GrowHard Nutriboost Concentrate

NutriBoost is a plant-based vigour tonic that contains kelp extracts, vitamin B, and NAA.

It has been created to boost plant vigour at every stage of development and can be applied to accelerate and improve plant propagation while lowering heat-related stress and transplant shock.

Moreover, NutriBoost enhances the development of lateral branches.

Since NutriBoost is pure and has very little residual effect, it's a better all-around supplement and a better substitute for Superthrive, especially in hydroponic systems.
