In the professional horticulture, the top priority is safety. To produce a safe substrate, we need safe raw materials.
It is for that reason that the information of your base materials should be clear:

  • Is the material uniform?
  • What is the chemical analysis?
  • What is the physical analysis?
  • Are there weeds in your raw material?
  • Is the material stable or does it break down easy?
  • What is the availability?
  • How proper is the production site?
