Geodesic Dome Greenhouse - Part 9 - Polycarbonate!

The dome is now covered with polycarbonate! It's nice to be able to work "inside". It's still cold but at least there's no wind! The aquaponic system is right around the corner!

6mm twin-wall GE Lexan

I watched all of your dome videos and they're awesome. Now i'm watching all of 'em again because i'm planning to build one myself :). Just wandering what angle you are cutting the wood for the polycarbonate to lay flat?

[web4deb]

@Krissappleseed for a 3V dome, around 12 degrees would work. Technically there are a lot of angles, but overall the average is about 12.

[khoiktran]

will you give us the total building cost of this project? I did some quick calculation and the price is really high.

[web4deb]

@khoiktran I don't have an exact amount but it will be around $25K

Hey, I just watched your aquaponic carrot video but needed another geodome fix. I was thinking at the hubs you could have another larger version of the neoprene washer, maybe homemade, over that hole, held by a threaded rod to the inside and a threaded washer or piece of metal spanning the hub. Just a thought. At least you weren't out there today at 10 F or were you?

[web4deb]

@NewEnglandgardening I'm not too concerned about the holes through the hubs. All the poly carb panels come to a point over each one. This spring I'll use my special tape and cover all the joints...it will seal up nicely. I"m NOT outside today....I had to go to my real job anyway. ;-)

I can see how some wind would have made it take many times longer.

Can't tell you how much I appreciate the spirit in which you share every step with us, every success, every OOPS and unplanned speed bump...

This has been the most easy to follow construction project of geodesic domes on the internet. Thanks for having the confidence to attempt this, you are both good at doing and showing. Perhaps I will attempt this on a smaller scale, if I can find the plans you worked from. A Happy and Holy Christmas brother. Blessings from Ireland.

what size polycarbonate did you use? 

[urbanstarprepper]

Awesome job!!!! I have just built my first dome I made it out of 1/2 in emt conduit and 3.5 mil plastic. this is so I can disassemble and move it. when we finally get the piece of land we want I am planning to build one similar to yours.

[ibringthereals]

Massive effort. Great work. Has me wondering whether a two layers of 6m plastic I use for high tunnels would be more cost effective if not a better insulation when double up with an air pocket between. The greenhouse grade plastic is good for 4 years, and simple to replace.

[viscon2011]

@web4deb hehe there must be something cheaper than polycarbonate but still reliable.

Hurry up with part 10! The anticipation is killing me!!!

[camomantube]

grate work i can't wait! to see more videos keep it up
