Within the next year after funds are collected me and some friends have gone ahead and agreed to do a secret underground grow room. Our goal is about 10 to 15 pounds per month. My question is how big would the basement need to be overall with a one veg room, two flower rooms, supply room, and prep and drying room. Sounds crazy but my fav motto is if you just put your mind to it nothing is impossible. Budget is around 40 to 50 grand. the room will be located under a garage with hydraulic lift to a smaller room with vault door access to grow room.
