Vendor Guidelines

Starting January 1st 2018, The REEF exclusively accepts cannabis products from legally licensed manufacturers and distributors who are cultivating in accordance with Michigan law and have a copy of their license.

Regulations require that vendors enter through a different door than our customers. So please note that there is now a vendor entrance located on the back of the building.

If we do not accept your products the first go-around please don’t be discouraged from trying to sell us your products in the future. He use the highest of standards when it comes to providing our customers cannabis products, please feel free to try more than once.

As you know, the cannabis industry is an ever-changing market. Therefore, we choose not to suggest any specific strains to grow. We would hate for you to go through all of the genetics, flower, cut, and cure, to end up looking at a different market..
