Per-urban land or rooftop space can be hired, for example, rather than owned. However, a clinching point about Des Boxsell's system is his information service to customers, before, during and after a sale. He's always available to customers for a helpful chat about any problems. He also provides wise words about good marketing of the hydroponic produce. Such service is rarely available from competitors because most of their sales staff have not had the practical growing experience.
Des is always ready to experiment, and to apply lateral thinking to a grower's problem.
Two growers are changing from rectangular or round cross sectionn channels to the oval system, and one started with the oval system annd is about to undergo a threefold expansion of it. The first grower is Rudi Heesman at Mt Nathan. To lower operating costs. To improve cleaning. He has 28,000 channel holes in which to plant 10 crops of lettuce a year.
