The included seedling tray has 72 individual cells, allowing you to propagate up to 72 plants at once.
The height extender adds vertical space inside the dome. This is ideal for when your seedlings begin to grow taller or when you are rooting larger clones that require more headroom before transplanting.
Yes, this propagation kit is perfectly compatible with seedling heat mats. Using a mat like the AC Infinity Suncore S3 Seedling Heat Mat can significantly improve germination rates by providing consistent warmth to the root zone.
The dome and seed tray are made from clear PET plastic for durability and light penetration, while the heavy-duty base tray is constructed from thick 2.2mm PS plastic to prevent leaks and support weight.
For optimal results, maintain high humidity by keeping the vents closed initially, then gradually open them as your plants develop to acclimate them. For an even more advanced setup, consider the complete germination kit which includes a heat mat and LED grow light bars.
