The materials are 10 litres water from washing rice and 1 kg dry eggshells.

I mixed these material and leaved it for 7 to 10 days. I can do the dilution in ratio between 1 ml hormone calcium per 1000 ml water before using with our plants. Especially, I use it in flowering stage of plants(fruit). I am also use it with vegetables.
