I always feed once a day, stir twice a day. First day feed only sugar, next day sugar & ginger. I'm not sure about starting with that much sugar. Always use 2 big spoons of ginger, 2 big spoons of sugar, 2 cups of water to start mine. Definitely at least stir it two times a day. Worst case, you have to throw it out & learn something, right?

Exactly! So far it seems to be healthy and active, but next time I'm gonna use the ratio you mentioned.
I've been stirring it once a day when I feed it but will probably stir it again tonight too.
You want to make sure there is enough sugar for the yeasts et al. More ginger shouldn't be necessary. I would taste it, and judge the sugar levels that way. If it is getting sour, then take a small portion out and put that in fresh sugar water. If it's still sweet, then I wouldn't feed it.
Ah yeah, makes sense.
I've been feeding it a teaspoon of sugar and ginger since it started, and its starting to foam and bubble pretty nicely. I think I'll taste it tomorrow and if it tastes very sweet, I'll stop feeding it for a couple days.
So far so good, the aroma has gone from a very strong ginger smell to a yeasty ginger smell so it seems to be working very well.
