Full Spec A/B is a high-performance base nutrient formula designed to provide the complete range of macro and trace elements required for vigorous vegetative growth and strong floral development. Engineered using scientific data, crop analysis and advanced mineral chemistry, Full Spec A/B delivers a precise nutrient profile tailored to the demands of high-performance cultivation.
Developed in collaboration with Sostanza, the Full Spec nutrient line was formulated by horticultural scientists and experienced commercial growers with backgrounds in some of Canada and Europe’s most advanced cannabis production facilities. Drawing on years of crop monitoring, leaf tissue analysis and real-world cultivation data, the formula was refined across more than one hundred cannabis cultivars grown in multiple cultivation systems and growing media.
This ultra-soluble, concentrated A/B formula contains optimised minerals, including calcium and magnesium, to support rapid nutrient uptake, strong plant architecture, healthy root development and dense, vibrant foliage. By supplying a balanced spectrum of NPK, CaMg and trace elements, Full Spec A/B helps build the foundation for heavy yields, high potency and strong aromatic expression.
Full Spec A/B is designed to encourage true phenotypic expression, allowing cultivars to perform at their full potential through both growth and flowering stages. Its refined mineral chelation and balanced ratios support efficient absorption, improved photosynthesis and consistent crop performance across the entire cycle.
Suitable for rockwool, coco coir, soil and hydroponic substrate systems, Full Spec A/B can be used in indoor, greenhouse and outdoor cultivation environments. Clean, concentrated and cost-effective, it delivers a low cost per litre of fertigation solution while maintaining the consistency and reliability required by both boutique gardens and commercial cultivation facilities.
Backed by horticultural science and developed through years of practical crop refinement, Full Spec A/B gives growers access to proven, commercial-quality nutrition designed for safe, repeatable results, strong growth, heavy flowering and premium crop quality from start to finish.
