Frequently asked questions

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.  

  • CALiMAGic™ is a concentrated blend of readily available calcium and magnesium, assists fast growing plants by preventing secondary nutrient deficiencies. 
  • Liquid Koolbloom® is formulated to provide a boost to the nutrients necessary for maximum floral yields. 
  • Floralicious® Plus contains essential plant nutrients that are known to encourage essential oil production and improve plant vigor. 

10-Part Feed Chart: Our custom performance plan includes ten total products: the six products in the Pro Performance charts, plus four additional supplements — used individually or together — to fine tune your recipe to address any remaining challenges with your plants and their growing environment.  

  • ArmorSi™ adds Silica to strengthen and help protect plants from stressful conditions.
  • Rapidstart™ is a proprietary blend of plant nutrients to promote superior root growth and development.  
  • Ripen® contains essential plant nutrients needed for flower maturation to support abundant flowering, with greater oil and fragrance production,
  • FloraKleen® helps flush out accumulated salts from the rootzone.

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.

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
