The positive effect of cooling on production has been more than demonstrated in recent years. Both quantitatively and qualitatively. The possibilities for applying cooling in the greenhouse have increased significantly too in the recent past. Consider here soil, air or water cooling. The Bom Group has in this time realised countless successful projects including for the cultivation of amaryllis, freesias and alstroemerias (soil cooling) and also tomatoes, sweet peppers, cucumbers and phalaenopsis (greenhouse cooling).
