Bio Fish Mix

R150 - R3 250


This rich infusion of organic fish emulsion from the North Sea, mixed together with extract of Dutch sugar beet helps accelerate the growth of beneficial microbes in the substrate.

Even after a few days of use, it will have transformed poor quality earth into rich, fat soil – full of the natural minerals your plants are hungry for.

Fish Mix adheres to organic farming requirements and therefore is not extracted with acids or stabilized with BHT (butylated hydroxytoluene) – a synthetic preservative.

FAQ - by Biobizz & Green Houston


Is it necessary to use a calcium/magnesium supplement when using the Biobizz products?

Under normal conditions it is not necessary to use a Ca/Mg supplement if we use most or all Biobizz products. Only in some very demanding grows, like some cases of crops in coco coir, would it be necessary to use a Ca/Mg supplement, since it is a demanding and unconventional substrate.


Do I need to use additional bacteria or micorrhyzae with Biobizz?

Not necessarily, but it helps. It is not necessary to inhibit fungi or introduce beneficial fungi into the substrate. Mycorrhizal fungi and bacteria(Explogrow) that we have sourced locally in SA are next to none when it comes to their proven performance and quality in organics. 


Can I use dry amendments (bone meal, kelp meal, malted barely, wromcastings etc) in combination with Biobizz?

Of course! Using organic material in conjunction with Biobizz products is positive, provided that only organic or ecological products are used. However, it is important not to abuse the organic matter so as not to saturate the substrate with nitrogenous bases.


Do you have a Nutrient Schedule for autoflowers?

There is no specific Nutrient Schedule for autoflowering plants, but it is possible to use the current Nutrient Schedule with them. The feeding of the autoflowering is faster, so we should skip some weeks of the regular Nutrient Schedule to adapt to their needs.
