Project: SEPT
Date:March 2008

Summary:

SEPT - Super Efficient Photosynthesis. A grow light made from red and blue LEDs being pulsed. This light fits inside a Altoids container and requires less than 1.1W of energy to grow a 6"x6"x6" space. Lights can be chained to grow more plants. Total lumens = 111. Plants need primarily red (680nm) light to grow and a small amount of blue (440nm) light. By pulsing the LEDs at 720Hz or higher the plant can achieve maximum growth with a minimal amount of energy.
