How To Grow Microgreen Indoor

Microgreen is one of the best and fast-growing crops, which offer a palette of fresh flavors, range from mild to spicy in taste and encourage repeated planting for an ongoing supply of fresh greens and also for creative uses. Here in this article, I will tell you how to grow microgreens indoors.

These tiny microgreen plants can be grown for early harvest at a young stage and are perfect for a windowsill garden. They are ready for harvest and may have their stems snipped after only two to a few weeks of growing. If they left at an early stage, then microgreens become young seedlings then turn into full-fledged plants. For growing microgreens indoors you will need a potting mixture and full bright light. Flavors range from intense sort of a full-grown plant to subtle.

What are microgreens?

It is also known as vegetable confetti. With sprouts, you eat the fully germinated seed. I believe in sprouts because of the babies of the plant world. A seed that bursts open with the primary root and shoot. Whereas sprouts are seeds that germinate by being soaked and rinsed in water, microgreens are grown in soil. During seed germination, the cotyledon or seed leaves emerge from the soil first. A cotyledon is a component of the embryo within the seed of the plant. Through photosynthesis, the cotyledon provides initial food to provide the plants a burst of energy for truth leaves to develop.

A microgreen is the following stage in a very plant development, which is quite just like the toddlers of the plant world. Microgreens will be harvested when the germinated seeds have developed tiny roots and a minimum of their first true leaves. They need similar health benefits to sprouts but greater nutritional value.

Benefits of growing microgreens:

Here are certain benefits of growing microgreens.

Quick to grow: Depending on the choice of variety it takes just 1-3 weeks to grow completely.

High yield to space ratio: You can grow an unbelievable number of plants in an exceedingly tiny area.

Minimal cost: It required less cost and less effort for fast food and a healthy harvest of organic green.

Urban gardening: it is a perfect solution for urban living and folks with no room or time for a garden.

Minimal requirement: You just need access to good light, a tray, suitable shallow container, water, and a growing medium.

Suitable to climate: Produce fresh living greens for salads, sandwiches, soup, and garnishes within the heat of summer or cold of winter. In our subtropical summer, microgreens are an answer to salad ingredients when lettuces, rocket arugula, and spinach crops tend to bolt to seed within the heart.

Nutrient-dense food: Microgreens contain digestible vitamins, minerals, and phytonutrients that provide a large style of nutritional health benefits. They are filled with flavor, color, texture, living enzyme and nutrients.

Variety of flavors: Microgreens have a fragile crunchy texture and might be used as garnishes to feature flavor and color.

Fantastic value: Many varieties will regrow and produce several harvests.

The requirement for indoor planting:

Here are the following tools which you required indoor planting.

  • Garden trowel
  • Watering can
  • Suitable container or trays
  • Soilless seed starting mix
  • Vermiculite
  • Certified Seeds
  • Plant labels
  • Plastic wraps
  • Spray bottle
  • Seaweed solution
  • LED light

Steps to grow indoor:

There are certain steps to follow while growing microgreen indoor.

Selection of container:

Select a shallow plastic container with drainage holes like a nursery flat or prepackaged salad box which is either clear or opaque will work. Fill the container with 1 ½ – 2 inches of moistened potting mix. Cut a bit of cardboard to suit inside the container. Gently press the cardboard onto the soil to make a flat even surface.

Use a growing tray and if it does not have holes already within the bottom then add some drainage holes with a pair of sharp scissors, being careful to not cut yourself. Just stick this growing tray into another growing tray with no holes. This can let the moisture drip through to the container and also the second tray will act as a saucer.


If the area during which you are growing the microgreen has good sunlight, you will need a minimal amount of supplemental light. Some micros require more light and some not as much, your best guide is to read a courant the crop you are choosing to grow. Altogether cases, remember you merely have to get the crop getting down to make true leaves. If the merging crop is leggy it needs more light. If growing in racks stacked, then supplemental light is needed for those shelves that do not have access to natural light. If the leaves exhibit spots, your light is perhaps too close.

A basic very cost-effective method of accomplishing this can be to use two 48” LED light bars per shelf occupied by 10” ×20” flat and microgreen trays. LED lights to provide an efficient means of providing a full spectrum of sunshine to microgreens and are available in many shapes, sizes and prices. For the beginner, use what you have got round the house, shop lights clamp on with LED bulb together with incandescent light, just concentrate on your plants and they will tell you the way you are doing.

Which microgreen grows?

The growing immature seedling will be grouped into three categories.

Sprouts: Sprouts are defined as plants that have just sprouted their hypocotyl and also the seed remains on the bulk of the sprouts to be harvested.

Microgreens: Microgreens are harvested at the primary true leaf stage.

Baby salads: this may be the stage the plants develop to if left to grow within the media for a pair of weeks sometimes longer then the past microgreen stage because the name implies they resemble a baby size of the total grown plant.

There are actually dozens of plants that may be grown as microgreens. When deciding which of them to grow, you ought to start by growing the simple ones, and choose which media they grow best in.

Prepare seed:

To help your seeds germinate quickly, pre-soak larger seeds e.g. mung beans, wheat, peas, beetroot and sunflowers in warm water for some hour or overnight.

Prepare container and seed mixture:

If employing a tray, lay some moistened towel or chux cloth on the underside to prevent the combination of falling through. Fill your container about ¾ stuffed with the moist growing medium about 2-3 cm deep.

I make my very own handmade seed raising mixes because they contain key ingredients to spice up seed germination. Once seeds sprout, the ingredients take advantage of in my very own seed raising mix provides additional nutrition to grow healthy microgreen leaves and minerals to spice up health. That way, I do know I am eating the foremost nutrient-dense food possible.

The seed raising mixture which you use in your tray should be moist like a sponge that is not too dry or wet. You could also use a licensed organic seed raising mixture just spread the seed raising mixture evenly, even you can use paddle pop stick and ruler for making the surface even.

Growing media:

There are different growing media used for indoor plantation.

Soil-based media: It is used as a planting mix that drains well, is freed from clump and stones and does not compact easily. Since you are harvesting the crop at about 1-3” tall, it is not critical to own lots of nutrients within the soil mix, so adding any nutrient should be done conservatively. You will want to stay the surface of the soil damp, but in many cases keeping the too wat soil may cause trouble with micros.

Soilless media: It is comprised of various non-soil mixes. Coco coir, blends of vermiculite and perlite with an organic amendment or hydroponic lava rock are samples of soilless media. They will be leveled and lightly firmed so you will be able to have a clean surface which is very important at the time of year. This can be a pleasant compromise choice between soil and hydroponics because the surface of the soil is cleaner than soil media.

Hydroponic: This method with microgreens at the beginner level is incredibly simple, clean and easy. It involves the employment of a growing pad that absorbs and retains water so on keep the germinating seeds and emerging greens continually moist. When done correctly, your crop is easy to reap and you will be able to cut right to the growing surface or maybe pull the crop right out of the pas and trim off the seeds and roots making for a far easier harvesting process.

Filling container:

Fill each container and growing tray with remoistened seed starting mixture. Always must pack it into place packing the container too tight will cause drainage issues and ultimately cause root damage. Set the container on a watertight drip tray or saucer.

Sow seed:

Sprinkle seeds evenly over the surface of the seed starting mixture, sowing them more thickly than you ordinarily would. Always maintain a minimum of ¼ inch of space between the seeds. Lightly irrigate by misting with a twig bottle. This will prevent you from dislodging the seeds. Place a drainage tray on a saucer during a warm spot like your kitchen bench.

Cover seed:

After sprinkling, cover the seed with vermiculite. Next is to create a warm humid environment for the seeds to germinate just cover the seed with a punnet lid or add a transparent bag over the top of the tray with holes snipped within the top for airflow. This mineral-based material absorbs water and releases it slowly, keeping the seeds damp but not too wet. Follow the instructions for planting depth provided on the seed packet. Some seeds should be barely covered; others need thicker covering to germinate well.


Keep the media moist could be a good rule of thumb for seed growth. Employing a mister allows you to accomplish this. Watering a soil medium are often tricky to stay splashed soil off the leaves. Watering a hydroponic pad is easy you just lift the pad, pour in water enough to return to the tops of the ridges within the bottom of the tray. Ensure it is distributed across the whole tray.

Irrigate the sown seeds with a mild shower that soak the vermiculite without washing away the seeds. Until the seeds germinate and green shoots sprout from them, water it lightly as per the requirement to avoid the damping of seed starting mixture. If the growing medium becomes too wet, then the seed cannot root out and fail to grow.

pH balance in all water sources:

In most cases, especially in municipal water sources, your water is too high in pH. Just use a pH testing kit that may test from pH 4-8. The optimum pH level for microgreens water is about 6. Most municipal water system will have a pH of around 7. An honest guide when using juice to acidify is about 2 teaspoons of juice per gallon of water.

Covering the plants:

To simply facilitate the growth of microgreen indoor, just cover the containers with a lightweight sheet of plastic or a doomed like a lid to take care of humidity and promote germination to set the drip tray on a heat mat designed for seed starting or on a hot pad.

Care for plant:

When the seeds start germination then remove the lid and also the heat source. Set the containers on a sunny windowsill to assist your microgreens growing indoors. Always keep the planting medium damp, and promote healthy growth by watering from the underside. Pour water into the tray and permit it to be absorbed into the soilless medium.

Harvesting and storage:

When the seedlings are about 2.5-10cm tall-depending on the variety you choose, your yummy microgreens are ready for harvesting. To harvest the microgreens, hold a bit with one hand and use the opposite to snip with scissors. Keep your microgreens cool and in an airtight container until you are able to use them. Their period of time within the refrigerator is a couple of weeks.

Hopefully, now you are able to grow your own microgreens indoors and enjoy their fresh and delicious taste.
