Where I am in CA, you can't buy more than an ounce but you can grow six plants as long as you use just for yourself and/or give it away.
I came in under medical (I have glaucoma) when eighths were $50 and up. I went to the DT Seattle dispensary this year and it's about that.
Suffice it to say growing is more economical. Especially if you are medical and somewhat broke but still have a place with some land, I can't see how it's not the better option.
Is this legal there?
