When to water the plant? Build a drought alarm!

For some people the plants always look fresh, but for others it just doesn’t work. Too hot or too cold, too much or too little light… And when should you water your plant? Some plants are just very picky. The most important thing is to give the right amount of water. An automatic reminder can make the difference between fresh green and falling leaves. Therefore a challenging project for all hobbyists who don’t feel like a bare houseplant!
