Exact Air

Changing from the bottom up

Thanks to the Gradient Technology, the increase in the density of the stone wool is ‘changing’ from bottom to top. This gives a more even distribution of water content, EC, pH and oxygen. Exact Air has less water roots and good root distribution through the whole slab.


  • Superior oxygen levels especially in the bottom 2.5cm of the slab
  • Less water roots and more air roots because of higher oxygen levels
  • Total slab use with fantastic root distribution and re-saturation
  • Can be used with a wider range of dose sizes and irrigation strategies
  • Good control during decreasing day length and difficult growing conditions
  • Vegetative and generative steering
