Heat Tray (4 Demi/5 Gallon Fermenter) With Free Timer Plug.
Purpose designed electric heat tray that will hold 4x 1 Gallon Demijohns or 1x 25 litre/5 gallon fermenter.
The Heat Trays are not thermostatically controlled so if the fermentation is taking place in a room that the temperature rises during the day then it is advisable to turn this off during this time. This item includes a small time clock which will switch the plug on at given times. Its good to only do this when your heating is off at night/early morning.
