    • Great for rose cuttings!
Size: Large Light Kit
Review Image by Jacqueline Andersen
Review Image by Jacqueline Andersen
I am growing rose cuttings from my grandmother's roses. She passed in December 2025 and I wanted something special to remember her by. I was having a lot of difficulty keeping a humid environment for them until I got this. The dome doesn't sit quite perfectly flush with the base but Ive found im still able to get a great amount of condensation forming. Most of the domes I looked at initially are too short for rose cuttings but with the extenders on this dome, I get the height I need. I think my only complaint is there isnt a way to clip the extenders in place, either to the dome or the tray. The whole setups been pretty great otherwise. I finally have roots on one of the older rose cuttings so I am happy with the results I am getting with this product. ... show more

    • Highly dissapointed. Ac infinity the new Vivosun.
Size: Large Light Kit
I was actually hopeful for this figured for what they where charging it had to be good. Boy was i wrong. Immediately after opening it I noticed a Crack in the top dome. No way that happened in transit with how it was packaged so it had to sent out like that. After assembling the side extensions I set it on and it only touches the tray in 2 spots. Wobbles and wont seat at all. And if you have clone dome and use them regularly you know this seal NEEDS to be airtight or you will have puddles outside the dome. And it will lose humidity over time leading to fluctuations and killing your success rates. The lights seem to work. Thats the only reason I gave a star. That and the bottom tray is solid. Ive run AC infinity fans for over a decade now and seeing them go into these areas is giving me vivosun vibes. I dont have time to send things back multiple times and get my money back and wait another 12 days to have another delivered. Nor do most people. For this amount of money im shocked this has any good reviews unless.... well you know how reviews work. This is no better than my old sunblaster plastic setup. At least that one dont Crack and seats right. ... show more

Size: Large Light Kit
There are a couple of different options on this. I also have the one without the height extender. This one with the height extender has a more rigid dome. A lot more rigid actually. Not that the other one was weak, but this one is quality and will last for years and years. I run the lights at lowest setting for rooting African Violet leaves. Tray and insert are sturdier than competing humidity dome sets. Buy this one or any other AC domes. All are well worth the money. ... show more

Size: Large Light Kit
I bought this one and a smaller one to germinate tomatoes, peppers and begonias. There is no difference between the bigger one and the smaller one besides no vent holes on the lid of the smaller one. On my 5x8 i planted 1 seed per cell and got 37/40 to germinate using a heat mat set at an air temp of 77 degrees inside the dome. I read one comment saying the timer didn't work and it took me a few nights of to figure it out because there is an On brightness and an OFF brightness and you have to leave AC infinity timers on the mode you want them to use so in this case leave it on the start or off time. I do not have a problem with my cell leaking and I can't imagine how much water they have in there to cause it to leak. One comment was the lights don't clip in. Well it takes about 10 brain cells to figure out that they send clips for the lights to clip in. And yet I never saw any yt videos of people using them. Plastic is pretty stout and not flimsy like most planting products. The only complaint I would agree on is the lights are too short and makes the plants on the ends grow crooked. Not a huge deal since they won't be using that light for long. Very efficient package. ... show more

    • Too hot or leggy… pick your poison
Size: Large Light Kit
The parts are of high quality, however, the seedlings were either too hot or started going leggy when paired with the lights they offer. I ended up sticking the tray under my bigger lights but further away and they perked right up. AC infinity usually makes excellent stuff so this one surprised me a bit. ... show more
