new project "our first greenhouse"

do you leave the two halves attached then?

 

yep, it helps with stability.. you just sort of fold it in half upwards

 

re- the decking, ive put a water proof membrane on top of the decking, so i dont think it will get mouldy, but then i put some black weed control barrier on top of that, as i thought the roots might like it(and it looks better than blue plastic) this might be a problem!

Ive also had some black polythene tubing given(about 4" or 5"), im not sure what its called, but im certain that its for growing things in, any ideas?

 

Sounds alright, i`d cover it with white poly or paint it white as the black will get very hot and cook the roots inside.
I had moss growing on the underside of the weed barrier i used for my tomato hammock, its finally given up the ghost and started to tear along the back edge where its clamped to the framework. It hasnt done bad considering its been sat outside for 3 years full of wet compost :wink:
