To prepare myself for sowing sunflower seeds on-site, I started a mini-experiment to see if sunflower seeds respond favorably to electrical stimulation. We happened to have 2 varieties of sunflower seeds on-hand since my pet parrot, Oskar, is a regular consumer of those seeds. The two kinds were a small black variety and the other was large and striped.
So using some organic soil, I planted 4 seeds, two of each variety into some square spice jars. While they really are a bit on the small size, not only because sunflowers grow very tall, but also because they have large root systems (which is helpful with regards to phytoremediation). On the other hand, I chose these containers because at least in the beginning, I could keep them sealed to minimize moisture loss when I was gone from them over the weekend (since I kept this mini experiment running at my office). Here’s a photo of the initial setup.
Then, as usual, the electrified seeds experienced major sprouting action within just 5 days!
And the growth continued even more:
And lastly, up to this point:
At this point, the pre-test is a huge success. I’m going to continue to watch these plants grow as I’m curious as to how long it will take the control group to get to the day 5 electrified state. As of now, the electrified group is well over 1 week ahead of schedule compared to the non-electrified group. A very promising feature that be useful for people who are worried about their plants not reaching maturity before the frost-season arrives. In our situation, that of contaminant removal, having a 1-week lead may have significant benefits with regards to the amount of lead that we can remove compared to the rest of the plot.
