Microgreen Farming : Growing Tiny Greens

Microgreen farming simply stands for Micro means “small”, Green means “plant /herb/fauna” and farming means “cultivation”. They are immature plants, grown within period of 6 to 10 days only and can be harvested by trimming them from stem grown at 2-3 inches of length. A widely accepted definition of microgreens “Microgreens are tender young greens derived from vegetable and herb seeds. They are characterized by fully developed cotyledons and may or may not have their first true leaves”. These greens are prized for their intense flavor, vibrant colors, and concentrated bioactive compounds, making them an excellent choice for enhancing the appeal of various dishes and salads.

Edible Parts of Microgreen:

The stem, leaf and cotyledons are considered as the edible parts of microgreen, which is highly nutritious, contain utmost nutrition of their whole life cycle stages. They can be easily harvested after 14 to 20 days only. It’s a most profitable farming process where small plants are grown at very small place at tray or pot. It’s farming & handling methods are easy, if once understood and it may pronounced as “urban farming” with great health benefits at very low handling cost.

Origin of Microgreen farming

It has been found that the history of Microgreen farming was rooted back in 1980s when it first seemed on the menu of chefs in San Francisco, California (United States Department of Agriculture, 2014). Further popularity began in the southern part of California in the 1990s, such that now microgreens are regarded as “functional foods” or “Superfoods.”

Techniques of Microgreen Farming:

The simple and proper techniques for Microgreen Farming are :

  • Prepare the Container: Fill a shallow tray or container with soil, with a depth of about 3-4 inches, as microgreens have shallow root systems.
  • Seed Sowing: Evenly spread microgreen seeds on the soil surface. There’s no need for precise spacing; hand sprinkling works well. You may use more than one crop seed at the same tray.
  • Cover and Pat Down: Gently cover the seeds with a thin layer of soil (1 to 2 inches ) and pat it down to help the seeds settle. Moisten the Soil: Spray water over the soil to ensure it’s moist, but avoid overwatering.
  • Germination: Place the container in a room with room temperature for approximately two days to allow germination. Once sprouts appear, move it to a sunny spot with 3-4 hours of sunlight daily.
  • Regular Watering: Water the growing greens twice a day. In 3-4 days, small leaves will develop above the soil with shoots at the base.
  • Harvest: When the microgreens reach a height of 2-3 inches, they are ready for harvesting. Use scissors or a sharp knife to cut them, holding them vertically just above the roots.
  • Rinse and Use: Wash the harvested microgreens with cold running water and use them immediately in your meal. The fresher, the better. It’s advisable to dry them gently before use.

Types of Microgreen Farming:

Basically, two types of Microgreen Farming Systems can be created, either it can be Kitchen Microgreen Farming or Indoor Microgreen Farming and Hydroponic Microgreen Farming System.

Kitchen Microgreen Farming or Indoor Microgreen Farming:

  • Coconut Husk or Plastic Trays: These trays serve as the growing medium for your microgreens. You can use coconut husk or plastic trays, which provide support and a place for the seeds to grow.
  • Water Spray Bottle: A water spray bottle is essential for gently moistening the growing medium and keeping the microgreens adequately hydrated. It allows you to control water distribution without disturbing the delicate seedlings.

Hydroponic Microgreen Farming System:

A hydroponic microgreen system allows you to grow microgreens without soil. This typically involves trays or channels where the plants receive a nutrient-rich water solution directly, promoting rapid growth. These trays should have an appropriate depth to accommodate the roots.

  • Nutrient solution: Hydroponic microgreens require a carefully balanced nutrient solution to provide essential elements for growth. This solution typically contains water, macro, and micronutrients crucial for the development of healthy plants.
  • Water Pump and Aeration: Hydroponic systems include a water pump and aeration system to ensure the even distribution of the nutrient solution and oxygen to the roots of the microgreens.
  • Grow Lights: Since hydroponic microgreens may not receive natural sunlight and hence need grow lights to provide the necessary light for photosynthesis and growth.
  • pH and EC Meter: Monitoring the pH (acidity) and electrical conductivity (EC) of the nutrient solution is crucial to maintain optimal growing conditions for your microgreens. Hydroponic Microgreen Farming generally performed at lab or large scale industries.
