£4.95

A 2-1-4 B-vitamin, kelp and humic acid biostimulant designed to support strong stems, vigorous growth and greater resilience to environmental stress.

Advanced Nutrients B-52 is a concentrated plant biostimulant designed to support crops through demanding periods of vegetative growth and flowering. Its formula combines a readily available B-vitamin complex with kelp, humic acid and essential plant nutrients, giving growers more than a straightforward vitamin supplement.

B-52 is particularly useful where strong vegetative development and sturdy plant structure matter. Its combination of B vitamins and kelp supports healthy plant development, while humic acid helps support nutrient uptake and microbial activity around the root zone.

The compact 250ml bottle is ideal for smaller reservoirs, propagation areas and growers wanting to introduce B-52 into their feeding programme without buying a larger container. At the recommended 2ml/L application rate, one 250ml bottle provides enough concentrate for approximately 125 litres of nutrient solution.

What is Advanced Nutrients B-52 suitable for?

B-52 is designed for growers who want to support plant structure, vigorous development and resilience throughout key stages of the crop cycle. It can be introduced during propagation and establishment where appropriate, then used throughout vegetative development.

During flowering, the Advanced Nutrients programme pauses B-52 around the initial transition and early flower-setting stage before bringing it back once flowering is established. From there, it can be used through active and later flowering before being withdrawn for the final flush.

B-52 is suitable for indoor and outdoor growing, hydroponics, coco coir, regular watering and irrigation systems. It can also be incorporated into aeroponic, drip irrigation, nutrient film technique (NFT), flood and drain and deep water culture (DWC) systems.

How to use Advanced Nutrients B-52

Add B-52 at 2ml per litre of nutrient solution throughout vegetative growth. During flowering, pause application through the initial transition and early flower-setting stage, then resume at 2ml/L once flowering is established. Continue through the main flowering period and discontinue for the final flush.

For 5L of nutrient solution, use 10ml. For 10L, use 20ml. For 25L, use 50ml. For 50L, use 100ml. For 100L, use 200ml.

A full 250ml bottle provides enough B-52 for approximately 125 litres of nutrient solution at 2ml/L.

B-52 is a biostimulant and supplement rather than a complete base nutrient. Use it alongside an appropriate base feeding programme according to the crop's nutritional requirements.
