The material of our containers is thermal insulation, allowing a passive temperature regulation, as shown by the following chart,es: The passive temperature control is crucial for the root. If it is too high excessive root activity consumes too much energy by burning carbohydrates breathing, thereby detracts from the aerial part photoassimilates. In this case end, the roots may die. The substrates involved in a simple plastic film have little thermal inertia, lacking insulation, and its temperature is, with a small differential, Environmental temperatures around them. If however the substrate is isolated by a suitable container, its thermal inertia is much higher and temperature variations (day Night) decrease in the substrate, presenting a soil-like behavior in this regard. Constructed in an insulating material and rigid, airpop, that is also rot and acid resistant solar radiation and so their duration is indefinite. The containers are manufactured in different shapes and dimensions allowing the most appropriate choice, depending on the substrate used (perlite, fibra de coco, rockwool, vermiculite, turbos, etc.) and crop species (tomato, pepper, eggplant, cucumber, cantaloupe, courgette, bean, etc.) or high density cultivation (col china, lettuce, etc.). Also, our containers in continuous channel, They can be used in closed systems drainage recovery, being designed for evacuation the central channel Likewise invertido.De allow an easy and inexpensive heating Root, installing in dual channel background, PP corrugated pipes as round heating and hot water return at low temperature (40-50 º C).
