Two medium-sized greenhouses at the top and bottom with the text in middle saying: Medium Greenhouses for hobby gardeners - 65 to 150 square feetWhat is a medium greenhouse?

Our medium greenhouse collection contains all greenhouse kits with 65-150 square feet. Here you will find all brands that we sell with FREE SHIPPING to the continental U.S.

How to pick the right greenhouse size?

We always give the tip to buy one size larger than you planned. Not because we want to make more profit. No, because most of the times our customers regret to buy a greenhouse that is too small. So be smart and think about the plants you want to plant before purchasing. However, some of our greenhouses are extendable, so you can also start with a small size and upgrade later on.
