Our History

Created in 2012, GRO, is a 21+ Medical Marijuana in home delivery service. Originally formed by a small group of growers, we were previously a group of friends who grew for each other and we were members of a small private collective.

We believe in providing quality medication at a reasonable price. Our In House growers are our original founding members. Using their combined 30+ year knowledge and experience, our growers produce all natural, organic medication from their small boutique operations. Our craftsmen and women take the time to attend to each plant, allow the plants to mature naturally, and take extra care in preparing medication. No chemicals, pesticides, or artificial colors or flavors are added. We also believe in lab testing all our medications, to ensure the highest quality possible. We are careful about how we grow our medicine and what we offer to you, because we use it ourselves.

Our corporate secretary and our CEO both operated USDA and FDA inspected food plants so they are fastidious about the cleanliness of our grows. This is important, since some of our members and friends have compromised immune systems.

At GRO, we offer a wide variety of cannabis for everyone’s medical needs and budget. We really listen to our members and we help them tailor solutions that optimize their health and happiness.

This page is Intended for California residents, 21 years of age or older, with a valid California ID and a valid doctor's recommendation for Medical Marijuana.
