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)

The CO ₂ desktop measuring station helps to monitor all climate parameters in your greenhouse . It is used to measure the CO ₂ concentration, temperature and relative humidity of the air with a visible LED alarm. It is the ideal device for monitoring the air quality in your indoor garden.

• large LCD-display that simultaneously shows: CO ₂ concentration , temperature and relative air humidity , calendar (m/d) and time (clock)
• desk stand, can be mounted on a wall or hung between plants
• stores min/max measurements
• records the measurements taken on an SD card (8GB included)
• 6 emoticons indicating room CO2 levels (350/450/700/1000/2500/5000ppm) for easy CO2-concentration
• automatic calibration function
• red indicator ( Alarm ); green indicator ( Save data )
