Steps in Detail

Important: If the water is too hot, the oxygen levels will be lessened, and if the water is too cold beneficial micro-organism growth will be slowed. The water should be from approximately 60 to 90 degrees.

1. Get The Water– Get a gallon of “pure” or non-chlorinated tap water. It is essential that you only use pure, non-Chlorinated water. The reason that non-chlorinated water is criticals that bat guano’s soil enriching microbes are killed by chlorine. Normal tap-water will likely have chlorine. So, suppose you are using tap water. In that case, you need to place the water in an open container either for around 24 hours, which will allow the chlorine to naturally be released.

Bat Guano is an organic plant food that contains three of the most essential nutrients needed for cannabis and other plants: Nitrogen, phosphorous, and potassium. Nitrogen is beneficial for making your cannabis plants nice and green by photosynthesizing and making sugar that plants need to acquire thick, bushy, green leaves.

Some of the expected benefits of potassium are disease resistance and helping plant process water efficiently.
