11”x21” Vented High Dome with UPC
Features
- This dome is 6” high and designed to work with 10x20 greenhouse trays (#3465); for larger seedlings and cuttings.
- Vented Humidity Control: Features an adjustable sliding vent on the top to regulate airflow and internal humidity levels.
- High Dome Clearance: The extra-tall design provides ample vertical space for seedlings to grow taller before needing to be uncovered.
- Clear Visibility: Constructed from high-quality transparent material, allowing for maximum light penetration and easy monitoring of plant progress without lifting the lid.
Benefits
- Accelerated Germination: By trapping heat and moisture, the dome creates a consistent microclimate that speeds up seed germination and rooting.
- Precise Environment Management: The adjustable vent allows growers to harden off plants gradually by increasing airflow as they mature, reducing transplant stress.
- Protection for Young Plants: Acts as a barrier against sudden temperature fluctuations, drafts, and pests during the most vulnerable stages of plant life.
- Versatility: The high-clearance design makes it suitable not only for seeds but also for taller cuttings and microgreens that require a humid environment for a longer period.
- Resource Efficiency: Helps maintain soil moisture for longer periods, reducing the frequency of watering required.
