A greenhouse is a severely underrated space for gardeners in winter. On its own it provides coverage and protection from frost for cold-hardy plants and crops, but you can instantly double its use by adding one key tool: a greenhouse heater.
Heating a greenhouse allows for a number of winter greenhouse uses, including growing plants from seed and overwintering tender perennials. This Air Choice greenhouse heater with a digital thermostat from Amazon makes this effortless to do, even if you only have a smaller portable greenhouse.
