As with fertilizers for soil-based gardening, nutrient levels in a hydroponic system must be matched to the plant being cultivated. The hydro gardener must also maintain nutrient solution pH levels conducive to plant nutrient uptake. Devices which monitor the pH and electro-conductivity of the solution being used let the gardener know when adjustments to solution parameters are necessary.
Garden Geeks Plant Info
Electro-Conductivity (EC) or Conductivity Factor (cF) can be expressed as either millisiemens (mS), cF or parts per million (ppm).
Example: 1mS = 1EC = 10cF = 700ppm
The pH and Electro-Conductivity values specified here are given as a broad range. It should be noted that different seasons and climate will alter the needs of your plant. As a general rule, in cooler grow rooms, the plant requires higher nutrients; with warmer rooms, the plant requires lower levels of nutrients.
Nutrient Strength Categories: L = Low M = Medium H = High
