Who It’s For

Bloom Yellow Bottles Flower A&B is ideal for growers seeking a dedicated flowering and bloom nutrient to support healthy flower development and productive harvests. Suitable for beginners, experienced hydroponic growers and commercial cultivators, this concentrated two-part fertiliser offers a flexible feeding solution for soil, coco and hydroponic growing systems. Whether cultivating flowering plants in a compact indoor grow tent, a dedicated grow room, greenhouse or larger commercial growing facility, Flower A&B is particularly suited to growers who prefer separate vegetative and flowering nutrient formulations. It is also an excellent choice for those already using Bloom Grow A&B who want to maintain a consistent feeding programme when transitioning into the bloom stage.

How To Use

Use Bloom Flower A&B as the primary base nutrient throughout the flowering stage. Begin using the product when plants transition from vegetative growth into flowering, replacing Bloom Grow A&B where applicable. For photoperiod-sensitive crops, this typically corresponds with the transition to a 12/12 light cycle.

Fill a nutrient reservoir or mixing container with clean water. Add the required quantity of Flower A and mix thoroughly before adding an equal quantity of Flower B. Mix again until the solution is evenly distributed. Never mix concentrated Flower A and Flower B directly together before diluting them in water, as this can cause nutrient precipitation.

The typical application rate is 1–2ml per litre of water per part, with approximately 2ml per litre per part commonly used during the flowering cycle. Actual application rates depend on the growing medium, irrigation system, plant requirements and manufacturer's feeding schedule. Monitor the prepared nutrient solution's pH and EC levels and adjust as appropriate for the crop and cultivation method.

Continue using Bloom Flower A&B throughout the flowering cycle as the foundation of your feeding programme. Compatible Bloom Advanced Floriculture flowering additives, including ULTRA, PHAT, OOZE and FINAL, can be incorporated according to their individual application instructions. Reduce or discontinue the base nutrients during the final flushing stage in accordance with the recommended feeding schedule and crop requirements.
