The main goal of greenhouse gardening is to provide a controlled environment.
In a moderate climate, the best choice for keeping a greenhouse above freezing is a small electric heater.
For larger greenhouses or small greenhouses in cold climates or those requiring a hot house environment, we would recommend electric, propane or Natural gas heaters. The capacity is dictated by four things:
- the cold outside temperature at night
- your desired night time minimum temperature in winter
- the surface area square footage of the greenhouse
- what glazing you choose
We have a formula that provides the heating requirements for your greenhouse. Contact one of our greenhouse experts today to talk about your growing needs.
Tip For Orchid Growers – backup generators are common or gas heating in the event of power outages. Portable camping heaters are also used in the event of power outages.
