the way i figure it, spending anywhere up to $1000 as an initial investment would be worth not having to buy ever again, or at the very least rarely. plus right now i can normally only afford high mids, so i'd be looking to get some really nice stuff growing. if i smoke about 1-2 ounces a month, how many plants would i want? how many ounces per plant (estimate)? how many plants would i want? and how much space would i need?
