Planting by moon phases -- make any sense?

The very first Jack Horkheimer Star Hustler episode (1976) mentioned planting crops with respect to Moon phases. I got to thinking, and most googling turned up sites like this, which make claims like

Quote:

In the second quarter the gravitational pull is less...After the full moon, as the moon wanes, the energy is drawing down. The gravitation pull is high, creating more moisture in the soil, but the moonlight is decreasing, putting energy into the roots...

...which sounds like a lot of woo to me.

Even Wikipedia says, under Agricultural astrology:

Quote:

Moon gardeners maintain that not only is science on their side, but also that the results are plain to see. According to the theory, plants that are sown in the few days before a full moon become stronger and more productive. The moon gardeners claim that the gravitational force of the full moon affects the level of groundwater in the soil, just as it does the level of the oceans. With more water being drawn up into the soil during a full moon, any newly-sown seeds are boosted by the increased hydration.

So was Jack (RIP) full of it, or is there anything here beyond wishful thinking and self-deception?
