Know before you buy
The vents allow you to gradually decrease humidity as your seedlings mature. By opening them, you can harden off your plants to lower humidity levels before transplanting them into a less controlled environment.
Yes, the system is designed to accommodate taller plants through the use of optional height extensions. These extensions provide the extra vertical space needed for larger clones to grow without touching the top of the dome.
No, the system includes a built-in timer controller. This allows you to manage your light cycles and adjust between four different dimming levels directly from the unit.
The heat mat is designed for consistent use to maintain steady warmth for germination. However, you should use the included adjustable dial to monitor the temperature and ensure it stays within the ideal range for your specific plant species.
The dome is sized to support up to 40 seedlings or clones simultaneously. This capacity is optimized for standard seedling trays, ensuring each plant has enough space for initial development.
The 3mm thickness provides a balance between structural durability and light transmission. It is sturdy enough to resist cracking or warping over time while remaining clear enough to ensure your plants receive maximum light penetration.
