ROOTLABS Mineral Grow Mix – Professional Semi Hydro (8L)

ROOTLABS Mineral Grow Mix is a precision-blended inorganic substrate designed for growers who want maximum control over moisture, airflow, and root health.

Built using a carefully balanced combination of LECA, zeolite, and perlite, this mix delivers a highly aerated root environment while maintaining stable moisture availability, ideal for semi-hydroponic and controlled growing systems.

Specification

– Particle Size: 3–8mm blended

– Clean, dust-minimised components

– Inorganic and slow-degradin

– Excellent capillary and drainage balance

Why Use Mineral Grow Mix?

✔ Exceptional root oxygenation
✔ Prevents compaction and root suffocation
✔ Stable moisture retention without overwatering
✔ Ideal for semi-hydro and self-watering setups
✔ Long-lasting and reusable

Ideal For

– Semi-hydroponic growing systems

– Aroids transitioning from soil

– Alocasia and Anthurium

– Orchids (select applications)

– Root rehabilitation and propagation

What Makes It Different

Unlike traditional potting mixes, ROOTLABS Mineral Grow Mix does not break down over time. This allows for predictable watering cycles, reduced risk of root rot, and a cleaner, more controlled growing environment.

FAQ
Is this similar to PON?

ROOTLABS Mineral Grow Mix is comparable in function to mineral substrates like PON, as both are designed to create a highly aerated, controlled root environment using inorganic materials.

However, ROOTLABS Mineral Grow Mix is locally developed and specifically balanced for South African growing conditions, using a blend of LECA, zeolite, and perlite to achieve optimal moisture retention and airflow.

What is the difference between this and PON?

While both serve a similar purpose, there are key differences:

ROOTLABS Mineral Grow Mix uses a chunkier 3–8mm structure, improving airflow and reducing compaction

Designed for stronger drainage control, especially in warmer climates

Built using locally sourced materials, making it more accessible and cost-effective

Slightly more forgiving for growers transitioning from soil

In practical terms: PON is more uniform and fine, ROOTLABS is more breathable and robust.

Can I use this exactly like PON?

Yes, it can be used in the same way:

– Semi-hydro systems

– Self-watering pots

– Passive hydro setups

You may need to slightly adjust your watering frequency depending on your environment and pot type.

Is this better than soil?

It depends on your goal.

Mineral Grow Mix offers:

– More control over watering

– Reduced risk of root rot

– Better airflow to roots

Soil, on the other hand, holds more nutrients naturally but is less predictable over time.

This mix is ideal if you want consistency and control.

Do I need to add fertiliser?

Yes.

Because this is an inorganic substrate, it does not contain nutrients. You will need to use a liquid fertiliser as part of your watering routine.

We reccommend EHG

Can I reuse it?

Yes.

One of the biggest advantages is that Mineral Grow Mix does not break down. With proper rinsing and cleaning, it can be reused multiple times.
