What You’ll Need: The Essentials
Before we dive in, let’s gather our supplies. Don’t worry, most of these are readily available and won’t break the bank.
* Growing Trays: You’ll need two trays – one with drainage holes (the inner tray) and one without (the outer tray or reservoir). I prefer standard 10×20 inch trays, but you can adjust the size based on your needs.
* Growing Medium: This is where the “soil-free” magic happens! We’ll be using hydroponic grow mats. I recommend coco coir mats or hemp mats. They’re absorbent, sustainable, and provide excellent support for the roots.
* Microgreen Seeds: Choose your favorite varieties! Radish, broccoli, sunflower, pea shoots, and kale are all great options for beginners. Make sure you’re buying seeds specifically intended for microgreens, as they’re often untreated.
* Spray Bottle: A simple spray bottle is essential for keeping the seeds and mats moist during germination.
* Water: Filtered water is best, but tap water that’s been left to sit for 24 hours to allow chlorine to dissipate will also work.
* Weight (Optional): A small weight, like a book or a brick wrapped in plastic, can help with even germination.
* Light Source (Optional): While microgreens can grow indoors with indirect sunlight, a grow light will significantly improve their growth and color. A simple LED shop light works wonders.
* Hydrogen Peroxide (3%): This is optional, but I like to add a small amount to the water to help prevent mold and fungal growth.
Step-by-Step Instructions: Building Your Soil-Free Microgreens Garden
Okay, let’s get our hands dirty (well, not really, since it’s soil-free!). Follow these steps carefully, and you’ll be harvesting delicious microgreens in no time.
1. Prepare the Growing Trays:
* Make sure your growing trays are clean. Wash them with soap and water, and rinse thoroughly. This helps prevent any unwanted bacteria or mold from affecting your microgreens.
* Place the tray with drainage holes (the inner tray) inside the tray without drainage holes (the outer tray). This creates a reservoir for the water.
2. Soak the Growing Medium:
* This is a crucial step! Your chosen grow mat needs to be thoroughly saturated with water before you sow the seeds.
* Place the grow mat in a clean container or sink.
* Pour water over the mat until it’s completely submerged.
* Let it soak for at least 15-20 minutes, or until it’s fully expanded and saturated.
* Gently squeeze out any excess water. The mat should be damp but not dripping.
3. Place the Grow Mat in the Tray:
* Carefully place the soaked grow mat into the inner tray.
* Make sure it fits snugly and covers the entire bottom of the tray. You might need to trim it slightly with scissors if it’s too large.
4. Sow the Microgreen Seeds:
* This is where the magic begins! Evenly distribute the microgreen seeds over the surface of the grow mat.
* The key is to avoid overcrowding. Too many seeds can lead to poor air circulation and increase the risk of mold.
* Refer to the seed packet for recommended seeding density. As a general rule, aim for a single layer of seeds, with a little space between them.
* For smaller seeds like radish or broccoli, you can use a shaker or a spoon to help distribute them evenly.
* For larger seeds like sunflower or pea shoots, you can gently press them into the mat to ensure good contact.
5. Water the Seeds:
* Gently mist the seeds with water using your spray bottle.
* The goal is to moisten the seeds without dislodging them.
* Make sure the entire surface is evenly moistened.
6. Weighting (Optional but Recommended):
* Applying a light weight to the seeds during the first few days of germination can help improve germination rates and create more uniform growth.
* Place a piece of cardboard or another tray on top of the seeds.
* Place a light weight on top of the cardboard or tray. A book or a brick wrapped in plastic works well.
* Make sure the weight is evenly distributed and not too heavy, as this could crush the seeds.
7. Dark Period (Crucial for Germination):
* Microgreens germinate best in the dark. This encourages them to stretch and reach for light, resulting in taller, more robust seedlings.
* Place the tray in a dark location, such as a closet, a cupboard, or under a table.
* Maintain darkness for 2-3 days, or until the seeds have germinated and started to sprout.
8. Monitor Moisture Levels:
* During the dark period, it’s important to monitor the moisture levels of the grow mat.
* Use your spray bottle to mist the seeds and mat as needed to keep them consistently moist.
* Avoid overwatering, as this can lead to mold and fungal growth.
Post-Germination Care: Bringing Your Microgreens to Life
Once your seeds have germinated and started to sprout, it’s time to move them into the light and watch them grow!
1. Introduce Light:
* After the dark period, remove the weight and move the tray to a location with bright, indirect sunlight or under a grow light.
* If using a grow light, position it about 6-12 inches above the tray.
* Provide 12-16 hours of light per day for optimal growth.
2. Watering:
* Continue to monitor the moisture levels of the grow mat.
* Water the microgreens as needed to keep the mat consistently moist.
* Instead of misting, you can now add water directly to the outer tray (the reservoir). The grow mat will wick up the water as needed.
* Avoid overwatering, as this can lead to root rot and other problems.
* I like to add a small amount of 3% hydrogen peroxide (about 1 teaspoon per quart of water) to the reservoir to help prevent mold and fungal growth.
3. Air Circulation:
* Good air circulation is essential for preventing mold and fungal growth.
* Make sure the growing area is well-ventilated.
* You can use a small fan to gently circulate the air around the microgreens.
4. Monitoring for Mold:
* Keep a close eye on your microgreens for any signs of mold or fungal growth.
* Mold typically appears as white or gray fuzzy patches on the seeds, stems, or leaves.
* If you spot any mold, remove the affected areas immediately.
* Improve air circulation and reduce humidity to prevent further mold growth.
* If the mold is widespread, it’s best to discard the entire batch and start over.
Harvesting Your Soil-Free Microgreens: Time to Enjoy!
The best part! 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 about 7-14 days, depending on the variety.
1. Harvesting:
* Use clean scissors or a sharp knife to cut the microgreens just above the grow mat.
* Harvest only what you need, and leave the rest to continue growing.
2. Washing:
* Gently wash the harvested microgreens in cool water to remove any debris.
3. Storing:
* Pat the microgreens dry with a paper towel.
* Store them in a sealed container in the refrigerator for up to a week.
Troubleshooting: Common Issues and Solutions
Even with the best care, you might encounter a few challenges along the way. Here are some common issues and how to address them:
* Poor Germination:
* Possible causes: Old seeds, improper watering, temperature fluctuations.
* Solutions: Use fresh seeds, ensure consistent moisture levels, maintain a stable temperature.
* Mold Growth:
* Possible causes: Overwatering, poor air circulation,
