LightScout Red/Far Red Meter
[SP03412]

Plants use the Red/Far Red light ratio to determine how crowded they are, and grow tall or full accordingly. Previously, Red/Far Red measurement required expensive spectroradiometers or sensors, and post-measurement computation. The Field Scout meter displays the Red/Far Red ratio on the LCD screen, and with the push of a button, the 660nm and 730nm readings.
