Premium Aroid Substrate Mix

The balanced 'Premium Aroid Substrate Mix' for plants is generally perfect for all types of indoor and greenhouse plants. The components are listed by proportion as follows and will be further explained below:

Pine bark, coco chips, premium sphagnum moss, perlite, pumice, lava granules, coco humus, pre-fertilized charcoal.

The normal variant contains pumice and lava granules in a grain size of 3-8mm, the coarse variant in a grain size of 8-16mm.

Characteristics of the components:

Generally, coarse components loosen the substrate, and the various components also provide properties such as temporary water and nutrient storage and slow release thereof, as well as antibacterial properties.

Pine bark: Its coarse and dimensionally stable structure improves air circulation in the medium, allowing more air to reach the plant roots --> reducing root rot. It also absorbs moisture, releases it slowly, and extracts some nitrogen from the soil.

Coco chips: As a coarse structure, it essentially has the same properties as pine bark, but it is softer and more absorbent. This facilitates root formation and improves water retention.

Perlite: This is a volcanic rock structure with a very large surface area and a neutral pH value. The large surface area serves for water storage and improved aeration of the substrate. Due to these properties, perlite is very often used for soil improvement, also in garden/lawn areas.

Pumice: Pumice has similar properties to perlite, but is more dimensionally stable and therefore more durable. It improves drainage, air circulation, and water retention capacity, and can also indirectly promote root growth and nutrient supply.

Lava granules: Lava granules are also a porous, volcanic rock structure with similar properties to pumice and perlite. The weight of volcanic granules is higher than that of pumice, which can also weigh down plant pots.

Coco coir: Consisting of the fibers of the coconut palm and the outer coconut shell, this soil offers good water retention capacity and little resistance to root growth. Coco coir is generally very low in nutrients, but can absorb calcium and magnesium and release potassium and nitrogen as needed.

Sphagnum moss: Has an outstanding water retention capacity and loose structure, which is why it is very often used for rooting cuttings or air layering future cuttings. The loose structure increases air circulation, and its water absorption capacity absorbs excess water in the substrate.

Pre-fertilized charcoal: A true all-rounder! Lowers the pH value, absorbs excess water, has antibacterial properties, prevents mold, and acts as a slow-release fertilizer (when pre-fertilized).
