What is Mapito?

It is a special mixture of rockwool and PU flakes that provides excellent moisture holding and proper drainage. It has the absorption capability of rockwool and the drainage provided by pu flakes. It is also compaction resistant which assures good root growth eventually leading to larger plants.




Mapito is one of the most popular growing mediums outside of the United States. It provides a basis for excellent harvests. It is recommended for all pot based systems from hydroponics to soil-less, outdoor and indoor. It is one of the best growing mediums for beginners to experts.

Mapito is a solid structure medium. It retains water and provides oxygen to growing roots. With this proper ratio, plants thrive. You will have top shelf results and will help your garden to reach its true maximum potential.

Before using Mapito, we recommend pH balancing it to around 5.5. The rockwool in Mapito is neutral, but plants like a slightly acidic environment. Adjust the pH of your water to 5.5 by using products such as pH Down or pH Up. Soak Mapito for about 1/2 hour. As an optional step afterwards you can flush Mapito with water combined with nutrients.
Mapito has some excellent benefits over conventional mediums
- Very inert and therefore does not attact unfriendly organisms such as bugs
- Holds an incredible amount of water and retains it
- Holds a lot of air even when saturated
- Clean, convenient and reusable (check out how to)
- Never impedes the development of roots
PU are polyurethane flakes. This material is very similar to foam, but designed for the horticultural and gardening industry. It adds structure to mapito and provides a lighter medium for increased oxygen absorption.
