First testing phase with new lights began on 6/3/2015. Various plugs plants have been purchased and potted-up to test the growth rates over a 7 to 10 day period. A selection of Geraniums, Petunias and Coleus have been chosen as demonstration plants. The plants will receive a programmed 20 hours of light per day.
The light itself consists of a panel with a full spectrum mixture of 48 Luxeon Rebel LEDs consuming around 150 watts of power. This panel is cooled by passive conduction and passive convection.
For the next testing phase the LEDs will be doubled to 96 with the panel then consuming around 300 watts of power. This panel will be cooled by a mixture of passive conduction and forced convection with two 12v fans operating continuously.
Continuation of first testing phase – 18/4/15, now with 96 LEDs.
