Hydroponic Systems International – Combined System

The Combined System from Hydroponic Systems International is a drainage/collection system for hydroponic systems that use bulk substrate.

The combined system, as the name indicates, groups the Bulk Substrate Gutter System with the Complete Drainage Collection System. The top part of the system contains the Gutter for the bulk substrate where the crop will be cultivated, draining perfectly, and allowing the bottom part to correctly perform its function of collecting the drainage providing aeration to the substrate and allowing a perfect root development.

This can help the grower achieve greater efficiency in drainage management, while allowing better root development and the growth of stronger and more vigorous plants, reducing disease problems.



What sets Hydroponic Systems International systems apart from other available hydroponic drainage/guttering systems, is their unique spacer system.

The Spacer provides a firm support to raise the substrate bags from the ground (or the gutter), allowing the drainage to circulate optimally underneath, avoiding the possibility of contamination in the same growing line. At the same time, the Spacer prevents plant roots from coming out of the substrate bags and coming into contact with the drainage. The Spacer minimizes the accumulation of moisture under the substrate, between the bag and the surface that supports it, and allows efficient drainage.

Due to the above, the Spacer helps to reduce the proliferation of diseases and their contagion between plants. With the use of the Spacer, aeration between the substrate bag and the drain flow is maximized. As a benefit of all this, the Spacer allows the grower to have significant savings in the use of fertilizers, phytosanitary products, and even allows savings in labour (no longer have to cut roots that come out of the bags, nor have to tilt the bags, nor open more drains because they have been covered with the roots that come out of the bag, etc.). The Spacer allows growers to maximize the reuse of drainage water (water + nutrients).

In the end, the Spacer helps to lessen the loss of plants during the production cycle, thereby achieving an important increase in production, both in quantity and quality.
