Apparently there can be some salt in it, depending on the source, but the hydroponic guys assured me that theirs doesn't have any, and a good rinsing should take care of it if it did, so I don't really see that as a deal-breaker.
So far I've had good results re-potting VFTs from smaller pots into it, but I think I've always left the peat moss soil from the smaller pots intact around the roots when I did it. That's about the extent of my experience with it. I'm trying some other things, but it's too soon to tell how well they're going to work, so I'll hold off on the details.
I'd love to hear other people's experiences with it.
It's just my email address and an expression of the oxymoron that I often am.
Call me Tim, if you prefer.
