Biobizz All Mix. It Does It All. 

If you’ve ever found yourself staring at a bag of standard compost from the garden centre and thinking, “Is this it?”, then prepare yourself. Because Biobizz All-Mix isn’t just a bag of dirt — it’s a living, breathing ecosystem, lovingly pre-packed and ready to turn your growing ambitions into glorious, leafy reality.

Simply put, Biobizz All-Mix does exactly what it says on the bag. It does it all.

It's In The Details. 

Imagine taking the finest outdoor soil, cramming it full of beneficial microbes, turbo-charging it with rich organic matter, and then preloading it with enough nutrients to keep your plants in clover for weeks. That’s Biobizz All-Mix.

This isn’t your average backyard mud pie. Biobizz All-Mix is a heavily pre-fertilised substrate designed to create the perfect environment for plants to absolutely flourish all year round. Think of it as nature’s version of a five-star hotel for roots: everything your plant could possibly need is already in there.

Biobizz All-Mix Is a Game-Changer

The team at Biobizz are the undisputed kings of organic growing, and All-Mix is their crown jewel. It’s a careful, potent blend of soil, compost, worm castings, and perlite — but the real magic is the Biobizz Pre-Mix, a biologically active cocktail of organic goodness that kicks off the microbial party as soon as you open the bag.

The beauty of Biobizz All-Mix is that it’s powerful enough to sustain lush plant growth for a couple of weeks without needing any extra fertiliser. Perfect if you like your plants big and healthy but don’t fancy hovering over them with a bottle of nutrients every five minutes.

The Secret Behind the Biobizz Science.

Unlike synthetic fertilisers, which can leave your soil more toxic than a reality TV reunion show, Biobizz All-Mix contains only natural and organic elements. There’s no magnesium sulfate nonsense here — just clean, sustainable inputs.

This purity gives All-Mix a high Electrical Conductivity (EC) value, meaning there’s plenty of natural food available for your plants. Even better, the soil’s self-regulating organic ecosystem helps maintain pH levels at exactly the right range, without any fiddling or chemical tinkering from you.

It’s almost unfair how easy it makes things.

How to Use Biobizz All-Mix

Using Biobizz All-Mix couldn’t be simpler, but there are a couple of tips to make sure you’re getting the absolute best from it.

First, moisten the mix slightly and leave it to stand for 36 hours before you plant anything. This wakes up the army of beneficial microbes and gets the whole biological machine ticking nicely.

Once you’re up and running, keep the soil slightly warm — a chilly grow room will slow down microbial activity, and your plants will sulk accordingly. Also, let the soil dry out between watering sessions. Not bone dry, obviously, but enough to let fresh air reach the roots, keeping them healthy and firing on all cylinders.

And yes, Biobizz All-Mix loves being paired with other Biobizz favourites like Bio-Grow, Bio-Bloom, and Top-Max for even more outrageous plant performance. It's designed to work hand-in-hand with the full Biobizz nutrient line-up, from the vegetative stage right through to flowering.
