How to Use Bat Guano for Flowering

Proper use of bat guano during the flowering stage of cannabis cultivation is crucial for the best results. Below are step-by-step instructions and tips for applying this organic fertilizer effectively:

Step 1: Preparation of Bat Guano

Before applying, make sure the bat guano is dry and finely ground. If it is in large granules or wet, you can crush it to facilitate its use and absorption by plants.

Step 2: Determining the Correct Dosage

The dosage of bat guano depends on several factors, including the size of your plants and the condition of the soil. A general rule of thumb is to use about 1 to 2 tablespoons (15-30 ml) of guano per plant. However, it is vital to start with a lower dose and adjust based on the plant's response.

Step 3: Application of Guano

• Apply the guano directly to the soil, spreading it around the base of each plant. Avoid direct contact of the guano with the stems or leaves, as this could burn the plant.
• Work the guano gently into the top few inches of soil. This helps nutrients get incorporated into the soil and be more accessible to plant roots.

Step 4: Watering

• After applying the guano, water your plants as usual. The water will help leach the nutrients from the guano into the soil, making them more accessible to plant roots.
• Application Frequency : Bat guano should be applied at the beginning of the flowering stage and can be reapplied every 2-4 weeks, depending on the needs of your plants. Carefully observe your plants' response to adjust the frequency and quantity.

Additional Tips

• Always wear gloves and a mask when handling bat guano, as it may contain microorganisms that are unhealthy to inhale or come into direct contact with the skin.
• Consider making bat guano tea. This is done by soaking the guano in water for 24-48 hours and then using the water to water the plants. It is an effective way to apply nutrients more evenly.
• Monitor soil pH regularly. Bat guano can slightly alter the acidity of the soil, so it is important to maintain a proper balance for optimal cannabis growth.

Advantages of Bat Guano for Cannabis Flowering
