Review: Great heat mats for cacti!!! - I have several of the standard non controllable heat mats that work, but they only heat to about 6-8° over ambient temp. I got these specifically for cactus seedlings and they work well. I’m able to set a temp well above ambient and they’ll reach and maintain that temp giving me faster seedling growth rate and excellent germination rates. The controller makes it nice that you can plug it in with the light timer and have the heat off at night once seedlings get a bit older to produce a more natural day/night temp swing, this makes cacti seedling more hardy. I do several thousand cacti seedling in fall so they can stay in the germination tents over winter before I need the tents for spring veggies and these mats give me great results. The Ferocactus wislizeni seedlings in the included picture are 28 days from seed sowing date and are 2x the size they’d be with the old heat mats, they are pencil eraser size at less than a month from sowing. I’ll be buying a few more of these before long to replace the old style mats.
Review: Great seedling mat!! - I recently purchased the Mars Hydro Heat Mat with Control for my indoor gardening setup, and I have been extremely impressed with its performance. This heat mat has been a game-changer for my seed starting process, providing consistent and gentle heat to promote healthy seedling growth. One of the standout features of this heat mat is its precise temperature control. The included thermostat allows me to easily adjust the temperature to suit the needs of different plants, ensuring optimal germination and growth. The mat heats up quickly and maintains a stable temperature, creating the perfect environment for seedlings to thrive. I also appreciate the durability and quality of the Mars Hydro Heat Mat. The mat is well-made, with high-quality materials that feel sturdy and long-lasting. It's also water-resistant, which is essential for indoor gardening where spills and moisture are common. Another great feature of this heat mat is its energy efficiency. Despite running 24/7 during the germination period, I've noticed no significant increase in my electricity bill, making it a cost-effective choice for indoor gardeners. Overall, I highly recommend the Mars Hydro Heat Mat with Control to anyone looking for a reliable and efficient heat mat for their indoor gardening needs. It has exceeded my expectations and has become an essential part of my gardening setup.
