1 gallon water
5 inches of a stocking

take the 5 inch stocking and tie one end
add 3 teaspoons of guano and then tie the other end
hang the stocking in the gallon of water and close the lid with stocking hanging out a little.
shake it up every few hours for 1 day until the water is dark

water your plants and the next day you will be happy. I dont like to add anything else to this mix but you can. Try just guano first and then add new things next time so you know what works.
