A Dutch nursery for Helleborus has a tube/rail system in its greenhouse. This is a somewhat unique combination of greenhouse layout and crop since normally there is no rail/tube system available in a Helleborus nursery. To make good use of this layout, a Micothon spraying cart with tube/rail drive was converted to an extractor with four hoods and extractorfans which can span up to four flowerbeds wide. This solution was unique, but was made possible by the special projects team at Micothon and the customer. Also custom built one-offs are a specialty of Micothon's engineers.
