how long i cant find for rw

how long does it take for germinated seeds to sprout from rw. used a paper towel,when seeds cracked moved to rw.

I totally don't get what you're asking, nor the poll. Ok, girl, let's start from the beginning.

rw=... rockwool? Gotta be, gotta be! That helps.. so, all I know is that it's difficult to keep pH where you want it with some rockwool (many other factors seem to go into this, but hey). I don't think it should be much different from soil, and in my experience it takes anywhere from a couple of days since planting a germinated seed, to two full weeks before it pops its little head out into the light.

Does that help answer your question?

yeah,that was exactly it. ty,reps to yu
