I put some camo netting over it in late July for some of the stuff looking a little frazzled from the sun/heat. just turned out that way from some high soil I leveled out.ġ0X20 tarp shelter fit right over it. Just so happens, I have a raised bed garden about 9X19. I am in the southern Willamette Valley in western Oregon - "the pacific north-wet".Ībout ten years ago my sister was throwing out one of those tarp garage deals that you see everywhere, all busted up. OK, I know this is an old thread, but I can't skip playing! If you went into a desert property and tried to force it to grow tropical fruit without adjustment, would you blame the property for your failure? A greenhouse is no different. The "suck factor" isn't greenhouses as such-it's the cookie-cutter greenhouse designed for cold climates and aristocratic playtime. Anywhere else it has to be modified for the location. The glashaus to collect heat works well in the far north, or areas where it seldom gets above 60 degrees. If I got the chance to move to a larger place I would certainly be building another-site specific, and entirely passive. I have learned a lot in the building and use, so any future greenhouse would apply those lessons. An eco system is gradually developing, making pest control a non-issue. It does freeze a couple times a year, but that's a design flaw I think. It's never frozen inside after March 1st. The first frost date (barring any unseasonal freeze, like last year when it hit the teens in September and I wasn't expecting it so the doors were still open) is the end of November. In five (?) years of measuring it has never gotten below 20 f and only reached 20 when the outside temperature was in the single digits. During the winter the sun hits the front wall straight on. The roof actually faces north, so even in the summer the sun doesn't hit it directly. It has a door on either side in the direction of the prevailing winds so on the hottest days it's seldom more than 5 degrees above the outside temperature. It's small, passive, built into a hill for additional thermal mass.
