This booster has been especially composed for the cultivation on soil. It has a favourable influence on important micro-organisms and bacteria that give soil life a boost and thus help to improve the condition of the plant. This way it provides extra stability and a biological balance in the substrate, causing the development of the root system to increase. In addition to aquatic bacteria this booster also contains essential chelated micro-nutrients. Micro-nutrients are nutrition components that the plant absolutely needs to be able to develop well, but cannot produce itself. This booster therefore ensures that shortages during the growing cycle will not occur quickly. The booster also helps to set the citric acid cycle in motion, so that all the important nutrients are directly converted into energy for the plant.
