Preparing the Growing Environment
Choosing the Growing Container
When it comes to growing microgreens, selecting the right container is crucial. There are various options to choose from, including trays, shallow containers, or even repurposed items like old egg cartons or clamshell containers. The key is to ensure that your chosen container is wide enough to accommodate the seeds and has adequate drainage holes for proper water flow.
Consider the number of microgreens you intend to grow and the space available. If you have a small kitchen garden, a single tray or shallow container may be sufficient. However, if you plan to grow a wide variety of microgreens, a modular system with several trays might be more suitable. Ultimately, choose a container that fits your needs and allows for easy maintenance and harvesting.
Creating a Drainage System
Proper drainage is a critical aspect of microgreen cultivation. Excess water can lead to root rot or mold, potentially damaging your crop. To avoid these issues, create a drainage system in your chosen container. This can be done by drilling small holes in the bottom of the container or placing a layer of gravel or pebbles at the bottom to allow water to flow freely.
Remember to place a tray or dish under the container to catch any excess water that drains out. This will help keep your growing area clean and prevent water from flooding surrounding surfaces. Adequate drainage ensures that your microgreens receive the right amount of water without drowning in excess moisture.
Selecting a Growing Medium
Choosing the right growing medium is essential for the successful growth of microgreens. The medium provides essential nutrients and supports the roots of the plants. When selecting a growing medium, consider factors such as water retention, aeration, and availability.
One popular choice for growing microgreens is a soil-based growing medium, such as potting mix or seed starting soil. These mediums provide a good balance of water retention and aeration and are readily available at gardening stores. Another option is to use a soilless medium, such as coco coir or vermiculite. These mediums are lightweight, sterile, and have excellent drainage properties.
Providing Adequate Lighting
Proper lighting is a crucial factor in microgreen cultivation, especially when they are grown indoors. Not all windowsills provide enough natural light, so supplementing with artificial light sources is often necessary. When selecting lighting for your microgreens, consider the type of bulb, intensity, and duration of light exposure.
LED grow lights are a popular choice for indoor gardening, as they are energy-efficient and provide the right spectrum of light for photosynthesis. Place the lights close to the microgreens, approximately 4-6 inches above the plants, to ensure they receive adequate light for healthy growth. Provide a light schedule of 12-16 hours per day to mimic natural daylight, adjusting the timing based on the stage of growth.
Maintaining Optimal Temperature and Humidity
Microgreens thrive in specific temperature and humidity ranges, so maintaining the right environment is crucial for their growth. Most microgreens prefer a temperature between 60-75°F (15-24°C) during the day and slightly cooler at night. However, it’s essential to check the specific requirements of the microgreen varieties you have chosen, as they may vary.
To maintain the optimal temperature, consider using a thermometer to monitor the temperature in your growing area. If needed, use a small fan or ventilation system to control the airflow and prevent overheating.

A humidity dome or a misting system can help maintain the ideal humidity for your microgreens to thrive.
Sowing Microgreen Seeds
Preparing the Seeds
Before sowing microgreen seeds, it’s crucial to ensure they are of high quality and free from any contaminants. Purchase seeds from reputable sources or use organic seeds whenever possible. This will ensure that the resulting microgreens are not exposed to harmful chemicals or pesticides.
To improve germination rates, you can pre-treat the seeds by soaking them in water or hydrogen peroxide for a short period. This can help soften the seed coat and encourage quicker and more uniform germination. However, not all seeds require pre-soaking, so make sure to check the specific requirements of the seeds you’re using.
Soaking Seeds (Optional)
Soaking microgreen seeds is an optional step that can help promote germination. To soak the seeds, add them to a container or bowl and cover them with water. Allow them to soak for the recommended amount of time, usually around 4-12 hours. After soaking, drain the water and rinse the seeds thoroughly before sowing.
Soaking can be particularly beneficial for seeds with hard outer coats, such as basil or chia seeds. However, seeds such as lettuce or arugula may not require soaking. It’s important to follow the instructions specific to the seeds you’re using to ensure successful germination.
When it comes to sowing microgreens, there are various techniques you can use. One popular method is called the “spread and tamp” technique. This involves evenly spreading the seeds over the moist growing medium and gently pressing them down to ensure good seed-to-soil contact. This technique is ideal for smaller seeds that require minimal spacing.
Another technique is the “pre-moistened mat” method. This involves placing a pre-moistened growing medium, such as a paper towel or coco coir mat, on top of the container and evenly sprinkling the seeds on it. The mat retains moisture and provides a favorable environment for germination. Once the seeds have sprouted, the entire mat can be harvested.
Covering the Seeds
After sowing the microgreen seeds, it’s important to cover them to create a humid and dark environment that promotes germination. This can be done by placing a plastic dome or covering the container with clear plastic wrap. The cover should allow some airflow while retaining moisture.
Once the seeds have germinated and the sprouts have emerged, remove the cover to allow light to reach the plants. The cover can be reused for subsequent batches of microgreens or discarded after each harvest.
Caring for Microgreens
Proper watering is crucial in maintaining healthy microgreens. Overwatering can lead to root rot and mold, while underwatering can cause the microgreens to wilt and die. The key is to find the right balance and provide consistent moisture to the plants.
To water your microgreens, use a spray bottle or mister to avoid disturbing the delicate plants. Spray the soil lightly, ensuring that it remains evenly moist but not saturated. Avoid watering from above, as this can dislodge the seeds or damage the fragile sprouts. As the microgreens grow, adjust the watering schedule based on their needs and the moisture level of the growing medium.
Microgreens are typically grown for a short period, so they require fewer nutrients compared to mature plants. However, providing some additional nutrients can enhance their growth and nutritional content. Fertilizing microgreens can be done using organic fertilizers or liquid fertilizers specially formulated for young plants.
When choosing a fertilizer, opt for one with a balanced ratio of nutrients, such as a 10-10-10 NPK fertilizer. Start fertilizing the microgreens once they have developed their first set of true leaves. Dilute the fertilizer according to the instructions and apply it to the growing medium. Be careful not to over-fertilize, as this can lead to nutrient burn or stunted growth.
Monitoring for Pests and Diseases
Just like any other plants, microgreens are susceptible to pests and diseases. Regular monitoring can help you identify and address issues before they become detrimental to your crop. Inspect your microgreens for common pests such as aphids, fungus gnats, or mites. If an infestation is detected, consider using organic pest control methods or insecticidal soap to alleviate the problem.
Diseases such as damping-off, caused by fungal pathogens, can also affect microgreens. To prevent such diseases, ensure proper air circulation, avoid overwatering, and maintain cleanliness by regularly sanitizing your growing containers and equipment. If you notice any signs of disease, remove and discard the affected plants to prevent further spread.
Managing Air Circulation
Proper air circulation is crucial for the healthy growth of microgreens. Good airflow helps prevent the buildup of moisture and reduces the risk of fungal diseases. Positioning a small fan near the microgreens can help promote air movement and strengthen the plants.
However, be cautious not to direct the fan directly at the microgreens, as this can cause desiccation. Adjust the fan’s speed and direction to maintain gentle airflow without drying out the delicate foliage. A small oscillating fan or a gentle breeze from an open window can also provide sufficient air circulation.
Microgreens may be small, but they still need adequate room to grow. Overcrowding can lead to stunted growth, disease, and uneven development. When sowing the seeds, make sure to distribute them evenly, leaving enough space between each seed.
If you notice overcrowding as the microgreens grow, thin them out by gently removing excess plants. This will allow the remaining plants to have ample space and access to nutrients, resulting in healthier and more vibrant microgreens. Thinning can be done once the first true leaves have developed and are large enough to handle.
Determining the Right Time to Harvest
Harvesting microgreens at the right time is crucial to ensure optimal flavor and nutrition. The ideal harvest time varies depending on the variety of microgreens, but generally, it is when the first true leaves have fully developed and are vibrant in color.
Keep an eye on the growth rate of your microgreens and refer to the specific guidelines for each variety. As a general rule, most microgreens are ready to be harvested within 7-14 days after sowing. It’s better to harvest them a bit earlier rather than later, as they tend to be more tender and flavorful at the younger stages of growth.
When it’s time to harvest your microgreens, there are a few techniques you can use. One method is to use clean, sharp scissors or a small knife to cut the microgreens just above the soil level. Make sure to sanitize your tools before harvesting to prevent the spread of diseases. Another option is to gently pull the microgreens from the soil, but this method is more suitable for loose-leaf varieties rather than densely packed growth.
Once harvested, gently rinse the microgreens under cold water to remove any debris or soil particles. Shake off excess water and pat them dry with a clean towel or use a salad spinner for better results. Harvested microgreens are best consumed fresh, but they can also be stored under proper conditions for a short period.
Post-Harvest Handling and Storage
To prolong the freshness and shelf life of your harvested microgreens, proper post-harvest handling and storage are crucial. Once the microgreens are rinsed and dried, transfer them to a clean container lined with a paper towel to absorb any residual moisture.
Place the container in the refrigerator, ideally in the crisper drawer or in an airtight container to maintain freshness. Properly stored microgreens can last for up to a week, but it’s best to consume them as soon as possible to enjoy their full flavor and nutritional value.
