Pelemix’s coir — cocopeat is an excellent media for roots development. Therefore the volume of substrates / growing media is relatively small (compared to soil and other soilless medias).
Since the volume is relatively small it is very important for roots to equally develop within all the media.
The easiest way to achieve uniformity in the coir — cocopeat is by applying water in a way that the water / air ratio and the E.C. levels in the coir- cocopeat remain the same.
Pelemix strongly recommends applying a slow flow rate dripper every 20 cm (or less).
