- CERTIFIED COCO COIR: Made from 100% RHP-certified, peat-free coco coir for a clean and efficient growing medium that’s free from additives and nutrients. Our high-grade coir is designed for a clone or seed to veg and flower in—1 gallon cube.
- RAPID ROOT DEVELOPMENT: High pith ratio coco coir ensures fast seed germination and strong root growth. Superior water retention keeps roots hydrated, while enhanced aeration prevents compaction and promotes oxygen flow, for a healthy plant environment.
- BUFFERED AND pH STABLE: Our coco coir undergoes meticulous buffering with calcium and magnesium, stabilizing its pH and enhancing its nutrient uptake, while the coir’s natural structure promotes robust root development for healthier, stronger plants.
- TRIPLE WASHED & LOW EC: Triple washed to remove excess salts and ensure a low EC level, our coco coir is a clean, pathogen-free growing medium. Washed, rinsed, buffered and dried to remove any nutritional imbalances, providing a safe, stable environment.
- HIGH CATION EXCHANGE CAPACITY: Our coco coir cube features a naturally high CEC that allows it to retain and release nutrients efficiently. Because of the aerated fabric bag the growth rate and dry down is enhanced greatly.
- MESS & HASSLE-FREE: Designed for efficiency, our Coco Cube features a breathable fabric wrap that enhances airflow to roots and keeps the growing process clean with less mess. It also includes pre-drilled holes for seamless drip-stake compatibility.
- SUSTAINABLE & ECO-FRIENDLY: Made from renewable coconut coir and sourced from a single farm to ensure consistency and quality, Coco Cube supports sustainable growing practices while providing an eco-friendly solution for seed starting and propagation.
