I am about to build a greenhouse on our new allotment, the size of the
greenhouse will be 12ft by 8ft, I have been to BanfQ, and walked around
the
other allotments to get some idea's, what caught my eye was a greenhouse
built using Perspex sheets, it looks really good and seems to be
maintenance
free, i.e., no broken glass to replace, also, no wood to rebate for the
glass and no putty or silicone to secure the glass, just screw or nail the
sheets to the frame

Can anyone tell me the advantages and disadvantages of a greenhouse made
from corrugated Perspex, any suggestions welcomed.

Cheers

Jim

One big advantage is that it won't be susceptible to damage to the same
degree as a glass one. I believe the main disadvantage is that plastic does
not admit light to the same degree as glass. This will be of most relevance
in spring when light is at a premium, or if you are at northern latitudes
this will be a consideration. Also plastic will get scratched etc and
gradually become opaque, cutting light down even more.
