Introduction: Experiment to See If Green Onions Regrow Better in Water or Soil
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)?
This said, I will regrow my green onions. Thank you!
