insulating a greenhouse
I have a poly type galv frame greenhouse around 24x12. Im looking to heat it mildly to overwinter some plants. Any ideas on insulation ? Thanks-Josh

Insulating a greenhouse
If using an electric heater, make sure it has a temperature control so it automatically turns on and off. Make sure your greenhouse is 'tight' -- no cracks around doors, vents, parameter around the balcony, etc. A small leak will let a lot of heat escape. During winter, you can line the inside of your greenhouse with 4-mil polyethylene film. Double layer is better and can reduce heat loss up to 40%.
Other things to save heating costs:
Keep greenhouse cool at night - don't heat above 50 degrees. Grow plants with low temperature requirements or short growing season. For germinating seed (must maintain 70 degrees) build a small propagating bench with cover to keep warm. Solar heat storage -- add water filled dark drums or other material to capture and store heat during the day and release it at night.
