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#
