Innovative grow medium protector

DRIPCAP™ is a patented water conservation tool and grow medium protector that eliminates algae growth and improves even water distribution. It uses a new, innovative dripping method, and hose-holding technology. The DripCap is made from recycled plastic, recyclable and re-usable. Supported by a rear hinge the DripCap splits apart down the centre, enabling an easy, secure installation and removal, at any stage of the plants development.

The two permanently attached hose holders on the top of the DripCap are a ‘friction fit’ method of attachment. Using a gently sloped angle on the inside of the hose-holding cylinders enabled the manufacturer to obtain a snug compression fit on the outside of the hose, creating a firm tight seal without leakage. Making the hose attachment this way allows for a multitude of different size hoses to be accommodated, ranging from 4mm (0.157″) to 7.6mm (0.298″).

You can attach one propagation hose or two. With two propagation hoses attached there are four dripping holes underneath the cap for even dripping onto the medium. The dripper holes are the diameter of 2mm each, larger than the diameter of a common commercially used drip emitter, under normal conditions the holes will not clog.

Drip feeding with a conventional drip stake allows for a host of problems to develop, accompanied by unnecessary and avoidable costs. DripCap corrects these problems and saves money and resources.

Using the old-style drip stake allows water and nutrients to unnecessarily evaporate into the air due to this uncovered method of drip feeding. DripCap covers the growing medium surface from an elevated position. Air vents are incorporated into the sides of the cap allowing for the correct amount of air exchange as well as slowing the evaporation rate of your water and nutrients, saving money and resources.

Conventional drip stakes emit water and nutrients only at one location on the growing medium, it is necessary to relocate the drip stake at some point during the harvest, using employees. DripCap has an even distribution of water and nutrients, completely covering the growing medium surface, efficiently and entirely, never having to relocate the DripCap, saving on labour and costs.

Drip stakes allow algae to easily form on the uncovered moist surface. In most cases labour is required to remove or scrape the algae, weeds and grasses from growing. The DripCap covers the surface, blocking light and minimising algae, saving money and labour from the non-application of anti-algae products.

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.
