Use light after the seed has woken up
Seeds need moisture first. Once shoots emerge, light helps the blades green up and keeps growth from stretching pale and weak.
Humidity domes need venting
Domes can steady moisture during germination, but sealed humidity can turn stale. Vent the tray once sprouts emerge and avoid trapping warmth around wet seed.
Small trays are useful for testing seed and timing
A multi-tray starter is helpful for testing soak times, rotating small batches, and learning how your room affects moisture and airflow.
Buying questions
Quick answers before checkout.
Do I need a grow light for wheatgrass?
Not always. Bright indirect window light can work. A grow light helps when natural light is weak or inconsistent.
Can a seed starter tray grow cat grass?
Yes, as long as the tray is clean, the seed layer is not too thick, and the grass is offered fresh.
Should the humidity dome stay closed?
No. Vent or remove the dome once sprouts emerge so the tray does not become stale and overly humid.
