How to Grow Microgreens
Microgreens are one of the fastest, easiest, and most rewarding crops to grow indoors, offering a full harvest in as little as one to two weeks. Whether you’re looking to add fresh, nutrient-dense greens to your meals or simply want a satisfying, low-commitment introduction to indoor growing, learning how to grow microgreens is a great place to start.
What You’ll Need
• Shallow growing trays with drainage holes
• A growing medium (soil-based mix, coconut coir, or hemp growing mats)
• Untreated, food-grade microgreen seeds
• A spray bottle or gentle watering method
• A light source (natural light or a small LED grow light)
• A humidity dome or cover for the germination stage
Step-by-Step: Growing Your First Tray of Microgreens
Step 1: Prepare your growing medium. Fill your tray with about an inch of growing medium, level and lightly compress it, then moisten it evenly without waterlogging it.
Step 2: Sow your seeds densely. Unlike traditional gardening, microgreens are sown thickly, aiming for a fairly even, dense layer of seeds across the surface of the growing medium, since you’re not growing individual plants to maturity but rather a dense mat of young sprouts.
Step 3: Cover and maintain humidity. Lightly press the seeds into the medium, then cover with a humidity dome or another tray to maintain consistent moisture during germination, which typically takes 2-4 days depending on the variety.
Step 4: Introduce light once sprouts emerge. Once you see the seeds have sprouted, remove the humidity cover and move the tray into consistent light, either a bright windowsill or under a grow light for 12-16 hours daily.
Step 5: Water consistently. Mist or bottom-water your microgreens daily, keeping the growing medium consistently moist but never waterlogged, which can lead to mold issues.
Step 6: Harvest at the right time. Most microgreens are ready to harvest once they’ve developed their first set of true leaves, typically 7-14 days after sowing, depending on the variety. Use clean scissors to cut just above the growing medium.
Choosing Your First Microgreens Varieties To Grow
Radish and broccoli microgreens are excellent first choices due to their fast germination and forgiving nature. Pea shoots and sunflower microgreens offer a satisfying crunch and slightly longer growth cycle, while arugula and mustard blends provide a bold, peppery flavor for those wanting more complexity in their harvest.
Common Mistakes to Avoid
Overwatering is the most common issue new microgreen growers encounter, leading to mold and rot before the greens even reach harvest size. Under-lighting is another frequent problem, resulting in pale, leggy sprouts rather than the vibrant, nutrient-dense greens you’re aiming for. Maintaining consistent moisture without waterlogging, and providing
adequate light once sprouts emerge, resolves the vast majority of common microgreen growing issues.
Scaling Up Once You’ve Mastered the Basics
Once you’ve successfully grown a few trays, expanding into a rotating schedule, starting new trays every few days so you have a continuous harvest, is a natural next step, along with experimenting with a wider range of varieties and flavors.
Getting the Right Equipment For Microgreens Growing
Consistent results depend on quality seeds and properly matched growing equipment. https://nordichydro.com/ offers microgreen seeds, trays, and grow lights designed to help you grow your first, and every subsequent, tray of microgreens successfully.
Growing microgreens is one of the fastest and most accessible ways to start indoor growing, with most varieties ready to harvest within two weeks. With the right seeds, consistent moisture, and adequate light, nearly anyone can successfully grow their own fresh, nutrient-dense microgreens at home.
