well i have been doing a lot of research on this subject matter and i wanna see what other people think. I read that putting egg shells in water(evaporated) or distilled with a clean egg shell and the water from this is suppose to help balance the pH level. But I was making a soil mixture today I am on a tight budget so I try to do research on what everyday items will help plants, soil etc so its mostly miracle grow, vermiculite, plant nutes., and this combo. I kind of come about just reading different sources, I made sure everything was throughly clean and got egg shells, put them in my blender, blended with water, retained the water to use for my plants, and got the ground up egg shells and put them with my soil matter, i mean its a perfect example of not wasting any materials. Feedback anyone?
