It's hard for me to imagine growing cannabis in an effort to make money. I have learned from what little experience I have legally growing, it is a lot of work. If I were dong this as a business I would NEVER be able to charge adequately relative to how much time it takes to maintain a garden, research, etc vs how much I feel my time is worth.
Sure, if someone grows "weed" I am sure it may make $ense but, growing something that you pour your love into is time consuming and I can't imagine parting with my handcrafted meds.... How would I put a price on it! To me it is priceless, a product of my love, fun, research, engineering (room), etc.
so, for those of you growing medical grade cannabis to help your patients, you have my respect because you are underpaid....
