FAQs

How many seedlings or clones can this kit hold?+

The included seedling tray has 72 individual cells, allowing you to propagate up to 72 plants at once.

What is the purpose of the height extender?+

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.

Can I use a seedling heat mat with this dome?+

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.

What are the dome and trays made from?+

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.

How can I get the best results with this kit?+

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.
