Does anyone know what material the Fatman used in the bottom of his tubes?

Silk screen. I wish I knew what mesh, as I'm going to need some too. When I search for silk screen I see anything from 80-235 mesh. 80 mesh would be ~177 micron according to various charts. I think the screen would get plugged in mist pretty fast and turn into an NFT with a ~100 micron droplet size, but I could be wrong.

I'm planning on hitting the local fabric store and see if I can find something in a 20-30 mesh, which would be ~850-600 micron. I don't know if the roots will grow through it or not.

Hopefully somebody who uses it already will chime in :)

Here's where tree farmer mentions using silk screen: https://www.rollitup.org/hydroponics-aeroponics/254876-my-true-hp-aero-plug-4.html#post3255758
