GROGREEN SUBTIL
Well considered
  Subtil formulations exist for a wide variety of water 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.
For Professionals
  The Subtil range is based on the latest optimal nutrient solutions for substrate grown crops.
Urea free
  Urea based formulations are undesired for substrate cultures. Subtil is free of urea nitrogen
Foolproof
  Preparing the stock solution is simple and the chances to make mistakes are reduced considerably. The chelates used provide a pH stability up to 7,5.
Simple
  Subtil can be applied using various fertilizer dosage systems, starting from a simple tank with a volumetric dosage pump up to full automatic AB-units.
Example: Medium hard water
  Part of the required calcium is present in the water. The missing nitric nitrogen is complemented with nitric acid. At the same time the nitric acid neutralizes bicarbonate and optimizes pH-level.
 
Foolproof solution for substrate cultivation
Ensuring the correct amount of the right nutrients is no easy task. Common practice is to use straight fertilizers. For smaller surfaces, straight fertilizers are not always practical. Application of NPK fertilizers offers an alternative. Most common formulations however, are not fine tuned to match the needs of substrate cultures. Excess or shortage of plant nutrients often results into production and quality losses.
Subtil offers a convenient and foolproof solution to fertilize substrate grown crops.
