You can grow green onions easily in an Aerogarden. Just purchase some green onions from the grocery store, and plant them in an Aerogarden Harvest using Green Onion Aerogarden Pods ($14).
Green Onion Pods For An Aerogarden
These are third-party pods available on eBay that are designed to re-grow green onions. The pods are printed with a 3D thermoplastic polyester, which is non-toxic and biodegradable. The pods are reusable.
To harvest, cut the tops off the green onions with a pair of scissors about 1-2 inches above the root. Since the roots are trimmed and clean, it will take a few weeks for the onions to start growing in earnest.
Once the roots are regrown, the onions will regrow in a week. You can harvest the green onions 3-5 times before replacing them. If using very thin green onions, use a toothpick through the side holes to help hold the green onions in place till roots start to form.
Adding A Grow Tent
You’ll also notice I’ve added a reflective “tent” over the Aerogarden. This is a “Hydroponics Mylar Grow Tent” ($10). It reflects the LED light on the plants and increases the growth rate. It is said to provide 98% grow light reflection. It is equipped with a visual mesh window, which ventilates the plants and allows you to monitor their growth.
