Who This Is For

  • You are switching to powder nutrients because liquid concentrates are too expensive to ship in bulk.
  • You are adopting technical-grade minerals because cheaper salts leave a residue that clogs your fertigation lines.
  • You are simplifying your mix because managing a half dozen bottles leads to frequent dosing errors.

What We Found

  • This technical-grade powder stays in solution better than consumer brands, which saves your pump from wear and tear.
  • We noticed the 25lb bag is the sweet spot for commercial ops wanting to switch from heavy, expensive liquid totes.

What Users Say

  • Growers using injection systems say they stopped seeing nutrient drift across the bench after switching to FloraPro.
  • Commercial teams report that moving to this powder reduced their shipping costs significantly compared to liquids.

General Hydroponics FloraPro Bloom 25lbs

Transitioning crops from vegetative stages using General Hydroponics FloraPro Grow to flowering stages demands precise nutrient formulation to maximize yield and quality. FloraPro Bloom delivers a technical-grade 7-12-27 NPK ratio engineered specifically for the flowering phase in commercial production systems, ensuring your high-value crops receive the potassium-heavy nutrition they need when it matters most.

FloraPro Bloom isn't a consumer-grade product adapted for commercial use. It's a purpose-built flowering nutrient designed from the ground up for fertilizer injection systems in large-scale operations. The formula uses technical-grade minerals that fully dissolve in solution, preventing the clogging and inconsistency that plague commercial growers. This complete water solubility ensures every plant receives identical nutrition across your entire operation, whether you're growing in rockwool, coco, or water culture.

As part of the four-product FloraPro system, FloraPro Bloom pairs with FloraPro Calcium + Micros during the flowering stage to deliver the precise potassium and phosphorus ratios that drive flower development and resin production. The two-stage methodology eliminates guesswork—you'll use just two of four products per growth phase, making large-scale feeding programs both scalable and repeatable for consistent results harvest after harvest.

FAQ

When should I switch from FloraPro Grow to FloraPro Bloom?+

Switch to FloraPro Bloom when your plants enter the flowering phase, typically triggered by changing photoperiods or when plants naturally transition from the FloraPro Grow stage. Use FloraPro Bloom paired with FloraPro Calcium + Micros throughout the flowering stage, then transition to FloraPro Late Bloom for the final ripening phase.

Why does FloraPro Bloom have higher potassium than nitrogen?+

The 7-12-27 NPK ratio reflects the nutritional shift plants need during flowering. Higher potassium (27%) drives flower development, resin production, and overall crop quality, while reduced nitrogen (7%) prevents excessive vegetative growth that would compete with flower formation. This ratio is specifically engineered for optimal flowering performance in high-value crops.

Can I use FloraPro Bloom with my existing injection system?+

Yes, FloraPro Bloom is designed from the ground up for commercial fertilizer injection systems. Its complete water solubility ensures it won't clog injectors, drip lines, or emitters. Follow the feed charts for proper dilution ratios based on your system's capabilities and crop requirements.

What's the difference between FloraPro Bloom and Late Bloom?+

FloraPro Bloom is used during the main flowering phase to drive flower development and bulk. FloraPro Late Bloom is used in the final ripening stage with a different nutrient profile optimized for finishing and enhancing final quality. The two-stage flowering approach allows you to fine-tune nutrition for each distinct phase of flower development.

How does technical-grade differ from agricultural-grade nutrients?+

Technical-grade nutrients contain minimal impurities and precise mineral ratios, ensuring batch-to-batch consistency critical for commercial operations. Agricultural-grade nutrients may contain fillers or variable mineral content that can cause inconsistent results across large-scale grows. For high-value crops where quality directly impacts revenue, technical-grade inputs are essential.

Will FloraPro Bloom work in organic growing systems?+

No, FloraPro Bloom is a synthetic fertilizer derived from ammonium nitrate, magnesium nitrate, monopotassium phosphate, and potassium sulfate. It's not certified for organic production. However, it's designed for commercial growers prioritizing consistency, yield, and quality in conventional hydroponic and soilless systems.

What EC range should I target with FloraPro Bloom?+

EC targets vary by crop type and growth stage. The Standard feed chart provides baseline recommendations, while the High EC chart is for growers pushing maximum yields with crops tolerant of higher nutrient loads. Monitor your plants' response and adjust accordingly—General Hydroponics provides both charts so you can dial in the optimal EC for your specific operation.

Do I need to use all four FloraPro products?+

Yes, for complete nutrition through the entire lifecycle. Use FloraPro Grow + FloraPro Calcium + Micros during vegetative growth, then switch to FloraPro Bloom + Ca & Micros during flowering, and finish with FloraPro Late Bloom + Ca & Micros. You'll always use two products together per phase—this two-stage system simplifies large-scale feeding while delivering professional results.
