Coco

Hesi Coco is a base fertilizer developed by Hesi specifically for cultivation in coconut coir substrate. It can be used throughout the entire grow cycle — both vegetative and flowering phases — though Hesi recommends pairing it with their TNT Complex during veg for best results, then using Hesi Coco as the primary base during flowering.

Like the rest of the Hesi mineral line, Hesi Coco includes not just primary NPK but also a complete micronutrient profile, B vitamins, amino acids, and vegetable sugars that support enzyme activity and metabolic efficiency in the coco root zone. The formulation accounts for coco's unique cation exchange behavior, which requires elevated calcium and a carefully balanced ionic profile.

Use Hesi Coco as the foundation of a coco feeding program, pairing it with Hesi Boost, PK 13-14, and SuperVit for a complete grow. Compatible with hand watering and automated fertigation systems. Made by Hesi, a Dutch nutrient brand whose complete feeding programs have been widely used in European cannabis cultivation for decades.
