Data from: ‘GreenLight - An open source model for greenhouses with supplemental lighting: Evaluation of heat requirements under LED and HPS lamps’



This dataset includes measurements collected during a greenhouse trial in 2009-2010 in Bleiswijk, The Netherlands, and results of simulations aimed at reproducing the greenhouse as a mathematical model.

The greenhouse trial was conducted between October 2009 and June 2010 by WUR Greenhouse Horticulture and Flower Bulbs in Bleiswijk, the Netherlands. The experiment compared the growth of cocktail tomatoes (variety Sunstream) in greenhouse compartments with 4 different installations of artificial lighting: (1) full LED toplights, (2) full HPS (high-pressure sodium) toplights, (3) hybrid HPS toplights and LED interlights (lamps between the crop rows), (4) hybrid LED toplights and LED interlights. In all installations, lamps provided in total 170 µmol/m2/s PAR light. In the hybrid installations 50% of the artificial light came from the toplights and 50% from the interlights. This dataset includes only the data used in Katzin et al (2020): outdoor weather, indoor climate, and greenhouse climate control actions, for installations (1) and (2) only (full LED toplights and full HPS toplights), between 19 October 2009 at 15:15 and 8 February 2010 at 15:15.

Model simulations were performed by GreenLight, an open-source greenhouse simulation model. Four simulations were performed: (1) A simulation of the indoor climate with HPS lamps; (2) A simulation of the indoor climate with LED lamps; (3) A simulation of the energy use with HPS lamps ; (4) A simulation of the energy use with LED lamps.
