Soil – Bionova-nutrients

Soil cultivation is the classic and most accessible growing method, allowing even novice growers to achieve impressive results. Using soil as a growing medium provides a natural environment for roots to develop, supports healthy microbial activity, and ensures steady nutrient absorption for strong plant growth. Whether you are cultivating vegetables, herbs, or ornamental plants, soil offers a reliable and forgiving option for growers of all experience levels.

Growing in soil is the most natural cultivation method, but top yields demand more than good earth. You need plant nutrition specifically formulated for the buffering character of soil substrates. Bionova's Soil Supermix was the world's first single-component main fertilizer, launched in 1993 and still one of the most trusted liquid soil fertilizers in professional horticulture today.

All-in-one NPK fertilizer for soil from seedling to harvest

Soil Supermix (NPK 7-3-6) covers the full vegetative and bloom cycle in a single bottle. Its unique blend of chelated trace elements and food-grade minerals is directly absorbed by the plant, giving you precise control from week one until a week before harvest. At a 1:400 concentration ratio it's also one of the most cost-effective plant nutrients on the market, available from 250 ml up to 1000 litres.

For maximum flowering performance, always combine Soil Supermix with PK 13-14 as a bloom booster throughout the flowering period. Pair it with Bionova stimulators like X-cel and The Missing Link to push yield, dry weight, and terpene profiles even further.
