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.

Quality good. Just like my handles to match and got two colors- very distinctive two colors- pale and brown- on fork. Customer service basically just said comes from different parts of tree and to deal with it. Wish they’d dealt with it when selecting for shipping to at least choose two that were close to each other. Was not a customer friendly response. Will not be buying from this company again
We’re very happy with all of our products from Bootstrap Farmer. High quality and easy to use. The mat works great and have had great results so far!
I’ve used Bootstrap Farmer for various plant propagation supplies and have never been disappointed. They carry quality products and their customer service has always been top notch. This is the second heat mat I’ve bought from them. Highly recommended!

This is a quality product. I am using it to grow the seedlings in my greenhouse(zone5,Chicago area). I was able to get 55-60 Fahrenheit for my plants when outside were 20 Fahrenheit. I have to mention that the plants are in a well insulated woodbox inside greenhouse covered with a frost blanket. Good costumer service.
