General Hydroponics FloraPro Liquid Bloom B, 55 Gallon

FloraProâ„¢ Bloom B is used with FloraProâ„¢ Bloom A to complete the flowering base of the FloraPro Liquid Program. Built for high-intensity commercial flower and finish, Bloom B helps deliver N-P-K, calcium, and micronutrient support as part of a two-part liquid system. Together, Bloom A and Bloom B provide the core flowering base that works with PK+ to support generative development and a controlled finish.

What It Does

FloraPro Bloom B (1-5-5) is the B-side component of the FloraPro two-part flowering base system. When used with Bloom A, it helps provide the core flowering nutrition required for heavy-feeding crops. The Bloom A/B system is designed to support flower formation, calcium delivery, and the FloraPro Liquid Program's shift toward lower nitrogen delivery later in flower.

How To Use It

Use FloraPro Bloom B with FloraPro Bloom A as part of a continuous liquid feed program for hydroponic use only. Do not use Bloom B as a standalone complete base nutrient. Normal feeding range is up to 18 mL/gal, depending on growth stage. Consult the FloraPro Liquid Feed Program for complete recommendations.

Recommended Bloom B rates from the FloraPro Liquid Feed Program:

• Early Flower, Weeks 1–3: 14 mL/gal Bloom B
• Mid Flower, Weeks 4–6: 13 mL/gal Bloom B
• Late Flower, Weeks 7–8: 8 mL/gal Bloom B
• Finish, Week 9: 4 mL/gal Bloom B

Use at the corresponding Bloom A rate:

• Early Flower, Weeks 1–3: 14 mL/gal Bloom A
• Mid Flower, Weeks 4–6: 13 mL/gal Bloom A
• Late Flower, Weeks 7–8: 8 mL/gal Bloom A
• Finish, Week 9: 4 mL/gal Bloom A

Adjustments may be needed based on environmental conditions, water quality, individual grow structure, and use of additional products. Feed programs are recommendations and a starting point; actual results may vary.

Why It Matters

Bloom B completes the FloraPro two-part flowering base system. Used with Bloom A, it helps commercial growers maintain flowering nutrition while the feed program shifts toward generative support and finish. The paired Bloom A/B system gives facilities a repeatable way to support flower development, calcium delivery, nitrogen tapering, and operational consistency.

How To Use This Product

Completes the Bloom A/B System

FloraPro Bloom B is designed to be used with FloraPro Bloom A. Together, they form the two-part flowering base nutrient system used from early flower through finish.

Built for Flowering Demand

Bloom B helps deliver core flowering nutrition as part of a high-intensity commercial feed program. Used with Bloom A, it supports flower formation, ripening, and finish.

Works with PK+ in Flower

The Bloom A/B system is designed to work with FloraPro PK+. As Bloom rates taper and PK+ rates increase, the program supports P, K, and S delivery while reducing nitrogen contribution through the finish phase.
