How to Submit a Leaf and Water Analysis

Leaf and Water Analysis

Water quality is an important component of your hydroponic production system. Water is used by the plants and is a vehicle by which all outside materials are taken into the plant.

Water qualities can vary considerably from area to area.

  1. Collect a minimum of 16 ounces of water in a clean container.
      - An empty plastic water bottle works well.
  2. Let the source water run for a few minutes before collecting the sample.
  3. No more than a tiny air bubble should be allowed to remain in the container.
  4. Ship to the lab and include the submission form and the payment. (see below for details)
