Mapito consists of rock wool flakes and coconut fibres. Mapito itself therefore hardly contains any nutrition, but it stores water and liquid nutrition.

Although Mapito has been around for some time, growers seem to have discovered the advantages of growing on this substrate, especially in recent years. This is not without reason, as Mapito as a substrate has a solid structure and an optimal water and oxygen ratio. This combination forms the basis for very good harvests! Mapito consists of rock wool flakes and coconut fibres. Mapito itself therefore hardly contains any nutrients, but water and liquid nutrients are stored in it.

Flushing, EC and Ph-value
Before we can use Mapito, we need to rinse it well to lower the EC soil. Another important point when growing on Mapito is to keep a close eye on the pH value of the substrate. For successful growing on Mapito, it is best if we maintain a substrate pH of between 5.3 and 5.8. Since normal tap water, for example, would have a pH of 7.5, this means we need to bring down the pH of the tap water. By using pH-min and applying the right dosage, we can get the pH value to the ideal value. Regular measuring and checking is recommended. You can often find a lot of information about the pH value of your local tap water on the Internet.

Soaking
When starting to grow on Mapito, just like when growing on rock wool, it is important to soak the Mapito. If you don't do this or do it wrong, chances are the Mapito will not work nearly as well and will absorb significantly less moisture and give it to the plants. All rockwool substrates (including Mapito) should be soaked before starting to grow. This is done to ensure that the Mapito's ability to retain water will be increased. This is called the 'capillary action'. Mapito that is not soaked beforehand does not retain water sufficiently and therefore does not allow the plants to absorb moisture and nutrition from it.

You often see such problems with growers who have a conspicuous number of cuttings that do not take. Not soaking the Mapito or soaking it incorrectly is often the big culprit. The young, often fragile cuttings do not last long because of this. This is also why rockwool slabs often have a plastic layer (white cover). In regular horticulture, this plastic cover functions as a growing container. Moreover, the plastic cover makes it easier to soak the mats completely. If Mapito or rockwool is not soaked before starting cultivation, the dry spots will not get wet during cultivation. The Mapito cannot then retain moisture optimally. For optimum soaking, it is best to keep the Mapito wet for 24 hours. This way, the basis for a good harvest has already been laid!

Growing tip
When you fill your flowerpots or nursing trays with Mapito flakes for the first time, make sure you fill them to the brim. By putting in as many flakes as possible, you prevent the substrate from collapsing too much after the flakes have become damp for the first time. The water obviously makes the flakes heavier and forces some of the air out of them. This can cause a Mapito substrate to shrink considerably. By applying a sufficiently thick layer, the substrate will remain thick enough to continue growing plants on it. Should the Mapito layer still shrink too much, add extra flakes again, so the pot is filled optimally.
