Who This Is For
- You are switching to a vented dome system because your current setup traps too much heat and stunts early growth.
- You are adding height extenders because your cuttings often grow too fast and press against the lid before transplant.
What We Found
- The height extender is the best part of this kit since it prevents leaves from touching the dome and rotting.
- These vents actually stay where you put them unlike the loose plastic discs found on cheaper propagation trays.
What Users Say
- Users report higher survival rates for their cuttings because the vents allow for precise humidity tapering.
- Buyers who went through dozens of cheap trays say they stopped buying replacements after switching to this set.

FAQs
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. You can learn more about optimizing your environment in our AC Infinity in-depth guide.
