Improving the drainage of container-grown blueberry crops can improve both fruit quality and yield according to the manufacturers of a new hydroponic tool.
The Spacer Hydropot system from Spanish company Hydroponic Systems improves root development, and therefore overall plant growth. It consists of a polypropylene gutter which raises the growing bag off the ground, and a 30×30 cm ‘tray’ which supports the bag. The system ensures air movement and drainage below the roots, while keeping them contained in the growing media.
“It allows blueberry growers to obtain all the advantages of our system: the optimum aeration between the substrate and drains, the prevention of root exit from the substrate and its contact with drainage,” explains Maria Gimenez Lopez from Hydroponic Systems. “Thanks to the easy installation and disinfection and the efficient drainage circulation, the diseases decrease – offering eventually a production that’s both higher in quality and quantity.
“This system evolved from systems having the pot resting directly on the ground to using different supports (such as polystyrene or bricks) up until the current Spacer Hydropot. Bricks or polystyrene do not allow aeration between the substrate and the drains and as a consequence the roots leave the substrate.”
