Plant Magic are a UK company that have been making nutrients and substrate for many years now, starting from their successes of producing exceptionally high-quality organic soils and nutrients for indoor plants. They have built a solid reputation for producing exceptionally high-quality substrates and nutrients.  Soil Supreme is a combination of premium ingredients to boost your plants growth!


Soil Supreme is a peat based potting soil mix. It contains the usual blend of all-natural ingredients such as black peat, white peat, rich compost and growth stimulants, but it’s key area of difference is with the added phytocell ; this is a 100% biodegradable product that drastically increases the aeration and drainage properties of the potting mix. So you get all the benefits of a peat based potting mix, but the extra aeration of the phytocell increases root development and performance, meaning a stronger, healthier and an all-round more productive plant.

It is lightly pre-fertilised to an EC of around 1.2. This level is ideal for establishing plants in when initially transplanting. Easing plants in with a lightly fertilised substrate is the perfect way to start a plant off, avoiding any potential issues with overfeeding and/or burning leaves. It also gives you the option of adding liquid fertilisers to your irrigation regime earlier, giving you more control over the nutrition your plant receives. Suitable for almost any indoor hydroponic grow room to provide abundance.


Ready straight out of the bag. After transplanting into the soil, there is enough nutrition for growing a healthy plant for up to 2 to 3 weeks using nothing but water! It has been produced to work in perfect harmony with the entire Plant Magic range this makes the perfect formula to establish a young plant into a healthy specimen.

It is an incredibly useful starting point for creating your own unique potting mix. it makes an excellent foundation to add other organic inputs such as Insect frass (Ecothrive’s Charge) or Bat Guano (Plagron) for those of you who like to hand craft your own unique organic potting mixes and tailor your mix to your own plants requirements.

If you take the time to apply a little more effort in preparing the soil, it will make a difference to how well a plant responds after transplanting. Ideally, moisten the media slightly and store in a warm place for around 36 hours before using it. This activates the microbial life in Soil Supreme so they can get to work from the very first moment you plant out into it. Bacteria and fungi are essential in an organic environment, helping with nutrient cycling, promoting healthy root growth, warding off unwelcome pathogens and diseases and helping the plant with drought stress.

After preparation 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. Ensure you have the ideal amount of aeration and drainage throughout the entire pot. Tap and shake the pot while you are filing it to ensure the media settles evenly rather than compacting and forcing it down.


This soil will work in harmony with their full bottled nutrient line, either the old timer organic range, or equally well with their mineral 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 week or two. During this initial period, Grow or Bloom nutrients aren’t necessary but you will still benefit from the addition of a rooting stimulant from the Plant Magic range.

The mix is pre-buffered for pH with a liming agent so no need for any expensive pH 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 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 and correct.

Ensure watering at a slow and steady rate, so that pot is even saturation, and 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 and wait until it feels almost half of that weight until you irrigate again. Long waits between irrigations and the peat may struggle to re-absorb the water, almost becoming water replant. Use a wetting agent in this instance to stop water pooling on the surface.


There are beneficial bacteria present, however you can never have enough of a good thing! Using beneficial bacterial products like Ecothrive’s Biosys, can help boost performance when using Plant Magic Soil Supreme.
