Product Overview

Studies have proven that plants with a root zone that is kept warm thrive and propagate at a much faster rate than plants that do not. Simply place the Seedling Heat Mat on a flat, dry surface under a seedling tray and plug the cord into a 120 V outlet. For best results, use propagation dome over the seedling tray and keep it under T5 fluorescent lighting or in a greenhouse lighting environment. Direct sunlight or high HID lights may be too intense for seedlings.

  • Warms root area 10-20 above room temperature
  • Speeds germination and encourages strong root growth
  • Fits snugly under a standard size seed tray
  • High quality, water resistant construction
  • May be used with a compatible thermostat for temperature control

Rated 4.6 out of 5 by 86 reviewers.
Rated 5.0 out of 5.0 by Not Just for Cold Climates I never would have figured that a seed germinating mat would be necessary in Southern California. I had seed germination within two days with seeds that took two weeks otherwise, I' impressed June 24, 2016
Rated 5.0 out of 5.0 by Good product. Good Price. HomeDepot had the best price and I pride myself in shopping around for good deals.I bought this because I was starting my seeds indoors and where I decided to put the growing tray was in a cooler part of my house. I read that the seeds like a warmer soil and felt if I was going to do something I needed to do it right the first time so I invested in the 20.5 IN. X 8.5 IN. SEED PROPAGATING SEEDLING HEAT MAT. It was the perfect fit for my growing tray. I was so pleased all my seeds sprouted and I believe the warming mat did a great job keeping the soil at just the right temperature for this garden project. April 19, 2016
Rated 4.0 out of 5.0 by Good Germination Rates Some of my cacti seeds require very warm temperatures to germinate, which is why I purchased the seed heating mat. I made a make-shift greenhouse by putting the mat on the floor of an aquarium. Seeds that required higher temperatures were placed on the bottom. Seeds that didn't require as much heat were elevated on a shelf so they could receive indirect warmth. The elevated seedlings have had a decent germination rate. The seeds directly on the mat are known for difficulty in germinating. They are taking a little bit longer.This mat provides great indirect heat. I have a plexiglass lid on the top of the aquarium to contain the heat. March 21, 2015
Rated 4.0 out of 5.0 by Looks good This seed propagating heat mat arrived well packaged and in good time. It is smaller than I thought. It is about as wide as a dish remote control. It is supposed to heat a standard seedling tray. When plugged in, the mat heats to about the low setting on a regular heating pad. The one problem I had propagating seeds this spring was poor root development. This heating mat is supposed to solve that problem by keeping the root zone warm. I can't wait to try it next spring. August 4, 2015
Rated 5.0 out of 5.0 by Does it's job The heat mats have kept the seedlings healthy overnight, ( I bought two), especially with the very cold evenings we've had lately. They are on a timer, so do not run all day. A good value for the price. Hopefully they will perform for years. May 17, 2016
Rated 5.0 out of 5.0 by Very good product The seedling mat did an excellent job at a moderate price. Even ancient seeds germinated. I would recommend it to others. I did find it a bit warmer than the average mat - which should be kept in mind, since for this price there is no ability to change temps. April 26, 2016
Rated 2.0 out of 5.0 by Not Heating Up Just bought the Viagrow seedling heat mat. I plugged it in and waited a half hour but I don't feel the heat when I touch the mat. Not sure if its working. It seems kind of lame. Perhaps the heat is so minute you cant feel it? I don't know if this is normal or I should return it. Maybe if I had another brand plant heat mat I could compare the heat to? April 14, 2016
Rated 4.0 out of 5.0 by Fast shipping I didn't expect this to work that well, but when I plugged it in and waited awhile it heated my plant bed great. Didn't expect it to work this well. Very happy and my plants are too. March 22, 2016
