摘要:
A foil growing house for the cultivation of gardening products is equipped with an open- and/or closed-loop device for changing the climate. It is designed as a truncated cone made of foil (4) and has a ventilation flap (3) at the upper end which serves for the temperature and solar intensity control. A support tube (2), or standing tube, is used as a mast filled with water and thus outputs at night heat absorbed during the day. A device is provided for the measurement and regulation of the ground dampness e.g. a high quality steel peg (5). The necessary control energy is supplied in conventional form from a solar module (1).
