what is the latest you can clone?

So putting seeds or clones in rockwool that was soaked a few minutes prior with 6.0 water is bad?

I soak my rockwool
at least 24 hours in ph5.4 and I don't have any problems...If you want to soak it a few minutes and use it, well that is up to you...as Zandor says, I go with what I know works!
