Hello welcome friends.
I've been thinking about starting a new thread for a long time now so here we go. Enjoy the show!
Here's the flower room. It is a 9'6"x13'6"room built in a wide one car garage with 9' ceilings. There is a 1000watt MH bulb and a 1000watt HPS bulb hung bare bulb on a Light Rail 5.0 light mover. The mover only moves about 2 feet with a pause on each end, just enough to eliminate shading and to move the hot spot. This allows the plants to be pretty close to the bulbs, about 18 to 24 inches. The plants are rotated 180° every day. The lights are on 12 off 12.
There's an 8" intake fan and an 8" extraction fan that run 24\7. The intake is carbon filtered and the exhaust is on a 4' tall carbon filter. I've installed 2 exhaust ports each with it's own 8" fan and giant carbon filter, one blows heat out of the house through the roof in the summer and the other blows heat into the center of the house in the winter. There are no smells at all.
I also built 2 walls around each of the exhaust fans and filters that are in the corners, but I stopped the walls short 6" from the ceiling so that the exhaust air is pulled from the top of the room where heat rises to.
There is a boxfan on the floor blowing up at the bulbs. There are also 2 visible mist humidifiers and another box fan that blows at the humidifiers away from the bulb side of the room. The humidifiers are removed everyday day at lights out and cleaned, dried, refilled and replaced at lights on.
Apologies for the crooked shot.
