This is for seedlings and seedling trays. It is preset temp and you cannot "set" any temperature. (Which is fine!) All my indoor grows and seedlings pop amazingly FAST with heating mats now. Very grateful to use them, and I have had good experience with this brand.

Couple things; 1.) I'm trying to grow an indoor vegetable garden living in an apartment as well as a desert. 2.) Still trying to get used to this whole gardening thing and learning as I go. That being said....what are you waiting for?! Order one of these now! Lol I've been trying to figure out how to have a better success rate on my seedlings. I would only get half, if that, to come up. I bought this heating mat hoping it'd help....has it ever! It has drastically increased the humidity in my seed starter containers and everything has taken off! I didn't bother getting one with a thermometer for the heat mat. After seeing the results, I wouldn't worry about getting one, either! Also, just as a side note; plants struggling to grow? Try using some Cal Mag (calcium magnesium). This has also helped out my already growing plants!

It's been going for a few weeks now without any issues... yet, but only time will tell how durable and safe this is. Heating pads and mats always seem like a fire hazard to me, so I was cautious about using one. I would say that there are 2 major downsides, first is that it is nearly impossible to get flat. It comes rolled up and due to the heating elements inside you really can't put pressure on it to flatten without potentially compromising the safety, so it is sort of lumpy which causes seed trays to tilt at weird angles resulting in water pooling in weird spots and spilling out of humidity domes. Not ideal, but could probably be flattened over a few seasons, or with books. Second is the lack of temperature control, if you're looking for precise temperatures, you're better off looking for something else. This seems to have a ~10-20+ degree F range above room temperature, depending on how much heat loss your containment area is. My basement is between 55-60 on a winter day, and this mat reaches around 65-80 with a grow light on. Seeds have been popping up relatively quickly so far, so that's a good start.

I purchased the 48" x 20" mat: MET certified Seedling Heat Mat, Seedfactor Waterproof Durable Germination Station Heat Mat, Warm Hydroponic Heating Pad for Indoor Home Gardening Seed Starter(48" x 20") . It arrived quickly and in excellent condition. As expected, the mat was rolled up for packaging - it flattened out nicely after I let it heat itself up for about an hour. I have various varieties of tomato and pepper seeds that I've started in 4" square pots in my basement (plus a bunch of bare-root strawberries that the nursery decided to ship on April 2nd ... to Colorado ... where the general guideline for putting plants outdoors is Mother's Day). The pots are sitting in plastic food service trays, 10 or 12 pots per tray, on a plastic table. The ambient temp in that part of the basement varies between about 65°F and 70°F, so the soil temp sits around 67°F. Way too cold for those seeds to germinate reliably. I put the mat between the table and the trays, then plugged it into a thermostat ( VIVOSUN Digital Seedling Heat Mat Thermostat Controller 68-108℉ ). I set the thermostat to 80°F. Its probe indicated an initial soil temp of 67°F. Even through the trays and with the low ambient and starting soil temps, the mat raised the soil temp to 80°F in about 4 hours. The thermostat is cycling on/off as soil temp moves between 80° and 81°F, drawing the expected 100W when it's on. Of course, there's a substantial soil temp hit (and re-heat time) when I water the seedlings - I should probably use warmer water. I did not insulate the mat from the table, so there's some heat loss there - I can feel it on the underside of the table. I suspect performance might be a little better if I put some cardboard and/or styrofoam between the mat and the table. So far, I'm completely satisfied with this product. UPDATE 21 APR 2018: I tried increasing the target soil temp to 82°F via the thermostat. With ambient temp in the basement dropping down to 60°F overnight during a few days of cold weather, the mat was unable to keep up. It was on 100% of the time and couldn't get the soil even to 80°F. This was not unexpected, as the product description says it "warms root area 10-20°F over ambient temperature". I put some 1" styrofoam (packaging from some assemble-it-yourself furniture) between the mat and the table. The mat is now able to quickly raise the soil temp to 83°F while only on about 70% of the time. (Average duty cycle calculated from total kWh used, total hours elapsed, and 100W). I may also replace the plastic food service trays with aluminum half-sheet pans for better heat transfer between the mat and the pots.

If you are just starting out germinating your own seeds or dont have a large garden, this seedling heat mat is perfect. It's inexpensive and has even heat that is just right for most seeds. The only drawback is that there is no heat control, but I still had great success using it and had all but 1 of my seeds germinate. I recommend this mat if you're just starting out germinating seeds or have a small garden and don't want to make a large investment in a seedling mat you only use a couple of times a year.

I have used this mat now for 2 growing seasons to start my seeds. The heat is consistent and the germination and growing plants have done well over this mat. If I was to order again, I might consider splurging to get one with a thermostat so there is less variation when the temperature on my porch changes.

Performs beautifully to get those baby seeds germinating. Super reliable and works great under plant trays. Keeps seedling trays at the perfect temperature.
