Who This Is For
- You are starting small batches because your larger trays waste too much space and soil for limited runs.
- You are using height extenders because your clones hit the roof of standard domes before they are ready to move.
What We Found
- The height extender is the standout part because it lets you keep clones under cover for an extra week if needed.
- This plastic is noticeably thicker than the cheap shop-store trays that usually crack after just one or two cycles.
What Users Say
- Growers who switched to these vented lids say they stopped seeing mold since they can actually dial in the airflow.
- Users who move trays frequently found that the reinforced base tray does not buckle when filled with 40 wet plugs.

FAQs
How many seedlings or clones can this kit hold?
The included seedling tray has 40 individual cells, allowing you to propagate up to 40 plants at once.
Is the height extender necessary for seedlings?
While not strictly necessary for new seedlings, the height extender is highly beneficial for taller sprouts and is ideal for giving clones the vertical space they need to develop without touching the dome.
How do the adjustable vents work?
The dome has rotating vents that you can open or close to control airflow. This allows you to gradually reduce humidity as your plants harden off, preparing them for the open-air environment of your grow space.
Can I use a seedling heat mat with this dome?
Yes, this propagation kit is perfectly compatible with seedling heat mats. We recommend the AC Infinity Suncore S3 Seedling Heat Mat for consistent warmth to encourage faster germination.
What makes this different from other propagation kits?
This kit is part of the trusted AC Infinity ecosystem, known for quality construction. Key features include the extra-thick, durable base tray, a height extender for versatility, and a high-clarity dome for optimal light.
