Shreiner's recommends a specific formula they recommend for potting. It is pumice, fir bark, & peat moss... I don't know the percentages off the top of my head but I think it was about 40% pumice 35% bark 25% peat.. I was thinking of experimenting with some historics that I would probably just toss or put somewhere they wouldn't be seen anyways so if I lose thrm, no biggy. I'd have to order the pumice, I've never seen it for sale before. The fur bark I can get in small quanities as orchid mix but it would be nice to find a bigger bag.
