Bat guano fertilizer

Guano is ideal as an organic soil amendment, either dug-in around the plant or watered-in as a tea. It makes an ideal backbone to any soil recipe, and has the unique characteristic of never burning plants, unlike most nutrients. Fruits and vegetables grown with guano are more flavoursome and resistant to disease. It is the same with cannabis. Guano will “mango” or sweeten the bouquet and flavour of buds when dry.

  1. Dig it in (under the mulch) so that it activates properly
  2. It will dry, clump, and not work as effectively if only sprinkled on the surface
  3. Water-in well

The diet of the particular bat species can alter the nutrient profile of the guano. Insect-eating bats produce a guano that has a high nitrogen content. This makes it ideal for fertilising during the vegetative phase. Fruit-eating bats produce a guano that has a high phosphorus content. This is best for use during the flowering phase when cannabis has a higher demand for phosphorus.

The savvy contemporary cannabis consumer is learning to demand high-quality, organic marijuana. Guano is one way of achieving world-class quality when growing organically indoors or outdoors.

  1. Use 1 tablespoon of guano per litre of water
  2. Use warm water, not hot! You will kill the microorganisms
  3. Stir the water as you add the guano
  4. Leave to rest overnight
  5. Use once per week to guarantee lush growth

The benefits of guano for plant growth are numerous:

  • It improves soil texture. If the soil is too loose, guano will bind it better and increase water retention. If the soil is too dense, guano will loosen the texture and let water penetrate more efficiently.
  • Bioremediation. Guano can help flush toxic elements from the soil while protecting the roots microbially and continuing to feed the affected plant.
  • It encourages healthy decomposition of exhausted material. Adding guano to compost speeds up the composting process and improves friability.
  • It is a slow-release fertiliser. Guano will provide nutrients for most of the life of your plant.
  • It is a pH-adjuster, buffering the pH of the root system.
  • It controls nematodes and is a natural fungicide against chitin (from insect shells).
  • It keeps soil friable and acts as a soil conditioner. Guano adds beneficial enzymes and microflora for continuous soil health.
  • When combined with other additives like worm castings and various meals, guano helps create thriving colonies of root fauna.
  • Used as a dilute spray, guano can help provide plants with fungal protection.

Two million tonnes were imported by Britain from 1840 onwards, and the government of the United States made it a matter of agricultural necessity. During his tenure, President Fillmore said “Guano has become so desirable an article to agricultural interests in the US that it is the duty of the Government to employ all means properly in its power for the purpose of causing this article to be imported into the country at a reasonable price”.

Use guano as part of an organic soil mix from the start. Along with bone meal, chicken manure, feather meal, and rock dust, guano provides a broad spectrum of essential nutrients, vitamins, and minerals for the cannabis plant. Try this recipe for bountiful cannabis growth.

Guano has been a respected organic fertiliser for centuries. When used to grow cannabis, it often produces spectacular results.
