I need boost my Ca without added N. What is a good alternative to calnit???
I think this will end up settling to the bottom, no?
Pure calcium sulfate dihydrate is indeed fully water soluble
Yeah, I've tried both adding it to water and top dressing it + watering it in and in both cases it dissolves immediately.
Thanks everybody

Not all gypsum is the same, this is from the item i linked:.
Maximum solubility 2 grams per liter or 7.7 grams per gallon.
Really?
I don't know about "all gypsum", and I did not even mentioned "gypsium", but solubility of Calcium Sulfate Dihydrate in water is ~0.2% at room temperature. That's a fact.
What were you hoping to accomplish in post#11 when you said^ quoting me saying its "water soluble" not "completely soluble"?
!
Better yet use something like Ca EDTA or Ca Acetate or even Ca Cl (as long as a bit of Cl is acceptable) rather than chance it with gypsum. Fact is no hydro nutrient manufacturer would go anywhere near gypsum and gypsum while being fine in soils (and widely used)isn't the best option for hydro. Lot of attitude getting around but how does that help the person who asked the original question. It's not a competition.
