Wash and scrub cucumbers well. Cut off the ends, if you want the pickles to ferment faster.
Soak the cukes in cold water for at least 30 minutes.
While the cucumbers are soaking, prepare other ingredients: pour boiled hot water into a jug or jar, add 1 tablespoon salt and stir to dissolve. Wash the dill stems, peel and slice the horseradish.
Wash a large glass jar (2 qt) and its lid thoroughly with hot, soapy water, then rinse well. Carefully pour boiling water into the jar (and over the lid) to sanitize it. Let the water sit for a minute, then discard it and allow the jar to cool slightly before using.
Place the cucumber in the jar, layering dill, garlic, horseradish and bay leaves. I start with putting the cucumbers in vertically. They should be quite tight for best results.
Once everything is in the jar, pour in the salty water. It can be hot, at room temperature or cold. I like to add hot water because it shorterns the fermentation time. You may not need the entire amount which is ok. The cucumbers should be completely covered though.
Place the lid on the jar without tightening it completely to allow air and fermentation gases to escape. You can also cover the jar with a clean cloth secured with a rubber band.
Place on the kitchen counter or a warm spot for at least 48 hours to ferment. If your jar is very full, place it on a plate or a bowl to catch any juice that may come out (not likely but it can happen and ruin your countertop).
Once your pickles are done, enjoy right away or close the lid or transfer to a different glass container (with the brine) and place in the fridge.
