Product Overview

Studies have proven that plants with a root zone that is kept warm thrive and propagate at a much faster rate than plants that do not. Simply place the Seedling Heat Mat on a flat, dry surface under a seedling tray and plug the cord into a 120 V outlet. For best results, use propagation dome over the seedling tray and keep it under T5 fluorescent lighting or in a greenhouse lighting environment. Direct sunlight or high HID lights may be too intense for seedlings.

will this to keep orchids warm in a chilly house?

I was thinking of putting this under the pots of my orchid tray . With convection heating the plants. Would this be warm enough in winter? Wife keeps turning thermostat down on me and my plants.

Rated 5 out of 5 by from What a difference! The seedling heating mat worked great. I had never had really good results with starting my vegetable seeds indoors prior to using this. It never occurred to me that the potting soil might not be warm enough. Home Depot had the best price of all the places (online and otherwise) that I checked. Highly recommended!

Rated 3 out of 5 by from works when its not broken. I like the product and it does work. But after a week of use it just quite working. So I'm giving another one a try and see if it stop working again.

Rated 4 out of 5 by from works good out of box. I was expecting a flat packaging but came in a box circled and was afroid if it will work. It worked as intended. Seeds are coming out sooner than otherwise would have. Time will tell durability. Will recommend. Seems very costly for the small mat area. Cost should be reduced

Rated 5 out of 5 by from Works As Advertised - Seedlings Love It This is my first year starting my own seedlings. This heat mat is a good size for a couple of trays. It was simple to just plug it in and let it go. The seedlings took off. I read about external thermostat controls, but I did not see any need for extra pieces. The mat does a great job all by itself. I liked the bigger size (large enough for two trays) instead of the single tray size. It gave me more flexibility. I actually started one full-size tray, and then a week later started a second half tray, and then a third half tray. I would buy it again.

Rated 5 out of 5 by from A tremendous help in seed germination. I use this device to warm the Jiffy Pods during germination. While I haven't taken any temperature readings, this heating pad works very well and I had 95% germination success. It is well made, durable and very easy to use--just plug it in.
