Apparatus and method for use in determining conditions related to a plant

A method for determining conditions related to a plant comprising the steps of:

• placing adjacent said plant one of first and second sensing means, said first and second sensing means when placed adjacent said plant generating respective first and second electrical signals corresponding to first and second conditions related to said plant;
• selectively connecting said first and second sensing means to a common galvanic meter of an indication means for converting said first signal to an indication of said first condition when said first sensing means is connected to said galvanic meter and for converting said second signal to an indication of said second condition when said second sensing means is connected to said galvanic meter;
• and comparing said indication to a first reference corresponding to a preselected reference for said first condition when said indication is generated by converting said first signal and to a second reference corresponding to a preselected reference for said second condition when said indication is generated by converting said second signal.

A method in accordance with claim 17 in which:

• said first condition is the level of light in the vicinity of said plant;
• and
• said second condition is the amount of water in the soil of said plant.
