  • Using a light mist of water, lightly spray the seeds and cover your container with a plastic lid.

How Actually Onion Microgreens are Grown?

#1. Soaking:

The seeds of onion are very small and generally, people don’t soak them before planting but a couple of hours soaked in water may help them germinate faster and the output will also be good.

#2. Planting

To begin, put several drainage holes in a growth tray and fill it nearly to the top with dirt. Wet the dirt with the spray bottle and pack it down. We’re all set to start sowing seeds!

Distribute your microgreens seeds evenly throughout the soil surface, including the tray’s corners (you may want to use a shaker bottle). The seeds should be in close proximity to one another. You must, however, guarantee that they are not contacting one other.

Onion seeds, when grown too close together, produce the ideal environment for fungal development in the soil. Instead of covering the seeds with dirt, leave them exposed. Give your onion seeds a nice spritz of water after planting to help them germinate, and then lay the second tray directly on top of them (right side up).

While pushing the onion seeds into the earth, this produces darkness for them to grow in. To guarantee that no light reaches the seeds, you can add up to 5 pounds of weight to the cover. When the onion microgreens begin to develop after germination, they will collectively push up the cover and weight.

#3. Growing

Keep your seeds in the dark for at least 3-4 days after they’ve been planted. During this period, they don’t require water. Remove the seed cover once the seeds have grown into seedlings and are yellow in colour. The sprouts may appear squashed at first, but in the light, they will rapidly rise (and turn green).

Directly beneath the grow light, place your onion microgreens. Because the shoots grow towards the light, we choose artificial light for indoor microgreen growth. The microgreens will develop unevenly if the trays are merely put on a windowsill. You’ll also be able to manage how much light the trays receive each day with a grow lamp (we recommend 8-12 hours).

#4. Harvesting

Onion microgreens have a longer harvest shelf life than most. You’ll be able to harvest in stages rather than all at once (though you can certainly do just one big harvest). However, keep in mind that the flavour of the microgreens will alter as they grow, so don’t wait too long.

As the onion microgreens grow, the tips of the microgreens may dry off. Harvest your onion microgreens when they reach 4 inches in height and begin to lean over (they’ll resemble unmowed grass). Clip the onion microgreens in bunches at least 12 inches above the soil surface with clean kitchen shears (or something similar).

Instead of growing from the top of the stem, onions grow from the bottom. This implies we’ll be able to get another crop out of the trays. Simply continue to care for the microgreens until they regenerate and may be picked once again.

#5. Storing

After harvesting the onion microgreens, don’t wash them until you’re ready to utilize them. As previously stated, the seed husks can be left on or removed from the onions. Whichever green you select, you’ll get a great onion taste with no effort (they won’t even make you weep when you cut them!).

Keep your microgreens, onion, or otherwise, in the fridge in a sealed container. They should last for up to a week if you put a paper towel in the bag to absorb any excess moisture.

This is your journey of growing onion microgreens.
