Would I be able to sell concentrates to you guys?

No. There are a range of requirements that must be met before you can be given a Florida Marijuana Growing License. These are; An applicant’s nursery must be at least 30 years old and should also possess at least 400,000 plants in cultivation. The applicant should prove that they can manage the huge start up expenses which is approximately $2 million and the bond needed for your medical marijuana dispensary to be licensed. They must also demonstrate to the licensing officials that they have the ability to finance their business for at least 2 years without going bankrupt.

They are self efficient. Producing there own product

I don't work there. But they make their own concentrates from what I understand.
