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.

And people use reclaimed wood all the time, unless you source it yourself, you have no idea unless the rating is still legible.
Also, some people avoid pesticides, so they would also want to avoid it in their frames too.
Copper is an essential plant macronutrient, so that’s just plain bullshit.
No more than they normally do. They’ve done studies on this. There’s no extra copper in the plants due to the presence of this pressure treatment on the wood using copper azole
I never said there was…
There’s also additional chemicals to just the copper dude….
Copper is a macronutrient, you want in your soil. So I don’t know what point you’re trying to make here?
The point is that modern pressure treated wood is treated with copper, so unless you think copper is going to be bad for the soil/plants, modern pressure treated wood is safe to use for garden beds.
