THREE-SEASON GREENHOUSE KIT - FAQS

1) Can I Upgrade my Three-Season Kit to Four-Season?

Yes. These kits are designed so you can add insulation and a heating source to extend them into a four-season structure to grow in Canadian winters. We’ll advise you on the best options for your climate and how you want to use the space.

2) Is this Three-Season Greenhouse Kit Available for Pick-up Only?

If you would like to purchase a backyard kit but are unable to pick up, please email us at info@greenhouseinthesnow.ca.

3) What do I Need to Source Myself?

Your kit includes everything structural — the steel frame, polycarbonate panel, screws, and step-by-step installation instructions. You’ll customize your greenhouse by selecting a door and metal siding that matches your aesthetic preference, assorted lumber, and, if you’re going four-season, a heating source and insulation.

You benefit by sourcing these remaining items local-to-you, saving significantly on shipping, while supporting  businesses in your community, while getting to choose finishes that actually match your home and property. Want a barn-style door? A specific siding colour? Done. No two Greenhouse in the Snow builds look exactly alike and that’s the whole point!

We send you a detailed shopping or sourcing list with specific recommendations so you know exactly what to get and where to find it.

4) How Difficult is it to Assemble the Greenhouse?

Our kits are designed for Do-It-Yourself assembly. Most backyard kits can be built over a weekend or two with a helper. Detailed instructions are included, and the Greenhouse in the Snow Canada team is available if you run into any questions along the way.

5) Can this Three-Season Kit Handle Canadian Winters?

As a three-season structure, this kit is designed to extend your season significantly beyond open-air gardening due to the strategic design and positioning the greenhouse to capture the most sunlight. With added insulation and a heat source, many customers are able to use them year-round. We’ll help you assess what’s optimal for your specific location and growing goals. 

From a structural standpoint, absolutely – your greenhouse will stand tall against the harshest snowstorms.
