I am not knocking the hi tech but to me it is too much work.
People were going #2 thousands of years before toilet paper, the manufacturing of said paper is hi-tech, and using it is more work than not. It may just be me... but that little extra work going hi-tech is definitely worth it.
Using the proper nutrients, stirring and looking after the ferment for a week or two is about the same amount of effort as wiping your ass for two weeks. But if you can't be bothered to do more than throw yeast in whatever you're fermenting... why are you here? You can, of course, throw together batches from whatever you have on hand...
Will it be drinkable? Maybe.
Will it be good? Flip a coin.
Will it be great? About as often as you can hit the bulls-eye on a dart board at
15 yards.
It looks like you've got your ways set, and it seems like you think there is no point for you to better yourself, your techniques or your brews... in which case You have all the info you need, if it's got available sugar throw some yeast in and you're done. Personally it's not the way to I'd do things... even if I were to do a show mead with no nutrients, I'd still be measuring my starting gravity and tailoring it to my yeast.
There is nothing we can do to help your ferments along without detailed info, a hydrometer reading chief among them. So, Yes, you can throw things together but without a little time and effort on your part giving us detailed information... there is very little we can help you with if things go wrong.
