VIVOSUN Durable Waterproof Seedling Heat Mat 3" x 20" UL & MET-Certified Heating Pad for Hydroponic, Kombucha Tea, Brewing, Fermentation & Plant Germination

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.

Works great so far, keeping my 2x gallons of Kombucha F1 at 26-28°C, 78°-82°F.

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.

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.

Can get very warm well over 100 degrees. You will need a thermostat to control it so you don't cook your seeds.

This plant heat mat works great! It fits perfectly in my mini greenhouse. My plants are thriving this winter and have a ton of new growth.

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.

Works well to quickly heat up to 100F.

Die 20w sind perfekt für Pflanzen Aufzucht. Sie wird nicht zu heiß. Man braucht aber definitiv einen Regler mit Temperatur Fühler dazu.

Used this last spring to help germinate seeds and it works well.

Great product. Comes sleekly packaged. Heats up fast and hold temps for my seedling throughout the cooler evenings. Its a perfect size to fit a full tray for seedlings. Temps appear to stay fairly constant as I have a thermometer on it. My greenhouse creates a lot of humidity so its great that the mat is water resistant.

Super kompakte Wärmematte die meinen kleinen Keimlingen innerhalb von einem Tag auf die Sprünge geholfen hat. Überhitzt nicht und braucht nicht extrem viel Platz, perfekt für die Fensterbank!

Alles gut,gerne wieder
