Generally speaking if you live in the northern hemisphere that puts delivery at spring time. Not a bad time to build your dome. Otherwise it would be fall, also not a bad time to build.
Good luck with the dome and keep us posted, with photos, of the build.
Are you automating the dome during the initial build?
It's on its way! Took 9 weeks. Not sure how long it will take to cross Canada and go south to Virginia but it has been shipped! Horray!
I was just notified tha delivery will be in 8-10 weeks.
Mine took months but that was 2018. Have you reached out to ND for an ETA?
