FloraPro Powders: Water-Soluble Hydroponic Nutrients

FloraPro Powders are dry, water-soluble base fertilizers for hydroponic and continuous liquid-feed programs. The program pairs Calcium + Micros with stage-specific Grow or Bloom products, with Late Bloom available for programs that specify it.

Compare the components below and follow the powder feeding chart for your delivery method. These products belong to a combined program; an individual bag is not a complete stand-alone feeding system.

Quick Start

How to Use FloraPro Powders

  • Two-part system (A/B):
  • FloraPro™ Calcium + Micros is used throughout the life of the plant.
  • Pair Calcium + Micros with FloraPro™ Grow during the growth (vegetative) stage, and with FloraPro™ Bloom during the bloom (flowering) stage to address stage-specific needs.
  • Completeness: Each part of the FloraPro™ system must be used with another (Micro + Grow, Micro + Bloom) to be a complete nutrient system.
  • Water-soluble & injector-ready: Designed from the ground up for fertilizer injection systems; highly soluble for quick dissolving with no clogging of drip emitters or irrigation lines—works with any dosing system.
  • Program fit: Intended for continuous liquid-feed programs.
  • Bag format: 25 lb bag size enables growers to mix commercial-sized feed tanks easily.
  • Coverage: Optimized formulas provide critical essentials in just three bags; one 25 lb bag makes ~2,800–6,300 gallons of solution (good for the bottom line).

Tips & Tricks

How to create a stock concentrate solution:

  1. Fill a clean stock tank to ~70% with fresh water (warm water dissolves faster).
  2. Agitate (paddle mixer or equivalent).
  3. Slowly add the weighed FloraPro fertilizer to hit your target concentration (typical is 1 lb per gallon of stock).
  4. Top to final volume; cover and store cool/dry, out of sun. Use properly stored concentrate within ~2 weeks.

How batch feed FloraPro:

Two common methods:

  • Direct addition (day tanks): Dissolve FloraPro directly into your ready-to-use veg or bloom day tanks (grams/L or grams/gal per GH charts). Pre-dissolve in a smaller container first, and never mix FloraPro products together while concentrated.
  • Concentrate tanks + injectors: Make A and B stock concentrates (see above), then inject to day tanks or inline to the crop at your chosen ratio (e.g., 1:100 or 1:200).
