How to Germinate Microgreens

Growing your own microgreens is relative straightforward and easy to do. With just a few supplies, you can cultivate them right at home . Use a shallow container with moist soil, sprinkle seeds evenly, cover with a lid, and keep them in a warm room. Mist regularly and watch your nutritious greens sprout in just a few days!

To get the best possible germination for you micro its important to consider the seeds you use, the soil,darkness and the temperature.

If you have these main factor in place you should see results in 2-7 days depending on the vairation you use. 

The other challenge you need to consider is that you risk geting mold if you keep the temarature and moisture to high to long. So make shure the you are in the “goldielock” zone for watering and humidity. .

Basil	7-14 days	No	70-75°F	21-24°C
Cilantro	7-14 days	No	70-75°F	21-24°C

I generally recommend soaking large seeds for 12 hours before germination. This is a way to speed up the process and increase the success rate.

Sprinkling the Seeds

Start by preparing your growing medium, which can be soil, coconut coir, or a seed-starting mix. Once your medium is ready, take your seeds and gently sprinkle them evenly across the surface. It’s important to space them out to avoid overcrowding, which can lead to weak plants. Aim for a consistent coverage, allowing each seed enough room to grow without competing for space.

Gently press the sprinkled seeds into the growing medium, ensuring they bond closely for optimal moisture absorption.

Creating Darkness for Germination

Most seeds require darkness to trigger the germination process.(Popcorn is one exeption..) You can achieve this by placing a tray on top of the seeds or using a blackout dome.

If you’re using trays, simply place one of them over the seeds to block out light. This not only helps keep the seeds in darkness but also creates a mini-greenhouse effect, retaining warmth and moisture. If you have a dome, place it over the growing tray. This will serve a similar purpose, providing an enclosed environment that encourages germination.

Maintaining Humidity Levels

Keeping humidity levels high is key to successful germination. When you cover the seeds with a tray or dome, you trap moisture in the air, creating a humid environment that is ideal for seed sprouting. This high humidity prevents the seeds from drying out and encourages them to germinate more efficiently.

Make sure to check the moisture level regularly. If you notice that the growing medium is drying out, lightly mist it with water to maintain the humidity without soaking the seeds.

Germination Rates

For quality seeds, the average germination ratio is typically between 80% and 95%. This means that most of your seeds should sprout successfully if you provide them with the right conditions. 

After the initial germination process, it’s essential to provide the right environment for further development and expansion.

 

Choosing the Right plants

When it comes to microgreens, each variety presents a unique taste experience, ranging from subtle and delicate to bold and spicy. Popular options include arugula, cilantro, kale, broccoli, and sunflower sprouts. It’s essential to consider your flavor preferences when selecting which seeds to grow for your own harvest of fresh greens.

The time required for microgreens to mature varies by seed type. If you’re looking for quick results, opt for varieties with shorter growth times, such as radish or mustard greens. On the other hand, if you have a bit more patience and prefer a longer-lasting harvest, consider slower-growing options like basil or chia.

Each microgreen variety offers its own unique nutritional benefits, thanks to its specific blend of vitamins, minerals, and antioxidants. For instance, arugula is rich in vitamin K and folate, while cilantro boasts high levels of vitamins A and C. Kale is packed with iron and calcium, and sunflower sprouts provide an excellent source of protein.

While most microgreens are easy to grow, even for beginners, some varieties may require more attention or specific growing conditions. If this is your first time cultivating microgreens, or if you prefer low-maintenance plants, start with foolproof options like sunflowers or peas.

Consider factors such as available space—whether indoors or outdoors—as well as lighting conditions, which can range from natural sunlight to artificial grow lights. For example, sunflowers thrive in bright sunlight, while cilantro and parsley prefer cooler temperatures.

Think about how you plan to use microgreens in your meals. Certain varieties complement specific dishes or cuisines beautifully. For instance, arugula adds a peppery kick to salads and sandwiches, while cilantro is a staple in Mexican and Asian cuisine. Additionally, radish microgreens offer a spicy crunch that enhances tacos or stir-fries.

Meals ideas

Have you ever thought about how growing your own microgreens can enhance your meals?

Each type  has its own unique nutrition profile. For instance, arugula microgreens are loaded with vitamin C and potassium, while cilantro microgreens are packed with vitamin K and beta-carotene. Boost your health with vibrant microgreens, packed with essential nutrients for a diverse and optimal diet.

1. Amp up the freshness and crunch of your favorite salad by tossing in a handful of microgreens. They complement leafy greens like spinach or arugula, as well as heartier options like kale or radicchio.
2. Take your sandwiches to the next level by sprinkling it top of the fillings. Their refreshing taste adds depth to even the simplest sandwich.
3. Sprinkle it on hot soups or stews just before serving for an added visual appeal and delicate texture that balances out the richness of the dish.
4. Boost your morning omelette or scramble with a small handful of microgreens for extra nutrients. Their mild flavor pairs perfectly with eggs, creating a harmonious blend.
5. Blend microgreens into your smoothies so you can add vitamin and mineral boost  – perfect for picky eaters who may not enjoy whole greens.

Nutritional benifits

• Arugula  is rich in vitamin K, supporting bone health and blood clotting.
• Cilantro  contains antioxidants that protect against cellular damage.
• Sunflower have essential nutrients like vitamin E, selenium, and zinc which support immune function.
• Kale are ritch in Sulforaphane that have many doucmnted benifits.

Remember to harvest  right before using them for maximum freshness – rinse gently under cold water then pat dry with a paper towel before use.

Microgreens are not just a trendy garnish; they are a powerhouse of nutrition. For instance, broccoli microgreens have been shown to contain up to 50 times more sulforaphane than mature broccoli, a compound known for its cancer-fighting properties. This makes them an excellent addition to any health-conscious diet.

When growing microgreens, consider the method that best suits your lifestyle. Hydroponic systems can yield faster results, but they require more initial setup and maintenance. In contrast, soil-based growing is more forgiving and easier for beginners. Experimenting with both can help you discover which method you prefer.

Moreover, don’t overlook the unique varieties that can elevate your dishes. Pea shoots add a sweet, fresh flavor to salads, while mustard greens bring a spicy kick. Incorporating these into your meals not only enhances flavor but also boosts your intake of essential nutrients.

Q&A 

Can I use tap water to water my microgreens?

Yes, you can use tap water, but it’s advisable to let it sit out for a few hours to allow chlorine to dissipate. If you’re concerned about chemicals in your tap water, consider using filtered or distilled water.

What lighting is needed?

To thrive, microgreens crave 12 to 16 hours of light daily. Indoors, especially in winter or dim spaces, boost their growth with grow lights to mimic the sun’s nurturing rays.. But for germinating, no lights are needed.

Are there any specific pests I should watch out for?

Microgreens are typically more resilient to pests than mature plants. Watch for aphids and fungus gnats. Ensure good air circulation and smart watering to keep these nuisances at bay.

What should I do if my microgreens are leggy?

Leggy microgreens signal a light deficiency. Boost their growth by moving them closer to a light source or extending their exposure time for more vibrant, robust plants.

Can I grow multiple varieties together in one tray?

While it’s possible to grow different varieties together, it’s best to choose those with similar growth rates and requirements. For example, pairing fast-growing radish microgreens with slower varieties like basil may lead to uneven growth.

My beginner experience

When I first started growing micro greens, I encountered a few bumps along the way. One of my biggest challenges was dealing with mold. You see, I was so eager to see my little seeds sprout that I tended to over-water them. I quickly learned that keeping the growing medium moist is important, but saturation can lead to mold growth, which can ruin your crop.

After researching and consulting seasoned growers, I transformed my watering routine. By misting the soil lightly each day instead of drenching it, I witnessed a remarkable transformation! My microgreens flourished, and I unlocked deeper insights into their needs.

I also discovered how fun it is to experiment with different varieties. One day, I decided to try growing radish microgreens. They sprouted quickly and added a delightful peppery flavor to my salads. It was such a rewarding experience to taste the fruits of my labor! Encouraged by that success, I ventured into growing sunflower and basil microgreens, each offering its own unique taste and texture.

These experiences taught me the value of patience and careful observation in the growing process. If you’re just starting out, don’t be discouraged by setbacks. Every challenge is an opportunity to learn and improve your technique. 

Bottom line

To cultivate vibrant microgreens, begin with top-tier seeds tailored for their growth. A sterile medium is essential to ward off mold and disease, while a warm, humid setting nurtures robust sprouts. Keep the medium moist but not soaked to prevent damping off. Supplement limited sunlight with grow lights if necessary. Track germination closely; it usually spans 2 to 7 days based on seed type. Once they sprout, place your microgreens in direct light or under grow lights for peak development. Harvest them at 1 to 3 inches tall by cutting just above the soil line for fresh flavor and nutrition.
