GuanoKalong Fertilizers: Bat Guano for Powerful Organic Cultivation

GuanoKalong revolutionizes organic nutrition in indoor cultivation with its bat guano-based fertilizers. For decades, this Dutch brand has been exploiting Indonesian caves to harvest exceptional guano, naturally rich in phosphorus, nitrogen, and potassium. Unlike mineral fertilizers that acidify the substrate, GuanoKalong guano maintains a stable pH while nourishing the microbial life of the soil.

Why choose GuanoKalong fertilizers for your indoor grow

The secret of GuanoKalong lies in the quality of its guano harvested from the caves of Java. This ancient guano contains up to 15% assimilable phosphorus, perfect for triggering explosive flowering. The range covers all needs: from nitrogen-rich Kalong Grow for vegetative growth to phosphorus-concentrated Kalong Bloom for flowering. The Guanokalong Florizon intelligently combines these two phases in a single product, drastically simplifying fertilization for growers who want performance without the hassle.

The advantage of guano over chemical fertilizers? Zero risk of root burn even with slight over-dosing. The microorganisms present in guano bind to the roots and create a symbiosis that improves nutrient absorption by 30% compared to conventional liquid fertilizers. The result: plants more resistant to water and heat stress, crucial in indoor cultivation under high-intensity LEDs.

How to choose your GuanoKalong fertilizer according to your setup

For the vegetative phase, opt for Kalong Grow if you are growing in soil. Its NPK ratio of 4-3-3 perfectly nourishes young plants without excess nitrogen that could delay flowering. In coco or hydroponics, prefer liquid versions that dissolve instantly without clogging irrigation systems.

Flowering requires more finesse. Kalong Bloom with its NPK 1-10-1 boosts resin production from the 3rd week of bloom. For demanding varieties like Haze or Sativa dominant, combine it with Kalong Bat Mix as a substrate amendment. This pure guano powder releases its nutrients over 8-10 weeks, perfect for long flowering periods.

Regarding dosage, count 1-2g per liter of substrate for powders, and 1-2ml per liter of watering water for liquids. In living soil, reduce by half because microbial life amplifies the effectiveness of guano.

Frequently asked questions about GuanoKalong fertilizers

Which Guanokalong product should I choose for the growth phase in indoor soil cultivation?

For growth in soil, Kalong Grow remains the reference choice with its balanced NPK 4-3-3. Its granular formulation mixes directly into the substrate during repotting, gradually releasing nitrogen over 4-6 weeks. If you prefer precise nutrient control, the liquid version Kalong Grow allows for milliliter-accurate dosing with each watering. For beginners, Florizon simplifies everything by covering both growth and flowering at once.

How to accurately dose Kalong Grow to avoid over-fertilization in a 7L pot?

In a 7L pot, mix a maximum of 14g of granular Kalong Grow into the substrate, which is 2g per liter of soil. This dose covers 4 weeks of growth without risk of burn. For liquid watering, dilute 7-14ml in 1L of water depending on the vigor of your plants. Always start with the minimum dose the first week, then gradually increase. Since guano is organic, it takes 48-72h to see the effects, unlike mineral fertilizers which act in 24h.

Is Kalong Bloom compatible with automated indoor irrigation systems?

Absolutely, but only the liquid Kalong Bloom version. The filtered formulation passes without problems through drippers and sprinklers up to 2mm in diameter. Avoid powder versions which risk clogging pipes despite filtration. Prepare your nutrient solution a maximum of 48h in advance because liquid guano can ferment and alter the pH after 3-4 days. Clean your circuits with clear water between each cycle to avoid organic deposits.

When and how to mix Guanokalong guano powder into the substrate for better assimilation?

Mix the guano powder 7-10 days before planting to allow its activation by the substrate's moisture. Incorporate 20-30g per 10L of soil, then water lightly to trigger microbial colonization. This pre-activation transforms the complex nutrients of guano into forms assimilable by the roots. If you plant immediately, reduce the dose by half because assimilation will be slower in the first few weeks. Activated guano retains its properties for 3-4 months in a substrate stored away from light.

Can Guanokalong be used alone or should it be combined with other organic fertilizers for optimal flowering?

GuanoKalong can absolutely be used alone for a complete cycle; this is even its main strength. Guano naturally contains all the necessary macro and micro-elements, plus enzymes that facilitate their absorption. However, combining Kalong Bloom with an organic flowering stimulant like molasses or seaweed extract boosts trichome production by 15-20%. For very demanding varieties, add Kalong Bat Mix as a top dress mid-flowering. This synergy of guano + natural stimulants maximizes genetic potential without unbalancing nutrition, as chemical fertilizer cocktails can do.
