What exactly is Tom Barr's GH booster?

Do I really need it? Also do I need calcium chloride or calcium sulfate? Thanks

The GH booster is used to boost GH; this may or may not be required depending on your water parameters.

The composition of the GH booster is: 2 (K2SO4) : 2 (CaSO4) : 1 (MgSO4)

You can use calcium sulfate, but it isn't very soluble.

A combination of CaSO4 and CaCl would probably be best unless you're using r/o water.
