I also like the Elite greenhouses, but I've only
seen photos of them online.





I'd want to know how the panels of polycarbonate are sealed so insects
and water don't get down into the channels.
Great idea would be to have a propagating end to a greenhouse that has
polycarbonate whilst the rest has safety glass!
