GK-Organics - Guanokalong Powder
Powerful Bat Guano Additive
Guanokalong Powder is one of the most popular guano additives on the market. Bat guano consists of accumilated bat droppings that have solidified in caves over many years. Guano is extremely rich in macro and micronutrients that promote rapid growth and development. Over time, microorganisms in the soil break the guano down, making the nutrients available to your plants.
All you need to do is mix a small quantity in with your substrate when you're potting up and let the microorganisms do the rest.
