Hola. I think it's too risky unless you put a lot of effort and time into making them blend into the existing landscape. The 3 in bloom would be limiting factor as well because you could only grow 3 per season here in Denver. Most of the clones you can get here in the mile high are mostly indoor strains which may not do well in our summer photo period. Then there's the bugs & thugs that want to get at your babies like rats. You can spray for the bugs, but i'm certain I do not want a thief trespassing into your garden, unless you want to combine target practice with horticulture.
I think that the price of meds would go way down if the state allocated 10 acres parcels to experienced outdoor growers to grow acres of quality mj. Then the state could sell it to the dispensaries for a huge profit after taking care of the farmer with a % of the overall sale, and then tax it again when it sells!
I've rambled on long enough. Peace and Purdie
