Our mission
Craft cannabis, thirty feet below the shop
Beneath our dispensary sits a pharmaceutical-grade grow built from the ground up — PVC-walled rooms that resist mold and mildew, predatory mites flown in instead of pesticides, and LED lighting that simulates Nantucket sunrise and sunset.
A small, pristinely curated facility means every plant gets the attention it needs to reach full maturation. The result is the highest quality craft-grown cannabis on the island.
