    HESI Phosphorus Plus is used in combination with Hesi Bloom Complex in the second half of the flowering phase. During flowering, the plant develops an increased need for phosphorus and potassium. Using Phosphorus Plus, we give plants the right means at the right moment: phosphorus for the extra formation of flowers and potassium for fast transport to the flowers. Hesi soil nutrition has been balanced to the ratios in the soil environment and ensures that the plants are taken care of in an optimal manner. Thanks to the use of high-quality ingredients, the plants absorb all substances offered to them, so that no residues are left behind. With Phosphorus Plus the formation of the flowers is more powerful! HESI Phosphorus Plus is also suitable for all forms of phosphorus or potassium deficiency.

It is very useful in the early stages of growth to encourage healthy root development.

    The nitrogen that is used in TNT is 100% organic. The organic nitrogen compounds have no EC value because they are no salts. Therefore young plants are loaded with a minimum of salts, which creates ideal growing conditions, it appears that TNT Complex has a low EC value, but its degree of effectiveness is very high.
