FloraPro Powders

FloraPro™ Late Bloom $95.91 USD
FloraPro™ Grow from $40.25 USD
FloraPro™ Calcium + Micros Hydroponic Fertilizer $84.88 USD
FloraPro™ Bloom from $40.25 USD

FloraPro™ is General Hydroponics’ water-soluble, two-part base program built for continuous liquid-feed at commercial scale. Calcium + Micros runs in one tank all cycle; pair it with Grow in veg and Bloom in flower to hit stage-specific ratios. Late Bloom adds a zero-N option for finish. Formulas are highly soluble for clean injector and day-tank use, made with technical-grade inputs and lot-tested to label guarantees. No fillers. No dyes. Just the essentials—balanced, repeatable, and easy to deploy in any modern hydroponic workflow. FloraPro™ keeps programs simple—three core products, two in use at a time, consistent turn, and clear positioning for controlled-environment growers. Open the bag, dissolve, dose. The ratios do the heavy lifting—from rooting through finish—so you can focus on canopy, not chemistry.

  • Water-Soluble Fertilizer designed for commercial hydroponic cultivation and continuous liquid-feed programs.
  • FloraPro™ is a base fertilizer that provides plants the essential nutrients they need to grow and is used throughout the life of the plant.
  • It’s a simple system with only three products; only two products are used at one time, making it perfect for a dual-tank system.
  • Water-soluble (intended to be diluted in water and then fed to plants). Additional detail is available in the Product Usage Guide and Technical Bulletin for WSF.
  • Specifically designed for commercial growers and formulated for high-value production crops where results and consistency are paramount.
  • Precise ratios derived from R&D; formulated with the amounts of phosphorus, potassium, sulfur, and other essentials that controlled-environment crops require.
  • Unique formulation and manufacturing ensure consistent nutrient ratios and a balanced nutritional formula with high-quality inputs (no fillers, no added dyes; technical-grade nutrients).
  • Every lot is lab-analyzed to meet label guarantees.
  • Works with all growing media options but designed for commercial hydroponic growing.
  • Tested for compatibility with Hawthorne Gardening Company specialty nutrients (Pro Performance pack and customized performance series).

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).
