Anyhow, my test stuff came out that every single RR, even if it got sorta dry, rooted in at least 1/2 the time of the rockwool. As I tore apart the rockwool, I was noting only the beginnings of rooting, yet at the same time I had 5-10 roots coming out of the RR. Since keeping them moist better I think they take in 1/3 the time of the rockwool and take much more vigorously.

For what that is worth. I am sold on them for sure. Use the holding tray stuff tho, it really helps.
I've thought about trying them. I pre-soak my rockwool plugs before I use them with a mild nutrient solution. RR has nutes for starting/rooting clones. I'm getting ready to clone a couple more small lower branches and use a dome on them to see if they will root quicker. I have just enough rootech to do two more. RW is cheaper too!!!
