## Description

VIVOSUN 48"x20.75" Seedling Heat Mat and Digital Thermostat Combo Set : desertcart.in: Garden & Outdoors

Review: Works well... - We tried this for the first time a couple of years ago. Germination rates went up dramatically. My only complaint, and it's not really a complaint, is it would be nice if they offered a model with the corners notched out so they would sit flat in most shelving units, instead of part of the mat running up the vertical posts. (I hope that makes sense).
Review: Maybe should be 3 stars... - I bought 2 just before Christmas of 2022. They came very quickly. Two months later only one continues to work. I used one in the traditional way - laying (mostly) flat on a table with seeded cups atop in plastic totes. It has remained in its original location this whole time. That one is still working. The other one (dead one) was moved several times daily. I WAS careful with it, removing it gently from the lids of totes and keeping it (both of them, actually) relatively dry and kept it in a wide, loose roll. I thought this wouldn't be a problem since it was delivered in a roll, but I may have been wrong. I used plastic totes with the mats for bottom and top heat at night, removing the top mat in the mornings. I'm blaming the constant moving for the failure, but not absolutely sure about that. The thermostat still works for both mats, which is helpful. All of the mechanisms - wires/thermostats/plugs - are kept in their own dry tote. I had to bunch some rags beneath the bottom mat so the bottoms of the totes would make full contact with the mat - that mattered. And while I live in the deep South, there were many very cold nights. With both these mats going, it was warmer in the totes than in the house on some of these nights, so it was a good alternative for me since I have no greenhouse (I do cover the entire set up with thick plastic and blankets at night and remove them in the mornings). I suspect that these plants will do even better than those from a greenhouse since they will automatically be hardened off. The peppers show heat damage, but that was my fault as I had forgotten to remove the lids of the totes on a particularly warm and sunny winter day. But there are happy leaves coming above them and it won't be a problem. I'm ordering another brand to replace the mat that died and will compare and contrast as I go, since I'm hoping to increase my numbers next year. Overall I am very pleased with the one, and very disappointed with the other, yet grateful that it worked long enough to get me past the bulk of the cold weather. In the future, I will have to come up with a way to move and store the top mat during the day in a way that is even more gentle than I had been doing. This worries me, since I'd been so careful previously, I'm not sure I can accomplish this greater standard of care.

### ⭐⭐⭐ Mat works but don't count on having a Carrying Bag as stated in the Ad
*by J***. on 26 February 2026*

The heat mat is working adequately and have checked the temp of the mat using a Infrared Thermometer 774 gun. I haven't tried the Digital Thermostat yet and will update my review once I do. The only issue I have is the advertisement for this "package deal" which stated there would be a Carrying Bag for the heat mat for when you are done with the mat. My box did not have the Carrying Bag for the heat mat. I've reached out to Vivosun via email and after answering all their questions and back and forth for several days, they told me to contact Amazon. I reached out to Amazon and was told they cannot replace missing parts and I would have to do a return. Some people may not care if they get the Carrying Bag but I would like to have it for storage when done using the mat.
