Batt Guano Tea what week to add what week to stop

What week of flowering is best to add bat guano tea and what week to stop??

Found this information that may give you some guidance. There are several types of Guano.

Bat guano comes in different types. The N-P-K ratio of the guano is dependent on what the type of bat it came from and what it’s diet consists of. For instance, Mexican bats eat bugs so their guano is high in nitrogen. While Jamaican bats feed on fruit, so their guano is high in phosphorus. Lets explore some different types of guano and their application.

Mexican Bat Guano (10-2-1). This type of guano is very high nitrogen. This makes it perfect for the vegetative stages of growth. Even when the plant is young it can be fed a dilute mixture if the soil happens to contain very little nutrients. This type of guano can be used throughout the vegetative stage of growth.

Peruvian Seabird Guano (10-10-2) This type of guano is NOT bat guano. It comes from Peruvian seabirds and is very “hot”, meaning it will burn plants very easily if prepared incorrectly or over applied. Not good for flowering due to high nitrogen content.

Jamaican Bat Guano (1-10-0.2) This type of bat guano is high in phosphorus. It is perfect for the early-mid flowering cycle once females are well established.

Indonesian Bat Guano (0.5-12-0.2) This type of guano is the ultimate low-nitrogen, high-phosphorus bat guano. It is perfectly suited for the end of the flowering cycle before the final flush. This drops nitrogen levels low to cut growth and signal the autumn harvest as well as provide a huge resource of phosphorus to bulk up buds and add to trichome count.

As you can see, ideally you use Jamaican for early to mid flowering and Indonesian for late flowering. This is the best answer I can come up with. Hope it helps. Good luck on your grow. Jerry


Thank you so much this gives me a good starting point :point_up:.
