Thank you to everyone for all of your help about poly tunnels. We decided in the end to buy a 2mx3m from the garden centre as they were on offer. After looking at a few of them in use we think we can modify one i.e. anchor it down onto heavy chunks of wood and bury it a bit more than suggested. (we are not tall people so a few inches won`t make any difference) Also we are going to make proper doors at either end, use hot spot tape, also put scaffolding planks around the insides which again we will bolt to the frame, plus the frame is 25mm not 19mm like some. Its cost £90. we have enough wood laying around for the frames etc., and if the cover goes about £60 should get a new one. Can but try, seems better than £300 which would be the cost of the others. Would not mind the cost so much if it was at home but its on an allotment and we do have vandals.
