GH365 Greenhouse Production through Severe Winter.

The winter of 2013-2014 has been a real challenge for many of us. In this region of Northwestern Ontario, we've had record low temperatures frequently in the minus 30s for a period of well over three months (December, January, February and early March). To compound the problem with my GH365 Greenhouse, we went through periods of little sunshine and yet consistently low temperatures especially at night. Nonetheless, the greenhouse has shown excellent heat retention values and most of the vegetables and herbs survived although in some cases slow in germination and growth. The following photos were taken on Friday March 7th. At that time of morning the outside temperatures were around minus -21 Celsius and the inside temperatures were at + 5.4 Celsius increasing to +9.5 Celsius by mid-afternoon. From top to bottom are -- Lettuce, Broccoli, Peas, Tomato, Oregano, Rosemary and Wheatgrass.
