Biobizz Original Pre-Mix – 25 Liter Bag

The perfect mix for first time grows and for reusing substrates

What is Pre·Mix?
Want guaranteed optimum growth, flowering, and maximum resistance to disease and fungal problems?

Pre·Mix combines the qualities of different organic fertilizers, rock meals, trace elements, and fungi – all in just the right quantities in one convenient and versatile pack.

How to use it?
You can use Pre·Mix as a transplant or starter fertilizer. Blend it into any soil or soilless substrate, or combine it with high-quality organic worm castings to add microbial life and fortify the nutritional value of your soil or planting mix.


Keep the soil slightly warm at all times – if it’s too cool, the microbial activity slows down, which makes it more difficult for the plants to grow. You also want to allow the soil to dry out between each watering. Because, as the All•Mix® substrate dries out, fresh air gets in, which helps the soil to breathe.
