This webpage has all of the info you need to figure it all out. The search feature is your friend and there are many detailed grows here to emulate.
IMO...it is doubtful you will find a private grower who will let you come into their space/garden/life. Legal as it may be (seem), everyone is still taking a risk growing this plant here and individual actions will likely reflect that. (note the lack of response for proof) Keep in mind, most folks just go for it and get schooled on their own time/expense/in their own locale before heading here.
Ditto that for the med industry. Experience will be key...especially in the feild of getting used and abused. You may also want to check out the State residency requirements here as well as the invasive forms you are required to fill out for the State to be entitled to work for minimum wage in the medical cannabis 'industry' here. :eek: Seems like there were a bunch of 'em...
good luck
