How to Grow Hydroponic Arugula Microgreens

Growing hydroponic arugula microgreens is a simple and rewarding process. Here is a step-by-step guide, including a detailed list of materials and instructions to ensure a successful harvest.

Materials Needed

1. Arugula Microgreen Seeds

Make sure to buy seeds specifically labeled for microgreens, as they germinate faster and grow better in a dense setup.

2. Growing Tray (with or without drainage holes)

Preferably a shallow tray, about 1–2 inches deep. You can use one with holes for drainage or without (since this is a hydroponic system, either option works with adjustments).

3. Grow Mat or Growing Medium

Hemp or coconut coir mats are ideal for hydroponic systems. These will provide a stable base for the seeds to grow.

4. pH-Balanced Water (pH 5.5–6.5)

Use either distilled water or pH-balanced water with added nutrients for hydroponics (optional). pH meters or strips can be used to ensure the proper range.

5. Nutrient Solution (optional)

If you want to boost growth, a mild liquid hydroponic nutrient mix can be added to the water.

6. Misting Bottle

For gentle watering without disturbing the seeds.

7. Humidity Dome (optional but recommended)

A plastic dome or even a plastic bag to retain moisture during germination.

8. LED Grow Light (if not enough natural light)

A full-spectrum grow light is recommended if you don’t have access to at least 4–6 hours of direct sunlight per day.

9. pH Meter or Test Strips

To ensure your water is within the optimal pH range.

10. Paper Towels (optional)

To help with even moisture distribution.

Instructions

1. Prepare the Tray

Place the grow mat (such as hemp or coconut coir) inside the tray. If using a tray without drainage holes, ensure the grow mat is properly moistened, but not soaking wet. If using a tray with drainage holes, ensure you have a second tray underneath to catch excess water.
Dampen the mat with pH-balanced water. You can use a misting bottle to gently spray water across the mat until it’s evenly moist.

2. Prepare the Seeds

Arugula seeds are small and don’t require pre-soaking. Measure out your seeds according to the size of your tray. A standard 10×20 inch tray typically uses about 1–2 tablespoons of arugula seeds.

3. Sow the Seeds

Evenly scatter the seeds over the surface of the moist grow mat. Try to distribute them as evenly as possible to avoid overcrowding in certain areas. You want the seeds to be spread out but still close together.

4. Initial Watering and Covering

Lightly mist the seeds with water, ensuring they are moist but not drenched. Cover the tray with a humidity dome, or place a plastic bag over the tray to retain moisture.
If you don’t have a humidity dome, simply place the tray in a dark area to encourage germination.

5. Germination (2–3 Days)

Place the tray in a dark location or keep it covered with the humidity dome for 2–3 days until the seeds germinate. During this time, check daily to ensure the grow mat stays moist. Mist with water if necessary.

6. Uncover and Provide Light

Once the seeds have germinated and small shoots (called cotyledons) appear (usually around day 3), remove the humidity dome and expose the tray to light.
If using natural sunlight, ensure the microgreens get 4–6 hours of direct light each day. Otherwise, place an LED grow light about 6–12 inches above the tray for 12–16 hours a day to promote healthy growth.

7. Ongoing Care

Continue to mist the microgreens with water 1–2 times per day to keep them hydrated, but avoid overwatering. Ensure the growing mat stays moist but not waterlogged.
If using a nutrient solution, you can mix a very mild hydroponic nutrient formula into the water after germination. Follow the instructions on your nutrient mix for dilution ratios (arugula doesn’t need much, so keep it light).

8. Monitor Growth

Arugula microgreens grow quickly and should be ready for harvest within 7–14 days. You’ll notice they grow their first set of leaves (cotyledons) initially, followed by their true leaves, which have the characteristic peppery flavor.

9. Harvesting

When the arugula microgreens reach 2–3 inches in height and have their first true leaves, they’re ready to harvest. Use clean, sharp scissors to snip the microgreens just above the mat.

10. Storing

Rinse the harvested microgreens under cool water, pat them dry, and store them in an airtight container in the refrigerator for up to a week. Fresh arugula microgreens are best when used immediately to preserve their nutritional content and flavor.

Additional Tips

Lighting: Consistent light after germination is key to growing healthy, robust microgreens. If you’re using artificial lights, ensure they are on for at least 12–16 hours daily.
Air Circulation: If growing in a humid environment, ensure proper ventilation to avoid mold growth on the grow mat or seeds.
Nutrient Solution: Arugula microgreens can grow without added nutrients, but you may see faster, more robust growth with a weak nutrient solution.

This setup provides you with fresh, spicy arugula microgreens quickly and efficiently with little space or effort.

Harvesting and Consumption

Harvesting arugula microgreens is a meticulous process that requires precision and timing to achieve the best flavor, texture, and nutritional content. It involves several key techniques that ensure the highest quality and freshness of the arugula microgreens.

Here are the essential harvesting techniques for arugula microgreens:

Timing: Determine the optimal time for harvesting arugula microgreens, which is typically when the first true leaves begin to develop.
Cutting: Use sterilized scissors or a sharp knife to cut the microgreens just above the soil line, ensuring a clean and precise cut.
Rinsing and Drying: Gently rinse the harvested microgreens with cold water, then pat them dry with paper towels to remove excess moisture.
Storage: Store the harvested arugula microgreens in a breathable container lined with a paper towel to maintain their freshness and crispness.

Understanding and implementing these harvesting techniques is crucial to achieving an enriching experience for both growers and consumers alike. Practicing these methods will result in arugula microgreens that are bursting with flavor and packed with essential nutrients, making them a delightful addition to any dish.
