How to Use a Seedling Heat Mat

Heat mats are a great tool to use for winter germination.  Heat mats are waterproof and easy to clean, so there is no need to move plants off the mat during watering. The mat is designed to stay on 24hr/day. Ideally, you will want your soil temperature to stay consistently between 65˚F-80˚F. 

For more precise temperature control these can be used with our digital heat mat temperature control.

Benefits of Using a Seedling Heat Mat

Seeds love warm, moist environments during germination. Being able to provide those temperatures earlier in the spring means earlier tomatoes at the market. Want earlier pumpkins? They need to be at least 85˚F to germinate. Heat mats can provide those perfect conditions, increasing growth rates. Being able to cycle through propagation in nearly half the time may mean more crops end up in the ground. Seedling heat mats are also useful in microgreen production.  Add heat mats into your production for more successful germination rates.

Makes an older family mattress feel brand new
There’s an older mattress in my place that everyone avoids because it feels too worn in the middle. Instead of replacing it, I decided to give this topper a shot. Once it settled on the bed, it added a thick cushioned layer that helped level out the whole surface. Lying down feels smoother, and the middle no longer dips the way it used to. The fabric feels cool when you touch it, and it keeps that same feel even after staying on it for a while. I thought a thick topper might hold warmth, but this one keeps the air moving enough that the bed stays comfortable throughout the night.

Helpful upgrade when staying between short-term housing
Laying it out was quick, and once it settled, the bed instantly felt gentler on the shoulders and hips. The padding feels thick without being bulky, and it molds just enough so that you feel supported without sinking. The airflow is surprisingly good. Even after lying still for long periods, the surface never turns warm or clammy. That was important since the mattress underneath didn’t have much ventilation.

bury me in snuggle sac!!
soo i’ve purchased 6 of the fuzzy blankets, 2 packs of the socks, the cardigan, and now this gem of a cooling blanket! im usually a heavy fluffy blanket person, regardless of season or temperature, but living in florida it’s sometimes a struggle. figured i’d give this one a try since i’m obsessed with snuggle sac. the blanket is very thin, intentionally, and is such a deliciously soft and unique material! the one side is cooling and really cold to the touch! both sides look very rich and high quality. definitely makes a difference so i’m not waking up hot anymore! in order to replicate my heavy blanket habit, i use the snuggle sac ribbed blanket on top of it, and can always remove it in the night. so happy with my purchase! always keeping my eye out for new releases from them.

Cools quite well, about 85% but works well for hot flashes
Being in perimenopause I tend to have hot flashes at the most inopportune times, especially in the middle of winter where I'm sleeping practically naked and everyone in the house is sleeping with hoodies and sweats and extra blankets. I just found out that one side is extremely cooler than the other and the first night I had it I washed it gently dried it in a very light, delicate setting on my dryer. In fact, I didn't let it dry all the way and let it hang up and the first three nights I slept with this blanket. I slept an entire 8 hours instead of the usual three because hot flashes like to do that to you. Wake you up at 2:00 in the morning or 5:00 in the morning when you have to get up for work in an hour. It's very light. It smells great. It's very soft and one side like I said is cooler than the other and you will feel so much better wearing this or sleeping with this rather. I'm
