Increased Germination & Growth Rate in Lettuce

(Originally published in October 2013)

I was just digging around some old photos and I came across a couple of pics from my greenhouse last year… Check out the what’s possible with the energy from a single solar cell!

And then, 16 days later…

Electrified lettuce in bottom-right cell: increased germination & growth rate over all other cells.

As you can see, the solar cell pictured here, connected to the pot on the lower-right cell, had a significant effect on both the germination rate and growth rate.  The voltage used here was approximately 1.2 volts.  All seeds were started in a mix of Fox Farm & Black Gold potting soils.
