Backyard Greenhouses perfect for Northern Growing Climates

Imagine starting your summer seedlings in a dedicated greenhouse instead of on your kitchen table or in your basement!

If you dream of growing ripe tomatoes in the winter, curating your own collection of tropical plants, creating an outdoor sunroom, or enclosing your hot tub - look no further!

  • Taller and made with thicker wall panels than others, the Riga and Royal Victorian Greenhouses are available in multiple sizes.


  • The Royal Victorian comes in green or black aluminum and with glass or polycarbonate (recommended) panels.


  • The XL models of Riga greenhouses feature triple wall polycarbonate panels that protect plants from the cold.  


  • Optional accessories available to customize the interior layout for personal preferences.

"In general, an unheated greenhouse lets you grow plants rated for about one USDA climate zone warmer than our local area. This translates to about five to eight degrees Fahrenheit. Another way to think of it is that you'll add two to three weeks on each end of the growing season. But if you provide supplemental heat and light in the greenhouse, you can grow any kind of plant you like." - Roger Marshall, The Greenhouse Gardener's Manual
