Re: EM and Activation?

Direct sun exposure, or in a dark box exposed to the sun (some say no direct sun, some say it increases the phototrophic bacterias number).

Maybe putting it in how water is an isolated box (such as a big enough lunch box).

It's getting hot here, I'll have to find another way than using the radiators.

Keep in note that even at room temp, the fermentation produces some heat.
