Rockwool Growing Medium

Cultiwool Mapito is a high-performance hydroponic growing medium made from fibrous rockwool flakes. Designed to provide the perfect balance of water retention and root-zone aeration, it helps create a stable environment for strong, healthy root development.

This loose rockwool substrate offers excellent structure while still allowing plenty of airflow through the root zone. The result is a growing medium that holds nutrients effectively while ensuring roots stay oxygenated.

Supplied in a convenient 80 litre bag, Mapito is ideal for use in drip irrigation systems and works well as an alternative to coco or clay pebbles.

Key Benefits

• Excellent water and nutrient retention
• High aeration levels support healthy root development
• Stable fibrous structure ideal for hydroponic systems
• Great alternative to coco or clay pebbles
• Easy to work with loose substrate
• Supplied in a large 80L bag

Why Choose Mapito?

Successful growing starts with a healthy root zone. Plants need access to both moisture and oxygen to absorb nutrients efficiently.

Cultiwool Mapito achieves this balance by combining rockwool fibres that hold water with a loose structure that maintains airflow. This helps prevent waterlogging while ensuring roots always have access to moisture and nutrients.

The result is a stable root environment where plants can establish quickly and grow vigorously.

Ideal for Hydroponic Systems

Mapito is particularly popular in drip irrigation systems where growers need a substrate that drains well but still retains nutrients.

It can be used in pots, slabs or containers and behaves similarly to coco or clay pebbles while offering excellent moisture management.

How to Use

Fill your pots or containers with Cultiwool Mapito and plant as you would with other hydroponic substrates.

Use alongside a suitable hydroponic feeding schedule and irrigation system. The medium will hold onto water and nutrients while allowing excess solution to drain freely.

Top Tip

Because Mapito drains well, frequent light irrigations work best. This helps maintain the perfect balance of moisture and oxygen in the root zone for consistent plant growth.
