Exactly, so if you are in the City of Phoenix you must have your offsite grow in an industrial area. Either A1 or A2 zoned, you can only have 1 grow location, and it can no be the same location as the dispensary.
If you wanted to have even 10 strains which I think would be minimal for a good dispensary, I'd rather see 12 -20 choices, maybe some staples always in stock and some flavors that are seasonal or rotate. So you would have anywhere between 10 to 25 mother plants alone depending if you have 1 or 2 moms per strain which would be good.
So there is no way you could remain under 100 plants at the only offsite grow location allowed and have enough to supply a good dispensary with 10 to 20 flavors on hand at all times.
