You track your EC. You check your pH. But do you know your true cost-per-mixed-gallon?
If you’re not tracking that number, you’re not in full control of your inputs—or your outcomes.
The Hidden Cost of a Guess
Every gallon of feed you mix is a decision. And whether you’re running a small veg room or a full flower facility, those decisions add up. Most growers don’t calculate their actual cost-per-gallon. That leaves money on the table—and introduces uncertainty into your system.
If your nutrients aren’t fully soluble, if your stock tank clogs, or if your dilution rates are bloated, you’re paying for it whether you see it or not.
How to Calculate Your Cost-Per-Mixed-Gallon
You don’t need software to do this. Here’s the basic formula:
- Find the cost per milliliter.
Divide the total price of the bottle by how many mL are in it.
Example: $20÷ 4,000 mL = $0.005 per mL - Multiply that by your feed rate per gallon.
Example: 8 mL per gallon × $0.005 = $0.04 per gallon - Repeat for each part of your feed program.
Add the cost-per-gallon from each part to find your total. - That’s your true cost-per-mixed-gallon.
Multiply by how many gallons you mix weekly to get your monthly nutrient spend.
Run the Math. Then Do the Math.
Once you’ve calculated your own numbers, ask yourself:
- Are you spending more than $0.14 per gallon?
- Are your stock tanks building up sludge or clogging filters?
- Are you running multiple bottles just to stay balanced?
If the answer is yes, Drip Hydro may be the upgrade you’ve been looking for.
Why Growers Switch to Drip
- POWDERS: $0.05–$0.07 per gallon
- FLUIDS: $0.10–$0.14 per gallon
Both systems are designed to work clean, stay stable, and scale efficiently—with full solubility and cannabis-specific formulation. Growers switch because it saves them time, money, and guesswork.
You don’t need to compromise performance to gain control—you just need the right system behind you.

Takeaway: If You Don’t Track It, You Can’t Optimize It
Knowing your true cost-per-mixed-gallon is one of the fastest ways to increase your margin and improve consistency. Whether you’re feeding five plants or five rooms, the math tells a story. And that story either costs you—or saves you.
If you want to grow fire at scale, start by knowing what’s in your tank.
