What is BioBizz Bio-Grow used for?
BioBizz Bio-Grow is an organic liquid growth fertiliser designed to support healthy foliage, vigorous plant development and biologically active growing media. Its base is organic sugar beet extract, known as vinasse, which supplies nutrients and naturally occurring sugars. Unlike a veg-only fertiliser, Bio-Grow can continue through flowering to provide background nutrition while bloom-specific products handle the increased demands of flower and fruit production.
Is BioBizz Bio-Grow organic, and what is it made from?
Yes. BioBizz Bio-Grow is an organic fertiliser based on 100% organic Dutch sugar beet extract, commonly called vinasse. This nutrient-rich material comes from the sugar fermentation process and contains naturally occurring sugars that support both plants and microorganisms in the growing medium. Bio-Grow is designed as an organic alternative to conventional mineral-salt growth fertilisers and fits naturally into biologically active and organic-style feeding programs.
When should I start using BioBizz Bio-Grow?
Start Bio-Grow once young plants are established, typically after they have developed around 2–4 proper leaves or reached approximately 10–15 cm tall. Newly germinated seedlings generally do not need immediate feeding because their nutrient requirements are low. Begin conservatively rather than using the maximum dose, particularly when plants are growing in fresh or nutrient-rich soil that already contains enough fertiliser for early development.
How much BioBizz Bio-Grow should I use per litre?
The general BioBizz Bio-Grow dosage is approximately 1–4 mL per litre of water, depending on plant stage, substrate and overall feeding program. Around 1 mL/L is a sensible starting point for young plants or nutrient-rich soil, while higher rates appear later in the BioBizz feeding schedule as demand increases. Avoid jumping directly to the maximum dose; increase gradually while monitoring plant response.
Can BioBizz Bio-Grow be used during flowering?
Yes. Despite its name, Bio-Grow is not restricted to vegetative growth. BioBizz's feeding program continues Bio-Grow during flowering because plants still require nitrogen and general background nutrition to maintain healthy leaves and normal metabolism. During bloom, Bio-Grow is commonly paired with Bio-Bloom and optional flowering additives such as Top-Max. Follow the relevant feeding schedule through flowering and stop during the final water-only period.
Do I need to use BioBizz Bio-Grow at every watering?
Not necessarily. Bio-Grow can be included in regular feeding according to the BioBizz schedule, but frequency should reflect your substrate, plant demand and watering routine. Plants growing in rich soil such as heavily fertilised mixes may require less additional nutrition than plants in lighter or more inert media. The safest approach is to follow the appropriate feeding chart while adjusting for how your plants actually respond.
Can I use BioBizz Bio-Grow in soil, coco and hydroponics?
Yes. Bio-Grow can be used across soil, peat-based and peat-free mixes, coco and hydro-style growing methods. It is particularly well suited to organic and biologically active substrates because its natural sugars support microbial activity. Coco and hydroponic systems require closer attention to pH, calcium and magnesium availability, reservoir oxygenation and system cleanliness because organic liquids behave differently from clean mineral-salt nutrients.
Can BioBizz Bio-Grow be mixed with Bio-Bloom and other nutrients?
Yes. Bio-Grow is designed to work alongside products such as Bio-Bloom, Top-Max, Alg-A-Mic, Bio-Heaven, Root-Juice and Calmag where appropriate. It can also fit into feeding programs using compatible products from other brands. Add each product separately to the water and mix thoroughly between additions rather than combining concentrated nutrients directly. Always consider the total feeding strength instead of automatically running every additive at maximum dosage.
What is the difference between BioBizz Bio-Grow and Fish-Mix?
Bio-Grow is based on organic sugar beet vinasse, while Fish-Mix uses fish-derived organic ingredients. Both can support vegetative growth, but BioBizz commonly positions Fish-Mix as an alternative to Bio-Grow during the vegetative stage rather than something that must be heavily stacked with it. If Fish-Mix is used during veg, BioBizz recommends switching back to Bio-Grow when flowering begins so it can continue alongside the bloom feeding program.
Does BioBizz Bio-Grow help beneficial microbes and soil biology?
Yes. Supporting biological activity in the growing medium is an important part of Bio-Grow's formulation. The natural sugars from its sugar beet vinasse provide a food source for beneficial microorganisms, helping maintain an active root-zone ecosystem. Bio-Grow can therefore work well in living soil and other biologically active substrates. It supports existing microbial populations, however, and does not replace a microbial inoculant designed to introduce specific beneficial organisms.
What pH should I use with BioBizz Bio-Grow?
BioBizz's substrate guidance is generally around pH 6.2–6.5, with tighter control around 6.2–6.3 where precise pH management is required. Biologically active soil can buffer some variation, while coco and hydro-style systems usually benefit from closer monitoring. Add Bio-Grow and your other nutrients to the water first, mix thoroughly, then measure and adjust the final solution rather than adjusting the water before adding nutrients.
Can BioBizz Bio-Grow cause nutrient burn or help yellow leaves?
Bio-Grow may help yellowing caused by genuine underfeeding or nitrogen deficiency, but yellow leaves can also result from pH problems, overwatering, root damage, pests or other deficiencies. Adding more fertiliser without diagnosing the cause can make matters worse. Bio-Grow can also cause overfeeding if applied excessively, despite being organic. If you have fed too heavily, reduce or pause feeding and allow the root zone to return to a healthier balance.
Do I need Calmag when using BioBizz Bio-Grow?
Not in every situation. Bio-Grow should not be treated as a dedicated calcium and magnesium supplement. BioBizz particularly recommends considering Calmag when using reverse-osmosis or very soft water, where calcium and magnesium levels may be low. Hard tap water may already contain substantial minerals, so supplementation should reflect your source water, growing medium and plant response rather than being added automatically to every feeding program.
Can BioBizz Bio-Grow be used in reservoirs and automatic irrigation systems?
Yes, but organic nutrients require good system maintenance. Bio-Grow can create more biological activity and residue than clean mineral salts, so reservoirs should remain well circulated and aerated, while filters, drippers and irrigation lines should be checked and cleaned regularly. Freshly mixed organic feed is generally preferable to leaving nutrient solution sitting warm for several days, particularly in recirculating or fine-dripper systems where residue can become problematic.
How should I store and handle BioBizz Bio-Grow?
Keep Bio-Grow tightly sealed in a cool, dark place away from direct sunlight, excessive heat and freezing temperatures. Normal cool storage is generally sufficient, so refrigeration is not usually necessary. Some settling or separation can occur with organic liquid fertilisers, so shake the bottle thoroughly before measuring each dose. Its naturally fermented smell is also normal and does not by itself mean that the product has spoiled.
