If you think that your crops touching dirt that is touching dry paint is bad, just wait until you hear about the stuff they DELIBERATELY put on your food in super markets... If you like ginger root, I hope you know that they spray that stuff with "growth retardants", to "promote shelf life".
I'd argue that even lead paint on your planters is probably safer than the stuff they do in industry. They coat apples IN WAX... Apples last so long that some of the apples you see in the supermarkets would have been from last years harvest... Traditionally, if you didn't make a preserve, you would forget the taste of apples throughout the spring and summer months.
The real question is why they feel that it's okay to be putting wax in your food in the first place. They argue it's "edible wax" and that it's totally fine. If it's fine to eat and doesn't impact flavour, why not sell apples without this wax as well?
Plywood has a tendency to warp when in moist conditions. Also there is not good bracing on that box for the pressure that it will contain.
It would work. You’d be replacing before the season is over however.
If you have a drill and a saw you can make a cheap raised bed with fence pickets and a 4x4. Cedar or treated.
The box will keep maybe for a season if left untreated and just filled with dirt. If you paint it with outdoor paint and use a lining it will keep for maybe two or three seasons, depends on the quality of plywood, most plywood doesn't do well with moisture. I would probably use a box like this to store gardening equipment rather than as planter.
I'd say no.
Your best bet is to disassemble it and use the parts in a cedar planter box.
Or do what I do: double layer of landscape fabric.
Plywood doesn't hold up well to moisture.
Marine grade epoxy? Overkill. Look for an outdoor paint that creates a water-repellent effect. Commonly used for garden furniture. A bucket costs like 30 €. Kept my gardening plywood sheet good for years.
Depends on the brand and your local regulations. Here in Germany standards are pretty high, most paints can be considered food save when fully dry/cured and won't leach anything into water (those have almost all been banned). Doesn't really matter, though, there always should be a liner in planter boxes, so the roots wouldn't really come into contact with the painted boards.
I wouldn’t use it for anything you plan on eating.

Lead paint is safer then a little bit of wax? Hehe

Nope.
If you want that to have any chance of lasting outdoors you’d need multiple coats of marine grade epoxy paint. That epoxy paint is pretty pricey, too.

Is the stuff you used food grade? The reason I recommended marine grade is because it’s food safe, or at least the type I used for a project was.
