Yep but as far as local laws go.....if you are in CA. and have a med license to grow based Senate Bill 420 as a general guideline (SB420) then you can have 1 mother plant, 12 immature plants, and 6 mature plants.
So if you kept within those limits you shouldn't have to worry about feds crashing down on you. Not sure how that would work if you are part of the dispensaries bigger picture, but yeah if it sounds to be good to be true then it prob is. It is hard enough to try and sell a TV on CL without getting some sort of spam or scam. lol
All that being said if you live in Ca. and set up your own grow the local dispensaries will have no problem paying you....or should I say donating towards your cause to provide free medicine to their patients. Also keep in mind they shut down all the walk in dispensaries in South OC, Central OC (Santa Ana, Orange) are being shut down this week....Long Beach done and now it is just LA not sure how Riverside or Inland Impire is working it. Delivery service is still going strong though....
