Cut store bought or home grown green onions about 1-2 inches above the root. Place in the Green Onion Pods. Then place the Pods in AeroGarden or a Kratky Jar. Follow your AeroGarden liquid nutrients instructions.
To harvest, simply cut the tops off the green onions with a pair of scissors about 1-2 inches above the root. The green onion will continue to grow and produce food for your table.
It takes about a week to re-grow your green onions. And you should be able to harvest it at least 3-5 times before replacing them.
If using very thin green onions, use a toothpick through the side holes (cut to fit) to help hold very thin green onions in place till roots start to form.
