The Ultimate Guide to choose the Best Plant Substrates


If you want to grow indoor plants, there are several different types of substrates. Substrates come in different shapes, sizes and colors, so you may need more than one type. Here’s what you need to know about substrates:

Substrates for indoor plants

Potting soil. This is the most common buy plant substrates UK plant substrate in home gardens, but it’s not necessarily the best choice for your indoor plants. The texture of potting soil can be too coarse or loamy for many tropicals and cacti, which prefer finer soils.

Coconut fiber. If you want to grow a wide variety of plants from subtropical to tropical climates, coco coir is an excellent choice because it’s so easy to work with as well as being nutrient-rich and highly aerated (which helps keep roots healthy). It also provides plenty of drainage holes so that excess water drains away from root zones quickly before evaporating from them into your air space above!

Peat moss: Peat moss is another great option for growing indoor succulents–it retains moisture well without becoming soggy after watering due to its high absorbency capabilities (upwards of 90%!). Plus it looks beautiful on top of other types such as coconut fiber or vermiculite when mixed together in order create something like this…

Substrates for outdoor plants

Pebbles: Pebbles are a good choice for outdoor plants because they can help hold the plant in place and prevent it from falling over. They also provide drainage for the soil around your plant, which will help prevent wet spots or roots that rot.

Perlite: Perlite is another type of substrate that works well for outdoor plants because it doesn’t contain any nutrients and is lightweight compared to other types of substrates like gravel or brick chips (small pieces of clay). It’s great at keeping moisture levels high so you don’t have to water as often!

Gravel: Gravel has many benefits when used as an indoor or outdoor plant substrate as well; however, it does tend to absorb more moisture than other options do–which could lead to an uneven surface or soggy soil underneath your container!

Substrates are materials that are used to improve the soil in which plants grow. They can be organic or inorganic and they can be used to improve drainage, aeration, and moisture retention.

The best substrates have a high content of water-holding particles (e.g., clay or sand) so that it holds moisture well when wet. This allows you to keep your roots from drying out during hot seasons when growing season is over but not yet planted again!


Plants need a lot of different things in their lives. They need soil and water, but they also need nutrients and other things that aren’t found in soil.
