i saw about the best idea ive seen in a long time today whilst looking at infant schools for my twins i found one which had a green house made from 1500 2litre plastic bottles the bases were cut of then a bamboo cane was threaded through the bottle enableing them to be attached to a frame thus creating a 6b4 green house i will try to find a link to some thing simular
i thought great i can easily make that except ................................................................................... at approx 1 bottle of pop a month it will take (bugger ran out of toes

) a bloody long time to collect the bottles
