Growerology Greenhouse Warming Mat | Seed Heat Mat with Insulation for Germination, Hydroponics & Plant Propagation - Waterproof MET Certified Plant Heating Pad, Indoor & Outdoor (10" x 20.75") 1PC

Nice little heat mat. I have a very small garden and I needed just a little warmth for germinating my seedlings. I am trying to stay away from buying a bunch of lights and plastic containers. I used peat pellets and recycled produce containers from the grocery store in a ceramic bowl and I have greenhouse buckets paired with this new heat mat to keep my seedlings warm until they sprout and go outside for some sun. Once I got my sprouts, this rolls up nicely and is easy to put away until next season. There are no controls for temperature, just plug it in and warm it up. I live in a warm climate and just need a little bit of a temp boost to get great germination. The included thermal mat is a nice touch, too. I am very happy with my purchase.

OK! so this heat mat is great. My reason for purchasing was to germinate cannabis seeds. If that too is your reasoning your in luck because I have figured out the trick to perfect germination using this mat. Put the seeds in a Cup of tap water for 24 hours then put the seeds(even if they haven’t cracked ) in a folded damp paper towel. Then put that paper towel inside a plastic bag. Yup..we’ve all been here right ? Here’s the trick.Take the plastic bag ( keep it unzipped) and put it in between the reflective mat and the heat mat. Keep it in the dark with the heat mat on for another 24 hours and the root will tap. Germinated 6 different seeds at once this way with 100% success.

This seedling heat mat works perfectly for me. It comes with an insulation mat that should be placed underneath the heating mat as a buffer to help prevent heat loss downward. Also has a 6' cord and the dimensions are 10"x20 3/4". Couple things I feel I should point out. According to the item description here on Amazon, it says it's waterproof but in the manual that comes with the mat it says water resistant. Since we're dealing with electricity and water I'd say that's a huge difference. I err on the side of caution and do my best to not get it wet. The next thing is, this mat gets pretty hot when plugged directly into the outlet. I'm talking roughly 110 F degrees hot. If you plan on using this for seed starting and seedlings you're definitely going to want a thermostat to decrease and regulate the heat cause otherwise you'll cook the roots of your young plants. I use a thermostat set at 75F degrees and that works well for me. Since I have had no problems with this mat for two growing seasons yes, I would buy this again. I hope this helps.

I recommend this mat. It certainly does what it is supposed to do. It appears to be well made with a long cord which is important for placement. You don't have to be near an outlet. Also the heat shield is a nice touch.. My only criticism is the raised hump where the electrical cord enters the mat.. You can't set your tray at that location because the hump will cause the tray to tilt.. It wasn't a problem for me because my trays are shorter than the mat and so the humpdoes not interfere with the tray placement on the mat.. I have a thermometer on the mat next to my tray and it has consistently read 84 degrees. At first I thought that was a bit high but that does not appear to be the case since I have started to see healthy growth. Tje bottom line is that this is a good product and I recommend a buy.
