Legally growing in CA?

My friend was telling me about a grow license for up to 400 plants. Something to do with arranging the grow with a club, but not having to sell the bud to the club? Just looking for as much info on this as possible.

Here's another one! ahahaha

....check out NORML

Best explanations I've ever seen! Such helpful people...

Im not a vendor so I dont know how you go about becoming legit, however I do know the information is on CA NORML's website....so go read about it

Thank you.
