Bat Guano is the excrement of well… Bats! Guano has been harvested from the walls and floors of caves inhabited by generation after generation of native bat species, just hanging there, shitting in the dark. Bat Guano is known to have been used as a nutrient-rich fertiliser dating back hundreds of years.

Organic, natural and rich in Nitrogen, Phosphorus and Potassium, bat guano ensures vigorous growth during both the vegetative and flowering stage.

In addition to the three main nutrients (N-P-K), guano is packed full of micro-nutrients for overall healthy plant, root and fruit development, bat guano can be applied as either a soil amendment or via a compost tea feeding.

Bat Guano tea recipe during flowering

It’s extremelly easy to create your own bat guano tea to feed your plants during flowering, It’s also as important to start with chlorine-free water.

If you’re taking your water straight from the tap, chances are it will contain chlorine, that’s not a problem – all you need to do is let the water sit uncovered for 24 – 36 hours at room temperature for the chlorine to evaporate.

You will need:

Step 1) Fill a container with 5 gallons of chlorine-free water, leave enough space to stir the water without making a mess!

Step 2) Add the Bat Guano, you can add the guano directly into the water and stir until most of it is dissolved or you can wrap the guano inside a cheesecloth and let it steep for a couple of hours, like a huge tea bag.

Step 3) Add the un-sulphured molasses, this can go in the water directly as it’s mainly composed of sugars which will dissolve.

Step 4) If you’re using other nutrients, add them now, I haven’t gone into detail as people use different nutrients, but this should include stuff such as earthworm castings and seaweed, this recipe will work great on its own but is intended as a supplement.

Step 5) Aerate the tea by adding a hydroponics bubbler and let it run for 24 – 36 hours.

  • Checking the solution a couple of times a day to make sure that the bubbler is still doing its job.
  • High levels of oxygen from the bubbler will drastically increase the beneficial bacteria that will help feed your plants
  • If you start to notice a foul smell from your tea it’s likely the solution has gone bad.

Step 6) If you have chosen to add the guano directly, you may want to filter the tea before feeding it to your plants to remove any large particles, this can be avoided by using a cheesecloth like a tea-bag.

Important things to note:

Different brands of bat guano will have varying N-P-K levels, It’s widely believed that the bats’ diet plays a huge factor in the nutritional value of the guano.

For example, species that feed on insects generally produce higher Nitrogen guano whereas bats that feed on fruit generally produce higher phosphorous guano.

Hydrofarm has an NPK value of 0-5-0 and is recommended for use during flowering due to the high levels of Potassium in comparison to the Nitrogen levels.
