Perfect for My Gallon Kombucha Jars
I have 3 of these types of strip heating mats. I use them to go around my gallon sized kombucha jars during the winter and they work fine. They keep my fermenting kombucha at just the right temperature. Two of these mats I've had for years and only purchased another one fairly recently. I find them to be very useful and am very pleased with them.

Excellent quality
I have been using these seed starting heat mats for several seasons now and they are very durable. The material is exceptional and heats very evenly between 65 and 70 degrees, perfect for germination. Highly recommend.

Works, but automatic with no control
I'd prefer it to let you set the temperature but for the price it's hard to complain about it. Works fine, I'd just recommend to check the temperature every so often to be safe.

Simple, Waterproof, and Harder to Kill Than My Plants
These VIVOSUN seedling labels do exactly what they claim—no drama, no surprises. They’re sturdy, waterproof, and don’t turn into soggy cardboard the second you water your plants. Ink stays put, labels don’t fade, and they survive humidity like champs. They’re the perfect size for seed trays and pots, easy to write on, and rigid enough to stand upright without falling over every time you look at them wrong. I’ve used them in damp soil and humid grow environments, and they still look readable instead of “ancient ruin” status. Are they exciting? No. Are they useful? Absolutely. If you’re tired of guessing which plant is which or playing “mystery seedling roulette,” these solve that problem cleanly. Sometimes the best tools are the boring ones that just work—and these are exactly that.

It’s time to start some seeds and this jumbo pad is just what you need to utilize maximum space with the right amount of heat for germination. Great value for the money and easy to use
