Why Are Hydroponic Additives Important?
While base hydroponic nutrients provide essential nutrition, hydroponic additives are what truly unlock a plant’s full potential. These specialised products are designed to target specific aspects of growth, from root development and nutrient uptake to flowering, terpene production, and overall plant resilience.
At TG Hydroponics, our additives range includes over 350 products from trusted brands such as root stimulators, bloom boosters, enzymes, microbial inoculants, and plant enhancers.
Products like root enhancers, microbial additives, and PK boosters play a critical role in improving plant performance throughout each stage of the growth cycle. Whether you're focused on stronger vegetative growth or maximising flowering output, the right additive can make a noticeable difference in results.
Used alongside your base nutrients and lighting setup, additives help create a complete, optimised feeding program for consistent, high-quality yields.

Bloom Boosters & PK Additives
Flowering additives such as PK boosters are designed to increase flower size, density, and yield. These products supply additional phosphorus and potassium during the flowering phase, helping plants reach their full productive potential.
-
Enzymes & Plant Health Enhancers
Enzyme-based additives break down organic matter and improve nutrient availability, while plant health enhancers support resilience and recovery. Products like enzyme solutions and plant tonics help maintain a clean, efficient root zone.
-

Vegetative-stage additives promote faster growth, stronger stems, and lush foliage. These products are ideal for establishing a solid foundation before transitioning to flowering.
