In bloom this sunny, frigid morning. Down to -30F wind-chill last night, but we were able to maintain a greenhouse temp of 57F. Really glad we decided to over-size that Modine heater! Temps are forecast to moderate by the end of the week.

Thanks Tom,The natural gas-fired Modine heater output is 75,000 btu/hr. If I remember correctly, the heater was sized for a delta T of 70F ? (If outdoor ambient temp is -20F I should be able to maintain 50F in the greenhouse).
