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.
