• Our Feedchart Usage Guide explains how to interpret and use General Hydroponics Pro Feedcharts. It is intended as a companion piece to General Hydroponics Pro feedcharts for FloraPro, Flora Series, Cocotek and Maxi Series.

  • Each set of feed charts illustrates Aggressive, Medium, and Light Feeding recipes.  (For most modern production systems, we recommend the Medium Feed strength).

    Aggressive Feed: Best for larger, multi-topped plants, where planting density is low and crops are irrigated less frequently.  Plant density 0.25-4 per 16 sq ft

    Medium Feed: Suitable for most modern production systems. Best for medium-sized plants and medium planting density, where crops are irrigated frequently. Plant density 4 -10 per 16 sq ft

    Light Feed: Best for smaller plants, grown in high-density layouts and using pulse feed or very high frequency, low-volume irrigation events.  Plant density 11- 20 per 16 sq ft

  • Each feed chart download includes two versions — Weekly & Growth Phase — and you can choose either version based on your needs.  

    Weekly Feed Chart: The weekly version divides each fertilizer recipe by week from the Seedling/Cuttings stage through Harvest. 

    Growth Phase Feed Chart: The Growth Stage versions include fewer recipes geared toward key growth stages, and are intended for large-scale commercial operators who require simplified fertilizer recipe counts for complex fertigation systems.

  • 3-Part Feed Chart: Our 3-Part programs use only the base nutrients in Flora Series: FloraGro®, FloraBloom®, and FloraMicro®. This program is perfect for growers who want to keep it simple, whether they are a large commercial grower trying to simplify their operation, or a first time hobbyist just trying to get their bearings.  

    6-Part Feed Chart: The 6-Part feed charts include six total products: the three base nutrients in FloraSeries®, plus three additional liquid fertilizers supplements: CaliMAGic™, Liquid Koolbloom®, Floralicious® Plus.
