VIVOSUN 2-Pack 48" x 20.75" Durable Waterproof Seedling Heat Mat, UL & MET-Certified Warm Hydroponic Heating Pad for Germination, Indoor Gardening, Greenhouse

I am very happy with these heat mats. I am controlling these mats with a Vivosun timer. The combination works flawlessly. The temperature control is acceptable and with the controller, very adjustable. They do not heat quickly. For me, that is ideal. They do not draw a lot of power while warming, and seem to not take much electricity to maintain the temperature once it reaches the setpoint. That is excellent. I have used Vivosun heat mats and timers in the past and expected them to still be high quality. That is exactly what I found. Very easy to use. I have never had any problems with them and they get water all over them almost constantly with timed watering. No issues at all. I keep the timers elevated out of the water spray, so the critical connections always stay dry. I am a fan of Vivosun products and will purchase them in the future.

They are durable. They still work. Makes seedlings pop quick

I love these mats! They're helping my plants so well heat distribution is good.

Seems to work reasonably well. The price is the only major problem. The mats are relatively flimsy, not heavy duty, but that shouldn't prevent it from getting the job done. If I remember, I will return to provide more details after my seeds have sprouted.

Yes, I first purchased "the other brand" because it came with a temperature control. It didn't heat evenly, and when I checked it with a temperature gun, it was uneven and fluctuating. THIS ONE IS GREAT. No cold areas.

Great value and work very well

Third year of use. They are crusted, filthy and still work perfectly. Excellent product. Have sprouted thousands of seeds with two mats. They stay wet all through sprouting process. Perfect temperature. Set them right under sprouting trays.

Works very well. No air pockets unlike the other similar product I purchased. Even heat distribution and very stable.

Brilliant ideal for my needs worked perfectly

As good as most of them on the market. If. You've never used 14 propagating seedlings You'll be pleasantly pleased by adding a little bit of favorable heat. Makes a huge difference in the total outcome and the quickness of german ration. Annoying that heat is not a factor mine are on aa Inkbird controller. I don't know how the maths work on On their own I presume I presume they have a thermostat in them. This projecular brand I buy other items for them and they Always have great quality.

Heat really well. However its an American plug rated to 120volts, dangerous in Ireland and the UK. Using this at 240volts brings it to 80watts, the matt is rated to 20watts. Good but not suitable in Ireland unfortunately unless you splash out on a transformer per matt.

Attention c'est une prise américaine. Du coup obligé de renvoyer le produit car je suis en France

Might work OK but I wouldn't know. It didn't come with a UK compatible plug. Why advertise it in the UK? Returned.
