Some of the most popular types of microgreens include arugula, radishes, sunflowers, and kale.

Because they are easy to grow at home using peat moss as a growth medium, microgreens offer a budget-friendly way to elevate your meals with fresh greens all year round.

Quick Growth And Harvest Time

Growing microgreens in peat moss is advantageous as it offers a quick growth and harvest time. Microgreen seeds can be planted, sprouted, and harvested within just a few weeks, making them an ideal option for those looking to grow fresh produce quickly.

The production time for microgreens can range from 7 to 21 days from seeding to harvest, depending on the growing environment. Peat moss’s high water retention properties allow for consistent moisture levels throughout the germination phase, promoting faster seedling growth and earlier harvesting times.

Hydroponic Systems For Growing Microgreens

Hydroponics is a popular soilless cultivation method used to grow microgreens. It involves growing plants in a nutrient solution instead of soil. Hydroponic systems can provide various benefits, such as more efficient use of water, faster growth rates, and reduced need for pesticides.

One example of a hydroponic system suitable for growing microgreens is the deep-water culture (DWC) system. In this type of setup, plants are suspended in net pots over a reservoir filled with nutrient-rich water.

Another popular hydroponic system for growing microgreens is aeroponics. This method uses a misting mechanism to deliver nutrients directly to plant roots and provide them with ample oxygenation through constant airflow.

Regardless of which hydroponic system you decide on, it’s important to keep an eye on factors like pH levels, nutrient balances, and airflow quality throughout your plant’s life cycle to ensure optimal growth conditions at all stages.

Common Problems And Solutions In Growing Microgreens In Peat Moss

If you encounter problems such as underwatering, overwatering, poor germination, or mold/fungus growth when growing microgreens in peat moss, solutions can include adjusting watering schedules and drainage, using a sterilized seed-starting mix, increasing ventilation and air circulation in the grow room.

Underwatering Or Overwatering

One of the most common problems in growing microgreens is either overwatering or underwatering them. Overwatering can cause root problems, mold growth, and, ultimately, death for the plants.

On the other hand, underwatering can lead to stunted growth and poor microgreen quality.

To prevent overwatering, it’s best not to completely soak the soil when watering your microgreens. Using a spray bottle or watering from the bottom up may be beneficial in preventing excess water from sitting on top of the soil for too long.

However, it’s still important to ensure that your microgreens get enough water so they don’t dry out completely.

Poor Germination

Getting a good germination rate is crucial for growing healthy microgreens. However, poor germination is a common problem when growing microgreens in peat moss. The most common cause of seed starting failure is damping off, a fungal disease that attacks the plant’s stem at the soil level and causes it to weaken and collapse.

To prevent damping off, cover the mixture with peat moss after sowing seeds and use a sterile, soil-less mixture. Another solution is to mist rather than pour water on top of the seeds to avoid overwatering them.

Additionally, make sure to keep humidity levels high during the vegetative stage by using proper ventilation or a humidifier.

Mold Or Fungus Growth

Mold growth on microgreens is a common problem faced by growers, but it can be prevented through proper environmental conditions and seed selection. Excessive watering or moisture, high humidity, poor air circulation, and contaminated seeds are common reasons for mold growth on microgreens in peat moss.

To prevent mold growth, ensure that the environment has adequate ventilation and lower humidity levels with a humidifier or dehumidifier if necessary. It’s also crucial to use clean water to avoid contamination from bacteria and other microbes.

Harvesting And Storing Microgreens

To harvest microgreens, use a pair of scissors to cut the stems just above the soil surface once they have reached 1-3 inches in height; then, rinse and dry them before storing them in an airtight container or plastic bag with a paper towel to absorb excess moisture.

Proper Harvesting Techniques

Harvesting microgreens at the optimum time ensures that they are fresh and have their full flavor and nutritional value intact. Here are some tips for proper harvesting:

  1. Use sharp scissors to cut the microgreens just above their soil line.
  2. Harvest when the first true leaves have developed, usually around 10-14 days after planting.
  3. Make sure to harvest before the microgreens reach their growth – limiting factors, such as overcrowding or yellowing leaves.
  4. Harvest in the morning or evening when the plants are not stressed from heat or strong sunlight.
  5. Clean and sanitize your tools before and after use to prevent contamination.
  6. Store freshly harvested microgreens in a cool place with high humidity, such as a refrigerator, for up to one week.
  7. Avoid washing microgreens, as they are delicate and can become damaged easily.

Remember that harvesting is an essential part of growing microgreens and should be done with care to maximize their flavor and nutrition.

Storage Recommendations

After harvesting your microgreens, it’s important to store them properly to maintain their freshness and flavor. The best way to do this is by keeping them growing right in the tray and harvesting as needed.

If this isn’t possible, you can store harvested microgreens in airtight containers in the refrigerator for up two weeks. It’s important to avoid watering microgreens 24-48 hours before harvesting to ensure they are completely dry.

Increasing the shelf life of harvested microgreens by just a couple of days will reduce the number of trays needed to grow over the year, saving you time, money, and energy.

Tips For Maximum Freshness

Proper storage is crucial for maximizing the freshness and shelf life of microgreens. To increase their shelf life, it’s recommended to keep the outside of the microgreens dry.

One effective way to do this is by using a salad spinner or gently patting them with paper towels. Research suggests that storing microgreens in dark storage at 41°F can increase their shelf life by up to 10-14 days.

Proper harvesting techniques are also essential for optimizing the quality of your microgreens. Be sure to harvest with a clean, straight cut for maximum freshness and flavor.
