Ohuhu Seedling Heat Mat Heated Propagator 2 Pack, Plant Heating Mat Plant Warm Mat IP67 Waterproof, 21W Hydroponic Heating Pad Greenhouse Heating Pad for Seedling and Germination 10"x 20.75"

Does what it says on the tin. Every single seedling germinated in a weed. As a newbie gardener I could not believe my eyes.Only thing I would say is make sure you water plants regularly as the heat can dry them out in their pots

I use to mat when making sourdough to get an even temperature for my starter and dough. I will also use it for my seeds next year.

The Ohuhu Seedling Heat Mats are a solid option for promoting seed germination and plant growth. They are well-designed for their intended purpose, providing consistent warmth to support seedlings and young plants. The mats are waterproof (IP67 rated), making them safe for use in greenhouses or hydroponic setups where moisture is present.However, it’s important to note that these mats do not allow for precise temperature control. I initially bought them hoping to have that feature, but unfortunately, they only provide a consistent baseline heat without the ability to adjust the temperature. For those who need more control over specific growing conditions, a different heat mat with adjustable settings would be a better choice.That said, these mats are reliable, easy to use, and durable for general plant propagation. They work great for straightforward seedling and germination tasks, as long as you don’t require fine-tuned temperature regulation. If this meets your needs, they’re a worthwhile investment.

Value for money, getting my Tom s&cucs of to good start

As described

Great and easy to use, gets upto temp quickly

Does what I needed it for. Only gave three stars as it is made from a fairly rigid plastic which comes rolled up and consequently doesn't lie completely flat unless the item on top is heavy

Good work well ,so far ,not totally waterproof according to instructions and for green house or indoor use .read before buying.I use in greenhouse with caution .
