    Consistent warmth

These helped seeds sprout fast!! I live in northern Michigan so it’s necessary to sprout indoors ahead of planting season. I needed extra heat on my sprouts in cold areas of my home and these pads worked wonders!! Like magic!! So easy to use, unfold, link up and plug in! Done! Wella!

    A simple way to give your seed trays a jumpstart in colder climates
  

*by J***E on Reviewed in the United States on April 18, 2024*

I recently picked up a couple of these VIVOSUN seedling heat mats to give my plants a little extra TLC during the cooler spring weather here in Hardiness Zone 5B. I've got them set up in my 4-tier mini greenhouse, and so far, I'm really impressed with how they're performing.The installation was a piece of cake. All you have to do is unroll the mats, place them under your seed trays, and plug them in. No muss, no fuss. Each mat was perfect for the standard seed trays I picked up at my local garden center.Once powered on, these mats provide a nice, gentle heat that seems to be just right for germination. I'm not a pro and haven't measured things super precisely, but my basil, thai basil, oregano, sage, thyme, chives, lemon balm, and catnip seem to have no complaints. The heat feels very uniform across the whole mat too.I've also gotten them a bit wet during watering and there's been zero issues. They seem built to last.All in all, I've gotta give these VIVOSUN mats two green thumbs up. They're doing a stellar job keeping my seedlings cozy and thriving during these last few weeks before I can move them outside.
