Great for starting Ambrosia Corn and Heirloom Brandywine Tomatoes
I bought the two-fer pack. Best value. I can run 4 of the 10 x 20 inch grow packs on one heat mat. Each 10 x 20 grow pack holds 3 x 6 starter posts. This is the way to go, to start slow to start heirloom tomatoes, the tasty Brandywine Red or Black, 2 weeks at 80 F actual soil temperature or fussy to germinate sugar sweet corn like the fussy but very tasty Ambrosia corn. I am starting Ambrosia corn beginning of March for hand planting starts in my community garden plot when the soil temperature is 60 F. This is pretty aggressive, and one could not do by sowing seed outside in soil at 60F. I will have corn 6 to weeks before anyone else. These tomatoes and Ambrosia corn require germination soil temperature of 80 F degrees. Since I am using near a sliding door window, the temperature probe under neath a mini pot in a slab pot holder, when I set a temperature of 80 degree in feedback control mode, but since I am using paper coffee cups to grow in, 4.5 inch tall, naturally the soil temp is cooler at the top, as I measure with a separate plant thermometer. So I dial up to a 96 F temperature setting as an offset with the controller to get a 80 F one inch from soil top temperature. All this offset is perfectly normal. Ambrosia really wants 80 F to sprout even at an 85% germination rate. Heat mats really well made, easy to set up, easy to control temperature. Would buy again, but won’t need to since so well made. Easy to set the control settings. I think this will be a great gift for my gardening friends also.

Nice heat mat.
I have my amaryllis on this heat mat right now, and they love it!. My cat also likes it! I have bought 3. I haven’t used it for seed-starting yet. Will give updates as I use them more.

Works great and here’s a trip for mushrooms –
The product works great out of the box and operation is straightforward.I got these to keep some pf tek cakes warm that were getting cold at night.You might be aware of the fact that most mushroom cultivators advise against using these mats, mostly on the concern that these will ‘cook your cakes’ so to speak. More often than not, they’re considering the use of a heating pad without temperature control options.So here’s what I did – took an old cotton shirt and wrapped the mat in the shirt. This is to help retain heat but also to ensure that the temp of the cake can not be heating to more than the temperature cutoff setting.Next when installing, place the temperature probe between the shirt (or other cloth barrier of your choosing) and the mat. Set one of your jars or another solid object on top of the probe to hold it firmly between the mat and the shirt.Now your cakes cannot be heated to more than the cutoff temperature. You may have to adjust the temp setting and check your cakes with a digital thermometer to get things dialed in.It’s only 20w so power consumption is low.My one ‘concern’ about the unit is the control relay. Whenever it turns on or off, the box makes an audible ‘click’. It’s not bothersome to me, but it had me wondering how long that switch would last.

Not effective, broke within 2 months.
TLDR: the heat mat is very weak / not effective in a New England basement, the temp regular broke after 2 months of use – no longer turns on.The seedling heat mat wasnât able to keep desired temps in my basement. Ambient basement temps of 50-60* werenât extreme, but the medium could not reach or hold above 70 – although different heat mats plugged into the thermostatic switch were able to do so.Unfortunately, the thermostatic switch burnt out and will no longer switch on after less than 60 days use. The one stat Iâm giving is because the suction cup on the temperature probe actually worked great, as opposed to other temp regulators / probes Iâve used.

Es de buen tamaño y a un precio bastante reducido. Con ella podrás germinar tus plantulas de chile en espacio cerrado durante el invierno.Estoy muy contento con mi compra.

I bought 2 of these mats that are the perfect size for my rack. Having 2 of them was just right for planning out this year’s garden. They work amazingly! I’ve had them running non stop since March 12th with no problems.I will point out that the cost has gone up since I bought them so maybe buy them before or after the season.
