SUNCORE S3, Waterproof Seedling Mat with Heat Controller 25x50cm, UL & MET Certified Heating Pad, for Indoor Gardening, Hydroponics, Germination, Cloning, 10" x 20.75"

This product instead of helping to grow lions mane mushrooms has killed the mushrooms, burnt THROUGH the container and also burnt the carpet underneath. This was on the 'low temp' setting. I only gave it 1 star because I couldn't give zero!!

This kept my germination dome warm and humid. The plants LOVE it. I'm glad I bought it. It's a bit tricky to roll it back up to store in the included bag... but mostly because I worry about rolling it up too tightly. I grow Devil's lettuce and using this with the Ac infinity germ dome I had leaves above soil (cotyledons) in 2 days.

Schafft tatsächlich 26 Grad. Tut somit was es soll. Gerne wieder

This heats evenly and kept my seedlings worm in a cooler part of the house. It did not have a timer so I just plugged it into a lamp timer. Simple and easy to use.

I didn't check before I bought it Looks great but yea

I was surprised by how good the quality of this mat is. The adjustable temperature really works, I tested the temperatures before trying the seeds on it. Low is barely warm, high is a little too warm even for my chilly basement, and I found that about 1/3 past medium turned out perfect. Almost all of my bell pepper seeds came up. I just ordered another of these so I can start the rest of my seeds at once. I am completely new at starting plants from seeds but this makes it easy. I highly recommend this mat!
