Setting up your first microgreens tray is a delightful endeavor that leads you down a path of sustainability and wellness, not to mention the sheer pleasure of growing your own food. But before you get your hands dirty, it’s essential to understand the essential elements you need to consider for successful microgreen cultivation.
## Choosing the Right Tray
When embarking on your microgreens journey, your primary equipment is a reliable tray. It’s recommended for beginners to start with a shallow tray (approximately 5 cm in depth). This depth provides enough room for the root systems to spread, but it doesn’t take up too much growing medium, saving both materials and money.
A tray with drainage holes is vital. Overwatering is a common mistake made by beginners, and good drainage can mediate this issue by preventing water from sitting at the bottom of the tray as it may lead to rotting roots or an outbreak of fungus.
## Selecting the Ideal Growing Medium
Once you have chosen your tray, the next step is to fill it with an optimal growing medium. There’s a variety of mediums available, but the two most common for microgreens are soil-based or soilless (such as coco coir or a peat moss blend).
The soil-based medium is a favored choice because of its excellent water retention capabilities, supply of nutrients, and compatibility with the vast majority of microgreen varieties. If you opt for soil, look for a high-quality organic potting mix.
On the other hand, soilless mediums are often fuss-free, lightweight, and great for indoor gardening where cleanliness is crucial. However, they lack inherent nutrients, so you might have to supplement your microgreens with a liquid nutrient solution if you go this route.
## Choosing Microgreen Seeds
Various seeds suitable for sprouting into microgreens are available. When starting, it’s advisable to opt for seed varieties renowned for their high germination rates and relatively easy growth process. Some popular varieties include radish, broccoli, mizuna, buckwheat, and various mustards.
Purchase untreated, high-quality seeds from reputable suppliers. Also, opt for seeds specifically packed for microgreen cultivation as they’re often tested for pathogens – essential for food safety as microgreens are typically eaten raw.
## Planting Your Microgreen Seeds
Once your tray is filled with the chosen medium, wet it with a sprayer. The idea is to get the medium moist but not soaking. Next, scatter your seeds evenly across the surface. A dense sowing will result in a lush harvest, but avoid excessive overcrowding as it can impede growth and promote mold development.
After sowing, press the seeds gently into the medium using a piece of cardboard or a clean hand to ensure they make contact with the medium. Some growers prefer to cover the seeds with a thin layer of the medium, but it’s not essential for most microgreen varieties.
## Watering and Light: Finding the Balance
Once the seeds are sown, initially cover the tray with another tray or a dark propagator lid. Creating a dark, humid environment stimulates germination. After the seeds have germinated (generally after 2-4 days), remove the cover to expose them to light.
A common query among beginners revolves around the best light for microgreens. While natural sunlight is always ideal, it’s not always attainable, particularly for indoor setups. LED grow lights are an excellent alternative, as they’re energy-efficient and perfect for producing the specific light spectrum that photosynthesizing plants require.
Watering is another critical aspect that determines the success of your microgreen tray. As a beginner, it might be challenging to strike a balance. But remember, it’s better to under-water than overwater. Microgreens prefer a moist environment — not soaking. Too much water can lead to poor growth, disease outbreaks, and negates the benefits of drainage. Use a spray or mist bottle for watering as it reduces the risk of overwatering or disrupting the tiny plants.
## Harvesting Your Microgreens
Once your microgreens have developed their first true leaves (the ones that follow the initial seed leaves), they’re ready for harvesting. This stage usually falls between 7 to 14 days after planting, depending on the variety.
To harvest, hold a clump of microgreens and use a sharp, clean pair of scissors to cut above the soil line. Immediately rinse the harvested greens in cold water, gently pat them dry, and they’re ready to enjoy.
## Bottom Line
Growing your first tray of microgreens is a gratifying experience. It does require some practice and patience, especially for beginners. But don’t be deterred if your first few attempts don’t meet your expectations. With the tips and recommendations discussed, and a little trial and error, you’ll soon be growing lush trays of nutritious microgreens in no time. Remember, growing microgreens isn’t just about the end-product; the process itself is therapeutic and enjoyable in its own right.
