RooTrimmer 6.3-Inch Tall Humidity Domes - 10 Pack for 1020 Trays | Extra Strength BPA-Free Clear Propagation Lids

Overview

Meet the RooTrimmer 6.3-Inch Tall Humidity Domes, a 10-pack designed to give seedlings, cuttings, and microgreens a thriving start. The extra height creates space for taller roots and developing shoots, helping plants reach a robust stage before transplanting. The clear lids also provide a direct view of moisture and growth, so you can monitor progress with minimal disturbance.

Why these domes stand out

• 6.3-inch tall profile offers ample room for vigorous early growth and deeper root development.
• Two adjustable vents (top and side) let you fine-tune humidity and airflow to suit your setup.
• Thick, BPA-free PET plastic delivers durability and reuse across seasons, even in busy grow spaces.
• Snug fit on standard 1020 trays keeps warmth and condensation contained, creating a dependable mini-greenhouse effect.
• Complete 10-pack with vent inserts included, so you’re ready to start right away without missing parts.

Versatile, real-world use

These domes suit a range of environments—from dry, high-desert rooms to chilly indoor germination stations. The adjustable vents help maintain a stable microclimate, while the transparent lid makes it easy to watch moisture build and roots begin to form without lifting the lid.

Practical tips for best results

• Place domes on heated mats to ensure even warmth across the tray.
• Open vents slightly during the day and close toward night to stabilize humidity.
• Handle with care to protect the clear lid and vent components, and clean between uses with mild soap and water.
• Use the 1020 tray compatibility to maximize space efficiency in busy grow spaces.

Durable design you can rely on

Made from sturdy BPA-free PET plastic, these domes resist cracking and buckling in daily handling. They’re built to be reused across seasons, supporting ongoing propagation projects—from tomato starters to tropical cuttings—and they provide visibility that helps you track progress over time.
