What Are Nutrients and Boosters?
Nutrients and boosters are products used to support plant growth, improve root development and maximise flowering potential. Base nutrients provide the essential elements plants need throughout their lifecycle, while additives and boosters are designed to support specific stages such as rooting, vegetative growth and bloom.
Indoor plants rely on a balanced feeding programme to achieve strong growth and healthy development. Choosing the correct nutrients for your growing method is one of the most important parts of any successful indoor growing setup.
Types of Plant Nutrients and Additives
There are several different types of nutrients and boosters available depending on your setup and the stage of growth:
- Base Nutrients – provide the core nutrients plants need for everyday growth
- Root Stimulators – support early root development and plant establishment
- Veg Boosters – help encourage vigorous vegetative growth
- Bloom Boosters – support flower development and final yields
- Enzymes and beneficial products – help maintain a healthier root zone and nutrient uptake
- pH and nutrient management products – help keep feeding solutions balanced and stable
Using the right combination of products can help plants perform more consistently throughout the growing cycle.
Why Nutrients Matter in Indoor Growing
Plants grown indoors depend on the grower to provide the nutrients they need. Without the right feed, plants can suffer from poor growth, weak roots and reduced yields.
- Supports healthy root and leaf development
- Helps plants maintain vigorous growth
- Encourages stronger flowering and fruiting
- Improves plant health and overall performance
- Helps maximise the results of your indoor setup
Whether you are growing in soil, coco or a fully recirculating hydroponic system, nutrients play a major role in plant performance and final results.
Choosing the Right Nutrients for Your Growing Medium
Different growing media require different feeding approaches. Choosing nutrients that match your setup helps maintain balance and improve uptake.
- Soil nutrients – designed for plants grown in traditional soil mixes
- Coco nutrients – formulated for the unique properties of coco coir
- Hydroponic nutrients – designed for use in water-based growing systems
If you are growing in coco, rockwool or soil, it is important to use nutrients suited to that medium. For growers using advanced systems, our range also supports NFT, DWC, flood and drain and drip irrigation systems.
Nutrients and Indoor Growing Setups
Nutrients work best as part of a complete indoor growing setup. For the best results, pair your feeding programme with the right equipment:
- Grow lights to support plant growth and flowering
- Grow tents and sheeting to create a controlled environment
- Fans, filters and odour control to manage temperature and airflow
- Grow room tools to monitor pH, EC and feeding accuracy
This combination helps create a stable environment where plants can absorb nutrients efficiently and grow to their full potential.

Do I need different nutrients for coco and hydroponics?
Yes, different growing media often require different nutrient formulations to achieve the best balance and uptake.
Why are pH and EC important when feeding plants?
pH and EC help you measure nutrient balance and solution strength, allowing plants to absorb feed more effectively.
