Neat Idea for Growing Vegetables

Thursday, April 2nd, 2009

A semi-conductor executive has come up with an affordable ‘closed loop watering system’ for vegetable gardens. It uses 75% less water than traditional vegetable gardens. This is great for people with patios or poor soil conditions like we have have here in coastal southern California. It seems like like this would work well for the very arid regions like Africa. Because it’s in a container the plant can be moved.

Unlike manual or drip irrigation top watering, the EarthTainer employs a bottom up, automated watering approach based on the principle of capillary action. Water stored in the lower reservoir is wicked up into the soil much like the wick in a candle draws the liquefied wax upward to the flame. Moisture meets the roots of the plant where the plant “drinks” just as much water as it needs. This water consumption will vary significantly throughout the growing season as the plant produces fruit, and by providing a constant supply of water from the reservoir, the plant can achieve optimal growth and productivity.

Water Conservation

Monday, March 23rd, 2009

In southern California we receive only about 9 inches of rain per year. This article touches on gray water systems. In this arid climate I’ve always wondered why newer homes were not required to have these types of systems when they were built.

To get a permit to install this type of system at an existing home is no small feat. It involves “filing detailed documents, submitting soil percolation data and completing an inspection.”

Weller drains his washing machine into a 55-gallon plastic drum that’s placed on a cart. Then he wheels the container around his yard and waters his plants.

Weller started the system about 10 years ago to conserve money and water.

“I am not paying for fresh water to water my grass and roses,” he said. “I am using the water I already paid for.”

Weller’s operation isn’t up to code, but he doesn’t care.
