So, I tested some mudlugs in my garage, and they turned green and brittle, so I know that's not a solution. I made this setup out of some polystyrene insulation ($10) and a roll of 3M cold weather metal tape I had lying around. The box is 3' x 3' x 2'. I got 4 strands of about 55-60 leaves. I had a few left over, so I picked a variety of sizes and levels of yellow to see how that goes. I still have some upper leaves that are growing (but we are supposed to get our first mild frost tonight) and I guess I will hang those by their stalk outside and see how they do. I used an old crockpot on low with a cloth napkin for a wick. Has anyone had an issue running the crockpot long term? I'm going to check humidity in a few hours. When I started it was about 38-40% humidity here in Nashville. It's not pretty, it's not square, and it will only last one season, I suspect, but if it works, then, I'm ok with that.
