Looking for a way to grow your fruits and veggies all year round? There are many advantages to using a geodesic greenhouse to extend your growing season!

When choosing the location for your greenhouse, try to pick a sunny spot that is protected from the wind. While a base isn't required, we strongly recommend that this greenhouse be anchored to the ground (floor/cement) with included anchoring plates. Anchoring hardware will need to be purchased separately to best suit the ground type of the location it will be installed on.
