Sorry. Didn't upload in order. But you'll get the drift.
For clone / seed / veg only.
EDIT
Bottom fan is intake, wired with top center exhaust and on seperate plug.
Top outsiders are exhaust on the light timer. Speed controlled.
Minn Kota box on back is a light blocker, with a baffle. Bottom also has a carbon fishtank filter. With the baffle in the kota box,, plus the bottom baffles, I can control air flow pretty well. Can blend exhaust to keep warm or draw fresh from bottom, or mix with intake fan. (I like control)
Whole cab in full operation about 200 watts max.
