Fun Experiment to Grow Green Onions (Part I)

Green onions are often called scallions or spring onions are immature onions. They are used as vegetables, eaten either raw or cooked. They have milder taste than most onions. I used to cook them to make soups or any broths or just pour them (slices) on the top of the soup/broth.

I had an idea several months ago to do experiments: planting them inside and outside. I wanted to see the differences between growing inside and outside with different purposes. For inside: I planted them in the water (hydroponic system) and harvested the green leaves twice. For outside: I planted them in the containers/plastic pots using pot soil as their media. I wanted to see their flowers growing and would harvest the real onions (bulbs).

The first day after planting (Hydroponic).
Media: water. I changed the water at least once a week.
 Everyday the old and new leaves grew 1 cm.
This small plastic glass contains 3 green onions.

Growing after 2 weeks. Location to grow: Near window with full of sunshine.
Time to harvest.

This plastic container contains 6 green onions.
Every time I harvest, I have saved $1.18 as like buying them in one plastic back.
To harvest: I cut the green leaves and let the bulbs growing again one more time.
By harvesting twice, I have saved $2.36 as like buying them in two plastic bags.

In the second harvest I used all the parts of the green onions (leaves and bulbs) and only left two bulbs.
I did another experiment by planting them in the plastic pots using pot soil as their media.
