i think you are going to need to call a museum curator or someone like that cause i'm totally unqualified to answer that question.
but i can handle your question about the turface/rh mix.
i like the holes still with this mix but i am putting a 4" wide strip of regular fiberglass window screen against the holes on the inside. i'm also putting a small piece down the tailpiece from the inside.
No D9 for 4 days, hope all is well. Screen it is. the 3:1-8822(turface substitute):rice hulls will be heavy, like you mention in you first posts in this thread. but not as heavy as your 100% turface examples. I recieved the rice hulls last week, the look like little roaches (the bugs). The 8822, I'll have to go raid napa soon. I'll be happy not to have gnats in the future. Hows the G13 doing?
