Table 3 GDD's calculation methods adopted in the trials. Sensory evaluation The technological and quality characteristics of hops obtained from the cv Cascade and Chinook were investigated through the production of two small experimental batches of beer. Table 4 Details of the experimental batches brewed for the sensory evaluation trials.

Statistical analysis All data collected, including yield and biometric measurements, and GDD values obtained by means of all calculation methods, were subjected to variance analysis ANOVA using the Minitab statistical software version Results and discussion 3.

Succulent plants need less water, fertiliser and other chemicals than many commonly cultivated plants. Nijssen's Automation team fine-tunes the control software in close collaboration with the Plant Lighting researchers. For example, the number of adjustable time intervals for Plant Lighting has been increased. The course between the settings is also adjustable: abrupt or gradual transitions.

That is very important when simulating the climate in greenhouses. After all, in greenhouses there is no abrupt transition in light and temperature. Nijssen's control software now gives us the opportunity to simulate the climate in a greenhouse even more accurately in a fully conditioned room. With this range of options, we regard the climate chamber as an optimal research facility. We expect that more and more research will take place in climate chambers in the near future.

Plant Lighting is a private research institute, specialized in the effects of climate on plant growth and development. The company translates scientific plant physiological knowledge into practice and thus contributes to the innovative power of greenhouse horticulture and breeding.
