Since everything in my house dies (okay, people and animals will survive) I bought the Click & Grow. The installation is super easy: put a light on it, fill the water bowl, put plants in it and plug it into the socket. Think about when you connect it, so that the light is on at night and off during the day. If you find the light annoying (I don't) then it won't bother you during the day. After a few days the plants started to grow, really great! All you have to do is occasionally replenish the water supply, but that will take about 1.5 liters. In addition, the design looks great with my kitchen, making it a real eye-catcher.
