How to Grow Microgreens in a Jar

You can grow microgreens anywhere; that’s what I always tell people! They’re a great way to add nutrients and vitamins to your diet without buying supplements or spending a lot of money on top-selling greens.

If you’re looking for an easy way to grow microgreens, the best thing you can do is use a mason jar! Microgreens are nutrient-dense greens that pack a lot of vitamins and fiber into a small package. As a bonus, they are also very responsive to color, which means you can store them in any jar that strikes your fancy.

What is Microgreens

Microgreens are tiny, young plants that look and taste like full-grown vegetables. They’re perfect for those who want to grow their food but don’t have the space or time to grow large plants.

Microgreens are easy to grow and fast-growing, so they’re perfect for beginners just starting gardening. They’re also great for people who love to cook because they can be added to almost any dish, from soups and salads to sandwiches and omelets!

How to Grow Microgreens in a Jar
  1. Choose a wide-mouthed jar with straight sides that will hold enough water without leaking. The wider the mouth of the jar, the easier it will be to work with later on when transplanting your seedlings into the soil or soil-less potting mediums such as coco coir (which is made from coconut husks).
  2. Trim a piece of screen material to fit snugly over your jar’s mouth (the screen should be slightly smaller than the opening). Use tape or hot glue if necessary to secure it onto the inside of your lid so that no light can get through once seeds have been planted inside!
  3. Make your nutrient solution. Pour half of the jar of water and add 1 teaspoon of liquid seaweed (or liquid fish emulsion). Stir until dissolved and let sit for 24 hours before using.
  4. Arrange the seeds on top of the screen. Cover with more nutrient solution, and then place the lid on top. Put your jar on a sunny windowsill or under grow lights for 2 weeks, or until sprouts are about 3 inches tall and ready to harvest.
  5. After the seeds have been treated, cover them with a jar lid. Make sure there’s enough space between the top of the soil and the jar lid so that air can circulate freely through it.
  6. Keep your jar in a dark place for five days. After that time has passed, remove the plastic wrap and place the jar in direct sunlight for 10 minutes each day until it’s ready to be used.
  7. Remove the jar’s lid and place it in the sun or under a grow light. Then fill the container with water if it is required. You can use any water—distilled, bottled, or tap—but distilled will be best because it doesn’t contain any minerals that could affect the growth of your seeds.
  8. Fill the container with water if it is required. Many microgreens prefer to be grown in water instead of soil, which helps retain moisture and prevent rot during growth. If you have chosen to use a watering system for your microgreens, make sure you change their water regularly (at least once every two days).
  9. Harvesting is as easy as picking up your jar and eating some delicious little green treats!
