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.

How to Use

Questions & answers
Do I need to feed straight away in All-Mix?
No. All-Mix is pre-fertilised, so hold off feeding for roughly the first two weeks while the built-in nutrition does its work. Start your feed programme once the plant's demand increases.
Can I add anything to it?
Yes, it takes amendments well. You can boost it with bat guano or worm castings to push it further.
Is it for indoor or outdoor use?
Both. It's made for indoor and outdoor container growing, and is built to copy rich outdoor soil with an active micro-ecosystem.
What bag sizes are there?
20L and 50L.
Can I collect it from the Wembley store?
Yes, you can collect from our Wembley store, 250 Water Road, HA0 1HX, Monday to Saturday. We also deliver bags across the UK, with a delivery charge per bag added at checkout.
