Garden Highpro MEDIPRO is a thermo-hygrometer that shows the distance from the top of  the plants to the lamp, reducing the risk of "light burn" in case they are very close to the bulb. Its modular system allows you to easily maintain the desired distance of plants from the lamp - according to the light they need in the different stages of development. 

• indicates temperature and humidity on the top level of the plants
• easy to adjust
• possibility to change the height from 10cm up to 50cm
• for hanging on a E40 socket
• 1pc  LR44 1. 5V battery (included)
