It’s PLA. I honestly hadn’t considered the microplastics when using this material as a growing container. Though I do know not to use it to make cups and bowls and stuff that you eat out of.
I think my printer can print ABS, although I’ve never tried. Would that material be safer to grow in?
Thank you for the knowledge! It looks like foodgrade petg is 3 times the price and I don’t plan on changing nozzles and stuff to keep everything kosher anyway. So I reckon I’ll use regular petg and hit it with Shellac for the redux. Unless you have a food safe resin seal to recommend based off your research?
Hobby woodworker here. Shellac is great for an initial seal, but isn’t waterproof. I suggest using a two part epoxy instead. You don’t need a very thick coat, so you could even use a crack filler and/or self leveling variety.

Certified food-grade PETG + food safe resin seal is the best from what I have read (I researched a bunch as I am building a greenhouse)
