Troubleshooting & Problem-Solving: Common Issues in Hydroponic Microgreen Farming
Hydroponic microgreen farming is a sustainable and profitable way of growing healthy greens and vegetables. But every farming method has its problems, and there are some common problems too that can confuse new growers. Today we will talk about some such common problems and their simple solutions.
- Poor Germination (Seeds not sprouting)
Issue: If the seeds are not sprouting after sowing, the problem could be:
Low humidity
Old or low-quality seeds
Incorrect soaking time
This is Common Issues in Hydroponic Microgreen Farming
Solution:
Soak the seeds for 6–8 hours before sowing (depending on the type of seed).
Keep the tray in a dark & humid place for 2-3 days for germination (blackout method).
Always use high-quality, non-GMO seeds.
- Mold or Fungus (White fungus or smell)
Issue: If there is white fuzz or smell in the agar tray, it could be mold.
Solution:
Maintain proper air circulation (fan or open space).
Reduce watering – too much water invites mold.
Treat with neem oil spray or diluted hydrogen peroxide.
- Leggy Microgreens (Long and thin plants)
Issue: If the microgreens are long, thin and weak, it means less light exposure.
Solution:
Use a strong grow light for 12–16 hours.
Natural sunlight is also enough – just direct and proper exposure.
- Uneven Growth (not growing evenly)
Issue: Greens are growing well in some parts of the tray and weak in others.
Solution: This is Common Issues in Hydroponic Microgreen Farming
Spread the seeds evenly.
Keep the tray level right – water flow should be equal everywhere.
Rotate trays if natural light is being used.
- Yellow Leaves (Peeli patiyan)
Issue: Yellow leaves mean light deficiency or nutrient imbalance.
Solution: This is Common Issues in Hydroponic Microgreen Farming
Immediately put the tray in light after a blackout period.
If yellowing continues, use balanced hydroponic nutrients.
Bonus Tips for Smooth Hydroponic Farming:
Take care of water quality – filtered or RO water is best.
Clean trays and mats thoroughly after each batch – hygiene matters!
Maintain a farming diary – what issue came up with which seed, will be useful in future.
Conclusion
Hydroponic microgreen farming can be fun and rewarding – just a little patience and problem-solving approach is required. If you understand these common issues and fix them at the right time, then the farming journey will become even smoother and easier.🌱
