All ingredients are certified organic and the eggshells are organic and cage-free. THIS IS NOT AN EGGSHELL TEA. This is real calcium extracted from eggshells. The solution is pH balanced. The solution does exactly what eggshells do in your garden except the calcium in those eggshells takes years and sometimes even decades to be released and available to your plant’s root system. I’ve already extracted that calcium in this concentrate and once you mix a tablespoon of the solution with a gallon of water, you can spray it around your plants and your plants will have that calcium in days instead of decades! I use brand new ball jars and once you have used the solution, you can wash them and use the jars again since all the ingredients are basically edible. EACH JAR WILL MAKE 20 GALLONS OF FINISHED SOLUTION! This is your chance to support a startup small business! Thanks for looking!
