Top·Max™ is designed especially for use in combination with Biobizz substrate mixtures. Sometimes the nutrients in soil are not readily available to plants. The humic acid in Top·Max™ can help change this, increasing the availability of nutrients to your garden.
 

Our humic acid comes from a material called Leonardite, which is ancient vegetation converted into a rich source of humic acid over millions of years. When this ancient plant life died, it was buried deep in the earth and processed by time and pressure into a soft rock like material rich in concentrated humic acid. Humic acid can interact with the nutrients in your growing media, increasing the availability of nutrition.
