These nutrients support vigorous flower formation, heavier flower weight and increased essential oil production, resulting in richer, more aromatic harvests.

Compatible with soil, coco coir and hydroponic setups, Rock Resinator complements your existing bloom nutrient program to intensify flower density and aroma without disrupting overall plant health or nutrient balance.
