    Different types of growing mediums 

    1) Peat Moss

    Peat moss is a dark brown fibrous substance formed by the degradation of sphagnum moss and other organic components over hundreds of years. Peat moss became available to gardeners in the mid-1900s, and it has since changed the way gardeners grow plants. 

    Using peat moss as a soil amendment can improve soil structure and increase the proportion of organic matter in the soil. It has an excellent potential to improve soil aeration. It can also effectively control water and retain nutrients that otherwise leach from the soil.

    Peat moss generates a sterile environment free of weed seeds and pests for the plant, which is why it is one of the main ingredients of Best potting soil for indoor plants. It can even be used as sterile soil on its own.

    2) Vermicompost

    Vermicompost is a natural and organic fertilizer produced by the natural breakdown of food in the digestive system of earthworms. Because of the organic substance in this fertilizer, the plant’s growth period can be accelerated. 

    This organic fertilizer has more nutrients than regular organic fertilizers. One of the most significant advantages of vermicompost is that it is reasonably clean and free of common soil contaminants. This advantage makes vermicompost  a good candidate for indoor gardening. Vermicompost has high water and nutrient holding capacity.

    3) Cocopeat

    Cocopeat is a growing medium made from the fibers surrounding the coconut fruit or the fibers of coconut trees. Compared to other forms of growing medium, cocopeat has a higher water retention potential, which aids plant germination. It functions like a sponge and can hold water up to 20 times its weight.

    4) Perlite

    Perlite is an amorphous volcanic glass with a high water content that is often created when obsidian is hydrated. Perlite’s porosity enhances aeration by facilitating air exchange in the soil for plant roots. When combined with other soil ingredients, perlite can increase soil water retention and deliver water to the roots with a uniform distribution throughout the soil for extended periods. Perlite also reduces the leaching of soil nutrients. Due to these numerous benefits, perlite is one of the main ingredients of the best potting soil for indoor plants.

    5) Leaf mold

    Allowing leaves to decay over time leads to leaf mold. Leaf mold is dark brown to black, which reminds us of compost. Leaf mold is nothing more than decomposed leaves. Leaf mold has little nutritional value for flowers and plants and is primarily employed since it increases water-holding capacity, improves soil structure (and hence water and airflow within the soil), and provides habitat for microorganisms. Leaf mold is One of the most frequent growing mediums for houseplants. This sort of soil can provide both good drainage and water storage at the same time.

    1) An appropriate vegetable soil mix can be prepared by combining 50 percent peat moss (because of organic matter) with 50 percent leaf mold (due to high drainage).

    2) Another recommended soil mixture for growing vegetables is one part vermicompost, one part sand, and one part leaf mold.

    Best soil mix for succulents and cactus

    Succulents and cactus plants deserve special consideration when it comes to making the best potting soil for indoor plants. Succulents and cactus require well-drained soil to thrive. Ordinary soils absorb a lot of moisture and cause root rot, preventing cactus and succulents from growing. Heavy soils, vermiculite-based combinations, and other growing mediums that increase water retention should also be avoided.

    1) For these types of plants, a soil mix of three parts peat moss (peat moss gradually supplies water to the plant), three parts sand, and two parts perlites can be used (perlite can create high porosity).

    2) A combination of three parts peat moss, two parts coarse sand, and one part perlite or leca is another good soil mixture for cactus and succulents.

    Suitable soil for houseplants should have sufficient pores, good drainage, and a good amount of nutrients. A good soil mix for houseplants can be a mixture of peat moss, vermicompost, leaf mold, and perlite. This mixture absorbs moisture well and keeps the plant firmly in the soil. Also, due to the presence of vermicompost, the plant’s nutrients are provided to a large extent, but to be sure, it is necessary to use 20-20-20 npk fertilizers once a week (one teaspoon dissolved in one or two liters of water).

    The best soil for microgreens and seedlings

    To create the best Soil mix for indoor plant seedlings, we must consider the factors influencing plant germination. To boost a plant’s germination, we must examine the availability of nutrients, soil and water storage capacity, and the lack of pests and diseases to guarantee that the plant is in excellent condition during its early stages of growth.

    1) A mixture of four parts peat moss (high water holding capacity), one part perlite (improvement of aeration system), and one part vermicompost (supply needed organic matter), can be employed in the early stages of seed sowing.

     2) To prepare the soil for seedlings, you can combine three parts cocopeat, one part perlite, and one part vermicompost.

    3) However, experience has shown that using peat moss and perlite in a 3: 1 or 4: 1 peat moss to perlite ratio is the best soil mix for microgreens and seedling.

    1. This is my potting soil choice:
      If available, I use Foxfarm Ocean Forest potting mix and add coco coir, pumice, vermicast, charcoal…
      I will apply more or less pumice depending on the type of plants. I use orchid bark and very little potting mix for aroids. I use coco coir, pumice, and vermicast for begonias.
