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

It's a nice heat pad. I have had this for years, and after rolling it up time and time again, it still works! The germination rates are fantastic compared to putting your seeds by the fridge or something. If you're looking for a high-quality heat pad, then you've found it.

This heat mat is a game changer! I used it with the Gardzen 10-Pack Seed Starter Kits, and together they made the perfect setup. The mat warms up evenly and stays at just the right temperature to help seeds sprout quickly. I had the best germination rate I’ve ever seen—every seed came up! It’s durable, easy to clean, and does exactly what it promises.

Heats up just enough to feel warm without becoming a fire hazard. Glad to have something to warm my tiny tropical starter plant.

Nice even temperature, glad I decided to try it, plus reasonal cost.

This heat mat is awesome! Living in Northwest Ohio, this mat allows me to jump start all of my bulbs and tubers and get them growing before the spring planting season. We had previously purchased a pair of Vivosun 10-inch by 20.75-inch heat mats and they worked well. This spring we added to our collection by purchasing the Vivosun 48-inch by 20.75-inch mat and, wow, now we have so much more capacity! We set up the mat on a 6-foot folding table in our three-season room and started the growing season in early March. Within two weeks my canna lilies, elephant ears and dahlias were all sprouting and getting big. The size of the mat is great, providing enough space and nurturing heat for between 55 to 60 4-inch pots. The mat keeps the planted pots about 10 to 15 degrees warmer than the air temperature in the room, which is ideal for kickstarting germination and developing strong roots. If you are a serious gardener or just want to get an early start on the growing season, I would highly recommend a Vivosun heat mat.

Works well cost effective

Vivosun makes really high quality products, in my opinion, and this seedling heat mat is no exception. Just plug it in and you're ready to roll! Makes germination a much more efficient process.

Best Mat to germinate my seeds. Heats up just with enough warmth and I had my vegetable seedlings growing in no time! I used this in the winter and it worked!!!
