Arlite or expanded clay is a very light ceramic aggregate manufactured by heating pieces of clay in a rotary kiln at approximately 1200°C. In the lower layer we recommend placing a layer of Arlite, it is an expanded clay that promotes drainage, preventing rotting of the plant due to excess water. When the apices of the roots collide with the Arlite, growth is slowed and the roots bifurcate, making the root network larger throughout the entire substrate , instead of the roots ending up emerging from the bottom of the pot. In addition, it prevents the substrate from being lost through the drainage holes and has a thermal cushioning effect. Prevents rotting of the plant due to excess water. Improves moisture retention. Provides better oxygenation to the roots. inert substrate. Reusable.

Three sizes. Three functions. The volcanic peak. USES OF THE VOLCANIC PICÓN. ⚗️Its physical, chemical and hydrophysical properties will allow this mineral component to be used differently depending on its granulometry (average particle size). 🔹It has a total porosity of 71% and thanks to the internal pores it has an aeration capacity of 48.5%, which is higher than perlite. It does not retain nutrients (very low Cation Exchange Capacity) and has a pH of 7.5 1️⃣Picón fine. With homogeneous grain sizes of 2-4 m. ✔️It is used to make growing substrate mixtures. It should not be mixed with particles of other larger minerals. We know that mixtures with homogeneous sizes work better regarding drainage of water in the substrate. ✔️Can be used as coverage in mini-sized or slow-growing xerophytes: Lithops, Haworthias, etc. 2️⃣ Medium Picón. With granulometry of 5-7 mm. Ideal as a covering aggregate for medium-sized plants. Mainly grown in pots. 3️⃣Thick Picón. With sizes of 8-12 mm. Perfect for large plants and pots and for application as coverage in garden areas. ADVANTAGES of PICÓN AS COVERAGE ✔️In irrigation season, we will have to water less as we lose less water due to surface evaporation ✔️Thermal cushioning of the substrate ✔️Prevents proliferation of weeds ✔️Keeps the necks of plants ventilated: dry necks = healthy necks. ✔️Slow contribution of iron to the soil Ahhh and the rough surface without sharp edges and edges is soft and respectful of the tender tissues of our cacti and succulents. Which one do you use and how do you use it?

Perlite is a material that requires industrial manipulation despite being of volcanic origin. It is the mineral component with the lowest density, which makes it tremendously light . It is the most widely used component to facilitate the aeration of substrate mixtures. There are large deposits of this material in Italy, a nearby country where most of what is used in Spain comes from. Its affordable price, ease of handling and transportation and the fact that it is practically chemically inert and has a neutral pH, would give it preference in mixtures where a high percentage of mineral elements is sought, but without making the final substrate too heavy. Perlite has about 14% closed intraparticle pores, so its total* effective porosity would be 81.4%. As a summary of the perlite: Nº1 IN AERATION. THE GREATEST LIGHTNESS of all mineral ingredients. Lasts 3 - 4 years. It disintegrates into smaller particles over time.
