This chap wrote a book. I ordered it last week, but I can't comment as amazon says it'll take another two weeks to get here. I just built a hybrid (well, bigger than a cold frame and not a full size greenhouse) last weekend. It will be unheated. I've looked up some information on the internet regarding greenhouses, as my sweatheart has a strong interest in veggie gardening in winter and the accompanied financial benefits, specially during winter. There seem to be two schools of thought: using heated greenhouses and unheated greenhouses. For starters I made this small thing, 2,5 by 1,5 metres, about 1,5 metres tall, both roofs sloping. Sadly its burried under one and a half feet of snow today ... winter came in early this year. Next year I'm planning a bigger, walk in greenhouse. It'll be unheated, as we don't aspire to tomatoes in winter. This year we got salad greens in the "hybrid". I'm quite confident it'll work fine, as in the previos winter our winter lettuce survided quite nicely under more than 2 feet of snow just covered with gardening fabric. But that was just surviving, not growing. We're hoping for more with this new setup. _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/sustainablelorgbiofuel Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (70,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
