It truly depends on what license you have. If you have a Personal Medical Marijuana Card or Business Medical Marijuana Card or Growers Medical Marijuana Card your “contract” should state the maximum number of plants you are allowed to grow per cycle and month. My Grower’s Card says I can grow up to 6 plants per cycle stage and no more then 24 plants a month. I grow for personal and non profit (I give away to patients who can’t afford on their own on). It took a lot of planning and had to have my Personal Card for 2 year without a violation to get be able to do so. When i was growing from my Personal card alone I was allow 9 plants total a month and only 3 per cycle stage. You can grow to your hearts content with a Business Card you just have to pay a tax per plant at the end of the year. There is an option to grow unlimited number of plants with a Business Card that you are taxed like any other business (profit/loss) but that is a pain in the ass and not worth it unless you have about $500,000 start with (these licenses are for the business “farms” that sell to major dispensaries world wide only 2 legal “farms” are based in the US and only one is in California).

PLEASE REMEMBER!!!!!
That just because you have a California MM Card you CAN NOT use it outside California. If you plan to travel to another state the has it as strictly illegal you will be arrested (Federally it is still considered illegal and they have the right no matter what you say). If you plan to travel to a state that DOES have legal Medical Marijuana check with your doctor to see if you can get a temporary License in that state (you have to still pay but can buy and smoke worry free), State to state differs on what they view as Medically necessary and you might not qualify.
