Re: Looking for a 4″ solar fan for my greenhouse.

18′ diameter geodesic dome made out of 2×4’s and 6 mil greenhouse film. Insulated foundation, thermal pond, and the aforementioned underground heat system. Plans to incorporate a solar thermal collector to heat the pond. I don’t know how to upload pics but you can see all my progress at https://geogrow.blogspot.com Since early last winter I have documented my construction and it is now starting to look good! I hope you check it out and like it…
