Thanks for your interest. The video I followed is on YouTube (Quickcrop) this gives good information. I mostly re used timber so that part of the cost was negible. The initial costs involved were for - pool liner membrane, course builders sand, a sizeable length of soil heating cable with a thermostat. (Parasene are very reliable). You must build a very strong support system though as the amount of wet sand required is very heavy. Sorry I have not provided any photos as they wouldn't help you, currently the bench is fully covered with seedling trays etc. Hope this helps and happy growing.
