Perfect for both indoor and outdoor use, it integrates seamlessly with BioBizz substrates to unlock soil nutrient potential and maximize plant growth. ## Description Product Description BioBizz Top-Max™is a 100% organic flowering enhancer. Using Top-Max™ can help your garden with three important tasks: Firstly, the nutrients in Top-Max™ can help increase the actual size and weight of clusters of flowers. Secondly, plants grown with Top-Max™have a sweet, smooth taste in the finished products. Thirdly, using Top-Max™can help increase your plants uptake of nutrients. 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. The 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. Directions 1. Shake the bottle well before use. 2. Dilute the recommended dosage in water. 3. Apply the solution to the base of your plants. 4. Follow a regular feeding schedule for best results.
