The problem with that is all veggies are different. Cabbage ferments easily and seldom fails even at a 2% salt by cabbage weight. A pepper ferment at just 2% has a much higher chance of failure. Jump upto a 4% brine and the chance plummets. Add a culture starter like Caldwells and the chance is even less.
The basics are
Least amount of air space needed in the container. Lacto B needs no oxygen at all.
Sterilize everything just like wine making.
Keep your veggies submerged. I use glass weights when using Mason/Ball jars. A cabbage leaf under the weights stops anything getting past them. Anything that floats increases the chance of mold.
Start with low pH bottled water when possible. I use Niagara brand because it has the lowest pH of any i can find and its cheap.
Use good salt with no iodine added. High mineral content is nice if using distilled/purified bottled water.
One of the best thing you can do if using Masons are the vacuum lids. They have a pump to remove air and they vent as CO2 builds up. Guys have great success with these.
