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.

So helpful after surgery.
Color: Solid Warm Gray, Size: 24x24x12 inch
Perfect support while recording from abdominal surgery. This pillow maintains its shape and is not overly soft. I used it vertically as a prop for watching television and then used it horizontally to prop myself up to sleep, once I returned to sleeping in bed. I used this daily for 6 weeks or so following surgery. The cover can be removed and machine washed. The non-slip nubbies are helpful. This pilllow is high quality and really helped to minimize pain and improve my sleep after surgery.

Nice wedge pillow but not enough...
Color: Cool Grey, Size: 24x24x12 inch
It came compacted and when I opened it expanded almost immediately, maybe took like 20 minutes to fully decompress. Its soft and comfortable and the cover is really nice. But it does have a strong chemical smell, which is normal for this kind of brand new memory foam, I just put it on a table with a window open near it and after maybe 24 hours the smell was almost completely gone. The problem is that I bought this to have a elevated position when sleeping but the 30° are just not enough for me. I wish it was at least 45° but I could not find any pillow with that amount of degree... it's either 30° or like 75° in the other position. At the base of the pillow there is a little ridge that is comfortable for the lower back but makes me slide down in the middle of the night so I end up almost laying flat with my neck on the base ridge. With my slim build my lumbar area gets some nice support but makes my head almost have a "fall backwards" sensation, I like having my neck have a "push-forward" position with my pillow, but when adding another pillow to try and get to a comfortable position it only makes me slide down even more... :/

Very firm and durable
Color: Cool Grey, Size: 24x24x12 inch
worked great for husbands surgery recovery. Very affordable, firmness was great, looked nice on the bed and also used it for the grandkids when they were watching a movie. Moved around with ease. Didn't use it to sleep with all night though. He could only make it half the night but that wasn't the pillows fault. It was the cast on his arm. Definitely did its purpose after surgery and the need to sit up in bed more. highly recommend

Perfect. I used it when I was recovering from hip surgery. Relieved a lot of pain in my hip and knee at a time when I needed relief.

Comfortable, firm, great for positional sleep therapy
Color: Cool Grey, Size: 24x24x12 inch
This is just what I needed to breathe better in my sleep, my doctor recommended a pillow like this for sleep apnea symptoms. I have an upcoming surgery too, so i'm glad I was able to test it out a week prior and see how it can help me prop up in bed. Feeling better about my upcoming recovery knowing i'll have this great pillow to support me!
