What Exactly Are Microgreens (And Why Should You Grow Them)?
Before we dig in, let’s clarify what microgreens are and why they’ve become such a sensation, especially for those growing microgreens indoors year-round.
Microgreens vs. Sprouts vs. Baby Greens:
- Sprouts: These are germinated seeds grown entirely in water, usually in a jar. The entire sprout (seed, root, stem, and underdeveloped leaves) is eaten, typically within a few days.
- Microgreens: These are young vegetable greens harvested just after the cotyledon (seed leaves) have developed, and often when the first set of true leaves has emerged. They are grown in soil or a soil-like medium and are cut above the soil line, so you only eat the stem and leaves. They typically grow for 1-3 weeks.
- Baby Greens: These are a stage further along than microgreens, harvested when the plants are young and tender but have more developed true leaves (like baby spinach or baby lettuce).
Why Grow Microgreens? The Perks are Plentiful!
- Nutrient Powerhouses: Despite their small size, microgreens are packed with vitamins, minerals, and antioxidants…
- Intense Flavors & Textures: Microgreens offer a surprising array of flavors, from peppery (radish, mustard) and spicy to mild (broccoli) and nutty (sunflower)…
- Incredibly Fast Growth: This is a huge plus for impatient gardeners! You can go from seed to harvest in as little as 7-21 days…
- Minimal Space Required: You don’t need a garden, a balcony, or even much counter space… making growing microgreens indoors year-round exceptionally accessible.
- Year-Round Availability: Since you’re growing indoors, you control the environment. Fresh greens in the dead of winter? Absolutely!
- Cost-Effective: A packet of seeds can produce multiple harvests, saving you money…
- Beginner-Friendly: The process is simple, and success rates are high…
Getting Started: Everything You Need for Growing Microgreens Indoors Year-Round
Ready to start your micro-farm? Here’s what you’ll need to get your growing microgreens indoors year-round setup operational:
Choosing Your Microgreen Seeds
The variety of seeds suitable for microgreens is vast! For beginners, it’s best to start with those known for being easy and quick to germinate. Look for seeds specifically labeled for microgreen production, as they are often untreated and have high germination rates.
Easy Beginner Choices:
- Radish (Daikon, China Rose): Very fast-growing, spicy flavor.
- Broccoli: Mild, slightly earthy flavor, very nutritious.
- Pea Shoots: Sweet, crunchy, taste like fresh peas.
- Sunflower (black oil sunflower seeds): Nutty, substantial texture.
- Mustard (various types): Peppery to very spicy.
- Kale: Mild, slightly sweet.
- Cress: Peppery, fast-growing.
You can often find excellent starter kits or individual seed packets online.
Selecting Growing Trays & Containers
You don’t need fancy equipment. Shallow trays are ideal.
- Dedicated Microgreen Trays: These are often sold in sets and are a popular, durable option…
- Recycled Containers: Clamshell containers from store-bought produce (thoroughly cleaned), aluminum pie plates, or takeout containers can work well…
- Depth: Aim for trays that are 1-2 inches deep. Microgreens don’t develop extensive root systems.
Growing Medium Options
Microgreens can be grown in various mediums. For growing microgreens indoors year-round, choose one that’s clean and easy to handle.
- Potting Soil/Seed Starting Mix: A fine-textured, sterile seed starting mix or potting soil is a common choice… An organic seed starting mix is ideal…
- Coconut Coir: This is a sustainable alternative to peat moss. It has excellent water retention and aeration…
- Hydroponic Mats/Pads: These are soil-less options, often made from materials like hemp, jute, or cellulose…
Lighting Requirements
Adequate light is crucial for healthy, non-leggy microgreens.
- Sunny Windowsill: A south-facing windowsill that receives at least 4-6 hours of direct sunlight can work…
- Grow Lights: For consistent results… a grow light is highly recommended.
- Simple fluorescent shop lights (T5 or T8) can work.
- LED grow lights are more energy-efficient. Small LED grow light panel or strips can be easily mounted…
- Keep lights 2-6 inches above the microgreens.
Essential Tools
- Spray Bottle: For gently misting seeds and young seedlings.
- Watering Can (with a fine rose) or Bottom Tray: For watering more mature microgreens.
- Sharp Scissors or Knife: For harvesting.
- Labels: To keep track of what you’ve planted and when.
- Small Weight (Optional): Such as another tray or a small board, to place on top of newly sown seeds…
Step-by-Step Guide: How to Grow Microgreens Indoors
Let’s get to the fun part – sowing and growing! The process is similar for most microgreen varieties.
1. Preparing Your Seeds (If Necessary)
- Most small microgreen seeds (broccoli, mustard, cress) don’t require pre-soaking.
- Larger seeds with tough coats, like peas, sunflowers, or beets, benefit from soaking in cool water for 4-12 hours… Rinse well after soaking.
3. The Germination Phase (Blackout & Humidity)
- Blackout Period: Most microgreens benefit from a “blackout period” for the first 2-4 days…
- You can achieve this by placing another empty tray (upside down) on top of the seeded tray.
- Some growers add a small weight… on top of the covering tray…
- Humidity: During this phase, mist the seeds once or twice a day… The cover will also help maintain humidity.
4. Watering Your Microgreens
After the blackout period (when you see germination and tiny stems appearing), remove the cover and expose the seedlings to light.
- Initial Watering: Continue to mist gently for the first few days after uncovering.
- Bottom Watering: Once the microgreens are a bit more established (about an inch tall), it’s often best to switch to bottom watering…
- If using a two-tray system, add water to the bottom (solid) tray…
- If using a single tray with drainage holes, place it in a larger saucer or tray, add water to the saucer…
- Check moisture daily. The medium should remain consistently moist.
5. Providing Adequate Light
- Once uncovered, your microgreens need light – either from a sunny windowsill or a grow light.
- If using a grow light, provide 10-16 hours of light per day. A simple timer can automate this.
- Rotate your tray if using windowsill light to ensure even growth.
6. Monitoring for Growth and Potential Issues
- Watch your tiny greens grow! You’ll see rapid changes daily.
- Look out for signs of mold (see troubleshooting section). Ensure good air circulation around your trays. A small fan on low in the room can help if your space is very still.
Harvesting Your Homegrown Microgreens
This is the exciting part!
- When to Harvest: Most microgreens are ready to harvest 7-21 days after sowing… They are typically harvested when they are 1-3 inches tall…
- How to Harvest:
- Use a pair of clean, sharp scissors or a sharp knife.
- Hold a bunch of microgreens gently and cut them just above the soil line.
- Washing and Storing:
- It’s often best to wash microgreens just before use… dry them thoroughly…
- Store unwashed microgreens in a sealed container in the refrigerator…
