Office Farming : Growing Broccoli Microgreens Indoor

Broccoli is the healthiest microgreen for a beginner to grow. Compared to mature broccoli, broccoli sprouts contain anywhere from 10 to 100 times more sulforaphane and many more minerals like magnesium and zinc. While sulforaphane is a superior source of the cancer-fighting compound.

So let's try office farming!

Step 1: Container Preparation

Sanitize all the containers to grow the microgreens with hydrogen peroxide or bleach water. Follow the instruction of the label on the chemical bottle.

Step 2: Growing Medium Preparation

Pour organic soil into a plastic container and fill it up halfway. Microgreens don’t require a lot of nutrients to grow, therefore compost soil is not necessary.

Paper towel is another common medium to grow microgreen. If you are worried about the chemical of the bleached paper towel, feel free to use the unbleached one.

Step 3: Spread the Seed

Spread the seed densely over the top of the soil. Don’t worry about the density since we are growing microgreen, not a mature vegetable.

Some seeds require you to pre-soak a handful of seeds to promote early germination (follow directions on the seed packet). After the presoaking is complete, rinse and drain the seeds in a colander. If you’re worried about bacteria spreading from one seed to the rest, you can add a little hydrogen peroxide to the seed.

Step 4: Watering

Pour water into an empty container. Check the pH value of the water. The best pH value for microgreens to germinate is between 6 - 6.5.

Usually, tap water in the city is a little bit alkaline. You may correct the pH value with a little bit of lemon juice. Pour water into a spray bottle. Use a spray bottle to water the soil evenly.

Step 5: Covering to Germinate

Cover the seed with a black plastic container and place it in a warm (60 F - 85 F / 15.5 C - 29 C) space away from sunlight to germinate.

Step 6: Haversting

You can harvest your Broccoli Microgreens after 7 -10 Days.

    This seems rather patronising - why are you not addressing the author directly?

    Thanks for the write-up and photos and the video. I wish more people would try to grow some microgreens as they are so good for your health. I have made good microgreens using old, dirty clay pots and garden soil so some seeds are not that picky about what they need to grow but I am sure your method helps ensure more success for a multiple of different kinds of seeds.

    Around 2 - 3 days. Keep the humidity and temperature, then it will germinate fast.
    But also remember keep a good ventilation to avoid the mold problem.
