Do ya'll have a recommended source for Calcium Nitrate? How about this one https://www.laballey.com/products/calcium-nitrate-crystal-lab?variant=7218967838779
I don’t, which is why I recommend food grade sodium nitrate that is readily available.
the linked one doesn’t give any useful purity info thst I could see. Lad grade can mean anything they want it to mean.
