Pacific Northwest Gardening: How cold does it get? Your greenhouse, that is., 1 by

I have a glass greenhouse and after several years of insulating with bubble wrap last year I sprung for double wall polycarbonate sheets, had most of them cut to fit, which is very cheap to do, and now the greenhouse stays very nice and toasty without a lot of fuss. I have several heatmats on shelves and they give off a gentle radiant heat that keeps the greenhouse close to 50 degrees without extra heat until the really cold part of winter. Then I have a portable electric heater that I keep on low. It has a thermostat so I can regulate the temp. It also has a fan that keeps air circulating, which is very important in the winter.
I bought the polycarb panels at a plastics supply house in Tacoma and they were Really cheap compared to Charlie's greenhouse, or any other supply with the word 'greenhouse' in the name. My greenhouse is 8 x 12 and I was able to completely retrofit it for less than 300$. It sounds like a lot of money until you see my utility bills from the winters before. Shudder.

If anyone is thinking of buying a greenhouse, especially from the highpriced place up north of here that starts with a C (which I referred to earlier in the post) might I recommend checking out BC Greenhouses first. I ordered mine from them directly. They manufacture the same greenhouses that are sold retail at the expensive places here. I saved several thousand dollars, yes THOUSAND, by ordering directly from them. The greenhouse kit arrived on a truck and my dh and I put it up in 2 days. Their customer service is excellent.
