For Aqua systems
How are Canna Hydro and Canna Aqua different?
Canna Hydro fertilizers are designed for open and run-to-waste
systems, where the watering does not circulate, but drains away. Rockwool is
most often used as a medium.
Canna Aqua fertilizers are intended exclusively for
recirculation systems, such as NFT or Wilma. The unique composition ensures
that the pH value of the dressing remains stable in the long
term.
