downstairs I’ve been using it to manage humidity - not vacuuming during veg to keep it higher down the chain of tents (you can see a close up in the latest video in my 5x5 journal about 45 seconds in) Post flip they’ll be kept much dryer.
The tray on the bottom in the photo below was scrubbed after the last grow - its 3 grows old. Some serious salt build up. Gonna get scrubbed again tomorrow when we fill that room yay!
No comment to the impact of those salts. None of our grows have the pot bottoms in contact with a full surface, the airpots leave a gap where the sides stand proud of whatever is below as you know. The solos are held by the frames.
We did out first two plants in fabric pots. I sort of miss them. I think they might aerate the root zone better than airpots. The advantage airpots have though is the sidewall/structural support.
Ooph pots on the brain. Got 35 or so to up pot tomorrow. My wife is going to be so busy I worry if my lunch will be late
