Balls of expanded clay export between 8 and 16 mm. Expanded clay in hydroponic allowed a very high ventilation of the roots with the retention capacity of the nutrient solution.
Derivative of an abundant and renewable source (clay), export ® It is considered a sustainable ecological substrate. The Clay is in the form of balls and baked in rotary kilns to 500 ° C. This causes the clay to expand, as the popcorn of corn and porous.
LECA export ® is light in weight, is not compacted and is completely reusable - can be cleaned and sterilized after use. Inert is neutral pH and does not contain nutrients. Water drains freely by the Arlit and does not hold water in excess, which offer good level of oxygenation around the roots and is suitable for flood and drain systems. In the Arlit drip irrigation systems can be used, Since it is a substrate to ejerece capillary action, as well the nutrient solution is distributed evenly, preventing the appearance of salts. EXPORT ® is normally used in hidrocultivos / hydroponic systems.
Compared to Earth normal export ® offers many advantages:
-The material is not only completely clean but is also odorless
-It ensures good aeration of the roots
-It prevents excess acidity
-Prevent pests from the Earth
Due to its capillary action has ownership and capacity of store water evenly, accelerating the growth of the plant.
