Abstract: The present invention relates to a novel counter system for keeping track of light cycles (i.e., light exposure) for plants and other aged products. The counter system is in the form of a small and compact weatherproof device designed to stake into the ground proximal to a crop such that solar light falls on the solar panel disposed on the top of the device. The device has a counter for incrementing a tally of days and/or hours by one unit upon tracking a light cycle for plants. In one embodiment, when the voltage detected by the counter drops to zero, a tally day is increased and the updated counter is displayed on a display screen of the device. In another embodiment, the device may be controlled remotely by a user. The device can be reset to zero and can also be configured for a specific crop.
