Hi all I am making a box (5' x 20" x 9½")for tomato plants, it will be filled with gravel with the tom. pots sitting on top. I will be putting water into the stones to allow the tom. roots to reach down and so water themselves. This box will be made of OSB (Sterling board)and will have some form of liner between it and the wet stones was thinking of using a pond liner to line the box but one of the right size will be in the £18~19 range can I just use tarpaulin, in the £5 region for the size required) to line this box? Or should I just bite the bullet and pay for a pond liner?
