Making Sauerkraut

I started on December 19th with one 4.7 pound green cabbage purchased from the Farmer's Market for two dollars. I chopped it up into long shreds and placed it in a large metal bowl, added sea salt and mixed it together, purposely bruising the cabbage in the process to get it to begin releasing water. I read in several places online that the accepted ratio of cabbage to salt is 5 pounds to 3 tablespoons, so I used a little less than 3 tablespoons. I then packed the cabbage and salt mixture into a glass fishbowl (the largest glass container I could find). I wasn't satisfied with the amount of brine that was created by the cabbage juice and salt mixture, so I mixed more sea salt into some distilled water and added that (using the amount of salt that I thought would be enough to keep bad germs from growing, but not so much that it would taste too salty to eat). I put a bowl on top of the cabbage to raise the brine level above the cabbage, covered the fishbowl with plastic wrap and a rubberband, and hoped the microbes would make me something tasty. Following are daily notes on its progress:

One day later: ~68 (degrees Fahrenheit). Cabbage-y smell. Bubbles that look like spit on the surface of the brine. I covered the fishbowl with a t-shirt to keep it dark (read somewhere that it should be dark).

Two days later: ~66. Bubbles this morning. Very strong sulfur smell. Tastes sweet and salty (sweet cabbage, salty salt).

Three days later: Tastes less sweet. Beginning to smell a hint of sour. Water is a little cloudy.

Four days later: ~62. Smells much more sour, still bubbling.

Five days later: ~64. Seems to be bubbling less. Tastes quite sour.

Six days later: ~66. Seems to have stopped bubbling altogether.

Eight days later: ~63. Fragrantly sour. Time to start eating it.

I'm surprised by how the sauerkraut no longer tastes salty. I know there's a lot of salt in it, but the sour flavor must be masking it. Also, the smell produced as the bubbles were released was very strong and smelled like sulfur. I read on one site that if your kraut smells bad, you shouldn't eat it. Well, that certainly smelled bad but I stuck with it and I think my finished product is fine (it tastes good and I'm not sick). I wonder how many people have started making sauerkraut but threw it out thinking something had gone wrong.

Pictured at the top is my sauerkraut in the fishbowl and below is the same fishbowl covered by a shirt, with some of the kraut that I transferred to a different jar. The jar is in a plastic tub so that when I push on the other jar that fits inside of it to push bubbles out of the cabbage, the brine doesn't spill onto the carpet. The other object is a thermometer.
