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…
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.
