First wow. First look at this forum, layout is serious ADHD. Take some learning to get through pages. Been looking at lots of geodesic greenhouse styles. Plastic, wood, metal conduit. I want to build a geodesic lean too style greenhouse on to a brick wall. Can someone direct me to a good location to understand the process on this? I've see the dome calculators, but 3v 4v really? The calculators I found didn't explain or educate the neophyte before they expected numbers dropped into a formula. Any help appreciated on this. I really want and need to build an excellent dome. Thanks
