New hydroponic medium

Dunlop Foams launched a new hydroponic foam medium named ‘Up&Grow’ at the recent Hydroponic Farmers Federation conference held at Cranbourne, Victoria. Much interest was shown by growers and suppliers of hydroponic systems alike. Two Up&Grow foam grades have been developed by Dunlop Foams and were presented at the conference. The two grades provide for both lower and higher water absorption options.

Up&Grow is made from hydrophilic polyurethane foam developed specifically for the hydroponic industry. It is made in Australia and can be supplied in various shapes or sizes, hence can be tailor-made to suit individual needs. Up&Grow is manufactured to tight tolerances, which provides a highly consistent product.

The foam medium is a clean and green medium. It is a lightweight, highly absorbent material (absorbs up to 30 times its own weight) that has no itchy fibres or dust, and maintains its structure and shape. Due to its high internal surface area, it provides good air-filled porosity combined with excellent drainage. In addition, the foam is inert and sterile and has no effect on the pH or EC of nutrient solutions. Tests have also shown that Up&Grow has no leaching and is suitable for food contact.

One of Up&Grow’s biggest features is its environmental performance. After sterilisation, it can be re-used many times without degradation and can be recycled at the end of its life.

Trials have been undertaken by a number of growers with crops such as lettuce, tomatoes and a variety of herbs. Dunlop Foams is also undertaking further research with Chisholm Institute of TAFE at Cranbourne, Victoria, to provide growers with comparisons of Up&Grow with other media to aid in the smooth introduction of the new medium in established hydroponic systems.
