Rockwool soaking time??

[sweetnug]

I was wondering if 8 hours of soaking rockwool in the conditioning solution will be suitable. The bottle says overnight and I think that could be 8 hours help would be appreciated.

Twenty four hours at 5 ph, then check your return, and hopefully it will read 5 8 ph ,one time I had to neutralize the rockwool for two days, hope this info helps JR
