Although Mapito has been around for some time, growers seem to have discovered the benefits of growing on this substrate, especially in recent years. This is not for nothing, because Mapito is firmly structured as a substrate and has an optimal ratio of water and oxygen. This combination forms the basis for very good harvests! Mapito consists of stone wool flakes and coconut fibers. Mapito itself therefore hardly contains food, but the water and the liquid food are stored in it.

Rinse, EC and Ph value
Before we can use Mapito, we have to clean it properly first in order to lower the EC earth. Another important point when growing on Mapito is that we have to keep a close eye on the pH value of the substrate. For successful cultivation on Mapito it is best if we maintain a pH value in the substrate of between 5.3 and 5.8. As normal tap water, for example, would have a pH value of 7.5, this means that we have to lower the pH value of the tap water. By using pH minus and applying the correct dosage, we can get the pH value at the ideal value. Regular measuring and checking is recommended. Often there is a lot of information on the Internet about the pH value over the tap water in your area.

At the start of growing on Mapito it is important, as with growing on rock wool, that we let the Mapito soak. If you do not do this or do it wrong, chances are that the Mapito will not work as well and will absorb significantly less moisture and release it to the plants. All stone wool substrates (including Mapito) must be soaked before the start of the cultivation. This is done to ensure that the ability of the Mapito to retain water will be increased. This is called the 'capillary effect'. Mapito that has not been soaked in advance does not retain the water sufficiently and therefore does not give plants enough or sufficient to absorb moisture and nutrients from them. You often see such problems with growers who have a remarkable number of cuttings that do not catch on. Incorrect soaking of the Mapito is often the main culprit. The young, often vulnerable, cuttings do not last long. This is also the reason why stone wool mats are often provided with a plastic layer (white cover). In the regular horticulture this plastic cover functions as a breeding box. Moreover, thanks to the plastic cover, the mats can more easily be soaked. If Mapito or rockwool is not soaked before starting breeding, the dry spots will not get wet during the cultivation. The Mapito can not optimally retain moisture. For optimal soaking, keep the Mapito wet for 24 hours. In this way the basis for a beautiful harvest has already been laid!

Cultivation tip
When you fill the flowerpots or nursery trays with Mapito flakes for the first time, make sure you fill the pots or nursery trays to the maximum. By adding as many flakes as possible, you prevent the substrate from collapsing too much, after the flakes have become moist for the first time. Due to the water, the flakes are of course heavier and part of the air is squeezed out. This allows a substrate from Mapito to shrink considerably. By applying a sufficiently thick layer, the substrate will remain sufficiently thick after sagging in order to be able to continue to grow decent plants on it. If the Mapito layer should collapse too much, add extra flakes again, so that the pot is filled optimally.
