Rich, pre-fed organic soil that carries plants through weeks unfed

BioBizz All-Mix is a pre-fertilised organic soil widely regarded as one of the best on the market. It's built to emulate rich outdoor soil with a full, active micro-ecosystem, yet carries enough built-in nutrition to sustain lush growth for the first couple of weeks with no extra fertiliser.

Fixing slow early growth without a day-one feed schedule

Young plants and cuttings often stall when moved into a substrate with little available nutrition or biology to support them. All-Mix gives roots an active, nutrient-rich environment straight away, so early growth stays strong before you introduce any additional feed.

Key Benefits

• Pre-fertilised organic soil with a full active micro-ecosystem
• Sustains growth for weeks with no extra fertiliser needed
• Emulates rich outdoor soil conditions indoors
• Strong, healthy early rooting for seedlings and cuttings
• Easily boosted with amendments to push it further

How to Use

• Pot up directly into All-Mix and water as normal
• Hold off feeding for roughly the first two weeks while the built-in nutrition works
• Introduce your feed programme once the plant's demand increases
• Boost the mix with bat guano, Charge or worm castings
