I am not totaly sure what you mean by water cure. But I will detail my procedure for mold if you like.
1. Fill two buckets with warm water, add a cup of baking soda and a squeeze of lemon juice to the first bucket.
2. Chop the plants so that you have section of stem for a grip to shake them in the buckets.
3. Dip in first bucket vigorously, repeat in rinse bucket.
4. Once it's all gone through, repeat process with a fresh rinse bucket once more.
5. Air dry by laying it out on a bed or table in a single layer with good airflow, add a fan if the air is still.
What does this accomplish you ask?
1. The baking soda and water mixture absorbs bug shit, free mold spores, dust, and other materials too small to see from the buds.
2. It does NOT dissove trichomes or oils.
3. This will remove most spores and most any early infestation, if the mold has progressed to where you can see it, especially if it is dark colored, you must cut that section out and dispose of it. Moldy bud is very bad for the lungs.
4. This will prevent mold during curing on parts of the plant that did not erupt with proper mold, or that were mold adjacent without symptoms.
