If you want quality products that do what you need them to do and keep on doing it then ac infinity is the brand to go with. Their products just feel like quality and they perform just as good as they feel. I’m so glad they have focused so much on their line of indoor gardening equipment because it gives growers a high quality option. Anyway, these mats are perfect! I grow thousands of out her plant seedlings and I prefer to use a heat mat while germinating them. The past few mats have fallen short because they use a thermostat that must be inserted into the soil to read the temp. While this may not seem like a big deal, I’ve had the sensor come out before and narrowly avoided frying my seedlings! These mats however use a dial that you can tune to perfectly set your desired temperature (I use a laser thermometer for soil temps) not only is that helpful but it makes it much simpler to achieve your desired results. Another thing I really like about these mats is they are not bulky at all. The technology they use is infrared and not heat coils. Which means it’s EVEN HEAT and with no hot spots like coil mats have. I feel like that’s a much safer option as heat coils, while rare, can short out. They do take slightly longer to reach peak heat but does a few extra minutes really matter when germinating seeds? Not really. If you are looking for a high quality heat mat that will outperform any others you’re going to find, just do yourself a favor and go with these. They won’t disappoint!!

Me gustaron los tapetes, se sienten de muy buena calidad y si me funciona en conjunto con el domo de humedad también de ac infinity, ojalá los hubiera comprado al mismo tiempo para ahorrarme el envío, pero de ahí en fuera funcionan tal y como se menciona en la descripción 👍

This kept my germination dome warm and humid. The plants LOVE it. I'm glad I bought it. It's a bit tricky to roll it back up to store in the included bag... but mostly because I worry about rolling it up too tightly. I grow Devil's lettuce and using this with the Ac infinity germ dome I had leaves above soil (cotyledons) in 2 days.

This heats evenly and kept my seedlings worm in a cooler part of the house. It did not have a timer so I just plugged it into a lamp timer. Simple and easy to use.
