Woo! After only a day the one of the sprouts has made a right turn towards the LEDs!!! You can see one sprig is still going towards the window still. It will be interesting to see if it turns as well.

Carrie's drop watering scheme, which is a few days old, may have helped as well.  Its an old flower holder/feeder. She worries that part of the problem may have been dryness from the hand watering we had been doing.

Well, my lettuce sprouts are dying. Of the four that spouted only one is left and is growing... straight towards the window. So, either the led modules are not putting out enough light or the light is the wrong color. To address this I designed a new module with almost double the LED density. The board will have 28 ultra bright blues in addition to 30 ultra bright reds. The chains have been reorganized into 6 in a row for red and 4 in a row for blue with an increased supply voltage of 15 volts. That reduces my future battery supply options, but to heck with it. I want growing lettuce!

In very short order our lettuce has sprouted! It actually sprouted several days before we left for vacation on Dec 29th, less than 10 days after we planted.

First light for my LED modules! I've settled on all the parts and designed the PCB. The picture above shows the very first PCB module operating. 27 more of these and I'll be ready to grow lettuce. Well, I still need to buy dirt ;)
