Pressure treated timber still OK after 7 years. Might contain some nasty stuff, but you don't have to lick it if you don't want to.
Convince me that "poisons" leach from the wood and are absorbed by the veg and I might have a rethink. I mean proper science, not supposition.
I like the idea of pallets but it's quite difficult to pick them up around here - for one thing, there dioesn't seem to be much building work going on, and in any case I don't have a car so I can't just act on the spur of the moment! I can hire a car for a couple of hours to pick up stuff from a supplier, but I'm not sure where's cheapest. Or is there somewhere online, perhaps, that might deliver to me without costing a future?
It's not my job to convince you of anything. The research is out there, go find it for yourself.
