I tried to do a search on the geodesic dome kit, but could not find one appropriate.  I did see one where someone stretched plastic over a wood one making a greenhouse…

But this is a different idea, maybe…..  I’m sure someone has thought of it.

So you have the dome kit.  Very cool design.  What about taking some PET, and the sheet press with a mold to make windows for the dome to make it a greenhouse?

Seems like it would be a good use of the PET, if it could be made into a sheet that would fit into the triangles.  Would have to alter the dome design some to incorporate a door and a vent.  But the biggest challenge would be the window material out of old bottles.
