PRE·MIX is a well-guarded secret. This European fertilizing compost is exclusive to Biobizz. It is used in combination with high-quality organic worm castings to fortify any soil or soilless mix. Pre·Mix™ combines the qualities of many different organic fertilizers, rock meals, trace elements, and fungi in such quantities that optimum growth, flowering, and maximum resistance to disease and fungus are guaranteed. It is used as a transplant or starter fertilizer to give added nutritional value and microbial life to your soil or planting mix. Blend into soil or soilless substrate when planting or transplanting. Pre·Mix™ can be used to make your own soil mixtures (3-5% dose of the total soil planted) or added directly to the soil as a standard basic fertilizer.
