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!

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.

I was genuinely impressed by how sturdy and well-made this seed starter kit is. The trays are thick, durable, and a great large size — no flimsy plastic here. It comes with both a heat mat and grow light, which makes the whole setup feel complete and absolutely worth the investment. My only wish? That it included some form of humidity control — that would take it from great to amazing. Still, for what you get, this kit is a solid 5 stars.

This is a wonderful heavy duty humidity dome that will last longer than many. Very nice to have the extra levels to increase height as seedlings/cuttings grow taller.

This unit from AC Infinity is a great little "greenhouse". Everything you need to grow flowers and vegetables for the spring growing season. Just provide the seeds and potting mixture and you are ready to grow! I purchased some biodegradable growing cups and they fit perfectly in the growing slots for this unit . I am thinking it will make for an easy transplanting session when the plants are large enough. This unit is sturdy with a nice thick dome and base. I would definitely not hesitate to purchase any AC Infinity product in the future!

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.

I almost gave up on trying to propagate from cuttings. Solo cups held together with medical tape just weren’t working and I lost some cuttings. Cue this thing- I added the line type lights with a timer after the fact and my new cuttings are doing great. It’s super sturdy and maintains reasonable humidity.

Definitely a sturdy piece of equipment made from a heavy plastic material, not like the typical flimsy humidity domes you'd find in hydro shops. It is a bit overpriced for what it is, but I guess you could consider it a buy it for life kind of investment. I usually love AC infinity quality but this one loses a star because of the electronics. For some reason, this model has an issues with the controller making a quiet, but there nonetheless, screeching sound. It's a little annoying. I thought it was a product defect, but exchanged it just for it to have the same issues. The lights themselves are strong and I find myself not needing to go higher than 10-20% intensity for smaller clones. I'm very happy with the product, nonetheless.
