Installed exhaust fan in veg chamber. 6" 240 cfm can fan. Installed velcro on opening to seal. Drilled a few more holes in the deck of the chamber to accommodate the updraft from the fan below. I think the updraft, the exhaust fan and a rotating fan inside is about as prepared for the heat as I can be on a budget. The use of CFLs will help also. Not the most aesthetically pleasing project but functional...🤠
All closed up. Fastened with velcro.
Oleskool DIY CFL light from 10 years ago! Funky huh!
Below deck air mover for updraft.
