Has anyone out there got an old polytunnel frame they want to sell? Im looking for a large size min 12x20 straight sides preferred would take much larger size if reasonable.

you could use the 1/2 inch plastic piping that is used by water companies . check your builders yards .. use concrete to secure it  and erect it iusing rope to keep is spaced right

thanks for that, worth considering

i reckon you could make a pollytunnel that size for well under £100

Good idea Muntjac that stuff's only about £20 for 50m.
Might try that myself any ideas for a source of cheap plastic for poly tunnels ?

a roll of dpm membrane ask for the widest  size they stock ....

i think 25mm water pipe would be a bit flimsy and would be hard work.i was thinking of 32mm or even 40mm waste pipe they come in 3m lengths at £3ish each fit 2 together with a coupling 50p each this would form the arch shape. you would need a few more lenghs to go the full length at the peak and on each side at waste high,when these long straight lengths over lap the arch you could fasten the 2 together with a large jubilee clip.
a timber end each end,£40-£50 quid would get that i'm sure with scrap timber.
all you need now is the poly

handy these building folk,another one to look out for is harris fencing or block n mesh you know the stuff that we fence jobs of with,half a dozen of these and you have a brilliant brassica cage,butterfly nets are optional.
