Whole Bag Formulas
3-2-2 and 4-3-3 are our whole-bag formulas. Whole 25lb bags are added to 55 gallon drums for consistent stock concentrations.
3-2-2 is the best method for most facilities, as it uses equal volumes of water. You mix three 25lb bags of Part A into 50 gallons of concentrate, two 25lb bags of Part B into 50 gallons of concentrate, and two 25lb bags of Bloom into 50 gallons of concentrate.
4-3-3 is best for fertigation equipment requiring lower injection ranges and/or more concentrated stock solutions. You mix four 25lb bags of Part A into 53.5 gallons of concentrate, three 25lb bags of Part B into 60 gallons of concentrate, and three 25lb bags of Bloom into 60 gallons of concentrate.
With both methods, you can validate the mix with our Validation EC charts and get the right results every time. Both methods create three stock solutions that can be injected at equal rates for our full-cycle "Stack" recipe.
