BioBizz Light Mix is ideal for establishing plants, seedlings or cuttings - formulated to encourage rapid rooting & healthy growth thanks to its blend of beneficial bacteria & organic fertilisers. The highly active micro-organisms get to work in the soil & provide an organic catalyst to encourage a faster uptake of nutrients, & therefore a healthier plant!

Comprised of super high-quality peat, ideal nutrient levels, bacteria to improve nutrient uptake & added perlite to improve aeration & drainage. With countless years experience in developing & producing organic products, you can rely on BioBizz!


The Light Mix soil is an organic peat-based potting soil mix. It is an all-natural blend of ingredients such as black peat, white peat, compost, worm cast & perlite. It is pre-fertilised, but to an EC of around 1.2, roughly half the rate of the All Mix. The Light contains a blend of organic fertilisers, compost, beneficial bacteria as well as perlite to help aid with drainage & aeration. The nutrients, beneficial bacteria & physical properties are designed to emulate a rich outdoor soil. Certified as organic by the control union, you can be confident it will produce you some of the finest plants possible!

Suitable for most indoor hydroponic grow rooms, BioBizz Light Mix is perfectly suitable to help grow exceptional organic flowers.


It can be straight from the bag alongside the BioBizz fertilisers. Alternatively, it can be used as a starting point for those who like to tinker around with organic amendments. As it is lightly pre-fertilised, it makes an excellent foundation to add other organic inputs such as Insect frass (Ecothrive’s Charge) or Bat Guano (Plagron) to create your own unique organic potting mixes to your own requirements.

If you take the time to apply a little more effort in preparing the soil, it will make significant differences to how well a plant responds after transplanting. Ideally, moisten the media slightly & store in a warm place for around 36hrs before using it.

Essentially, this makes sure that the microbial life in the soil is active from the very first moment you plant 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 ensure you break it up as much as possible. When filling the empty pots, do not compact the soil down while transplanting. You want to make sure you have the ideal amount of aeration & drainage around the plants roots. Tap & shake the container while you are filing it to ensure the media settles evenly rather than forcing it down (compacting).


Light Mix has been designed to work in harmony with their full bottled nutrient line. It does not contain a lot of nutrient (EC 1.2) so (depending on plant type) you will need to begin to use a fertiliser after the first or second watering. During this initial period, Grow or Bloom nutrients aren’t necessary but you will still benefit from the addition of a rooting stimulant such as BioBizz Root Juice, before you start to add fertiliser.

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 the roots are evenly saturated, & the solution doesn’t just take the path of least resistance out the bottom of the soil. Weigh it after you have irrigated & wait until it feels almost half of that weight until you irrigate again. If you leave it too long between irrigations, the peat may struggle to re-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 beneficial bacterial products like Ecothrive’s Biosys, can help boost performance also.

Do not plant out too big! The soil could stay wet too long for a small root system, make sure you go up in potting size at the appropriate rate.

For best results, follow the BioBizz grow guide, but remember it is a ‘guide’, so adjust based on your own observations too.
