Home made Cal-Mag vs bought

Hey everyone! Ok I’m asking everyone their opinion on this subject. Home made Cal-Mag verse store bought, is there a major difference. Does it matter which you use?

I think most people don’t know how to make their own calmag. How did you make yours?

With ground up egg shells and vinegar…for the Cal. Heat egg shells until dark brown. Grind fine if you can. Add vinegar to eggshells. Let the react until vinegar smell is gone. I start with a 4/1 ratio. 4 vinegar to eggshell. Mag…I use teaspoon of epson salt. I’d appreciate any input from other farmers too!

You’re good.
