qualities and growth stages without deviating from
the optimal nutrient solutions. Both with surface and
well water Subtil fertilization matches pH and nutrient
proportion thanks to its flexible and well considered
concept. |

to make mistakes are reduced considerably. The chelates

systems, starting from a simple tank with a volumetric
dosage pump up to full automatic AB-units. |
