There is a lovely old feller who makes portable frames from that very
material. He made mine by cutting two wooden side ends exactly the same,
sloping from back to front. The wooden back end was much higher than the
front. Two struts were added across the top for support and stability. The
polycarb sheet consisted of four planks and these could be removed when
plants decided to shoot up high in any area you choose.. Because they were
translucent, the seedlings were warm and protected from the sun and cuttings
could not fail to root. When it rained, the poly took the shock and
diffused the water directly to the plants. I never remove the planks to
water, just aim the spray over the whole frame. It is the best frame I have
ever used. The old guy collected the scrap plastic from a local plastics
Co.

I've built a complete greenhouse out of it and its sturdy stuff (the
thicker
stuff used for conservatory rooves)....you can't really glue it together
as
it's hollow, but you can use 1X1 timber at the corners and use small
screws
to hold it in place, if it's the really thin stuff, you can score it with
a
knife but not cut it right through, and bend it at ninety degrees, using a
staple gun to affix it to the corner struts.
