A great way of extending the growing season or getting a jump on the garden is by using a cold frame. But are you aware that a cold frame and hotbed is the same thing? If not, come join me in the world of cold frames, hotbeds and sustainability.
Whether you are talking about Outdora’s Redwood Cold Frame Starter Box Greenhouse or the Solexx Deluxe Cold Frame, the general definition is the same. A cold frame is solely heated by the sun and is normally used for cool-season or Cole crops. A hotbed is artificially heated in some way and is typically used for warm-season crops, such as tomatoes, peppers, and eggplants.
Both of these structures can be directly planted into or seeded flats can be placed inside each. To maximize the amount of sunlight that is typically available during the spring and fall when these structures are used, the cold frame/hotbed is normally painted white or silver on the inside. Both of these colors reflect the light back onto the plants, which aids them in the photosynthetic process.
