The box I cobbled together from old pallets, dirt is a mix of potting soil and local dirt spiced with chicken poo.
For the more observant viewers, you may notice that the closest 'V' is slimmer than the upper square -- the pallets were a little short. I plan to plant smaller vegetables in those areas.
CCA is banned for ground contact construction. Pallets don't have that restriction, nor do you know that the pallet was made in the US where the law applies.
But CCA is the least of things to worry about. As I already said, pallets can be subject to spills of very dangerous chemicals.
WTF is wrong with you? Read my first post again. I didn't say pallets are made from old CCA, I said they are subjected to all sorts of dangerous chemicals over their life.
Then you failed to read the follow up post where I didn't say CCA isn't dangerous. I reiterated my claim in my original post that it makes it more dangerous than cca.
Do you understand the difference between a mild poison and a dangerous poison? Your earlier post makes it clear you don't understand that eating cockroachs is less dangerous than drinking benzene.
