MARS HYDRO 10''x 20.75'' Seedling Heat Mat with Thermostat Combo Set，Heating Pad for for Germination, Indoor Gardening, Greenhouse

Hält die Temperatur konstant warm, heizt recht schnell auf, wertige Verarbeitung.Temperaturanzeige leider nur in Fahrenheit. Würde sie sofort nochmal kaufen.

The controller is a bit large for the setup..Not sure how long it will last or how efficient it is.. time will tell.

Non serve a nulla. Da descrizione indica che sia utilizzabile per produrre birra (che era il mio obiettivo). L'ho testato prima di iniziare la produzione, e sfortunatamente nonostante tutti gli accorgimenti, non arriva alla temperatura indicata. Il tappetino non riscalda fino alla temperatura desiderata. Tutto qui. Effettuata la procedura di reso.

over a year and it's still going strong,, a really nice tool if you live in a colder area. the sensor can also be used as a thermometer in a dwc res for example without the mat plugged in .

I have several of the standard non controllable heat mats that work, but they only heat to about 6-8° over ambient temp. I got these specifically for cactus seedlings and they work well. I’m able to set a temp well above ambient and they’ll reach and maintain that temp giving me faster seedling growth rate and excellent germination rates.The controller makes it nice that you can plug it in with the light timer and have the heat off at night once seedlings get a bit older to produce a more natural day/night temp swing, this makes cacti seedling more hardy. I do several thousand cacti seedling in fall so they can stay in the germination tents over winter before I need the tents for spring veggies and these mats give me great results. The Ferocactus wislizeni seedlings in the included picture are 28 days from seed sowing date and are 2x the size they’d be with the old heat mats, they are pencil eraser size at less than a month from sowing.I’ll be buying a few more of these before long to replace the old style mats.
