Description
Biobizz Bio Grow is an all organic growth promoter made from 100% Dutch sugar beet extract. This potent growth formula is a complete fertiliser solution containing everything your plants need. Enriched with 70 trace elements, natural sugars, humic acids, kelp, and vitamins B1, B2, C and E; Bio Grow is one of the best organic growth promoters out there.
Biobizz Bio Grow has an NPK ratio of 4-3-6 and is a well-balanced fertiliser. Designed for use with mostly all types of soil, Bio Grow primarily works by activating bacteria in the soil which in turn helps boost the vegetative growth of your plants.
With a high concentration of nitrogen, Bio Grow is most suitable for use during the vegetative stage of development and is perfect for continued use on herbs and leafy greens. However, it can be administered throughout the entire growth period on all plants and is used by many growers as a plant tonic during the flowering and fruiting stages.
Key features of Bio Grow include:
- High nitrogen concentration for vigorous vegetative growth
- An abundance of trace elements, sugars, vitamins and humic acids for healthy plants
- All-organic complete fertiliser solution made entirely from sugar beet extract
- Ideal for organic gardeners and those growing in soil
Biobizz is a Dutch-based company and they have been making great organic fertilisers for over two decades. As one of the most trusted manufacturers of organic fertilisers, Biobizz products (including Bio-Grow) are ideal for those who like to grow the natural way in soil.

How to use
Add Bio Grow to the water at the dose for the week. In Light Mix or Coco Mix, Biobizz's schedule starts at 2 ml per litre, rises to 4 ml per litre in early flowering and falls back to 1 ml per litre by the end. In All Mix, which is pre-fertilised, it stays at about 2 ml per litre.
Bio Grow and Fish Mix do the same job: use one or the other, not both. The full schedule is in the Biobizz feed chart.
Questions
Can I use Bio Grow during flowering?
Yes. It is richest in nitrogen, so it suits the vegetative stage best, but it can be used through the whole life of the plant. Biobizz's own schedule keeps it going through flowering alongside Bio Bloom.
Should I use Bio Grow or Fish Mix?
One or the other, not both: they do the same job. Biobizz suggest switching to Bio Grow for flowering if you have used Fish Mix during growth.
