1010 Extra-Strength Vented Humidity Domes

Humidity Control for Small-Batch Seed Starting

A durable humidity dome designed to support consistent germination in 1010 tray setups.

The 1010 Extra-Strength Vented Humidity Dome helps regulate moisture and temperature during the most critical stage of growth—seed germination. Designed to fit both 1010 deep and 1010 shallow trays, this dome creates a stable environment for seedlings and microgreens without sealing in stagnant air.

Made from extra-strength, food-grade recycled plastic, it’s built for repeated use and pairs well with heat mats for improved germination consistency.
