Packed with a B-Vitamin complex, kelp, and an essential nutrient blend, B-52® serves up a robust menu of ingredients for unlocking the true potential of your crops. Vitamin B1 plays a key role in creating optimal conditions and supporting photosynthesis and respiration, while fending off potential damage from abiotic environmental stressors. Kelp strengthens the root zone and fortifies plants from abiotic stress for uninterrupted growth. This premium biostimulant is a must-have for strengthening stalks, stems, and buds, so your plants remain resilient throughout both the grow and bloom phases.

  • Kelp is an all-organic powerhouse at optimizing soil changes for strong, vigorous growth
  • Readily available B-vitamin complex protects against abiotic (environmental) stressors
  • Humic acid stimulates microbial activity in root zone, assisting in nutrient uptake

B-52® is specially designed for use with diverse hydroponic growing media and all continuous liquid-feed growing systems such as aeroponics, drip irrigation and emitters, NFT, flood and drain, and deep water culture.

ATTENTION: B-52® is completely compatible with all pH Perfect Base Nutrients as well as with all non pH Perfect Base Nutrients and supplements and all competitors Base Nutrients and supplements.

NOTE: At Advanced Nutrients, we do not use paclobutrazol, daminozide, or any other banned plant growth regulators in our products.

B-52® — Why Experts Call This the Most Important Thing  You Can Feed Cannabis Plants Besides Your Base Nutrients 

Bloom boosters. Root expanders. Crop substrates . . .

Ask any grower, and they’ll gladly share the importance of feeding your plants the right nutrients.

It’s why our team of experts has spent years developing best-in-class products . . .

From next-generation base nutrients to the most popular bud bulking biostimulant on the planet.

And it’s why we’ve engineered a product to optimize plant potential at every phase of the game.

There’s one product, however, that separates premium cannabis from the rest . . .

A must-have product for serious growers who want to be the master of their grow room environment.

Now, in a moment, we’re going to tell you exactly what that product is, and what you can expect from using it.

But first, you’ve got to understand . . .

The Ugly Truth About Raising Bud Weight 

Because here’s the thing…

It’s a known fact that your plants can sense exactly how much bud weight they can hold, based on the strength of their stalks and branches.

When was the last time you saw a serious strength athlete with a massive upper body and ten-cent chicken legs?

Your cannabis plants are the same way.

The stronger their stalks, the greater the potential for bigger buds.

See, plants with larger stalks can transport more water and nutrients to budding sites…

Equipping them with the robust essentials they need to pack on weight throughout the bloom phase.

There’s just one big problem…

Your crop doesn’t always have the luxury to focus on building that strength.

Sometimes, combatting abiotic environmental stressors becomes the first priority.

And when this happens, your plants are in “survival” mode.

You see, these stressors force your garden into course-correction mode. 

Things like…

  • Transplant shock
  • Over or under-watering
  • And rapid temperature changes

… All distract your plants from rock-solid development and explosive flowering.

No doubt about it…

The more effectively you can safeguard your plants from these stressors, the easier it will be for them to focus on what matters, and what you really want…

Vigorous vegetation and robust floral production.

Which is why…

You Must Fortify Cannabis with Optimal Nutrition

And that starts with Kelp . . .

A plant-potentiating powerhouse loaded with more than 72 trace minerals.

Consider Kelp Mother Nature’s gift to growers.

It can help . . .

  • Increase plant resistance to a wide range of abiotic stressors and weather
  • Expand your garden’s root mass, increasing nutrient uptake
  • Support photosynthesis and respiration, invigorating your harvest
  • Create optimal conditions for strong, uninterrupted plant growth

What’s more, Kelp contains . . .

Vitamin B1, Your Best Defense Against Abiotic Stressors

Now, remember, we all want the same thing…

Plants that focus their energy on building sturdy stalks and fat, flavorful buds.

And to keep their attention where it needs to be, you MUST support their ability to fend off challenges.

It’s why top growers rely on B-52® through both their grow AND bloom phases . . .

Because studies show it can help fight stressors like, chilling, drought, ozone, and salinity.

So, no matter how harsh the environmental conditions of your grow room are…

You’re still giving your plants their best shot at maintaining peak performance.

In fact, it’s the Vitamin B1 in Kelp that helps create optimal conditions for supporting photosynthesis and respiration.

And it’s why we’ve made it possible for you to . . .

Transform Your Crop With this One Simple Addition

Kelp and a B-vitamin complex are great.

But here’s the thing…

Cannabis needs a broad spectrum of plant-potentiating ingredients if you’re going to yield high-value harvests on repeat.

We engineered our premium biostimulant B-52 to go above and beyond the benefits you get from just Kelp and Vitamin B1.

You’re also getting humic acid, helping to increase nutrient uptake from the rootzone.

Humic acid is universally adored by seasoned growers who hit the mark on their harvests, every single time.

Just imagine protecting your plants with premium insurance against crop loss… Simply by adding one product to your nutrient line.

For high-performing growers, the choice couldn’t be clearer.

Over time, components within the nutrients settle on the bottom of the bottle. When you pour a bottle without shaking it, you can potentially be pouring out an unbalanced solution. Shaking up the nutrient bottle ensures you are pouring the right blend into your reservoir, giving your crops the nutrition they need.

Usually, it’s not a problem. But some products are incompatible with each other and can damage your plants when they’re used together. For example, bloom boosters with high PK numbers or low-grade silica products can destabilize your nutrient mix and cause nutrient lockout.

Nutrient manufacturers design their products to be used with each other. In doing so, they include specific portions of each nutrient in each product, so crops receive the right nutrition through each stage of the grow cycle. When you stick with one manufacturer, you don’t have to worry about inadvertently destabilizing your nutrient mixture. One example of why you need to stick with only one manufacturer’s products is Advanced Nutrients’ pH Perfect line. These products are designed to keep your crops’ root zone within a specific pH range. When you use them alongside products from another manufacturer, we can’t guarantee your root zone will maintain its optimal pH level.

Advanced Nutrients has spent many thousands of man-hours developing a technology that automatically balances your pH for you — putting it in the “sweet spot” and holding it there for one week.

And the technology is so “smart” that it can account for many of the aforementioned variables in your grow room. Our proprietary pH buffering agents and stabilizing mechanisms became the foundation of a new system aptly called pH Perfect® Technology. Learn all about it here.
