Description
Biobizz TopMax is an organic flowering stimulator that enhances the development of flower size, weight, and aromatic quality through a complex of natural humic acids, fulvic acids, and sugars derived entirely from organic sources. TopMax is designed to work alongside BioBloom as a bloom booster within Biobizz’s certified organic nutrient system — stimulating the microbial activity and nutrient cycling in the root zone that drives the most intensive phase of flower production, while directly providing the carbon compounds that support the metabolic activity of flowering.
What TopMax Does for Flowering Plants
The humic and fulvic acid content of TopMax plays a dual role in flower enhancement. Humic acids improve the physical structure of the growing medium, opening soil particle aggregates and improving water and nutrient penetration. Fulvic acids are smaller molecules that can cross plant cell membranes, acting as chelating agents that carry mineral nutrients directly into cells and stimulating metabolic processes including photosynthesis efficiency and enzyme activity. The sugar content in TopMax feeds the beneficial microbial populations in the root zone that are responsible for the biological nutrient cycling that characterises healthy organic growing. Active, diverse microbial populations produce a range of plant growth-promoting compounds — hormones, vitamins, and growth factors — that amplify the effectiveness of organic nutrients beyond what the nutrient analysis alone would predict. Biobizz has been developing organic growing products for over twenty-five years. TopMax is one of their longest-standing and most trusted products. At The Horticulture Company we stock the full Biobizz range and TopMax is consistently one of the products our organic growers rate most highly for visible impact on flower quality.
How to Use TopMax
Use TopMax at 1–4ml per litre of water from the start of flowering through to the final week before harvest flush. Combine with BioBloom as your complete organic bloom programme. Always pH-adjust your final solution to 6.0–7.0 for soil growing. TopMax is compatible with all Biobizz products and with other organic nutrient programmes. It is listed for use in certified organic production.
