► Heating the Greenhouse:  

 Heating the greenhouse is certainly a huge task when subfreezing temperature exist.  The greenhouses posted on The Pond Plant Girl Show are designed as temporary structures and are not effective for cold climate zones.  Because of the sever weather and heavy snow, a more permanent solution is required.  A simple wood shed with double pane ceiling windows is a perfect way to get a jumpstart on the season.  Heating a greenhouse with a wood stove might not be worth the expense.  A waste oil heater is a more economical choice.  This heater is not recommended for use in a small area greenhouse or in a plastic sheeting greenhouse.  Excessive heat can spark a fire.  If constructed and installed in a small area, I recommend a concrete, dirt, or brick  floor.  Aluminum siding should also be installed on the walls adjacent to the oil heater and possibly on the ceiling to prevent fire danger.
