Shop hydroponic plant boosters, additives and supplements for stronger growth, healthier plants, improved flowering and bigger yields.
Base nutrients supply the core building blocks for plant growth, but no single formula covers every requirement across a full crop cycle. Plant boosters and additives fill those gaps, supporting stronger root systems, healthier foliage, bigger blooms and better resistance to pest and environmental stress.
At A-Grade Hydroponics, our booster range is built to support every stage of growth — from propagation through to flowering — across coco coir, soil, DWC, NFT and other hydroponic systems.
What's in this Collection?
Root stimulant hydroponics additives for stronger propagation and early growth
PK booster for flowering, encouraging denser bud and fruit set
CalMag supplement for coco coir and other media prone to calcium and magnesium lockout
Bloom enhancers to improve fruit and flower set
Enzymatic additives that support root health and nutrient uptake
Organic plant booster options (fish and seaweed-based) for natural, gradual growth support
Choosing the right booster comes down to your plant's current stage and growing medium. Vegetative-stage boosters support root and leaf development; flowering-stage boosters like PK additives shift the plant's energy toward bud set. Coco coir growers typically need consistent CalMag, while DWC and NFT growers benefit from root stimulants and enzymatic additives to keep the root zone clean.
