TNT Complex is a very powerful growth fertiliser, which is gentle to the plants. The nitrogen that is used in Hesi TNT Complex is 100% organic (Urea).
Organic nitrogen compounds have no EC value because they are not salts, but they do contain a high percentage of nitrogen. Therefore young plants are loaded with a minimum of salts, which creates ideal growing conditions. So, it appears that Hesi TNT Complex has a low EC value, but its degree of effectiveness is very high. Hesi TNT Complex contains all necessary nutrients and has been enriched with many vital components (vitamins, amino acids, plant active sugars) which guarantee a successful growth. Plants that are treated with Hesi TNT Complex develop a large number of growing points and become strong and powerful with a healthy green colour. Never overdose with Hesi TNT Complex, because this will cause the plant to grow too high and it will then consume too much energy for the transport of the roots to the tops at the end of the cycle.
