The MgSO4 in crystal is probably the same as MgSO4-7H2O
The H2O is water of crystallization, MgSO4 without water would be a
dry white powder.
The molecular weight of MgSO4 is 72
the molecular weight on the hydrate is 198
So 198 grams of the crystalize form would equal 72 grams of the dry
anhydrate.
Grocery stores and pharmacies also sell the stuff as Epson Salts. You
might be able to get a smaller amount there. Save some for the
roses.
