It's been three hours with the new armoire on. The inside temps are running just as well as the small SuperBox with CFLs. Den's temp is 67 degrees F. Inside the grow area is running 75 degrees F. I can actually touch the Cool Tube w/o any heat felt.
It's also freaking BRIGHT in there. They are under an Eye brand Hortilux Enhanced Spectrum Super HPS Grow Lamp. They are designed with enough violet, blue, green spectrum to be used as a standalone light source throughout all phases of cannabis production.
Very pleased with the outcome of the project. Going to fine tune the armoire's construction. Mounting the power strip to the inside bottom compartment. Need to light tight it with reflective foil strips. Set up a tray to keep the girl's off the floor of the box, etc.
