Used by growers looking to increase flower weight, essential oil production and overall flowering quality, Rox delivers a simple, effective solution for stronger, more productive harvests.

Rox is formulated to supply additional phosphorus, potassium and bloom-enhancing compounds during the flowering phase. These key elements support heavier flower formation, enhanced essential oil production and more robust plant development. By supplementing your existing bloom nutrient program, Rox helps your plants reach their full flowering potential without the use of synthetic growth regulators.

Perfect for growers seeking maximum yields, Rox works seamlessly with standard nutrient schedules in soil, coco coir and hydroponic setups.
