la county the id and expansion stamp. (its a stamp i found out by the way dan). kinda like a donar stamp on your liceance
but it allows 99 plants in la county. i can only grow 50 in kern county but its ok . and odds are there only gonna extend
your possesion limit to the full p 16 oz. they dont really want you smoking than more a g a day. sorry but to really answer your question, ask your doc and pay the 25 dollars, your standard limits will be 12 plants TOTAL, 6 mature, 12 immuture, and your allowed 8 dried oz of cannabis flowers, the id will not extend you limits of cultivation, tell your doctor you smoke a shit load and need to grow a years worth. then you will get your limits streched
