In the case of horticultural training, that's a job that can be considered seasonal. But if you calculate the number of hours worked during the year, that corresponds more or less to 35 hours a week over 52 weeks, because there can be quite a lot of hours of work during the production period, which entirely suits the clientele interested in this kind of training because that enables them to have a break between two periods of work. People are also selected on the basis of those criteria. The other two types of training lead to work that is available year-round.
