Cut the Napa cabbage into 1 1/2" pieces.
In a large bowl, dissolve the salt in 3 cups of water. Add in the Napa cabbage. Let soak for 2 hours. Now is a great time for bong rips.
Rinse the cabbage at least 3 times. Make sure to get rid of as much excess water as possible.
Mix all of the Kimchi seasoning ingredients together.
Mix together in a large bowl the Napa cabbage, green onions, and the kimchi seasoning. Make sure that all of the cabbage is evenly coated. For best results, mix this by hand with kitchen gloves.
Place the kimchi in an airtight jar or container. Let sit out at room temp for at least 12 hours. Then store in the refrigerator and let ferment for at least 3 weeks before consumption.
