When it comes to farming or gardening, one of the most important metrics of success is yield. For growers of microgreens – those tiny, nutrient-packed sprouts that have become a gourmet sensation – increasing yield can make the difference between economic survival and thriving. This article will provide a detailed guide on how to increase microgreens yield, covering optimal growing conditions, the best varieties for high yield, effective farming techniques, and more.
####
Creating Optimal Growing Conditions
Meeting the specific requirements of microgreens in terms of temperature, light, humidity, and pH levels is a key step in increasing yield. Microgreens usually prefer cool to moderate temperatures, between 18 and 23 degrees Celsius, but always check specific temperature needs for each type of microgreen. Providing an ample amount of light is essential. Fluorescent grow lights, LED lights, or natural sunlight can all be used effectively.
Growth Medium and pH Values: Microgreens tend to prefer pH levels between 5.5 and 6.5. Test your soil regularly to ensure it meets these parameters. Use a quality potting mix as your growing medium, ideally one that drains well and retains moisture at the same time. This will help maintain consistent moisture levels, another significant aspect of raising healthy, high-yield microgreens crop.
Humidity and Ventilation: High humidity can incite disease, so proper ventilation is crucial. Be sure to have airflow over your greens but avoid direct drafts.

Choosing the Right Varieties
Growing the right varieties of microgreens is another strategy to boost your yield. Some microgreens types yield more than others. Wheatgrass, sunflower, and pea shoots tend to produce a higher yield. Radishes, broccoli, and kale also produce higher numbers of greens per tray. The volume of yield per crop is important, but so is the value of each crop. For instance, certain types of microgreens may not provide as much volume per tray, but they might grow faster and command higher prices.

Effective Farming Techniques
Plant density has a significant effect on the yield of your microgreens. Packing the seeds too closely can stunt growth and lead to disease, while too sparse can lead to lower yields. The recommended seeding rate depends on the type of microgreen, but it’s generally between 10 and 12 grams per 1020 tray.
Watering is another critical factor. Overwatering can lead to mold, while under-watering can stunt growth. The best course of action usually involves using a spray bottle or mister and watering once or twice a day depending on the dryness of your environment.
####
Use a Proper Harvesting Technique
Improper harvesting can negatively impact your yield. Usually, microgreens are ready to harvest when they have developed their first set of true leaves, usually 1-2 weeks after seeding. Use a clean and sharp pair of shears or a knife to cut the stems slightly above the soil line. Be sure not to pull the roots out of the soil as this can disrupt the growth of surrounding plants.
####
Keep Observing and Learning
Continuous observation and learning are crucial. Evaluate which microgreen varieties are most prolific, identify any recurring problems like fungal disease or pest outbreaks, and analyze how your microgreens react to different light, temperature, and moisture conditions. Constantly assessing performance will help you understand what works best for your microgreens and make necessary adjustments to increase yield.
####
Utilize Continuous Planting
In continuous planting (also known as succession planting), you start a new batch of seeds every few days. This technique ensures a consistent supply of microgreens, which is especially necessary if you’re selling them. Having a continuous supply not only keeps business steady but also allows for the trial of different growing conditions and rapid implementation of learned improvements.
####
Invest In Automation
Farm automation can offer substantial yield improvements. Automated watering and lighting systems can ensure plants get the exact amounts they need, precisely when they need it. Automation can also help scale your growing operations, yielding more microgreens without proportional increases in labor.
####
Mold Prevention
Preventing mold growth is also vital as mold can significantly reduce your crop yield and lead to total crop failure. Proper plant spacing, airflow, watering techniques, and using clean trays and tools can help prevent mold growth.

Growing microgreens is a process, and like any farming endeavor, it has its challenges. However, with a careful plan, diligent care, and constant learning, you can increase your microgreens yield significantly. Good luck, and happy farming!
