Do I need a heater in the winter?

Well this depends on where you live. Greenhouses 4 Less is in Southern Tennessee and heaters are not needed here. When the weather gets cold the sun is still generating heat inside your greenhouse. In fact on a cold day in the low 30's the heat generated from the sun through the plastic covering on your greenhouse will keep a temperature in the 50's. Even thought out most of Tennessee or states in the surrounding areas greenhouse properly installed do not need heaters. As you go further North most people use a double layer of greenhouse plastic and use a fan to blow air between the two layers. This creates an insulated barrier which helps keep your greenhouse above freezing on the inside. We always suggest to our customers that they monitor the temperature in their greenhouse before spending money for a heater. This is of course assuming your greenhouse is getting plenty of sun during the day.
