I live on the west coast in the pnw. It snowing right now. I was thinking of building a grow box that 8 feet tall and 4x4. With drain to waste system with 9 3 gallon coco coir in airpots. Hope to veg for 2-3 weeks. Top once. Lst and hope for a 12 oz every harvest. For a light I be using a 315w cmh with 3100k Phillips's bulb. I might need to buy a heater in to put in there.
