A. The plant light will start its “day” when you plug it in, so if you plug it in during the afternoon, if will always start its cycle then. If you want the plant light to turn on in the morning, just disconnect the transformer from the wall and plug it in when you want it to turn on for the day.

A. Both have a 1-year warranty by Glentronics, Inc.

A. Check to make sure the transformer is firmly plugged into the wall. It is bulky and in some outlets it won’t make contact with the plug correctly. Try plugging the transformer into an extension cord and see if it helps.

A. The moisture sensor can pick up moisture below the top soil so if you stick the probe deep, there may be moisture below the surface even though the topsoil is dry. If the type of plant you’re using the plant light with needs less moisture then stick the probe deep into the soil but if your plant needs more moisture then stick the probe just below the surface. To check the probe, simply remove it from the soil and see if the “Water Me” light goes on.

A. At this time there is no extender you can purchase from Glentronics, Inc.

A. To get 13 hours of light all the time, simply press the “season” button and hold until the summer light flashes, that will cancel the changing of the seasons and give you a constant 13 hours (summer) of light. In order to cancel this just unplug the light from the wall and start the cycles again.

A. Just call Glentronics, Inc. at 800-991-0466, option 3 and they’ll tell you how to proceed.

A. No, the bulb for the plant light is a 9-watt, 6400-Kelvin bulb that simulates sunlight and has a special base. It’s doubtful you’ll find one that fits in the plant light socket at your local store but it must be a 9-watt bulb.
