I did the same thing, ran out and bought a couple bags. Have not run it yet, but I droppped some Blue Dream cuttings into it, watered one time with some tap water at about pH 6.0, stuck them under a slightly vented dome, and ignored them for ten days or so.
5 out of 6 of them rooted, the one that did not was a janky cut anyway. So it works dandy for cloning. Being a hobbyist is very liberating sometimes, I basically make clones a different way every time, because the cost of failure is a non-issue. I really want to buy a little EZ Clone machine soon, though.
I think I will run Shoreline's beans in the Tupur, when I finally get to them.
