**I have personally tried this numerous times with excellent results.. it has always worked for me without any probs. The end result for me each time I have made this type of hash has been excellent and mind-boggling!** Follow these steps in order to make your very own potent stash of ISO Hash. Step 1: Take all of your trimmed leafy material and crystally non-stem material that you have trimmed from buds you have harvested and or smoked. Step 2: Put all that material (greenery) into a mason jar (about 1/2 full) and put into freezer over night to freeze. (Be sure to use 91% ISO Alcohol. You can get it from Cosco's; Walmart; or Walgreens) Step 3: Pour ISO into jar until greenery is well covered (about 3/4 full). Shake jar vigorously for about 30-60 seconds. Step 4: Now strain the liquid using coffee filters into a pyrex pan. Step 5: Now for the last step.. Let the ISO evaporate for about two or three days; then...using a sharp razor blade.. start scraping off the dried material (hash).. and enjoy!!! Happy Holiday's Everyone. Peace.
