An automatic computerized timer turns the lamp on and off, simulating the day length in cycle with the four seasons. The soil moisture sensor eliminates the guesswork about watering. To vary the light intensity or accommodate larger plants, the telescoping stem adjusts from 7" to 14" high. The base of the lamp that holds the pot measures 6" x 7". The textured pebbled base serves as both a catch basin and humidity/drip tray. A wonderful gift to keep bonsai thriving whether at home, office or classroom. Instructions included.
