Hobby Greenhouse Growers Exclusive Offer! Get 5% off any custom built Maine Garden Products greenhouse when you mention our name.

This offer is not available anywhere else!

The Mainestay Greenhouses are constructed from Eastern White Cedar for a long life without the need of treating or staining. The vents are fully automated with Danish made thermo-hydrolic openers. The triple wall poly-carbonate glazing insulates and traps the heat inside to extend your growing season! Our 8 foot wide model comes with a generous 30" wide door for easy access with wheelbarrows and gardening tools. The 10 foot model comes standard with 2 - 24" doors.

The mainstay was designed specifically with ease of assembly in mind. The simpler design makes it an ideal project for a do-it-yourselfer, and it is able to ship anywhere in the US.
