Did you know that you can easily regrow green onions at home? All you need is a cup of water, soil and a little sun. If you already knew that you could regrow these vegetables at home, well I'm took it a step further. I did an experiment to see if green onions grow better in water or soil.

Step 1: Materials

  • green onions
  • glass of water
  • pot of soil

Step 2: Procedure

Place a set of green onions in a glass of water and the other in a pot of soil.

Step 3: Watch As the Onions Grow

Watch the video to see the results of this experiment.

Do you think the onions grew better in water or soil?

    Um, this is a good experiment. However, who just eats the tuff green tops only? I always ONLY eat the white part of the onions where the roots come out. That is the only part that is edible to me. I usually throw those dark green tuff tops away.

    What is more efficient, LED lights or halogen? If LED, what color(s)?
