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!

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!

I spent some time reviewing different options for seed/clone propagation from simple trays to auto cloners. Decided on this kit as it had everything needed for a good solid start and had a dome extender for taller clones. The kits comes on one box and was well packaged to prevent any damage. Everything appears to be well made and thought out. Even the packaging was a step above most less expensive options. Items were protected with heavy plastic zip bags, foam inserts and cardboard. The humidity dome is solid plastic and should not break with casual handling. The dome extender is easily put together with included screws/wingnuts. The extender allows for seedlings up to about 10" in height to fit under the dome. Several other reveiws noted that they didn't receive the extender. There are several products offered in the product description and the Large Dome kit does not include the extenders. Be sure the check the specific product you are ordering to insure it includes the extender if you want that. All other items included in the Full Dome kit were exactly as described. The seedling tray is even a good plastic thickness to last over many uses. The seedling openings are 1.5"x1.5" at the top and slightly taper down towards the bottom. Rockwool cubes of 1.5" square size will fit all the way down in these. There are two dome lights which fit into notches at the top of the dome not tight enough if turned upside down but not sloppy either. As some reviewers have noted, the dome lights extend almost to the edge but are one LED short on each side. I didn't see this as a defect but rather the way to kit was designed in case you choose to use different lights than what was included in this kit. The light controller has several scheduling options so you don't have to use a timer. The heat pad is a bit longer than the dome itself. It's controller is more simple in that it just adjusts from low to high but no exact temperature reading. All in all, this kit is well made, includes all that you need to start or for small operations. You can certainly get by with DIY options or buying everything piece by piece. But if you'd rather have everything in one set and ready to get started for a reasonable price, this is a very nice kit.

Size: Large Dome Kit
The quality of this tray is High. I do wish the cells were a little more sturdy BUT the kit is worth the money, esp considering you can place different seed trays within the watering tray, I also wish I purchased the kit with the lights. But I would definitely buy this whole kit again. This is a great kit for all skill level gardeners.

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.

It was better than i even expected. Well packaged! Very high quality heavy duty plastic tray and dome. Easy to assemble and program the lighting. I bought 3 total. I would highly recommend this kit for seed germination ahead of the planting season.
