Hello I was thinking about purchasing a geodesic dome Greenhouse online but the prices seem ridiculous IMHO so I done some searching and found this beautiful site here. I would love to build one this spring. I would like it to be between 20-25 feet in diameter as be able to handle the weather here on the bay of fundy in new Brunswick Canada. I have no idea where to start. lol 2v, 3v, 4v etc I have no clue where to begin. I would prefer a polycarbonate glaze n for it to be sturdy as well as have room for a door n some vents on the top. I have roughly 8000.00 to sink into this project but would like to make it as cheap as possible. If I left anything out please let me know. Thx in advance folks!!
