Biobizz Top-Max Flowering Stimulator

Taste, nuance, and aroma taken to the top

There are three excellent reasons to use this 100% organic flowering stimulator. First, it contains ingredients that can help increase the actual size and weight of the flower clusters. Second, nutrient uptake is improved. And third, plants grown with Top-Max result in sweeter, smooth-tasting crops.

How it activates the flow of nutrients is essentially down to how it’s able to free up the minerals calcium, iron, and magnesium, in the soil, which stimulates the plant’s metabolism.

The benefits of humic and fulvic acids in Top-Max

Top-Max is incredibly effective because of the humic acids it contains. The main source of these acids is an ancient substance in the soil called Leonardite. This comes from prehistoric trees and vegetation that flourished during the carboniferous period, 300 million years ago.

Fulvic acids also possess particular properties that contribute to healthy floral growth. These acids are taken from exceptionally rich sources of humate deposits found deep within the earth. Their natural electrical charge attracts nutrients and minerals present in both the microbiological soil base and applied organic fertilizers.

Humic and fulvic acids work together to boost the energy in old plant cells while stimulating new ones to form.

How to use it?

Top-Max can be used throughout the entire flowering period and works especially well combined with Biobizz substrate mixtures.

In the first weeks of flowering, we advise a dose of 1ml per liter of water. As harvest approaches and before flushing, the dose can be increased to 4ml per liter of water. Follow Biobizz’s official Nutrient Schedule for best results.
