Base Nutrient

FloraPro™ Grow B

FloraPro™ Grow B is used with FloraPro™ Grow A to complete the vegetative base of the FloraPro Liquid Program. Built for propagation and vegetative growth, Grow B helps deliver balanced vegetative nutrition and essential elements as part of a calcium-fortified two-part system. Together, Grow A and Grow B support structural development, rootzone balance, and preparation for the transition into flowering.

FloraPro Grow B (1-2-4) is the B-side component of the FloraPro two-part vegetative base system. When used with Grow A, it helps provide the primary vegetative nutrition and essential micros needed for rapid crop development. This two-part system supports vegetative growth while keeping the feed program simple, consistent, and ready for the generative shift.

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

  • Propagation, Week 1: 7 mL/gal Grow B
  • Vegetative, Weeks 1–3: 12 mL/gal Grow B

Use at the corresponding Grow A rate:

  • Propagation, Week 1: 7 mL/gal Grow A
  • Vegetative, Weeks 1–3: 12 mL/gal Grow 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.

Grow B completes the two-part vegetative base system, helping commercial growers deliver consistent nutrition through propagation and veg. When paired with Grow A, it supports balanced rootzone conditions, vegetative structure, and a cleaner operational workflow. The result is a simplified base nutrient strategy designed for commercial consistency and efficient crop steering.
