Plant Supplements and Additives

Additives aren’t just extras. They’re powerful growth enhancers that unlock your plant's full potential. Our collection features plant supplements like L‑amino acid boosters, root enhancers, bloom stimulators, enzymes, and microbial inoculants proven to enhance nutrient uptake, support root resilience, and increase flower density.

Use them alongside your base nutrients to push genetics, reduce stress, and simplify feeding routines.
