theory testing of styles
Cab Re-Do for small perpetual grow
Cab worked well for what it was intended for. But for this,, I need more control.
2 Larger replacement fans on top, 1 added low.
All top fans are exhaust,, bottome is intake.
Baffled bottom fresh intake vent
Simplified the wiring, added speed controller for top middle & bottom fans. 2 larger top outside fans are voltage controlled by adapter.
Electric trolling motor box provided materials.
Air chamber. Reduces light leakage (more stealth), can blend air,, and filters.
Rough paint job. May finish paint in better (outside) weather.

Damper style contraption. Should be able to have lower fan suck cooler fresh floor air or recirculate / blend with the heated exhaust from top.
Way it's layed out,, I hope to eleiminate any internal need for fans (too much room to waste).
Air box completed. (see the arm for damper control?)
Filter material is from pet shop. Activated carbon / fuzz pad type material. Light duty but not too worried about smells in this stage of growth. Pads cut to size and double backed taped into position (commercial 1" SUPER sticky crap). Also one on the bottom for sresh intake side.

With "Y" splitters it has 4 CFL capacity on bottom. Left side will be first 3 weeks (2 plants veg cfl),,, right, second 3 weeks (2 plants 1 veg & 1 flower cfl).
False back is fan diffuser for air flow (may need to be tuned a bit).
Well, that's about it.
Tomorrow will be a big plant day. The moms in the closet are overdue for attention. Couple clones need bigger pots.
I'll include a brief update.
Next stop,, get the closet converted to perpetual.
