The mat provides bottom heat, signaling the seeds to begin germinating. Large enough for a standard starter tray, this mat will work well with any Jiffy seed starting kit. It is easy to use; simply plug it in, and the mat will maintain the optimum temperature range for most seeds to germinate.
Designed for indoor use only, it maintains a range of 70-85 degrees. After the seeds have germinated and sprouted, remove the seedling tray from the heat mat and place the seedlings in a sunny window or under a grow light.

"We attempted growing from seeds for the first time last year in our cold basement. We just used lights and didn't have much success due to it being cold down there. For this year, we bought several heat mats and they are incredible! Three days after planting seeds we had sprouts."
"Worked tremendously well for all my pepper starts!"
"great for getting an early start on the garden!"
"All the products I have purchased this spring were top of the shelf and without them my garden would have been a bad memory. I have a abundant of plants to put in my garden and all ahead of the summer heat. Thank you for your product and I will use them for many years to come ."
"It works great. I have sat it up with a Wi-Fi plug and set to a schedule of 2 hours on and 2 hours off to ensure the temp stays at between 75-95 degrees."
"Work great in keeping seed starter trays warm. Room I have them in is a cold room, no heat source but my seeds germinates & are growing!!"
"Efficient and consistent heat distribution. My seeds sprouted in no time and were very happy. Fits a big tray."
"Well, it just works really well. I just got a crop of basil coming up. Seems to be a good temperature, not too hot, but comfy. I bought two so am looking forward to early April to get the garden started."
"I am in agreement with the others. No instructions given . My seeds have quickly sprouted, but what do I do next. I have myself googling to look for helpful information. For the price of the mat there should be instructions includeds."
"I bought two seed-starter heat mats around 3/1/2019. Plugged them in today for first time. Both are heating the seed trays well into the 80 degree Fahrenheit range. I use a digital soil temperature gauge to check on soil temp. My problem is that there are NO "operator instructions" in or on the box; just a bunch of legal/safety info. No info as to how many hours each day the mat should be working or how hot the pad will make the soil. Seems like this could actually be a safety issue if the mat has not been designed to only heat up to a maximum predetermined temperature (example 80 degrees). Is unplugging the mat the only way to control soil temperature??"
