Rated 4.0 out of 5.0 by CactusLady Good Germination Rates
Some of my cacti seeds require very warm temperatures to germinate, which is why I purchased the seed heating mat. I made a make-shift greenhouse by putting the mat on the floor of an aquarium. Seeds that required higher temperatures were placed on the bottom. Seeds that didn't require as much heat were elevated on a shelf so they could receive indirect warmth. The elevated seedlings have had a decent germination rate. The seeds directly on the mat are known for difficulty in germinating. They are taking a little bit longer.This mat provides great indirect heat. I have a plexiglass lid on the top of the aquarium to contain the heat.

I never would have figured that a seed germinating mat would be necessary in Southern California. I had seed germination within two days with seeds that took two weeks otherwise, I' impressed

Rated 5.0 out of 5.0 by Kathleen Good product. Good Price.
HomeDepot had the best price and I pride myself in shopping around for good deals.I bought this because I was starting my seeds indoors and where I decided to put the growing tray was in a cooler part of my house. I read that the seeds like a warmer soil and felt if I was going to do something I needed to do it right the first time so I invested in the 20.5 IN. X 8.5 IN. SEED PROPAGATING SEEDLING HEAT MAT. It was the perfect fit for my growing tray. I was so pleased all my seeds sprouted and I believe the warming mat did a great job keeping the soil at just the right temperature for this garden project.

This seed propagating heat mat arrived well packaged and in good time. It is smaller than I thought. It is about as wide as a dish remote control. It is supposed to heat a standard seedling tray. When plugged in, the mat heats to about the low setting on a regular heating pad. The one problem I had propagating seeds this spring was poor root development. This heating mat is supposed to solve that problem by keeping the root zone warm. I can't wait to try it next spring.

The heat mats have kept the seedlings healthy overnight, ( I bought two), especially with the very cold evenings we've had lately. They are on a timer, so do not run all day. A good value for the price. Hopefully they will perform for years.

Just bought the Viagrow seedling heat mat.
I plugged it in and waited a half hour but I don't feel the heat
when I touch the mat. Not sure if its working. It seems kind of lame.
Perhaps the heat is so minute you cant feel it?
I don't know if this is normal or I should return it.
Maybe if I had another brand plant heat mat I could compare the heat to?

The seedling mat did an excellent job at a moderate price. Even ancient seeds germinated. I would recommend it to others. I did find it a bit warmer than the average mat - which should be kept in mind, since for this price there is no ability to change temps.

I didn't expect this to work that well, but when I plugged it in and waited awhile it heated my plant bed great. Didn't expect it to work this well. Very happy and my plants are too.
