Testimonials

I couldn't believe how knowledgable and how quick the customer service was. GMS caters to individual needs, I will be a long time customer!

Fred F, Squamish

Frank from GMS was very knowledgable and walked me through how to use each product I inquired about, and even sent me some great links after our conversation to make sure I was comfortable with my purchase. I highly recommend GMS to all growers alike! Five Stars!!!
