Our Suppliers & Partners

Nanticoke cannabis flower products are greenhouse grown in Endicott NY. Our team of growers combines decades of greenhouse growing experience and it shows in our final product.

Our Growers & Processors

Our growers and processors come from all over the state of New York, from the Southern Tier to the Upstate. Many of them are small businesses and family farms, who put great care into everything they do, from seed to plant to finished product. 

Our products come from brands like Ayrloom, a 5th generation family farm that combines over 110 years of agricultural experience with a passion for cannabis culture. Another of our growers, House of Sacci, cultivates their plants in a 40,000 square foot greenhouse, producing some of the finest flower products in New York.

Our relationship with our growers and processors keeps us connected to our products. We know the care and craftsmanship that go into every item we sell, so you can feel good about what you buy.


Every product that you buy at William Jane must be made in the state of New York in a controlled environment using sanitary practices, and then be lab tested for quality and safety. These rigorous tests performed by state licensed laboratories include screening for microorganisms, pesticides, residual solvents, heavy metals, mycotoxins, terpenoids, and more. Lab testing ensures the accuracy and transparency of product labeling so that you can make informed decisions about the products you are consuming.
