Denser, More Aromatic Flowers from a Certified Organic Booster
BioBizz Top-Max is a bloom stimulant built around humic and fulvic acids derived from Leonardite, plus micronutrients, at an NPK of 0.1-0.001-0.1. It works on two fronts: encouraging beneficial bacteria to colonise the root zone, and improving how nutrients move through the plant’s inner tissues once they are taken up. For soil growers running an organic programme, it is the piece that turns adequate flowers into heavy, resinous ones.
Key Benefits
- Larger, denser flowers through improved cell division during the bloom phase
- Better nutrient uptake as beneficial microbes colonise the root zone
- Raises Brix levels by encouraging the production of natural sugars
- Stronger aroma and flavour with increased essential oil production
- Certified organic and made to BioBizz’s own quality standards
- Supports plant immunity, helping crops shrug off stress through a long bloom
Small Flowers and Poor Nutrient Uptake in Soil
A soil that has lost its microbial life feeds slowly no matter what the label promises, and the symptoms are familiar – slow growth, weak roots and airy buds that never fill out. Top-Max rebuilds that biology while the humic and fulvic fraction chelates nutrients into forms roots can actually take up, so the feed you are already paying for gets used.
How to Use
- Soil, flowering and fruiting phase: 2-5 ml/L of water, starting light and building through bloom
- Mixing order: base nutrients into the tank first, then Top-Max, then any other supplements and boosters
- Mix thoroughly before checking anything – add to the water container and stir well
- pH: adjust the finished solution once everything is in, not before
- Suitable medium: formulated for plants growing in soil
