This was so easy to use. The temperature is consistent - it does not have a thermostate but this has made my seedlings are spouting and are much happier! The value was great - I shopped around for other heat mats in our local nursury and they were very (VERY) expensive. This is water proof and the length easily covers two of my trays side by side. It is not too thick, seems to high quality and functions as I need it to. Your sprouts will thank you! Read more

Just received a day ago but so far they work great. Temp has been steady, my seeds are germinating. Seem to be great quality and ships extremely fast. No smell, instructions were very detailed but not necessary, very easy to use. Read more

Maintains a good temp to help seed germination. Cost is negligible. Doesn't have a thermostat but I used an instant read baking thermometer to verify heat output. Temps stay within a degree or two. I've noticed a definite improvement in seed germination. I just ordered the same set of two mats for my daughter! Read more

Works great, just warm enough. I start my seeds inside around mid January. Using 1.5" by 1.5" trays, laid out on a restaurant style sheet pan, roughly 14 rows of 9. Place the warmer on an old bath towel and the sheet pan on the warmer, the towel helps insulate the pad keeping the bottom of the sheet pan warm, but dry. Add a few shop lights. You might need two pads for the larger pan if your in a really cold climate (I live in SC). I'm getting great germation. Read more

Using it for fermenting kombucha, kefir and other things. Works really well and with a smart outlet you can regulate the temperature if you have a temperature probe. Read more

Note - I did not use these for seed germination yet. I used one for resin crafting - the other will be used for seed starting when it's not 5000 degrees outside here in Florida. The heat level is consistent, but not variable. There are no switches or knobs to adjust the base setting. It plugs into a standard outlet. The mat itself is a smooth matte vinyl, so I did cover it with parchment paper before I used it for resin in order to avoid making a huge mess. It really helped remove the stubborn bubbles in my resin dice. There is a warning that this, like most electronics, should not be submerged or exposed to standing water for a long period of time. Make sure you are using something with drainage holes OR have your seedlings otherwise contained so the water doesn't get on the mat. Anything that does spill wipes off quickly. This is about the size of a large desk mat and is relatively thin and non-obtrusive. The cord does not have a swivel head, so placement is important if you need things to stay level. It would be a great modification if they made these with a rotating/swivel outlet plug, but alas. The vinyl seems sturdy enough, but I do foresee it cracking down the line. Just be careful and avoid water intrusion. Read more
