Keep germination conditions perfectly controlled with this custom-fitted humidity dome. Designed to pair seamlessly with the Sproutable 4-cell seed starting insert, this clear dome traps heat and moisture to create the ideal microclimate for fast, consistent germination. The built-in top vent lets you regulate airflow as your seedlings emerge, making it easy to gradually harden them off without removing the dome entirely. Fits both short and tall 4-cell trays. 4 cell: 5 1/8 " x 5 1/8" × 2" Show more
