When the new buildings were being constructed a great deal of attention was paid to fire safety, an aspect that also benefits the employees. According to Danny Geijsman from NU SWIFT fire safety each entrepreneur has to consider three elements– le-

gislation, organisation and insurers. The Dutch Building Decree 2012 is full of important legislation relating to fire safety, but entrepreneurs also have a responsibility in preparing their organisation properly to deal with a calamity that hopefully will never happen. Geijsman also explained when to, and not to, extinguish a fire with CO2, and how Sikes’ farm is divided into fire zones. After this our group took a look at a growing room in the pinhea- ding stage. The beds in the room had just had the pinheads knocked off – which means that a tube or rod knocks away the largest pinheads on the bed to encourage uniformity in the flush – which is abso- lutely essential for farms that harvest mechanically. Rob Arts, who works at the farm, explained: “Our growing schedule usually proceeds as follows. On Mondays four growing rooms are filled and managed according to a four-week cycle. Compost is added at casing by the machine and the beds are prepared – the beds are not ruffled at a later stage. The compost filling weight is about 85-86 kilograms per square metre and is supplied by Walkro Blit- terswijck. Up to cool down we spray approximately 25 litres of water per square metre onto casing soil 75% of which comes from Euroveen and 25% from TopTerra. During pinheading we knock off some pins to encourage uniformity, and in principle we always harvest the 1st flush on Wednesdays. We give the 1st flush some 15 litres of water per square metre, with another 12 litres after the flush. A further 12 litres are sprayed onto the 2nd flush. It takes about two and a half hours to harvest the 1st flush, and ninety minutes for the second one. We mainly harvest in quality classes 2-3-60 and 2-3-80. Total production amounts to 35-37 kg per square metre.”
