At Agrotonomy, in our Tower Farms, we grow up to 52 komatsuna plants on a single aeroponic tower in less than one square meter of space while saving up to 95% water as compared to the conventional farming method.

Komatsuna, also known as Japanese mustard spinach, is a member of the Brassicaceae family, along with broccoli, bok choy, cauliflower, kale, tatsoi, etc. It is not related to spinacia oleracea or spinach, contrary to what it is called.

In Japanese, komatsuna means ‘greens of Komatsu’, a village in Edogawa, Tokyo named Komatsugawa, where komatsuna was exclusively grown during the Edo period.

When growing komatsuna on aeroponic towers, we begin by soaking the agricultural rockwool in water for about 20 minutes until it is fully wet. Rockwool is a soilless substrate made from basalt, the most common volcanic rock on Earth. It is often used in aeroponics and hydroponics as it allows for soilless germination. The rockwool comes with the tower when you purchase it.

Once the rockwool is completely soaked, we put three seeds into each hole of the tray. Each tray has 98 holes. Add vermiculite on top of each hole after the seeds have been placed. Vermiculite is a naturally occurring mineral that is ideal for the germination process. It retains a large amount of water while maintaining the perfect water to air ratio.

When germinating outdoors, the seedlings should be watered twice a day. After about two weeks, everything will start to germinate. The seedlings will then be ready for transplantation to the aeroponic towers using a grow clip to secure them in place.

It takes around six weeks of growth until the komatsuna reaches full maturity and becomes ready for harvest from the aeroponic towers.

Komatsuna is versatile, it can be enjoyed in various ways such as raw in salads, cooked as a side dish, or steamed to retain their vibrant color and nutrients—just like you would with other leafy greens.
