I have an old aluminium framed greenhouse and have thought about collecting rain water from it (after I replace a missing pane), what would be the best way to set this up (without too much expense)?
Well that is where you start
75mm size works well. This sort of stuff

Whats the black length of hose hanging off of the far left corner?
Also , appreciate the Greenhouse is old but do you see any brand or marks on it to indicate what make it is? My missus works in this sector and may be able to match something up.
Ok, I think I know the bits I need and the general setup but I am not 100% sure how it would attach to the greenhouse.
It is pretty similar style to this and quite old with no obvious way to attach anything to it.
Normally they attach with brackets at the join of the wall and pitched roof - but it varies by make. Can you get a macro photo of how yours joins the wall to the roof?
