Microgreen Cultivation: Basic Information, Tips, the Importance of Grow LEDs, and Automation Solutions


Nowadays, the importance of fresh and healthy eating is felt more than ever. Especially in the fast pace of city life, being able to grow your own greens offers great advantages both in terms of cost and preserving nutritional values. This is precisely where “microgreens” have emerged as a cultivation method that has been rapidly gaining popularity.


In this article, we will discuss the basics of microgreen cultivation, the most popular microgreen varieties, the use and importance of grow LEDs, as well as automation and rack/monitoring system integration.

1. What are Microgreens?


Microgreens are small plants harvested once the seed (vegetable or grain) has germinated and the first true leaves (cotyledons) appear above the soil surface. They typically grow very quickly, in about 7–14 days, and they draw attention with their nutritional value. Being rich in vitamins, minerals, and antioxidants, microgreens not only add flavor to meals but also hold significant health benefits.


Advantages:

• Short growing period (7–14 days)

• Low space requirement (can be easily grown even in tight spaces)

• High nutritional value

• Easy to harvest


2. The Most Popular Types of Microgreens


Hundreds of different seeds can be grown as microgreens. However, some varieties are more popular due to their flavor and ease of cultivation:

1. Wheatgrass

• Known for its detox and immune-boosting properties.

• Frequently used in smoothies and health drinks.

2. Arugula Microgreens

• Slightly spicy, aromatic taste, often used in salads and as a garnish.

• Popular due to its fast growth and easy care.

3. Radish Microgreens

• Lightly pungent and sharp taste.

• Adds color to dishes with its purple and green tones.

4. Broccoli Microgreens

• Known for its cancer-protective compounds (such as sulforaphane).

• Has a mild, slightly sweet flavor.

5. Coriander Microgreens

• Especially popular in Asian and Latin cuisines.

• Its distinctive aroma greatly enhances dishes.

6. Basil Microgreens

• Sweet, aromatic scent, often used as a final touch in many dishes.

• Frequently used in pasta sauces, pizzas, and salads.


The list can go on, but these are some of the easiest and most preferred varieties for beginners.


3. Tips for Growing Microgreens

1. Choose the Right Seeds

Selecting the right seeds is the most critical step in microgreen cultivation. Opt for reliable sources or organically certified seeds.

2. Environmental Conditions

Temperature: The ideal range for microgreens is generally between 18–24°C (64–75°F).

Humidity: Keeping the soil or growing medium moist is important, but avoid overwatering that could lead to root rot.

3. Soil and Nutrients

You can use traditional soil mixes, cocopeat, or hydroponic systems. To enrich the soil with nutrients, you can add compost or organic fertilizers.

4. Watering

Microgreens need the soil to remain continuously moist, but excessive watering can lead to mold and rot issues. Using a spray method can offer better control.

5. Harvest Time

Typically, after 7–14 days, when the plants reach the first true leaf stage, you can harvest them with scissors. You can consume these microgreens immediately or store them in the refrigerator for a few days.


4. The Importance of Grow LEDs and What They Should Be Like


Lighting is a critical factor in microgreen cultivation. Even if you have a space with natural sunlight, you may need an additional light source during periods with limited daylight hours. This is exactly where grow LED lights come into play.

1. Light Spectrum

Plants require different wavelengths for development. Specifically, blue (430–460 nm) and red (630–660 nm) wavelengths are key to growth and photosynthesis in microgreens.

Blue light: Supports root and leaf development.

Red light: Influences processes like flowering and fruiting. In microgreens, it is mainly important for early-stage growth and color development.

2. Efficiency and Heat

Compared to traditional lighting, grow LEDs produce less heat and are more energy-efficient. This reduces the risk of scorching your microgreens and lowers long-term costs.

3. Adjustable Intensity

Being able to adjust the intensity of the light is crucial for controlled and high-quality produce. You can integrate timers or smart automation systems to provide the most suitable light cycle for the plants.

4. Distance and Height Adjustment

The distance between the LED light and the plants is important for growth rate and leaf quality. Generally, a distance of 20–30 cm (8–12 inches) is recommended for microgreens, but you should optimize it through trial and error based on the specific LED model used.


5. Automation, Racks, and Monitoring Systems


To make microgreen cultivation more efficient, professional, and scalable, you can use automation technologies. Thanks to innovative solutions offered by companies like Arkenstech.com, you can digitize these processes and manage them remotely with ease.

1. Automatic Irrigation Systems

• Drip or spray irrigation systems can be managed with automatic timers.

• Moisture sensors can regulate watering based on the soil or growing medium’s humidity level.

2. Smart Lighting Control

• Systems can be used to control the on/off times, light intensity, and wavelengths of grow LEDs.

• In seasons with limited daylight, this can significantly boost efficiency.

3. Rack Systems and Vertical Farming

• Rack systems can be used to save space.

• Each rack can be monitored and controlled independently. Especially in multi-level (rack) systems, it’s possible to grow different plants on each level.

4. Sensors and Data Tracking

• Sensors measuring temperature, humidity, CO2, etc., can be integrated into automation systems to maintain ideal growing conditions.

• Remote access allows you to monitor every stage of production in real-time via mobile or web.

5. Remote Management and Alarm Systems

• With real-time data tracking, notifications (for excessive heat, insufficient humidity, etc.) can be sent to a phone or computer if a problem arises.

• Quick intervention significantly reduces product loss.


6. Why are Automation and Integration Important?

Time Savings: Especially beneficial for commercial producers.

Increased Efficiency: Controlling all parameters (light, watering, temperature, humidity, etc.) from one system helps achieve maximum yield.

Consistent Product Quality: With automation, you can obtain products of the same standards in every batch of cultivation.

Easy Scalability: It’s possible to increase capacity from small spaces to large facilities using similar systems.


7. Conclusion


Microgreen cultivation is an excellent option for anyone looking to harvest crops in a short period, with high nutritional value and great taste. With the right seed selection, environmental control, and high-quality grow LED lighting, achieving success becomes much easier. For those wishing to increase production capacity and streamline processes, automation systems, rack solutions, and sensor-based monitoring are highly effective investments.
