I am building a fermentation fridge based on an STC1000. Clearly if I had a heating side to it I would no doubt be better able to control the temperature; but I am not sure whether the heating element that I'm getting will be in in time for my next brew and I just got to thinking ... do I really need a heating element?
My point being that given that in my own circumstance the fridge would be located in a room temperature environment surely there's no real need for a heating side as the temperature if it gets too low will just heat up eventually ... probably slower than ideal, granted.
but my question is this: — Would the heating side be something which is "ideal" rather than something which is "necessary" in a scenario where the fridge is in an aprox 20C environment and I'm using US05 yeast ( which doesn't need high temperatures and has a reasonably wide temperature range), and given the fact that I'm reasonably new to homebrew so at this point I'm aiming more for good beers than great beers; to quote John Palmer ?
— and if I'm wrong about this could this please be explained.
