Parts On Order.

This week I ordered the final assembly parts for the dome greenhouse. We got the 8mm polycarbonate panels a good while ago and then got busy with survival things like solar installation and drinking.

To put the panels onto the dome takes either a willingness to do regular maintenance or a commitment of capital for maintenance free parts. We almost always elect to work overtime and buy things we won't constantly have to mess with. It tends to leave more time for important things like gardening and drinking.

So I went here:
to get "H" channels, "U" channels and neoprene washer installation screws. They also sell the 8mm Polycarbonate. It was a significant chunk of change but the idea of having to scale the outside of the dome every few years to reinstall greenhouse taps to the seams irked me.

They have a bit of a lead time, not scheduled to arrive until about 3 weeks after placing the order but we always have plenty to do, so why not?

This left the question of how to properly weatherproof the hubs (where the polycarbonate sections come together). What we settled on is to purchase enough round electrical box covers (steel) with a center hole and a 4" diameter and put cut up yoga mats under them for insulation and to stop air/water ingress/egress. The inside of the plastic hubs we used for assembly have a center hole so I can use a 4" bolt with appropriate washers to attach them. I think it'll work well.

The nice place, Gempler's, that I got the channel from does ship by truck, and often has a coupon to save 10% to 15% off their already decent prices.

I also ordered a couple of temp activated vents to install. With our rather impressive winds I didn't want to go with a vent that lifts off the surface. I got them here:
because Amazon does a decent job of carrying lots of stuff.

Of course this is motivating us to put up my old/cheap hoop greenhouse. It's made from hog panels and rail road ties. :D I think I might go to FarmTek and get some of the decent plastic greenhouse panels they sell along with the appropriate H and U channels for that. It'll be our starter and test bed.

One thing always leads to another.
