🌱 How to Grow Swiss Chard Microgreens Hydroponically

✅ Best Hydroponic System: Grow Tray with Capillary Mat (Passive Wick System)

This system uses a water reservoir, a capillary mat, and a growing tray. It’s soil-free, easy to maintain, and perfect for short-cycle crops like microgreens.

🧰 Materials List

Item Description
1. Growing Tray (with holes) A 10″ x 20″ mesh tray or slotted microgreen tray
2. Reservoir Tray (without holes) Same size as the growing tray to hold water
3. Capillary Mat Felt mat that wicks water from reservoir into the grow medium
4. Growing Medium Coconut coir, hemp mat, or hydroponic microgreen grow mat
5. Swiss Chard Seeds Organic microgreen seeds (e.g., Rainbow, Ruby Red)
6. pH-balanced Water Adjusted to ~6.0 using pH Up/Down solution
7. Spray Bottle For misting seeds during germination
8. pH Test Kit Drops or digital pen to test your water
9. Grow Light (Full Spectrum LED) 12–16 hours/day if growing indoors
10. Humidity Dome (optional) Helps retain moisture during germination
11. Small Fan (optional) Promotes air circulation to prevent mold

📋 Step-by-Step Instructions

🌾 1. Prepare the Reservoir System

  • Fill your bottom tray (no holes) with about ½ inch (1–1.5 cm) of water.

  • Lay a capillary mat across the bottom so it touches the water.

  • Place the grow mat or coco coir on top of the capillary mat inside the upper tray (with holes).

🌿 2. Pre-Treat Seeds (Optional but Helpful)

  • Soak Swiss chard microgreen seeds in room temperature water for 4–6 hours to improve germination.

  • Drain and lightly pat dry before sowing.

🌱 3. Sow the Seeds

  • Evenly spread seeds across the surface of the grow medium.

    • Use about 1–1.5 tablespoons of seed per 10″x20″ tray.

  • Press seeds lightly into the medium to ensure contact.

💧 4. Mist & Cover

  • Mist the tray generously with a spray bottle of pH-balanced water.

  • Cover the tray with a humidity dome or blackout lid to simulate darkness and encourage even germination.

  • Place in a warm, dark area for 2–3 days.

☀️ 5. Provide Light After Germination

  • Once seeds sprout and push against the cover (usually day 3–4), remove the lid and place under a grow light.

    • Keep light 1–2 inches above the greens.

    • Light cycle: 12–16 hours per day.

  • Ensure the capillary mat stays moist by topping off the reservoir as needed.

🌬 6. Promote Airflow

  • Add a small fan nearby (not directly blowing) to reduce humidity and prevent mold.

  • Mist lightly if the surface feels dry, but don’t oversaturate.

✂️ 7. Harvest

  • Ready for harvest in 10–15 days, once the first true leaves emerge.

  • Use clean scissors to cut just above the medium.

  • Rinse, pat dry, and store in the fridge for up to 5 days.

📌 Quick Tips for Success

  • Ideal Temp: 65–75°F (18–24°C)

  • Humidity (Germination): 60–70%

  • pH of Water: 5.8–6.2

  • Avoid overwatering—damp, not soggy

  • Sanitize trays between crops to avoid mold and bacteria

💡 Bonus: Why the Capillary Mat System?

This method:

  • Requires no pumps or electricity

  • Keeps water consistent and reduces risk of root rot

  • Is beginner-friendly and cost-effective

Harvesting and Using Swiss Chard Microgreens

Harvesting Time

The ideal time to harvest hydroponic Swiss chard microgreens is when the first true leaves emerge, typically around 10-15 days after sowing. At this stage, the microgreens exhibit vibrant coloration, tender textures, and concentrated flavors, signifying their readiness for harvest. Gently snipping the stems just above the growth medium allows for convenient and efficient harvesting.

Culinary Uses

Once harvested, hydroponic Swiss chard microgreens offer a delightful culinary experience with their mild, earthy flavors and crisp textures. These nutrient-dense microgreens are perfect for enhancing salads, sandwiches, smoothies, and various culinary creations. Their versatility makes them a prized ingredient, adding a vibrant touch and nutritional boost to a wide range of dishes.
