Use bottom watering for stronger roots

Fill the bottom tray (no holes) with about 1 cm of water and let the growing tray wick moisture up through the drainage holes. Bottom watering encourages roots to grow downward, produces sturdier stems, and keeps the leaf surface dry — reducing mold risk.

How to Do It

1. Lift the growing tray and pour water into the solid tray beneath it
2. Set the growing tray back down and let it absorb for 10-15 minutes
3. Drain any standing water that remains after 15 minutes
4. Repeat once or twice daily depending on how fast the medium dries

Tips

• Check moisture by lifting the tray — a light tray needs water
• Mist from the top only during the first 2-3 days before roots establish
• Overwatering is the #1 killer of microgreens — soggy medium breeds mold
