I think it's about time we see a progress pic!
I'll take another pic tonight. Hopefully it has grown noticeably.
Here is a pic from a water damage check yesterday. I'm not sure how I feel about my LED choice, but I think it will look better once the sprouts are taller and darker green.

More importantly, despite all the watering, the pedal still works so far!
I'm watering the plants using a plastic medicine syringe now. It allows me to keep the water out of the critical areas above the threaded bushings of the switch and pots.
I started these seeds on February 18
th, by the way.
