Greenhouse Perlite

Perlite's chemical structure is persistent. It is a neutral material. It is water resistant, does not melt or participate in chemical reactions. Due to these properties it is used in agriculture for growing a wide variety of plants. It is also free from disease, weeds and insects and has ultra light weight.

Due to its excellent aeration characteristics (perlite’s porosity is about 90% of air's porosity); perlite provides great drainage and soil aeration. Pores in perlite grains increase filtration properties and lessen swelling. Perlite allows economizing water expense by lessening water necessity.

Perlite is inorganic. It is free from disease and rotting. Due to low quantity of active ions it does not participate in reaction with salt or alkali. Perlite is neutral (pH=6,5 - 7,5) and its low chemical reactivity allows to maintain close to environment's pH level.

Its heat insulation characteristics allow lessening of temperature change influence on plants.

Perlite is a durable material. It is sterile and its structure does not change after processing. It can be used in agriculture for about 6 years providing a chance to receive crops earlier by improving productive  environment. Due to its structure it prevents damage of young plants.

Perlite does not swell, make foam, contaminate or crack, it has great drainage characteristics.
 
Almost 95 % of foreign countries use it for soilless agriculture purposes. It is possible to use perlite independently as well as in mixes with sand, peat and wood dust. 
 
Short list of benefits of perlite use in agriculture :

» Perlite increases infiltration and lessens swelling. Provides economic irrigation.
» Due to low quantity of active ions it is free from alkaline and salt  reactions;
» Neutral (pH=6,5-7,5). Easily maintains environment’s pH.
» Insulating. Minimizes negative impact of day temperature change on plants.
» In soilless agriculture. Provides early harvesting. The structure of perlite does not change after sterilization. This allows using it up to 6 years. Recommended replacement   frequency  once in 2 years.
» Due to its inorganic structure the use of perlite in agriculture does not carry any risk of plant disease or weed seeds.
» Perlite’s porous structure provides high water holding capacity and allows regulating humidity for plants by giving out water when necessary. It assures better plant grow.

Maintenance Form

Production in bags: Perlite or perlite containing mix is packed into necessary quantity of bags. Plants are easily grown by planting them directly into these bags. The bags are placed on black plastic film so they would create rows. Additional fertilizing and irrigation are provided by fertilizers solutions.

Soilless production: perlite is placed upon plastic film in a layer of various thicknesses. Young plants are planted on certain distance into this layer. Water and fertilizers necessity is covered with irrigational water.
