Here are the benefits of growing micro-greens hydroponically:
1. Grown them anywhere
2. Smaller water quantity consumption
3. Some micro-greens thrive well hydroponically
4. No soil or compost mess
5. Adequate control
To begin, one of the most important steps is to prepare your pH balanced water. The range should be around 5.5 to 6.5. You can add lime or wood ash to elevate the pH range and phosphoric acid to reduce the pH range...
If you would like to grow micro-greens commercially or on a larger scale, you will have to take advantage of the vertical set up. This means you will opt for a vertical hydroponic system that is efficient in terms of more space and greater production.
