Do you think it's too late in flower to give a heavy defol on Kerosene krash girls? With as thick as they are and the humidity problems you're dealing with , I'd really hate to see things go south If something happens to the humidifier without you knowing .
Even with the good air flow I have set up in my 4 by 4, I would be kind of afraid of microclimates. My air flow moves from front to back and bottom to top with the exhaust fan running at all times, with it going higher after meeting other parameters Of temperature or humidity. I would probably have to add another fan at the bottom to ensure full circulation down there. I think I'd still have to defoliate at least a little bit for air flow. I don't see how I conservative defoliation with air flow in mind could harm them.
Looking good as hell and hopefully the side lighting you're getting will be helpful also!
