Our friendly staff  welcomes all gardeners - from the most experienced to beginner gardeners who aren’t even sure where to start. Whether on the phone or in person, we take the time to listen, to truly understand each customer’s gardening goals - before suggesting useful tips or products. Our associates not only have factual knowledge of gardening products but also have years of experience from which to draw upon.

Shopping at GYO means eliminating hours of research and guesswork trying to find the right products. We strive to stay ahead of the curve in indoor, organic and hydroponic growing, so you can trust we offer only the finest grow technology.

Unlike our competition, we never buy liquidated inventory or old, deeply-discounted, soon-to-be-expired nutrients. We receive new products every few days, so when you buy from GYO, rest assured you’re buying only the freshest nutrients, soils and seeds.


We are constantly adding new products to our inventory. We offer the absolute latest in Light Emitting Ceramic, double ended, and LED lighting, as well as a wide range of other trendy items such as Boveda Cure Packshomegrown CO2 and Method Seven sunglasses for HPS-lit grow rooms. One customer of ours commented, “You guys have the stuff that’s been around, but then you also have that new stuff that I see in the magazines.” Yup, that’s the idea. It's no wonder why we were voted the Best Grow Shop in Boston!

We offer a wide and rotating selection of monthly sale items. Items as sought after as the Grow Flow Ebb & Flow 12-plant hydro systemHouse & Garden’s premium nutrients, our best cloning machines and much more.
