- Diamond Crystal Bright & Soft Salt Pellets, 40 lb. Bag
- 5 gal plastic Home Depot bucket (fill bottom of bucket 1/4 - 1/3 salt, then add water until bucket is half full).
After a day or two (and some occasional stirring), the salt pellets will have begun to breakdown and the water molecules will have become completely saturated with sodium to a maximum salinity of 26.3%. Add a squirt of Dawn dish washing liquid and stir. Put in HDX sprayer. Spray blackberry and watch it die.
Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 grams of salt per one liter (or kilogram) of water. The saturation level is dependent on the temperature of the water. At 20 °C one liter of water can dissolve about 357 grams of salt, a concentration of 26.3%.
