Tall greenhouse humidity dome with adjustable side vents — the cloche cover that turns any seedling tray into a mini sanctuary. Locks in warmth and moisture during germination, vents open as seedlings grow up to the lid.

Why we picked it

  • Best for: Germinating finicky seeds, hardening off seedlings, propagating cuttings
  • Size: 11" × 21" × 7" tall — fits standard 1020 seed tray
  • Material: Clear UV-stable polypropylene with twist-open vents
  • Difficulty: ●●○○○ Cover, water, adjust vents
  • Personality: The Sanctuary Maker

How to use

Place over a seed tray after sowing. Keep vents closed during germination (90%+ humidity). Once 80% of seedlings are up, crack vents open for airflow. Remove fully when seedlings nearly touch the top to prevent leggy growth.
