Step-by-Step Guide

Here’s a step-by-step guide to help you set up your hydroponic mustard green garden. We focus on a Deep Water Culture (DWC) system, as it’s one of the simplest systems for leafy greens. However, we also include tips for setting up an Nutrient Film Technique (NFT) system as well.

 Assemble the System Frame

For DWC System

  • Choose your container/reservoir

Use a large opaque plastic container that can hold water and nutrient solution. A lid with holes cut for net pots is ideal.

  • Drill holes for net pots

Use a hole saw to drill holes in the container lid that fit the size of your net pots. Make sure the pots sit securely without falling through.

  • Prepare air pump and air stones

Place air stones at the bottom of the water reservoir. Connect them to the air pump using tubing. The air stones should cover most of the reservoir’s base to ensure even oxygenation.

  • Fill the reservoir with water

Fill the container with water to about two inches below the net pots (once they are inserted). Make sure to use dechlorinated water.

For NFT System

  • Set up the channel system

Position your PVC pipes at a slight incline. Drill holes for net pots along the top of the pipes. The pipes should slope slightly to allow the water to flow back to the reservoir.

  • Install the water pump and tubing

Place the water pump in the reservoir. Connect tubing to carry water to the highest point of the inclined PVC pipes. Install a drain system at the lowest point to return water to the reservoir.

  • Fill the reservoir with water

Similar to the DWC system, fill the water reservoir, making sure the water pump can circulate water through the PVC pipes.

 Prepare the Growing Medium and Seeds

Soak the growing medium

  • Soak your chosen growing medium (Rockwool, clay pellets, etc.) in water to saturate it.

Plant the mustard green seeds

  • Place 2–3 mustard green seeds in each growing medium cube or pellet. You can germinate them in a seedling tray or directly in the net pots.

Use a humidity dome (optional)

  • If using a seedling tray, cover it with a humidity dome to help with germination. Keep the tray in a warm place with plenty of light until the seeds sprout (5–7 days).

Transplant seedlings into net pots

  • Once seedlings have a good root system (2–3 inches long), carefully place them into the net pots filled with the growing medium.

 Set Up the Nutrient Solution

Mix the nutrient solution

  • Follow the manufacturer’s instructions for mixing hydroponic nutrients for leafy greens. Add the solution to your water in the reservoir.

Check pH and EC levels

  • Use your pH meter to ensure the water’s pH is between 5.5–6.5. Adjust using pH Up or pH Down if necessary.
  • Use the EC meter to measure nutrient concentration and ensure it’s within the recommended range for mustard greens (typically 1.2–1.6 mS/cm).

Assemble the Lighting System

Position grow lights

  • Place full-spectrum LED grow lights above the plants, about 12–18 inches above the seedlings. As the plants grow, raise the lights to avoid light burn but keep them close enough for optimal growth.

Set up a timer

  • Set a timer for 14–16 hours of light per day. Mustard greens require good light exposure to grow healthy and quickly.

 Begin Growing and Monitoring

Install the air pump (DWC)

  • Turn on the air pump to start oxygenating the water. Ensure bubbles are rising evenly across the reservoir.

Start the water pump (NFT)

  • Turn on the water pump, ensuring the nutrient solution is circulating through the PVC pipes and back into the reservoir.

Monitor the plants

  • Regularly check for nutrient deficiencies, root health, and water levels. Top off the water as needed and replenish nutrients every 1–2 weeks.

Check pH and EC regularly

  • Measure the pH and EC levels every few days and adjust as necessary to maintain optimal growing conditions.

 Care and Maintenance

Change nutrient solution

  • Change the nutrient solution completely every 1–2 weeks to prevent salt buildup and nutrient imbalances.

Prune and thin plants

  • If your mustard greens become overcrowded, thin out the weaker plants to give the stronger ones more room to grow.

Monitor for pests and diseases

  • Although hydroponic systems have fewer pest problems, check your plants regularly for signs of mold or pests.

Harvesting Mustard Greens

Harvest when leaves are mature

  • You can start harvesting mustard greens when the leaves reach 4–6 inches long. Use scissors or a sharp knife to cut the leaves at the base.

Regrow or restart

  • After harvesting, the plants may continue to produce more leaves. You can keep harvesting for several weeks before needing to replant new seeds.

By following these steps, you’ll have a functional hydroponic system to grow your mustard greens. Let me know if you need more details on any specific step or have questions about system design!

Harvesting and Storage

Optimal Harvest Time

The optimal time to harvest hydroponic mustard microgreens is when they are 7 to 14 days old, typically after they’ve developed their first set of true leaves (the second set of leaves after the initial seed leaves or cotyledons). At this stage, the microgreens are at their peak in terms of flavor and nutrient content. The plants should be around 2 to 3 inches tall, with vibrant green leaves and sturdy stems. Harvesting at this point ensures the best taste—slightly spicy and crisp—while also preserving their nutritional value, which includes vitamins A, C, and K.

Proper Storage Techniques

To properly store hydroponic mustard microgreens, first, gently rinse them in cool water and thoroughly dry them using a salad spinner or by patting them with a paper towel. Any excess moisture can lead to spoilage. Once dry, place the microgreens in a breathable container or a resealable plastic bag lined with a dry paper towel to absorb moisture. Store them in the refrigerator at a temperature between 35-40°F. For best freshness and flavor, use them within 5-7 days. Avoid crushing them in the fridge by keeping them in a dedicated space to prevent wilting.

Conclusion

In conclusion, hydroponic mustard microgreens offer a wealth of benefits, from their exceptional nutritional value to their streamlined growing process and versatile usage in culinary applications. Embracing hydroponic soilless agriculture for cultivating mustard microgreens presents an opportunity to experience the joys of cultivating fresh, vibrant greens in a controlled and sustainable manner.
