BAC Organic PK Booster – Organic Flower & Bloom Enhancer
BAC Organic PK Booster is a premium organic flowering additive developed to maximise flower quality, aroma, flavour and overall harvest performance. Designed to complement BAC Organic Grow and BAC Organic Bloom, this powerful bloom booster supplies organic phosphorus, potassium, trace elements and natural sugars that work together to support vigorous flower development throughout the flowering stage.
During bloom, plants require increased levels of phosphorus and potassium to produce larger, denser flowers and higher-quality fruit. BAC Organic PK Booster has been specifically formulated to stimulate natural sugar production within the plant, enhancing flavour, fragrance and resin production while improving the overall appearance and quality of the final harvest.
Unlike conventional PK additives, this product works in harmony with the living biology already present in organically managed growing media. The rich blend of organic trace elements and natural sugars provides an excellent food source for beneficial soil bacteria and mycorrhizal fungi, helping create a thriving root zone where nutrients become more available to plants. This biological activity encourages healthier roots, stronger flowering and improved nutrient efficiency throughout the bloom cycle.
The formula also contains Yucca extract, a natural wetting agent approved by the Soil Association. Yucca improves water penetration throughout the growing medium, allowing nutrients to spread more evenly and reach the root system more efficiently. Combined with premium organic ingredients including alfalfa meal, sugar molasses, kali vinasse and stone meal, BAC Organic PK Booster delivers outstanding flowering performance while supporting healthy soil biology.
Suitable for organic soil and biologically active growing systems, BAC Organic PK Booster is ideal for growers looking to maximise crop quality naturally while maintaining a healthy microbial environment.
