Outdoor Grow Box
Last fall I decided to build an outdoor grow box. My little indoor area can only fit 4-6 plants and the Mrs. wouldn't let me use the spare bedroom, so I thought, what the hell. It's 4' square and the side walls are 6'. The back is a foot higher, which gives me good run off and on the inside, a place to put my fan. I put the overhang on the front so I can work there when it's raining. It's 2 x 4 construction, 1/2" plywood on the outside, 1/4" on the inside, shingle roof, fully caulked and insulated.
I built the floor, walls and roof in my garage and assembled it on I site I had prepared next to my guinea fowl pen. If anyone asks, I tell em it's a brooder box for the hens. I had electricity running to my fence, about 20' away so just dug a shallow trench, laid some conduit and I had juice.
Inside I have a 4" fan hooked to both a variable speed controller and a thermostat. A small electric heater, also on a thermostat. For light I'm using a 600 watt HPS. It took a little while to get the temperature control dialed in, but now I'm running about 82-84 lights on and 74-76 lights out. I installed a remote temperature sensor so I'm able to monitor my temps from the house.
I'll be finishing up my first crop in another week or two. Six Onyx and 2 Auto Assassins. They got off to a rough start till I got the temperature control figured out but are looking read good. I'll be able to do one more grow before the weather starts to get too warm. I'll shut it down for the summer but will start it up again in the fall, soon as the weather cools. I'm hoping to do 3 crops a year of either 9 three gallon pots or 12 two gallon pots.
Total cost was about $700 but I already had the light, reflector and ballast. I did all the work myself, including the wiring. It was a fun project and I'm enjoying being able to pursue my hobby during the winter.
