2. Description A simple and affordable aeroponic plant growth chamber to study the effect of sound on plant healing and growth.

3. Functional Requirements  Light radiation in the Photosynthetically Active Radiation (PAR) spectrum (400 to 700 nm).  Air velocity between 0.3 and 0.7 m/s.  Optimum chamber temperature of 68  F during light hours, and 77  F during dark hours.  Use Hoagland solution Type I.  The pH should be maintained between 5.5-6.5.  Capability to administer sound (noise).  Sound level 90-100 dB.  Frequencies in the 1-16 kHz octave bands.  Capability to control and monitor various environmental parameters from a remote server.

4. Non-functional Requirements  Monitor, measure, and report the following parameters as required by NCERA-101:  Atmospheric moisture inside the chamber (Relative Humidity (RH))  pH and Electrical Conductivity (EC) of the nutrient solution  Substrate (air)  Chamber properties: Specifications (floor area, dimensions) Barrier beneath lamps (whether present and its composition) Air flow (whether up, down or horizontal)  To build a web interface to monitor and control various physical parameters.
