Perlite is better than vermiculite at improving aeration or air porosity. When either perlite or vermiculite are used exclusively, vermiculite is better for germinating seeds and perlite is better for establishing cuttings. As the sole growing medium in a hydroponic setting, perlite is more suitable, although a mixture of the two is ideal.

Vermiculite is a natural mica mineral that is sterile and helps prevent soil mold and bacteria that rot the roots of your seedlings. It breaks up the soil and retains moisture in the soil.

The Vermiculite Extraction Journey. The vermiculite extraction process is a meticulous journey that begins with mining in the mineral-rich deposits of Makueni County. The raw vermiculite undergoes rigorous screening and separation into fine, medium, and coarse particles, ensuring the highest quality in the final product.

Wet screening and flotation circuits concentrate vermiculite particles from rock/gangue content. The vermiculite concentrate is subsequently dried and screened to produce specified industry standard grades 3, 4 and 5 as designated by grain size distribution. Custom blended ores are available.

 — Vermiculite undergoes significant changes in mineralogical characteristics upon chemical (with H 2 O 2) and thermal (roasting) expansions, resulting in a marked impact on its adsorption behavior toward Pb(II) removal.Both chemical and thermal expansions exfoliated the tightly-stacked bulk structure of raw vermiculite into ultra-thin …

 — Pour vermiculite from the bag into soil. Using 20-25% vermiculite will have a major effect on a soil plot's ability to retain water and promote plant growth. Open up your vermiculite bag and drain the contents into the soil you have prepared for the container. When this is finished, you can add the soil mix to the container.

Vermiculite, on the other hand, is an absorbent mineral that is also used in gardening, as well as insulation and fireproofing. It is made of mica, silica, and alumina, which when heated expand and produce layered, light and absorbent particles. Vermiculite helps increase moisture and nutrient retention in soil, and also has a neutral pH.
