G3 LED grow light trial

The cucumber seedlings have developed their first true leaves and the roots are protruding from the cubes so they have been been planted in 4" pots.

The seedlings will be grown in these pots, in the tent, using a new 90 watt G3 LED until they are large enough to be finally transplanted into an Autopot system.

The temperature, at the time the photo was taken, was 74 degrees, the RH was 73 and the light level is in excess of 2,000 footcandles with the light 12" above the plant surfaces. I will be using a 14 hour lighting cycle throughout this trial.
