How do I mix Jack's 321?


We get a lot of questions asking about how to properly mix our Jack's 321 program (and how to know if something isn't mixed properly). Our very own "Wild Bill" Cody is here to give you the definitive mixing lesson straight from the JR Peters Laboratory.


Our Jack's 321 program is here to help you get your grow operation performing at optimum levels. To further dial in your hemp, cannabis, or other controlled environment crops check out our grow schedules page.


And Remember It's:

- 3.6 grams/gallon Part A (5-12-26) and dissolve then add

- 1.1 grams/gallon Epsom Salts and dissolve completely then add

- 2.4 grams/gallon Part B (Calcium Nitrate)
