Make the brine by mixing uncholrinated water and sea salt together. Do not heat. Stir until most of the salt is dissolved.
Rinse cucumbers and cut off both ends. Slice into Spears.
Split the mustard seeds, dill seeds, dill springs, peppercorns, and garlic equally between the jars. Then pack the cucumbers into the jars.
Top with a grapes leaves if you have them and fermentation weight. Pour the brine into the jars ensuring the cucumbers are submerged.
Finally cover with a water lock lid, pickle pipe, or cloth or lid covering. You can also use the ziplock bag method (see notes below).
Ferment in a cool, dark place for 3-5 days. The longer you ferment them the more sour they will become.
When the pickles are ready, cover with a lid and store in the refrigerator. These pickles are most cruchy when used within 3 months but will keep for up to a year.
Notes
Ziplock Bag Method: You can fill a ziplock bag with liquid (like water or more brine), seal it tight, and place it on top of the ferment. This is a good method if you don't have special fermentation equipment. Use a heavy duty ziplock bag to make sure leaks are unlikely to happen.
Use a natural salt without additives
Cloudy brine is normal and happens when lactic acid is produced.
You may see scum on the top, it's generally harmless.
