Now that I have a clean shiny greenhouse back in position I am thinking of connecting the gutters along each side to catch the water. But.....
can I find anywhere that sells 35mm diameter half round piping/guttering/joints etc ?

heck no

searched the interweb, googled, tried local stores

nothing. Any suggestions ? I am fairly good at improvising and adapting [ok, bodging] but this has me stumped.
It is an older aluminium greenhouse, the gutters are part of the structure. I really want one end stopper, a way to connect the two sides across the back and a down spout/stopper at the other end. Is it too much to ask ?
