Keeps my Fermenting Kombucha Warm
I use this to keep kombucha at a good temp while fermenting. It works perfectly for this application on a one gallon jar. I was a little worried about temperature control but it keeps the liquid at the perfect temp. I can't speak to it regarding plants, but if you're trying to keep a gallon of liquid warm, this will do it.

Nifty proofer
Love it! It rolls back up into its bag with no problem, it heats perfectly, I'm very pleased. Proofs two loaves of bread faster than the proof setting on my oven.

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.

Gets a little warmer than expected
It gave my seedlings enough warmth to go from 35% germination early to 95% germination in early season. One got cooked on an unreasonably warm day. Everything else was great.

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!

Perfect. I was worried that I would have to have the thermostat along with the mat but at least for me the mat would great on it's own. One seed that I was trying to sprout for several days was doing nothing but it and it's little brother that I put in a little plastic cup of dirt along side the first then popped in 2 days.

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.
