With the Kosmos Hydro Garden experiment kit, children grow plants completely without soil. The clever funnel system makes watering easy directly into the water reservoir. Through the transparent housing of the station, the growing roots of salad and herb plants can be closely observed. Equipped with useful accessories such as a magnifying glass and pipettes, this STEM set playfully teaches the biological basics of hydroponics. The hydroponic system offers a clean method to explore plant growth right in your own room from sowing to harvest.
