Grow it Yourself

Geotropic Experiments

Excerpt from Wikipedia entry:

Gravitropism (or geotropism) is a turning or growth movement by a plant or fungus in response to gravityCharles Darwin was one of the first to scientifically document that roots show positive gravitropism and stems show negative gravitropism. That is, roots grow in the direction of gravitational pull (i.e., downward) and stems grow in the opposite direction (i.e., upwards). This behaviour can be easily demonstrated with a potted plant. When laid onto its side, the growing parts of the stem begin to display negative gravitropism, bending (biologists say, turning; see tropism) upwards.”

A good friend of mine and experienced carpenter, Matt Richard, helped to design and fabricate a rotating planter.  I was fretting about engineering a three-axis apparatus for a weeks.  Matt talked some sense into me, suggesting that I fabricate immediately, and settle for one-axis of rotation for a proof of concept.  After we finished the design, we realized that we could rotate the plant inside the holder, making it a dual axis planter.  Thanks Matt!

I have “before” picture on my phone.  Soon to come.

In the meantime, check out the result after ~ 1 wk!

Eureka!
