tried this twice this winter out of pure laziness. Both times was hard to start fermentation with dry yeast but both turned out great. I am in Iowa so worked in winter would not try in summer. both beers are good drinkers.
On my current control box I pull my 110 power off one of the main legs and it works great. thinking out loud on future project could I use a L14 style connector and use one of the prongs to carry a separate 110
