Black Pellets

Guanokalong Black Pellets are an organic super fertilizer made from a mixture of Guanokalong bat guano powder and humic acids, pressed into a slow-release pellet format. With an NPK of approximately 1-10-1, they're heavily phosphorus-dominant — making them ideal as a flowering amendment for cannabis and other fruiting plants.

The pellet format allows the fertilizer to be mixed into soil or substrate before planting, where it releases nutrients gradually over weeks as moisture and soil microbes break down the pellets. The humic acid component enhances nutrient uptake efficiency and improves soil structure, while the bat guano provides natural organic phosphorus that enhances flavor, quality, and yield compared to synthetic phosphate sources.

Mix into substrate at planting: approximately 100g per 10L of growing medium for containers, or 300-500g per plant when planting in the ground. The slow release nature prevents over-feeding while ensuring steady availability throughout the bloom phase. Compatible with Guanokalong's liquid products for a complete organic program. Made by Guanokalong, a Dutch brand.
