You could well be right, certainly for the greenhouse plant. Not too many sunny days where I live. No fan but I do try to keep a good airflow through the greenhouse by opening all the windows. Have been a lot of dull days lately which I guess slows down the drying rate as you say. Will be moving that indoors once I have the space.
That's awesome man. I love the idea. It's the best of both worlds. Stability and more Oxygen to the roots. I'm gonna have to try that shit. Nice job.
Moving plants from outside to in is just asking for major bug infestations. But back to the "big plant" not drinking much..... its not flowering or anything. If you chopped that bitch down and put it on a scale it might weigh what, 4-8 ounces. If it was in full flower all bushed out, it would weigh multiple pounds. Plants just dont use that much water when they are vegging like that.
