Salinity for curing dry rock

[thetonyage]

I've been wondering, just how spot-on do I need to be with my salt mix for curing rock? Does a small variance from 1.026 affect much during this process? If not, how big of a variance would there have to be for there to be adverse affects?

Could I use a lower salinity to save some money on salt during the weeks it will take my rock to cure?

I would probably run it between 1.010 and 1.020. Fluctuations won't matter.
