Geodome greenhouse progress

Monday, May 22nd, 2017

Projects here seem to have their own timing. What seem like frustrating delays at the time have an uncanny knack of turning out to be necessary pauses: intervals which allow for much better solutions to emerge. The geodome greenhouse has been no exception. With the groundwork complete by the middle of last summer, I was hoping to have it covered in time for winter. This wasn’t to be. My fault mostly. I wasn’t happy with the lack of solid UV resistance data and guarantees on clear PVC and went off to ferret out something more robust. Several lengthy explorations into such materials as ETFE and polycarbonate later, it was clear that robust was beyond budget-busting, so in the end I came full circle back to the PVC.

But during the delay, two things happened. One of the suppliers we were in contact with listed a new high transparency UV-treated PVC film. And Liam acquired a high-frequency PVC welder. I’m sure neither of these facts will mean much to many, but take it from me: the end result is just so much better than it would have been had neither of those two things happened.

The greenhouse cover is now almost complete!

Geodesic dome greenhouse

Back in July 2012 we dug a chunk out of the mountainside in preparation for a ferrocement rainwater harvesting tank. Plans for the tank were later shelved due to budget constraints, but a good use for the site was never in doubt. It’s one of the few parts of the quinta to have sun at winter solstice, so was perfect for a greenhouse.
