Did a quick search nothin specific found so here goes...
I have been told to add a little heat to my fermenter as it is sitting at a low 22 to 26 deg c.
The idea is to add a 100 watt aquarium heater to the liquid to aid yeast activity...
However, i am concerned that the heater will be of little effect due to the lack of constant movement of the mash.
Is it a good idea to put a small hole in the top of the fermenter and, using an air pump from an aquarium pump a small volume of air into the bottom of the ferment to create a constant stream of large bubbles to lift from the bottom to mix the mash?
