Use the mat to a ~ 24x35cm Mini plastic to heat the greenhouse, which is now my sprouting Chilli plants :)
Works impeccable in conjunction with a universal bi metal thermostat (13), which the mat switches when temperature reached (here ~ 28 ° C) and then turns on when it is too low.
I chose the cable mat destroying them in order to integrate the thermostat which also super easy to work with a couple of cable lugs, all came in a case which has still rumgelegen and was thus comes much cheaper than the offered here Universal themostat as connector solution for about 40, which, however, the advantage also has digital display temperature. I have just the sensor of my 2 outdoor thermometer placed in the greenhouse for :)
There wick on my "sunny" balcony window unfortunately due to lack of heating in the vicinity is pretty cool (about 4 ° C colder than the rest of the room) and the floor again colder (basements, unheated ...) and there currently - 14 ° C, is a bit of insulation (chair cushions or Styrofoam is also) under the mat, since the mat with 16W of course is not super hot and such temperature differences would not grab.
The insulation grabs it but to heat the greenhouse at 28 ° C and must also be turned off by the thermostat times.
In particular, compared to the mats that are designed especially for greenhouses saves here quite a bit of money :)
