Heating a greenhouse within the cooler months can often be quite daunting. In fact, it may require a great deal of patience and perseverance to get it right! For those new to the world of greenhouse growing, we recommend using electric heaters as they’re easier to put in, more economical and have a wider range of applications. Usually, a little 120-volt heater will heat a relatively small greenhouse just fine, while larger greenhouses will need a 240+ volt heater, controlled by a reliable, waterproof thermostat. For the eco-minded people in the world out there, less energy-intensive forms of heating include fixing ventilation systems which use unneeded warm air from your home. This is a great option if you’re looking to save money right from the get-go, but it’s best to use an electric one to begin with, as it’s easier to get the optimum temperature for your greenhouse.
