How to apply General Hydroponics ProRelease Container Ferilizers

Method #1 Incorporate the CRF fertilizer into your growing media prior to planting.

  • Blend into growing media in a manner to ensure uniform distribution of fertilizer particles / prills. Do not over-mix as doing so could damage the fertilizer coating and also break down growing media structure.
  • Following incorporation, growing media should beused within two to four weeks.
  • Water thoroughly immediately after planting.
  • Method #2 Top-dress or broadcast the CRF fertilizer on the top of the growing media.

    • For top-dress applications, spread fertilizer evenly on the container surface.
    • Avoid piling fertilizer in one spot or piling fertilizer directly against plant stem.
    • Irrigate immediately after top-dress applications.
