General Hydroponics FloraPro Liquid Bloom A, 55 Gallon

FloraPro Bloom A is used with FloraPro Bloom B to form the flowering base of the FloraPro Liquid Program. Designed for flower and finish, Bloom A helps deliver core flowering nutrition and calcium support as part of a two-part system built for high-intensity commercial production. Together, Bloom A and Bloom B support calcium delivery, nitrogen tapering, flower development, and a controlled finish.

What It Does

FloraPro Bloom A (3-0-1) is the A-side component of the FloraPro two-part flowering base system. When used with Bloom B, it helps deliver the nutritional foundation needed for flowering and finish. The Bloom A/B system uses multiple calcium sources, including a nitrogen-free source, to help sustain calcium delivery later into flower while the program shifts toward a lower-nitrogen finish.

How To Use It

Use FloraPro Bloom A with FloraPro Bloom B as part of a continuous liquid feed program for hydroponic use only. Do not use Bloom A 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 A rates from the FloraPro Liquid Feed Program:

• 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

Use at the corresponding Bloom B rate:

• 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

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

Flowering nutrition needs to support generative development without carrying unnecessary nitrogen through the finish. Bloom A helps form the two-part flowering base system that sustains calcium delivery while allowing Bloom rates to taper as PK+ increases. This gives commercial growers a structured way to support flowering, ripening, and finish quality through a repeatable liquid feed program.

How To Use This Product

Part of the Two-Part Bloom Base

FloraPro Bloom A is designed to be used with FloraPro Bloom B as the flowering base nutrient system in the FloraPro Liquid Program. Together, they deliver core flowering nutrition from early flower through finish.

Calcium Support Through Flower

Bloom A contributes to the FloraPro Liquid Program's calcium-fortified flowering strategy, helping sustain calcium delivery as the crop moves deeper into flower and finish.

Supports the Nitrogen-Tapering Strategy

As Bloom A/B rates decrease and PK+ rates increase, the FloraPro Liquid Program shifts nutrition toward flower formation, bulking, ripening, and finish quality while reducing nitrogen delivery.
