Jacks 321 to lazy to measure guide

So i ran my 1st grow of mephistos autos without the time consuming task of measuring 3.6g a 2.4 g b 1.2 E. I just filled a container with 1.5 cups A and .5 cup E shook well and a smaller B container.
Just under 1 tsp is 4.8 g A+E
Exactly 1/2 tsp of B is 2.4 g
Results plants grew great even if they had slightly varied nutrients heres my transplant mars hydro auto and my tent and yes they’re over 5 feet


Awesome idea! Killer ladies!! :heart_eyes::heart_eyes::heart_eyes:


I believe there is a recipe to make a liquid concentrated form of Jacks.

What size containers. Gallon and 1/2 gallon?

The measurements of Jacks is very forgiving.
In a gallon I mix 1/2 tsp of A and after is it fully dissolved 1/2 tsp of B.
I Don’t bother to try to level the teaspoon either. Sometimes give it a little extra a by letting a rounded tsp go in. No Epsom anymore. A little extra pat A and its unnoticeable.


I just mix theym up in little sour cream contIners but its up to you
