1. Cabinet Construction - Insulating Stress Panels composed of 1.5" Polystyrene insulation board surrounded by a frame of 1.5" x 1.5" Fir. Everything skinned on both sides with 1/4" luan plywood. Strong, relatively light, very well insulated. Panels are joined to one another with 3" wood screws. Panels can be disassembled easily.
Interior dimensions - 31" Wide x 17" Deep x 45" Tall

2. Ventilation - Active Exhaust to outside. 6" rigid ducting with 424 CFM inline fan on diy speed control rheostat. Passive intake using 6" flexible insulated ducting. All air brought in from a heated and air-conditioned room, thus box is effectively heated and air-conditioned also.

3. Main Lighting - 250 Watt HPS with remote ballast (outside of box) 250W Metal Halide conversion bulb used for veg.

4. Side lighting - 40 Watt total 24" T12 fixture. This probably does very little, I can place it in/under canopy, also provides different spectrum than main light.

5. Moveable Hood/Divider. - Effectively separates bulb heat from plant area. Bulb shielded from plants by double strength glass.

6. Air circulation - 9" oscillating fan (may have to eventually be moved to underneath canopy as plants grow toward max height)

7. Temp/Humidity Meter

8. Vegetative Pots - approximately 1.5 gallons. Cut down from paint buckets. Screws around outside lip are for eventual LST.

9. Drain - (can't really see it from pic) Pots are over a drainage tray that is plumbed into air-conditioner condenser drain. I can overwater and flush without moving plants from cab.

I regret not taking pictures during construction, but I was in a building frenzy. Sorry.
I don't really cover it all in this post, so feel free to ask any questions or make any suggestions. Thanks for your time and feedback.
