Very special composition color blind test used in substrates for growing plants, perlite and vermiculite are both important components color blind test in the indoor cultivation, each performing its function on the substrate. With his appearance styrofoam, perlite is a mineral presented commercially as tiny white spheres and rounded. Just as vermiculite, is a non-organic additive used to aerate and help maintain the moisture of the substrate / soil, both in indoor growing as well as in beds and pots outdoors. Many confuse them, although the vermiculite has higher water retentivity but has a smaller power offsetting aeration therefore these two components are not always interchangeable.
A rock perlite color blind test is more specifically a mineral from the silica group. To get the look of small Styrofoam beads, perlite undergoes a thermal process and what was initially a material of high hardness becomes color blind test a kind of cork ball, but actually it is a mineral compound and inorganic .
Initially color blind test its use was intended for construction, for the composition of light mortar, but was soon discovered by gardening, especially for its versatility, being a totally inert and free stuff so any contamination, fungi, insects or other seeds that could harm the crops. Perlite is inert, lightweight, does not absorb too much water and remains unchanged over time.
Perlite comes from volcanic minerals heated to temperatures around 800-900 C degrees. High temperatures cause the particles to expand up to 13 times its original size, resulting in an extremely lightweight material with the appearance of popped popcorn or Styrofoam. The final product of this process color blind test weighs only 6-10 kg per cubic meter. The super-heated perlite is made up of tiny air compartments, it is possible to observe its high porosity increase in the microscope, with its appearance of cluster of cells. These pores are responsible for optimum aeration of the soil which gives perlite, facilitating the growth of the roots.
The roots need to breathe and this is impossible in a compacted soil, so that the mixture of perlite provides aeration necessary due to the high porosity of this material. While the vermiculite has a high capacity to retain water and will releasing this moisture as the substrate is dry, perlite only retains water on its surface and does not affect the maintenance of moisture, contributing further to the roots have necessary supply color blind test water and oxygen.
In addition to the benefits color blind test already color blind test mentioned, perlite contributes further improving the irradiation of light for the plants. Because of its bright white color, it has the ability to reflect light, and an extra component irradiation mainly to the nearest ground sheets, where lighting is usually impaired. During periods of intense heat, a layer of perlite at the surface of the substrate also prevents overheating thereof, helps control water evaporation. In addition, the effect of reflection of light also repels certain insects and mites, contributing to plant defense. The surface layer of the soil perlite color blind test can also prevent the growth of weeds.
Although both the perlite and vermiculite help retain water, perlite are more porous and tends to allow water to drain more easily in comparison with the use of vermiculite. Thus, the perlite is more suitable for use with land plants that do not need moisture, such as cactus, or demanding of well-drained soil plant environment.
Perlite is used in mixtures of soil / substrate to improve aeration, avoid compaction and modify the structure of the soil, keeping it loose and well drained. Using a standard mixture of 25 to 30% pearlite, associated with a piece of land and another part peat is ideal for most of the crop plants color blind test in general, promote a good oxygenation of the root zone.
Some growers use pure perlite media, which are called totally inert substrates. In this case, regulation of pH and electrical conductivity should be measured with extreme precision, and this technique should only be used by experienced gardeners, since all necessary color blind test for the proper development of plant nutrients need to be added to the medium.
Perlite is also a good medium for rooting and the production of clones, because it promotes and facilitates the formation of roots in a much more effective compared to other substrates containing ground or earth.
Expanded perlite is a natural mineral without chemical treatment or additives. During processing does not generate waste and there is the incorporation of undesirable elements. Once used, the perlite is tota
