Just wondering if anybody here has the commercial heat mat from greenhouse megastore. Looking at getting one and have some questions. What thermostat goes with it and do you have to wire it? Also wanting reviews on I power heat mats. Currently have a vivosun and heard they are a huge fire risk? Also feel like it didnt heat right last year as it never turned off. It always said heating on the thermostat. Barely any of my peppers ever germinated and I feel like malfunctioning heat mat was to blame. Tia.
