Mason Jar Microgreens: From Seed To Harvest


Growing microgreens in mason jars is a simple and rewarding way to enjoy fresh, nutritious greens at home. With a few supplies and a little care, you can go from seed to harvest in just a week. Here’s how to get started and enjoy the process!

Supplies You’ll Need

  • Wide-mouth mason jars
  • Microgreens seeds (sunflower, broccoli, radish, or alfalfa work well)
  • Cheesecloth or fine mesh
  • Rubber bands
  • Fresh water

Step 1: Soak the Seeds

Begin by soaking your seeds in water for 6-12 hours. This kickstarts the germination process by hydrating the seeds. Use about 1-2 tablespoons of seeds per jar.

Step 2: Prepare the Jar

Cover the mouth of the mason jar with cheesecloth or mesh and secure it with a rubber band. Drain the soaking water through the cover and rinse the seeds thoroughly. Make sure all excess water is removed to avoid mold.

Step 3: Rinse and Drain Daily

Place the jar at a slight angle with the mouth down to ensure proper drainage and airflow. Rinse and drain the seeds twice a day. This keeps them moist and prevents stagnation, which can lead to spoilage.

Step 4: Provide Light

Once the seeds start sprouting (usually within 2-3 days), place the jars in indirect sunlight or under grow lights. Rotate the jars daily for even growth.

Step 5: Harvest Your Microgreens

In 5-7 days, your microgreens will be ready to harvest. When they reach 1-3 inches tall, use scissors to snip them just above the seed level.

Final Thoughts

Growing microgreens in mason jars is a sustainable and fun way to add a fresh boost to your diet. Start your journey today and enjoy nutrient-packed greens in every meal! 🌱🫙
