Spring is coming!

The bubble-wrap insulation on the greenhouse walls worked like a charm! Propane consumptions was drastically cut. Last year I had to refill the propane tank 4 times; this year it is still running on the first tank from November, and looks as though it will make it through the next few weeks into real spring weather without having to refill. What a coup! The cost of the bubble insulation was recovered in a single season!

Greenhouse Update

From what I've read in various sources, it sounds as though I should put reflective bubble insulation on the North wall and the wall facing prevailing winds (in my case, the West wall, and clear bubble insulation on the other walls. That's what I'll try, and record my success here.

I'll reuse the reflective insulation from last year, but have to order clear insulation. More $ out the door now in an attempt to save $ in the long run.
