Temperature change? If your fermenter cooled off significantly you could get suck back.

No, i had a strand of lights around it the whole time. Maybe its just done? It liked being over 80 degrees (off the thermo scale). I unplugged the lights a few days ago and within an hour fermentation had slowed significantly because of the temperature drop so i plugged them back in.

That is pretty high of a ferment temp. If it dropped back down to ambient temperatures, then you will definitely see a slowed fermentation, perhaps combined with a change in humidity caused the suck back.

Maybe your fermenter was just puckering.

I know cranberry juice makes me pucker.

Guess number two; it was so warm the vodka in the airlock evaporated.
Guess number three; someone in your house needed a drink really bad.

so i just tried some, and its ****ing amazing. BUT, the hydro reading is like 1.035. I dont understand how its still that high after fermenting like crazy for many days. Do you guys think i killed off the yeast with the temperature? Should i pitch another? is there a reason why the SO4 would have given up with cranberry juice?

let me know what you guys think I should do

When you take a reading, make sure to dunk than hydro down into the beer a couple times to knock off any CO2 that may be clinging. Those CO2 bubble like to gather on your hydro and cause it to float.

so i pitched another packet of yeast, and added another cup of sugar. I guess i should have added the cup then waited to see if anything happened before pitching another packet. oh well, its bubbling
