Heating Mat (for shroomkits)
MAX/GO/MEGA kits always benefit from a heating mat, as a kickstarter (when below 23 °C).
An OHM/X kit never needs it!
Never put the grow kit directly on the heating mat. Always put something in between to 'ventilate.' Such as a folded towel. If the grow kit gets too much direct heat from the heating mat, the mycelium will loose all its moist.
Use the Heating Mat for the FIRST 2 DAYS ONLY, right after setting up the kit. After 2 days, the grow kit is kickstarted, and does not need extra heating anymore.
If you use it for more than 2 days, the brick may become too dry. Therefore, cannot grow shrooms.
It's recommended to get a mycelium Thermometer in combination with the heating mat.
