cheapest green house

Don't be afraid to ask someone with an obviously unused G.H. in the garden if they want to get rid of it! You could be doing them a favour! You may have to take it down and put it up again. Then you'll know all about greenhouse construction by the time it's done. 

thats how i got my free 1, my next door neighbour had a 6 x 8 in the garden and her son was smashing the glass when  he was in a bad mood, which made me mad seeing a good greenhouse going to waste,
so after we payed 100.0 for a 2nd hand 1 for our garden, moved plots and thought it was safe to get a greenhouse my o/h plucked up the guts to knock on her door and asked what was they going to do with the greenhouse and she said she was going to rip it down and dump it at the tip, so he asked if we could have it and she said yes ......
