Please check and support the project of greenhouse that requires no heat in winter and will never overheat in summer:

Paul Wheaton and his permaculture team plan to build it and share the whole process, even documenting the greenhouse’s performance through an entire Montana winter.
And if you support them on Kickstarter, you’ll get gobs of amazing goodies related to permaculture, homesteading, and gardening--even if you only give them one dollar! https://www.kickstarter.com/projects/paulwheaton/greenhouse-1?ref=xgzvjj
