Review: Functionality and Build quality - Quality build making it easier to move around and the light and timer is super cool. U have germinated seeds and maintain clones successfully in this dome. Ac infinity has amazing products and will continue to purchase this brand.
Review: Quality Without a High Price Tag! - My husband and I are passionate plant enthusiasts who love gardening, so we were in the market for a reliable germination kit for our seeds. I spent considerable time researching all kinds of options—from traditional, no-frills propagators with simple domes to more advanced automated humidity domes, hydroponic and fogging systems. In the end, we chose this kit from AC Infinity—and the results speak for themselves. Who needs a propagator with a water pump? Not us! This kit makes sprouting seedlings straightforward and effective, without the hassle or potential issues of a pump that can wear out or require replacement. It’s easy to assemble and includes everything you need to get started (except for seeds and growing medium). The full-spectrum LED light bars are exceptionally well-made, featuring high-efficiency Samsung LM301H EVO diodes. We especially appreciate the vented extension panels, which let you raise the dome height to accommodate taller seedlings. The circular vents are another thoughtful touch, allowing you to fine-tune airflow and humidity as needed. The entire unit feels sturdy and well-constructed, and the plant tray supports up to 72 seedlings—a generous capacity for this type of setup. When you compare the cost of a hydroponic propagator with a pump and similar site count, it’s clear this kit offers unbeatable value. The seedling mat includes a temperature controller to maintain optimal soil warmth, while the propagator features a built-in light timer to automate your lighting schedule. Together, these features make it effortless to create ideal germination conditions with consistent results. Overall, this kit has exceeded our expectations. We've consistently achieved at least a 98% germination rate with strong, healthy seedlings. Yet another high-quality product by AC Infinity!

## Questions & Answers

**Q: Why does it show the heating mat in the thumbnail if it's not included...?**
A: To show what can be used with it. Basically trying to make a sale

**Q: Are the lights available for purchase without having to buy the humidity dome? Already own the Ac infinity dome. Just need the lights now.**
A: I only bought the dome but the lights are sold separately

**Q: Hi, what is the heat mat and light setting for Cannabis seedlings?  Thanks!  :-)**
A: I set heat mat at 80 degrees.

**Q: What size coir plugs would fit in the seed tray?**
A: Here are the inside dimensions of an individual cell as per AC Infinity:
"Top is about 1.57in x 1.57in. Bottom is about 1in x 1in. Height is about 2.36in."
So, for example, a standard 36mm round Jiffy peat pot would not fit without squeezing it into the bottom (they are about 1.4in diameter.)

### ⭐⭐⭐⭐⭐ 100% Worth It!
*by H***M on December 9, 2025*

You get what you pay for! There are higher priced than others, but they are QUALITY!!!! I was able to clone my first 40 plants using these with an amazing success rate. The thickness of the dome makes a difference. Super easy to put together (I just glanced at the instructions and got it right). All the components fit like a glove!
