FloraPro™ Grow

FloraPro™ Grow is part of General Hydroponics’ commercial, 2-part, water-soluble base fertilizer system engineered for continuous liquid-feed programs and fertilizer-injection setups. In the vegetative stage, pairing FloraPro™ Calcium + Micros with FloraPro™ Grow delivers stage-specific ratios that help optimize structural/foliar development and build strong roots, stems, and leaves.

Guaranteed Analysis (GA): 10-12-22 N-P-K, 3.5% Magnesium, 4.5% Sulfur.
Derived From: Ammonium nitrate, ammonium phosphate, ammonium sulfate, magnesium sulfate, potassium nitrate.

: When paired with FloraPro™ Calcium + Micros, FloraPro™ Grow supplies stage-specific nutrition for roots, stems, leaves, and structural development during veg.

: FloraPro Grow is the veg-stage “B tank” in the FloraPro program. Paired with FloraPro Calcium + Micros, it provides the NPK and secondary nutrients plants need to build strong roots, stems, and leaves during vegetative growth, creating the structural frame that will later support flowers, fruit, and seed production.

Two-part program: Run Calcium + Micros (all stages) + Grow (vegetative stage). Only two products are used at a time.
Dilution: Fully dissolve in water before feeding. Intended for continuous liquid feed via day tanks, fertilizer injectors, or dosing systems.
Stage application: Use from early veg through late veg/pre-flower; at flower initiation, keep Calcium + Micros and switch Grow → Bloom.
System fit: Works with all media (rockwool, coco, soilless, etc.); designed for commercial hydroponic cultivation and clean operation (highly soluble, quick dissolving).

Frequently Asked Questions

What are the bag size and expected gallon coverage for FloraPro™ Grow?

FloraPro™ Grow is packaged in a 25 lb bag. Depending on the fertigation program, target EC, and dilution rate, one bag can make approximately 2,800 to 6,300 gallons of ready-to-use vegetative nutrient solution.

What is the SOP for mixing an automated commercial stock solution of FloraPro™ Grow?

Fill a clean stock tank to about 70% of final volume with fresh water; reverse-osmosis water is preferred and warm water can speed dissolution. Begin constant mechanical agitation.

Slowly add the weighed FloraPro™ Grow powder. A common commercial stock concentration is 1 lb of fertilizer per gallon of stock. Once dissolved, top off to final volume, cover the tank, and use the stock within 2 weeks.

What is the maximum solubility limit of FloraPro™ Grow, and why is it important?

The maximum recommended solubility is 420 g/L, or 3.5 lb per US gallon. Do not exceed approximately 80% of this maximum when formulating concentrated stock, because excess concentration can cause minerals to salt out, produce uneven feeding, and clog equipment.

How does the FloraPro™ two-part A/B system function during the vegetative phase?

Calcium + Micros (14-0-0) remains in Tank A as the constant nutrient backbone. During vegetative growth, it is paired with FloraPro™ Grow (10-12-22) in Tank B to form a complete, balanced plant food program.

What is FloraPro™ Grow and what is its role in a commercial cultivation system?

FloraPro™ Grow is a high-purity, technical-grade water-soluble dry base fertilizer used in Stock Tank B during vegetative growth. Paired with Calcium + Micros in Tank A, it supplies stage-specific mineral ratios that support strong roots, stems, and foliage.
