I hated trimming around it, lol. Trellis wouldn't be nearly as big of a bitch as meticulously tying up each branch and finding a place to properly support it from. The green tape would work, but I don't see it as being too much easier than twine.
Lol, TWS is right, they would be mountain caterpillars if anything. But not mine, I don't have any worms indoors at all, and haven't previously. Probably just a moth flying through your room trying to find the single tastiest clone in the room to lay eggs on, I can't help it if that Critical Yumboldt is by far the most delicious, lol. But when we fimmed it in your room, we had like 4 of us inspecting it and playing with it, there would be no way we missed seeing a giant batch of moth caviar.
Spray with Bacillus Thuringiensis, or BT, available anywhere with a garden section. I haven't seen more than a few chewed leafs so far this season on the outdoor, they can barely chew half a leaf before they get sick. I soak them with it every 2 weeks, and use Spinosad in between that.
