Even if it is cheaper to buy weed I just don't like the idea of it. I do buy because right now that's my only option but you're going to have to pay for your electricity anyways. Bills are one thing, but spending that same amount on an ounce of some high grade weed is another. That house should last you for as long as you can maintain it but that bud you paid for will be gone eventually. It's as simple as that. Everyone that enjoys weed like me should be growing it IMO.
