Growing Plants on the Moon May Be Feasible

Smivs writes "European scientists say that growing plants on the moon should be possible. Scientists in the Netherlands believe growing plants on our sister satellite would be useful as a tool to learn how life adapts to lunar conditions. It would also aid in understanding the challenges that might be faced by manned bases. 'The new step, taken in the experiments reported at the EGU, is to remove the need for bringing nutrients and soil from Earth. A team led by Natasha Kozyrovska and Iryna Zaetz from the National Academy of Sciences in Kiev planted marigolds in crushed anorthosite, a type of rock found on Earth which is very similar to much of the lunar surface. In neat anorthosite, the plants fared very badly. But adding different types of bacteria made them thrive; the bacteria appeared to draw elements from the rock that the plants needed, such as potassium.'"

Sunlight is the Biggie

[StCredZero]

Sunlight is the biggest problem. Most places on the Moon go through two weeks of darkness, and providing sunlight-equivalent illumination would be energy prohibitive. Soviet scientists have experimented with keeping plants on low artificial light at low temperatures for two weeks, alternating that with two weeks of light. Apparently, peas can grow like this.

You do know that people have been growing plants in mineral solutions for years don't you?

You will only need a source of Co2 which could be delivered from the earth and use a sealed glasshouse (greenhouse) to conserve the ecosystem.

After you have got "enough" oxygen from the plants you can then send some lambs and rabbits to produce more Co2 for the plants.
