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.
winter, which she has to spend indoors.
She loves it! Sprawls out on it all the time.
Turned my other Tortoise friends on to it too.
They were using heat lamps. The heat lamps
were hiking up their electric bills, this pad does not.
