How to Grow Onions Hydroponically: A Simple Guide
Are you curious about growing onions without soil? Hydroponics is a fantastic way to grow fresh, flavorful onions right at home! Hereβs a step-by-step guide for beginners to get started.
Growing medium (like coco coir or perlite)
Net pots and a growing tray
Light source (2000 lumens per square meter)
Set up your hydroponic system with net pots and a growing tray. Fill the net pots with your chosen medium.
Add water and nutrients. Keep the water pH between 6 and 7 for the best growth.
Plant the onion sets or seeds in the medium, ensuring theyβre securely placed.
Onions love light, so aim for about 12-16 hours of light daily, with a temperature around 18-24Β°C. You can use grow lights if needed.
Green onions: Ready in 3-4 weeks
Bulb onions: Takes about 90 days
Hydroponic onions are low-maintenance, quick to grow, and donβt need much space. Happy gardening!
