Methods and apparatus for determining when plants require watering, and methods of attending to the watering of plants including signaling the grower that the plants are in need of hydration are provided. The novel methods include real-time measurement of plant metabolics and phytometric physiology changes of intrinsic physical or behavioral traits within the plant such as determining physiological flux measurement of enzyme flux due to environmental changes such as the wind and drought stress, soil and plant mineral deficiencies, or the interaction with a bio-control for organic disease control including, cell movement, signal transduction, internal chemical processes and external environmental processes including when plants require watering, and methods of attending to the watering of plants including signaling the grower that the plants are in need of hydration.

The invention claimed is: 1. A method of detecting plant water deficit stress in plants by measuring plant leaf thickness using a Hall Effect Sensor and using this measurement to determine a level of water deficit in plants, the method comprising: a) mounting a Hall Effect Sensor Integrated Circuit

The invention claimed is: 1. A method of detecting plant water deficit stress in plants by measuring plant leaf thickness using a Hall Effect Sensor and using this measurement to determine a level of water deficit in plants, the method comprising: a) mounting a Hall Effect Sensor Integrated Circuit on the first arm of a gripper like fixture; b) mounting a magnet on the second arm of a gripper like fixer; wherein said mounting permits the arms to touch opposite sides of a leaf to be measured; c) measuring the magnetic flux density; d) converting the measured magnetic flux density into a corresponding voltage; e) comparing the voltage of step d) to voltage measured when no leaf is present; f) determining leaf thickness by comparing the voltages; and g) determining a level of water deficit stress in plants using the determined leaf thickness by comparing the voltages. 2. The method according to claim 1 further comprising communicating said measurement to a user wherein communicating can be selected from the group consisting of: conversion of data into human voice, transmission of data over the Internet to other computers, PDAs or cell phones, transmission of information to pagers, and the transmission of information to cell phones, wherein information is in the form of digital data or human voice. 3. A plant leaf thickness sensor comprising: a) Hall Effect Sensor Integrated Circuit mounted on the first arm of a gripper like fixture; b) at least one magnet mounted on the second arm of a gripper like fixture; wherein said mounting permits the arms to touch opposite sides of a leaf to be measured; c) fixture having a first arm and a second arm for gripping a leaf d) means for measuring the magnetic flux density; e) means for converting the measured magnetic flux density into a corresponding voltage; f) means for comparing the voltage of step e) to voltage measured when no leaf is present and g) determining leaf thickness by comparing the voltages.
