How to Prepare African Violet Soil / Potting Mix ? The soil or potting mix in which an African Violet is planted is very important for the overall survival of the plant. This is because the plant roots.
Expanded Vermiculite Flakes of raw vermiculite concentrate are micaceous in appearance and contain interlayer water in their structure. When the flakes are heated rapidly at a temperature above 870° C, the water flashes into steam, and the flakes expand into accordion like particles. This process is called exfoliation, or expansion, and the resulting lightweight material is chemically inert, fire resistant, and odorless.
It is derived from rocks containing large crystals of the minerals biotite and iron-bearing phlogopit. As these rocks are exposed to the weather, they start to decompose, allowing water to enter and react with the various chemicals present. As the decomposition and chemical reactions proceed, vermiculite is formed. A typical chemical analysis of commercial vermiculite shows it contains 38-46% silicon oxide (SiO2), 16-35% magnesium oxide (MgO), 10-16% aluminum oxide (Al2O3), 8-16% water, plus…
Among the easiest and fastest-growing crops, microgreens offer a palette of fresh flavors, from mild to spicy, and inspire repeated plantings for an ongoing supply of fresh greens for creative uses. Here's how to grow microgreens indoors.
Vermiculite is basically a hydrated phlogopite mica which has the remarkable ability to expand to many times its original volume when heated, a property known as exfoliation. Various chemical formulae are given for vermiculite.
