Description
  • 10" x 20.75" heating mat to accelerate and improve the success of seed starting and germination.

  • Digital heat controller displays real-time mat temperature, which can be adjusted to exact levels.

  • Eliminates the guesswork of determining heat levels to germinate any seed with no risk of scorching.

  • Features innovative far-infrared film that warms faster and evenly distributes heat across the mat.

  • Crafted with IP-67 quad-layer PVC that is flexible, resistant to wear and tear, and easy to wipe clean.

  • Product Description: A warming seedling mat designed to improve germination success and accelerate your seeds' growth process by emitting precision heating. The seedling mat's steady 32-122 degrees F (0-50 degrees C) temperature range heats the rooting area by up to 20 degrees F above the ambient air temperature. It uses a durable quad-layer PVC that is resistant to wear and tear and is easy to clean and roll for storage. Achieving an IP-67 rating, the heating mat is sealed along its seams to keep water and dust from seeping in. This ingress protection is extended to the power cord, its connection specially sealed to prevent electrical damage from occurring.

  • Innovative Technology: Each mat for seedling growth is lined with an innovative far-infrared film that provides even heating distribution while producing softer warmth output than wire coils, protecting your seeds from scorching. Its connected digital controller supports this protection by allowing you to set your exact desired temperature. The controller conveniently displays the mat's current temperature, making it easy to program your preferred heating level and view the change in real time. Modify your seedling mat's temperature as needed without guesswork, which can otherwise cause seeds to rot due to extreme changes.

  • Applications: Best used for seed germination and propagation, this seedling mat is primarily set indoors (e.g., in basements and terrariums) to jumpstart the rooting stage. For best results, you may use a greenhouse dome over your seeds to provide humidity and supplement their sprouting. The seedling mat can also be used for home brewing and fermenting beverages, as well as heating pet enclosures for reptiles.

    Pretty cheap but surprisingly solid
    Color: Black
    This thing comfortably fits my 16” MacBook Pro. It does tilt a bit probably due to me screwing it to the underside of my wooden desk which probably isn’t the exact use for it, but it holds really strong and isn’t going anywhere. Combining this with a small USB-C hub for some USB As and and extra HDMI and a little bit of Velcro, this holder makes for a pretty solid option to hide you laptop away if you a surprisingly clean desktop-like experience, even if you’re on a budget and can’t afford a desktop. A proper thunderbolt docking station would go a long way with this as well.
