This system has it all! The plastics are top shelf sturdy and going to last me forever. The heating mat is super well made and the added controls to manipulate the heat levels is just brilliant (I have first gen heat mats from ACI without the controls, so this is best upgrade to a stellar mat already.) The vent controls on the dome are located in Read more about review stating The ONLY Propagation System you need for home gardening!!4 positions, one on either short side and 2 on the top, they turn effortlessly and are again top shelf plastic. The space for seedlings is abundant with 72 slots, they fit my jiffy pucks perfectly, the seedling tray has holes in the bottom for drainage into the main base tray, again the plastic is sturdy as hell here. Now the star of this package is the genius use of two mini light bars with tier 1 Samsung LM301H (H is for horticulture designations) The light bars are so seriously slick I wish I came up with them! The build quality is top notch with aluminum to keep the LED chips nice and cool. The LEDs themselves are domed with seriously clear plastic, removing any worry from environmental issues affecting the LEDs, the kicker here that was smart af, the domed plastion on the LEDs slots right into dimples on the top of the humidity dome, making them more secure when sat on top of the dome.

Its a very nice package.

The LEDs are bad-ass. The dome is a little cheap, but functions very well.

I was hoping it would be a little stronger, but it works fine. A hard plastic, with a dome lift, is the only thing not in this package: I wish it was. Something for ACI to work on later. The lights dont stick magnetically, and Read more about review stating Very Nice for $100.00thats why Ive given it a 4 star rating. I feel like that should have been standard; with any of their light bars with this company.

That said, not bad. Im happy with my purchase, and I know the products will only get better.

A controller with a temp, humidity reader, would also be nice. I understand that will make for an expensive unit, but I dont care.
ACI, will only get better, so I can wait.

Thanks for the great stuff, ACI: Good job.

Vibe high, and plant happy.
