hi bloomer in response to your question where do i plan to get my poly tunnel from. i found an address on the grapevine posted by another user. the address is as follows...........
polytunnel
i intend to use this as a basic starting point,then adapt it to suit my needs. should be able to source bits from various areas depends on how you feel

i will try anywhere from skips to building sites, not too fussy me as you may guess, but its all about saving money. failing that i will come up with my own design.
anyone with any ideas or tips would be gratfully recieved.
