MAB Grow 2-6mm (Soil Replacement)

What is MAB Grow 2–6mm and what is it made from?

MAB Grow 2–6mm is a 100% mineral-based growing media made from horticultural-grade aeration stone. The 2–6mm particle size is ideal for most pots and plants, offering a clean, stable alternative to soil or LECA for passive hydro and self-watering systems.

How is MAB Grow 2–6mm different from soil, LECA, or PON?

Unlike soil, MAB Grow doesn’t compact, rot, or attract fungus gnats. Compared to LECA, it’s smaller, more absorbent, and helps reduce pH swings. It functions similarly to PON but with more airflow and less weight.

Does MAB Grow 2–6mm hold water or dry out quickly?

It holds moisture inside while staying airy. The surface may dry faster than soil, but internal hydration remains. Use the colour shift—from dark to light—as a visual cue for watering.

What types of plants grow well in MAB Grow 2–6mm?

It suits most houseplants, including aroids, hoyas, alocasias, orchids, herbs, and veggies. It can be used indoors or outdoors, as long as watering and nutrients are adjusted for your conditions.

Can I plant directly into 100% MAB Grow 2–6mm?

Yes—just clean about 90% of the old soil off the roots before transplanting. Some plants may pause or drop leaves during adjustment, but most bounce back well in active growing conditions.

Do I need to fertilise when using MAB Grow 2–6mm?

Yes—this media doesn’t contain nutrients. Use a complete liquid fertiliser weekly during active growth. Hydro-friendly nutrients work best. Cal-Mag is often used, while organics can attract pests in reservoirs.

Is MAB Grow 2–6mm reusable?

Absolutely. Rinse off debris, remove old roots, and sanitise if needed. Pre-soaking in a mild nutrient solution can help plants establish faster after reusing.

What pots work best with MAB Grow 2–6mm?

It works in mesh, nursery, or cache pots, and excels in self-watering setups. Keep the reservoir shallow—enough to wick moisture, but not flood the roots. Avoid using it just as a top-dress over heavy soil.

Does MAB Grow 2–6mm cause algae or salt buildup?

Algae can form on the surface if exposed to light, moisture, and nutrients. Salt buildup may happen if feeding is too heavy or unflushed. Occasional flushing with plain water solves both issues.

Is MAB Grow 2–6mm safe and beginner-friendly?

Yes—it’s clean, pest-free, and great for overwaterers. It supports beneficial microbes and doesn’t stain or damage surfaces when used with trays. Just remember to fertilise regularly and clean soil off roots when switching.
