General Hydroponics® FloraPro™ Late Bloom – 5 lb

General Hydroponics FloraPro Late Bloom (0-24-26) is a dry, water-soluble fertilizer formulated specifically for commercial cultivation. Applied during the late flowering stage, it delivers concentrated phosphorus and potassium to support dense flower development and finish. It is designed as part of the FloraPro product system, working alongside FloraPro Grow and FloraPro Bloom to form a complete fertilizer program.

FloraPro Late Bloom Specifications

Key technical specifications for General Hydroponics FloraPro Late Bloom 5 lb, based on manufacturer data and canonical product information.

Why Choose FloraPro Late Bloom

FloraPro Late Bloom addresses a specific need in the flowering cycle: the transition from peak bloom into the final ripening and finishing phase. During this window, most growers scale back nitrogen entirely and push phosphorus and potassium to drive flower density and development. FloraPro Late Bloom’s 0-24-26 ratio reflects this precisely—no nitrogen, high phosphorus for flower initiation and energy transfer, and elevated potassium for cell integrity and overall plant health.

• Zero nitrogen in late bloom. By removing nitrogen from the late-bloom feed, FloraPro Late Bloom avoids forcing vegetative growth at a stage when the plant’s energy should be directed entirely toward flower maturation.
• High phosphorus (24%) to support flower development. Phosphorus plays a central role in ATP production and nutrient transport during reproductive growth—FloraPro Late Bloom delivers it at concentrations appropriate for the finish phase of commercial cultivation.
• Elevated potassium (26%) for plant structure and quality. Potassium supports cell wall integrity, enzyme activation, and water regulation. At 26%, FloraPro Late Bloom provides the potassium load that finishing plants typically require.
• Formulated for commercial scale. The 5 lb dry, water-soluble format reduces shipping weight compared to liquid concentrates and is sized for professional growers running recirculating or drain-to-waste systems at scale.
• Part of a complete fertilizer system. FloraPro Late Bloom is designed to follow FloraPro Bloom in the nutrient schedule, fitting into an integrated program rather than requiring growers to mix and match from unrelated product lines.

Best Uses for FloraPro Late Bloom

FloraPro Late Bloom is intended for the final flowering phase of the growth cycle in commercial or large-scale hobby cultivation. It works best when the grower is already using the FloraPro product system, though its straightforward 0-24-26 profile makes it compatible with other structured nutrient programs that call for a phosphorus- and potassium-dominant late-stage feed.

• Recirculating hydroponic systems — NFT, DWC, and flood-and-drain setups where water-soluble dry nutrients dissolve cleanly and allow precise EC management.
• Drain-to-waste coco or rockwool grows — The dry powder format doses predictably in high-volume irrigation runs typical of commercial coco cultivation.
• Final 2–4 weeks of flower — Applied once the plant has fully committed to flower production and nitrogen requirements have dropped to near zero.
• Commercial flower crops and high-value annuals — FloraPro Late Bloom was developed with commercial cultivators in mind; the 5 lb pack size is appropriate for medium-scale operations.
• Programs using the full FloraPro system — Works in sequence after FloraPro Grow and FloraPro Bloom to complete the recommended nutrient schedule from vegetative growth through harvest.

Growers pairing this with organic inputs may also want to explore Earth Juice Hi-Brix Molasses as a carbohydrate supplement during the finish phase, or consider Down to Earth Crab Meal for phosphorus support in soil-based systems running alongside synthetics.

Dosing Guidelines

FloraPro Late Bloom is a dry water-soluble fertilizer. Dissolve the measured dose in water before adding to your reservoir or irrigation system. General guidance for water-soluble dry nutrients in hydroponic cultivation:

• Pre-dissolve in warm water — Add the measured powder to a small volume of warm water and stir until fully dissolved before introducing it to your main reservoir. This prevents undissolved particles from settling in lines or emitters.
• Target EC range — Monitor your reservoir or runoff EC throughout late bloom. Adjust the dose up or down to stay within your strain’s target EC range for the finish phase. Specific dose rates are published in the FloraPro product system feeding schedule.
• pH adjustment — After mixing, verify reservoir pH and adjust to your system’s target range (typically 5.8–6.2 for most hydroponic media) before irrigating.
• Transition timing — Switch from your peak-bloom formula to FloraPro Late Bloom when flowers have fully formed and the plant no longer shows signs of nitrogen demand. For most crops, this is approximately 2–3 weeks before planned harvest.
• Use within the FloraPro system — For best results, follow the complete FloraPro feeding schedule. Using FloraPro Late Bloom in isolation without the complementary products in the system may require supplemental calcium and magnesium depending on your base water and media.
