Greenhouses

Greenhouses and coldframes are great options to raise the ambient temperature and allow you to grow in frosty weather, get a jump-start on your seed starting, or shelter delicate plants from the elements. Choose from our selection of coldframes, greenhouse plastic, or beautiful redwood greenhouse kits.

Regulate temperatures in your greenhouse or coldframe with automatic vent openers.

If you are building your own greenhouse and need plans, or just want to know more, check out the DIY books that are our staff favorites.

FREE SHIPPING on Greenhouse Kits and any accessories that are ordered at the same time as a greenhouse to the Continental US!
