Superglue is used in all kinds of stuff that we come into contact with every day. Dentists and orthodontists even use it inside our mouths.
Comment on Waterproofing PETG prints?

I personally would not consider superglue harmful enough to worry about plants seeping enough of it to affect the health of me eating the plant, and it’s not food grade. I’ve used it to fix cracked humidifier reservoirs in a greenhouse for example. That being said, most epoxy resin dries food grade. I don’t think you’d have to search hard for a very well performing Resin with food grade search term swapped with dining surface or some frequent use that requires food grade.

I would have assumed that dentists do not use the same consumer-grade stuff you buy in your local shop. Do you know for sure that they do?

I don
t know if its the exact same as consumer grade glue, but it`s definitely CA glue.

I would want to avoid something that leeches off into the water. That said, I am going to dilute it quite a lot since the stuff will be very concentrated. Super glue could be a little expensive for this though? I think coating the whole bed would take multiple small containers.
I know very little about epoxy resin, but that is what I often see - but is it really basically the same stuff that is used to repair boats as people use for decorations? The safety data sheets for the components are always pretty rough, but they of course say nothing about the cured state.

You seem to be worried about water eroding away resin or something to that effect. The bonds are strong enough that’s basically not a concern. It’s kinda like being worried about a Teflon storage medium because it’s got a bad safety sheet.
My recommendation is find something that’s waterproof on curing that can handle both ends of the pH spectrum and call it a day. You aren’t worried about abrasives.
Edit: UV too, depending on where it will be could be a concern, but petg isn’t UV ready either.
