Whoa, talk about drastic losses, glad you at least kept the family warm, Sway. But . . . let me gently chastise you for not getting on to the rest of us sooner! We could have had you up and recovering a month ago.
That's what gardening friends are for - Plant insurance and depression recovery.
Another suggestion, against a future failure of greenhouse heating - my old buddy in Utah says he now keeps an old bathtub he got from the Re-Store in his greenhouse. Puts in hot water on the coldest nights and it helps humidify, as well as provides a very large heat sink. They didn't have a drastic winter there this year, but he tells me his greenhouse never got below 40deg. (he's the guy I've told you about that used to use the plastic storage tubs as his greenhouse heat, with waterbed heaters in the water only used on the coldest nights)
So, put the word out to your friends and neighbors locally - if anyone's doing a bathroom renovation you'll come and haul away their old tub for free . ..
