Review: Pricey but worth it. - It’s a great product, with no issues. Even when paired with cheaper lights and heat mats (how I made buying the dome cost even out some). Very sturdy. Very easy to put together and use. Plastic has stayed perfectly clear and I have used it for some time now. A little pricey for a dome but worth it.
Review: Sturdy and well crafted - Easy to put together. I needed this in a hurry as I had some seedlings that grew in fast and grew in taller than expected. Well, now the little fellers are able to stand tall and do their thing. The whole set up is perfect. The quality is definitely there and really makes it worth what you pay for these. The humidity control is super easy, as you have multiple vents so you can really adjust as your seedlings grow.

## 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.)

### ⭐⭐⭐⭐⭐ Pricey but worth it.
*by B***D on October 1, 2025*

It’s a great product, with no issues. Even when paired with cheaper lights and heat mats (how I made buying the dome cost even out some). Very sturdy. Very easy to put together and use. Plastic has stayed perfectly clear and I have used it for some time now. A little pricey for a dome but worth it.

### ⭐⭐⭐⭐⭐ Sturdy and well crafted
*by J***K on June 1, 2025*

### ⭐⭐⭐⭐⭐ Wow- better than expected
*by E***N on January 4, 2026*

Ordered 2 of the medium size domes. First - the items came very well packaged with the components in separate very thick poly bags. This kept the acrylic from getting scratched which I really appreciate. Although I am trying to use less plastic, the poly bags are thick and reusable as humidity bags. The acrylic is high quality and completely clear ( not frosted as the ad pictures imply). It is thick walled and seems durable, there is no graduation in size from the top to the bottom. There are black plastic screws included that connect the riser panels that aren’t pictured. In short, I find the model I received better looking and of a higher quality than the photos in the Amazon ad.
