Thanks, looking forward to shots of the insect damage! I've got some yucky spots showing up on some of my leaves at the moment, and wonder if they look anything like yours. Mine aren't holes, though, they're more like grayed out flakey-shaped irregular spots. I'll also get some pics. In the meantime I've sprinkled on a fresh dose of diatoms!
So the plastic isn't food safe, I guess? What I think would be really cool is hemp-based resins rather than what I assume is petroleum.
