What You’ll Need
Before we dive in, let’s gather our supplies. The beauty of this method is that you probably already have most of these items lying around!
* Seeds: Choose your favorite microgreen seeds! Popular options include broccoli, radish, sunflower, pea shoots, and kale. Make sure you’re using seeds specifically intended for sprouting or microgreens, not treated seeds meant for full-grown plants.
* Growing Trays: You’ll need two trays – one with drainage holes (the inner tray) and one without (the outer tray). These can be plastic seedling trays, repurposed food containers (like takeout containers), or even baking dishes. Just make sure the inner tray fits snugly inside the outer tray.
* Growing Medium: Instead of soil, we’ll be using a non-soil medium. Great options include:
* Hemp Mats: These are my personal favorite! They’re absorbent, sustainable, and provide excellent support for the roots.
* Coconut Coir Mats: Similar to hemp mats, coconut coir is another eco-friendly and effective option.
* Paper Towels: A readily available and budget-friendly choice. Use unbleached paper towels for best results.
* Burlap: A natural and breathable option, but it might require a bit more attention to moisture levels.
* Spray Bottle: For misting the seeds and keeping the growing medium moist.
* Weight (Optional): A small weight, like a book or a brick wrapped in plastic, to help the seeds germinate evenly.
* Dark Cover (Optional): A lid or another tray to block out light during the germination phase.
* Hydrogen Peroxide (3%): This is optional, but a diluted solution can help prevent mold growth.
* Measuring Cup: For measuring water.
* Clean Water: Tap water is usually fine, but filtered water is even better.
Step-by-Step Instructions: Soil-Free Microgreen Magic
Okay, let’s get our hands dirty (well, not really, since we’re avoiding soil!). Follow these steps, and you’ll be enjoying your own homegrown microgreens in no time.
Phase 1: Preparing the Growing Medium and Seeds
1. Soak the Seeds (Optional but Recommended): Soaking your seeds before planting can significantly improve germination rates. Place your seeds in a bowl and cover them with water. The soaking time varies depending on the seed type:
* Broccoli, radish, kale: 4-6 hours
* Sunflower: 8-12 hours
* Pea shoots: 12-24 hours
This step helps to soften the seed coat and kickstart the germination process.
2. Prepare the Growing Medium:
* Hemp or Coconut Coir Mats: Cut the mat to fit snugly inside your inner tray. Thoroughly wet the mat with water and gently squeeze out any excess. It should be damp but not dripping.
* Paper Towels: Line the inner tray with 3-4 layers of paper towels. Moisten the paper towels thoroughly with water, ensuring they are evenly saturated. Gently press down to remove any air pockets.
* Burlap: Cut the burlap to fit the inner tray. Soak it in water until fully saturated, then gently squeeze out the excess water.
3. Sow the Seeds: Sprinkle the soaked seeds evenly over the prepared growing medium. Don’t overcrowd them! You want them close enough to support each other but not so dense that they compete for resources. A good rule of thumb is to aim for about 75% coverage of the growing medium.
4. Mist the Seeds: Gently mist the seeds with water from your spray bottle. This will help them adhere to the growing medium and stay hydrated.
5. Optional: Hydrogen Peroxide Treatment: If you’re concerned about mold, you can lightly mist the seeds with a diluted hydrogen peroxide solution (1 tablespoon of 3% hydrogen peroxide per cup of water). This can help inhibit mold growth without harming the seeds.
Phase 2: Germination (The Dark Phase)
1. Cover the Seeds: Place the dark cover (lid or another tray) over the inner tray to block out light. This creates a humid environment that encourages germination.
2. Weight the Seeds (Optional): Place a light weight on top of the cover. This helps the seeds make good contact with the growing medium and promotes even germination. Be careful not to use anything too heavy, as it could crush the seeds.
3. Maintain Moisture: Check the moisture level of the growing medium daily. Gently mist the seeds with water as needed to keep them consistently damp. You don’t want them to dry out, but you also don’t want them to be soaking wet.
4. Wait for Germination: Depending on the seed type, germination typically takes 2-4 days. You’ll know the seeds have germinated when you see tiny sprouts emerging.
Phase 3: The Light Phase (Greening Up)
1. Remove the Cover and Weight: Once the seeds have germinated, remove the dark cover and the weight (if you used one).
2. Introduce Light: Now it’s time for the microgreens to see the light! Place the tray in a well-lit area, such as a windowsill or under a grow light. Avoid direct sunlight, which can scorch the delicate seedlings.
3. Water from the Bottom: This is a crucial step to prevent mold and mildew. Pour water into the outer tray, allowing the growing medium to absorb moisture from the bottom. This encourages the roots to grow downwards and keeps the leaves dry.
4. Maintain Moisture: Continue to water from the bottom as needed, keeping the growing medium consistently damp. Check the moisture level daily and adjust your watering schedule accordingly.
5. Rotate the Tray: If you’re using a windowsill, rotate the tray daily to ensure that the microgreens receive even light exposure. This will prevent them from leaning towards the light source and becoming leggy.
Phase 4: Harvesting and Enjoying Your Microgreens
1. Harvest Time: Your microgreens are ready to harvest when they have developed their first set of true leaves (the second set of leaves after the initial seed leaves). This usually takes 7-14 days, depending on the seed type.
2. Harvesting Technique: Use clean scissors or a sharp knife to cut the microgreens just above the growing medium.
3. Rinse and Dry: Gently rinse the harvested microgreens with cool water to remove any debris. Pat them dry with a paper towel or use a salad spinner to remove excess moisture.
4. Storage: Store the harvested microgreens in an airtight container in the refrigerator. They will typically last for 5-7 days.
5. Enjoy! Now for the best part – enjoying your homegrown microgreens! Add them to salads, sandwiches, smoothies, soups, or use them as a garnish for your favorite dishes. They’re packed with nutrients and add a delicious burst of flavor to any meal.
Troubleshooting Tips
* Mold Growth: If you notice mold growing on your microgreens, it’s usually a sign of overwatering or poor air circulation. Remove the affected areas and improve ventilation by placing a small fan near the tray. You can also try misting with a diluted hydrogen peroxide solution.
* Leggy Microgreens: Leggy microgreens are a sign of insufficient light. Move the tray to a brighter location or supplement with a grow light.
* Uneven Germination: Uneven germination can be caused by inconsistent moisture levels or uneven seed distribution. Make sure to keep the growing medium consistently damp and spread the seeds evenly.
* Slow Growth: Slow growth can be caused by a variety of factors, including low temperatures, insufficient light, or poor seed quality. Make sure the tray is in a warm, well-lit location and use high-quality seeds.
Seed Specific Tips
* Sunflower Seeds: These benefit greatly from a longer soaking period (12-24 hours). They also tend to have a thicker seed coat, so a little extra weight during germination can be helpful.
* Pea Shoots: Pea shoots also require a longer soaking period (12-24 hours). They can be a bit more prone to mold, so good air circulation is essential.
* Radish Seeds: Radish seeds germinate quickly and are
