Advanced Nutrients Core Additives Compared: Voodoo Juice vs Big Bud vs Bud Candy vs B-52, Cost per Gallon by Size
Advanced Nutrients Core Additives Compared: Voodoo Juice vs Big Bud vs Bud Candy vs B-52, Cost per Gallon by Size
Advanced Nutrients sells additives in jugs from 1 liter to 23 liters, and the label price tells you little. A $39 jug and a $517 jug are the same product at very different costs per gallon of feed, and the four core additives do not cost the same either.
This guide uses the 2 mL per gallon dose stated in each product listing to turn jug prices into a cost per gallon of feed, for Voodoo Juice, Big Bud, Bud Candy, and B-52 at every size we carry. For how Big Bud compares to the newer formula, see our Big Bud vs 8th Generation guide, and for the other microbial products, our Hydroguard vs Voodoo Juice vs Tarantula comparison.
The 30-Second Answer
Cheapest per gallon: Bud Candy at $0.018 at 23L. Most expensive: Voodoo Juice at $0.079 per gallon at 1L. A flower gallon: Big Bud, Bud Candy and B-52 together cost $0.098 per gallon at the 4L size. The catch: the 23L saves a lot per gallon, but only if you will use it.

What Each One Is For, Per the Listings
Voodoo Juice is a beneficial microbe root inoculant for early veg and after transplants. Big Bud is a phosphorus and potassium bloom enhancer, used as a pulse in week 3 of flower. Bud Candy is a carbohydrate supplement run through flower. B-52 is a B-vitamin booster run through veg and flower. The listings describe all four as the core additives for the Sensi base, each at 2 mL per gallon, and the timing differs, so the cost of a feed changes by week. In a week 3 flower feed, that means Big Bud, Bud Candy and B-52 together: $0.124 per gallon at 1L jugs, $0.098 at 4L, and $0.075 at 23L. Base nutrients are priced separately. Size pays off: going from the 1L to the 23L cuts the per-gallon cost by 41% for Bud Candy, 35% for Big Bud, 42% for B-52, and 43% for Voodoo Juice.
What the Listings Leave Out
The listings give a dose and a timing, but not a shelf life, a mix compatibility chart, or the cost of the base nutrients. The Voodoo Juice 1L and 10L are out of stock right now, and the 4L has one unit, so the 23L is the size that is available. Ask us before you plan around a size.
Before You Buy
Check three things: which additives your program actually calls for, the size you will finish before it ages, and stock. Start with the smallest jug that makes sense for your room.

Frequently Asked Questions
Which Advanced Nutrients additive is cheapest per gallon?
At the listed 2 mL per gallon dose, Bud Candy is lowest at every size: $0.031 per gallon at 1L and $0.018 at 23L. Voodoo Juice is highest, at $0.079 at 1L and $0.045 at 23L.
Do I need all four?
The listings call them the four core additives, but they are used at different times. Per the listings, Voodoo Juice is for early veg and after transplants, Big Bud is a week 3 flower pulse, Bud Candy runs through flower, and B-52 runs through veg and flower. Skip what you don't need. Ask us before you buy all four.
Is it worth buying the 23L?
Only if you will use it. The 23L is 41% cheaper per gallon than the 1L for Bud Candy and 43% cheaper for Voodoo Juice, but that is a lot of product to get through, and the listings don't state a shelf life. Buy the size you will finish.
Does this include my base nutrients?
No. These costs are for the additives only. Base nutrients are separate, and the additives are added after the Sensi base per the listings.
Why is Big Bud only a week 3 pulse?
That is how its listing describes it: apply it during week 3 of flower, then stop, and don't run it through the whole bloom. That keeps it a small spend per grow even though its price per gallon is mid-range.
What about Piranha and Tarantula?
The Voodoo Juice listing says Voodoo Juice covers the large majority of the microbial benefit on its own, and that Piranha and Tarantula are additional microbial products. We didn't compare them here.
Is the price I see the price I will pay?
These are the prices on our product pages. The listings do not state shipping, so ask us about freight on larger sizes.
This article is general information, not agronomic advice. Doses and timing come from the product listings, and costs are for the additives only. Prices and stock reflect ModernFarms' live catalog as of November 7, 2026. We don't upsell, and we'd rather you buy the size you will use than the biggest jug.
