DIY Barr's GH Booster?
Between my dry ferts and home brewing I have the ingredients to make GH booster. I have seen it listed as a 1-3-3 ratio.
Magnesium Sulfate (Epsom Salts).
Potassium Sulfate (K2SO4)
Calcium Sulfate (Gypsum)
Mix in 1:3:3 ratio.
My question is, is that 1-3-3 by weight or by volume? 1tsp gypsum is lighter than 1tsp ofK2SO4 or MgSO4?
While I'm at it, Why does PPS Pro dosing include MgSO4, and EI does not?
