Metal Glazing Strips

so you want to order a Growingspaces Greenhouse, they are the best so far, two things I would do
if you decide on the metal strips instead of the high tech tape, you'll really want to notch all the struts and find a better sealing tape, I have found the one that comes with them falls apart in the sun (make sure you trim it tight to strips) causing leaks, you can caulk the upper edge, it just looks bad after a short time, I am testing metal tapes now, there must be something out there that will work really well. The Metal Glazing strips are a great concept though not a finished product and should only be used if your willing to keep a keen on on them for leaks, don't over tighten the roofing screws, the rubber gasket allows for expansion, I have heard they can fall off
due to heat and cold, if your not will to notch the struts (double hub only) then you'll have to watch your glazing screw placement to avoid cupping at hubs heres a link to a dome that had major leaks after 6 months http://picasaweb.google.com/rvolkmar/Salida182010#

Our Second Done

Still in 2002 Pam and I were contracted to build a 42' Dome Greenhouse at Mineral Hot Springs
Pam and I worked from the foundation up and then on the interior planting beds.
we started by digging down 1.5 feet and building a Quick Tube and Earth bag foundation, as you can see in the pic's this dome turned out very well http://picasaweb.google.com/rvolkmar/Joydome# to the Ginkgo tree is nearly 18 feet tall some maintenance has been done buy the hot springs staff.http://www.joyfuljourneyhotsprings.com/

Back in 2002

way back when Pamela and I were caretakers at Sanctuary house, we built our first GrowingDome for Growing Spaces, it was a 33' geodesic solar greenhouse
Nic the owners son can to supervise the construction, it was an amazing dome build and even more amazing greenhouse, we planeted it up with some help from Jerome a peraculture guy, that also brought White fly infested plants, now that was fun to deal with.

we dug our foundation in January, built in April, and were in full blown production by the first of july  http://picasaweb.google.com/rvolkmar/Sanctuaryhouse#

in this blog I'll start writing about our journey into these growdomes, some of the problems with them and how to correct them and improvements that can be made..-Rodney
