Perlite can be used to grow plants independently; it doesn't need to be mixed with soil or anything else. Perlite is an excellent medium for growing plants without soil because it absorbs and holds water well and makes it easy for oxygen to reach a plant's roots. When perlite is used as a growing medium, it creates a lot of air spaces that let water and oxygen get to the roots of your plants without being blocked. This helps plants grow robust root systems because they don't have to work hard to get the necessary nutrients. The only problem that needs to be fixed is that using perlite as the only growing medium may not be best for all plants. Since perlite tends to float when it gets too much water, it might not be the best choice for plants that need a lot of humidity. If you want to grow these plants, you might first need to mix them with coco coir or peat moss.
