The MET Certified 2 Pack Seedling Heat Mat by Seedfactor is a fantastic addition to any indoor gardening setup. These waterproof and durable heat mats provide consistent, gentle warmth that helps speed up germination and promotes healthy seedling growth. Measuring 10" x 20", they fit perfectly under standard seed trays and work well for hydroponic, indoor, and greenhouse gardening. The mats heat up evenly without getting too hot, making them safe for delicate seeds. I also appreciate the durability and waterproof design, which adds to their longevity. Whether you're starting vegetables, herbs, or flowers, these heat mats create the ideal environment for strong, healthy seedlings. A great value for a 2-pack—highly recommended for any gardener!

Works as should! It’s a hard mat to roll out and place something heavy on it to flatten it out before you put seeds on them. Hopefully they speed up germination. Otherwise easy to use. I had germination within three days!

Loved the 3 rolled heat mats! Just remember to mist/ water your trays. Plants grow faster and need the water often! Like every day and remove to larger pots when 1” high. Heat will dry roots and plant goes wilted when heat pad is left on after plant emerges! I will be buying 2 more in Feb 2025!

I bought a bunch of these heat mats to help me germinate veggies for my garden. This would be my first year starting seeds indoors versus direct sewing seeds. With our winters stretching, my growing season is steadily decreasing. Unfortunately, there is very low direct sun and no heat in the basement. So, I purchased these to help with my process. As you can see: I filled a small nursery in my basement with domed germination trays. These heat mats worked very well. Notice the dome is full of condensation. There were no cold zones on the heat mats. They helped to create a lot of condensation so I didn't have to water one bit to get the plants to germinate. I simply hydrated the soil before planting seeds and the heat mats and grow lights did the rest of the work. It was almost as cold in the basement as it was outside once seeds germinated. As a result, I did leave the heat mats on while waiting for it to warm up enough to transplant. I do have a few issues/notes. There is no temperature gauge on this unit. It's either on or off. I would also like if there was a timer on this unit as there were times when the basement heated up and the units didn't need to be on. But, alas, up and down the steps I went. 😩😄 I would also like if these units could be plugged into one another like some Christmas light plugs. Another concern is that I'll have to figure out a protective boundary. I had zero issues with sparks but 1) these units are not grounded so I was always concerned with them slipping out and 2) when lifting domes, condensation drips everywhere. I was very concerned about water splashing on the surgery outlets and the impact. I will jerryrig something next year just for my own peace of mind. Overall, it was a good buy. I bought 6 or 7 sets (of 2) in March'ish of 2021. I unplugged them all in late May (from 3 different pricy but safe surge protectors) when plants were able to be transplanted. I look forward to using these next year. They are stored inside the nursery just laying flat on the shelves. I'll definitely give an update next Spring if they don't work. But, I'm hopeful.

I’ve had this for 2 growing seasons now and they still work great! Seeds germinate well in them. It doesn’t burn the surface they lay on and seems like the perfect temperature for starting seeds indoors.

Placed these in the bottom of a small plastic shell greenhouse. Everything sprouted very quickly

Give these a chance. They didn't feel warm to touch, but they must be working because in 1 week I have seedlings. I am using them under a Ferry-Morse seedling starting tray.
