Growing completely hydroponically can offer fantastic rates of growth & yields that are hard to match, however, there are growers who prefer a more traditional option, & laugh in the face of talk of pH or EC meters. High quality potting soils like BioBizz All Mix offer exactly this option! BioBizz’s All Mix potting soil offers indoor gardeners the opportunity to grow some of finest organic produce possible, while keeping the whole process simple throughout.

Comprised of super high quality peat, enough nutrient for up to 4-6 weeks plant growth, beneficial bacteria to improve nutrient uptake & root development & added perlite to improve aeration & drainage, BioBizz cover all bases when it comes to producing a high-grade peat-based potting soil.


The All Mix soil is an organic peat based potting soil mix. It is a blend of all-natural ingredients such as black peat, white peat, compost, worm cast & perlite. It is heavily pre-fertilised with nutrients & contains a blend of beneficial bacteria, designed to emulate a rich outdoor true-living soil. Certified as organic by the control union, you can be confident it will produce you the finest organic plants possible!

Suitable for almost any indoor growing room, BioBizz All Mix is suitable for growing exceptional organic flowers whether you are hand watering or using with a drip-irrigation system.


Most growers simply pour the contents out of the bag into the pot & plant straight out. While of course you can do this, (it is the simplest way to get going!) a little more effort preparing the soil before you plant into it will make a significant difference to how well a plant responds after transplanting. Ideally, moisten the media slightly & store in a warm place for around 36hrs before using it. This will make all the difference in having a super healthy plant.

This makes sure that the microbial life in the BioBizz All Mix soil is active from the very first moment you plant out into it. Beneficial bacteria & fungi are essential in an organic environment, helping with nutrient cycling, promoting healthy root growth, warding off unwelcome pathogens & diseases & helping the plant with drought stress. A potting soil without a fully functioning eco-system is only really half a soil!

Once the soil is prepared, make sure you fluff up any compacted lumps of media in the bag. During the transportation process, it will become compacted slightly, so you need to ensure you break it up as much as possible. When filling the empty pot, do not compact the soil down while transplanting. You want to make sure you have the ideal amount of aeration & drainage throughout the entire pot. Tap & shake the pot while you are filing it to ensure the media settles evenly rather than compacting & forcing it down.


BioBizz All Mix potting soil has been designed to work in harmony with their full bottled nutrient line, though for the first 2-4 weeks there is enough nutrient pre-loaded in the potting mix already. For this period you don’t need to use a main grow or bloom nutrient. You may well benefit from the addition of a rooting stimulant such as BioBizz Root Juice, but do not be tempted to fully fertilise as you may well end up overwhelming your plants!

The potting mix is also conveniently pre-buffered for pH so no need for any expensive meters either! The liming agent that is used in the potting mix automatically corrects any pH variations in the substrate back to the ideal level. If you choose to re-use your media, then it may be beneficial to use some dolomite lime each time you re-use it to ensure the pH buffer is still present & correct.

When watering your plant, try to make sure you do it at a slow & steady rate. This will make sure that pot is evenly saturated throughout, & the solution hasn’t just taken the path of least resistant straight back out the bottom of your pot. Feel the weight of your pot after you have irrigated & wait until it feels almost half of that weight until you irrigate again. If you leave it too long between watering, the peat may struggle to absorb the water, almost becoming water repellent. Use a wetting agent in this instance to stop water pooling on the surface.


Although there are beneficial bacteria present, you can never have enough of a good thing! Using products like Trichoderma fungi, can help boost performance when using BioBizz All Mix soil.

Do not plant out into too big a pot of soil! A large pot will stay wet for too long for a small root system, make sure you go up in pot size at the appropriate rate.

For best results, always follow the BioBizz grow guide, but remember it is a ‘guide’, so remember to use your brain as well.
