Hi, guys! (This is a repost, couldn't find the previous one, maybe did not press finish)
I am planning to build a very small greenhouse (20 ft x 5.5 ft) in my backyard, facing mostly west and south.
I have been doing serious research on "GAHT" system over the past weeks and seen all the St. Isidore/Cerese/Verge Permaculture etc. videos on youtube on this thermal system. Also, I've read the ecosystem design faqs, ceres and verge permaculture info, also got their calculator. The most difficult part was converting form imperial to metric, as I live in Techirghil, Romania.
I intend to do the system myself, with help from local Phd shovel diggers. I think that ceres price is not ok for a system like this. It is a matter of principle, not money.
So, as I want to plant mostly tomatoes, peppers, zucchini and other vegetables and maybe a lemon tree and avocado tree.
Luckly, my climate is very similar to Mike's, in Easton, PA.
Based on Mike's very honest feedback on the "Gaht" system, I have big concerns on the efficiency of this system during winter, for a vegetables & fruit greenhouse.
I recall that both Mike and another forum member said that tomatoes are not able to grow during winter.
So, is the Gaht system efficient during winter? Or is it mandatory to help it with a more "traditional" heating system, for growing vegetables and fruits?
Thank you in advance!
*hope I did not missspelled anything
