Hydroponic Cultivation Trough (20x40x20)cm
Made out of high quality polypropylene, the troughs consist of tall side walls. They have the capability of being filled with any kind of hydroponic growing media like perlite, pumice, coir, peat etc. They may have drain holes at the bottom, on the sides, or no holes at all. Special support kit holds the side wall on place and overcomes media weight and root pressure. A specially shaped trough has recently enriched the range of these products. It has an extra folding near the top of both side walls, that improves rigidity and straightens up the edges of the troughs, giving both structural and visual benefits.
