Piranha® is loaded with powerful fungi for maintaining a well-balanced, yield-boosting root zone. With the help of beneficial bacteria, these fungi break down nutrients into plant-available forms while feeding on waste secreted by the roots, resulting in ideal conditions for an uber-efficient rhizosphere. Add Piranha to your root mass expanders to give your plants the nutrition they need for building bigger biomass and lush flowers packed with essential oils.

  • Balances root zone, minimizing the risk of crop failure
  • Ectomycorrhizae expand the surface area of roots, improving nutrient absorption
  • Endomycorrhizal fungi penetrate root membranes, transporting nutrients into plants
  • Improves plant tolerance to abiotic (environmental) stresses

Piranha® 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: Piranha® 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.

Piranha® — The Weird Root Zone Powerhouse
Behind Maximum, Compound-Rich Yields 

Do you know what the earth would look like if the millions of beneficial fungi beneath the soil simply ceased to exist?

A dead, barren wasteland would greet us every time we went for a walk in nature.

And, no doubt, it wouldn’t be the abundant, bountiful world we want to live in . . .

So why would we force our plants to suffer through the same depressing, stark conditions?

Here are the cold, hard facts:

  • Hydroponic root zones are sterile. And without any intervention, they can do little to reward you with lush, heavy yields of highly potent flowers.
  • Fungi are essential warriors that maintain a robust and extensive root zone and increase the absorption of critical nutrients. They’re one of the most effective ways to unleash a vibrant garden packed with essential oils.
  • The better you care for your rhizosphere with beneficial fungi . . . The more likely you are to unlock bigger yields.

And it’s a little-known fact that without beneficial microbes, no plants would grow on earth.

To put it simply . . .

Your garden has its best chance at increasing compound-rich biomass when you replicate Earth’s soils.

It’s the way nature intended it.

So you can see why, for experienced growers, adding fungi to their root zone is non-negotiable.

Sure, they’re hidden, invisible, and too often overlooked in grows.

But don’t be fooled . . .

Your Root Zone Can Make or Break Your Next Crop Cycle

Because here’s the thing . . .

Fungi form a symbiotic relationship with the root zone.

And when you add nature’s genius back into your grow room, they’ll. . .

  • Transform nutrients into plant-available forms your roots can uptake . . . While feeding on organic waste so your rhizosphere stays clean and free of harmful debris
  • Sheathe the root tips and build mycelia, extending the roots so they can capture and solubilize locked-up nutrients
  • Penetrate the root membranes, effortlessly transporting critical nutrients across the barrier and into your plants
  • Increase plant tolerance to changes in water, the growing medium, or the environment

. . . Just to name a few of the benefits your crop enjoys when you add beneficial fungi to your routine.

So just imagine . . .

If you could suddenly walk away with your biggest yields yet . . .

Simply because you didn’t neglect your garden’s root zone!

Even our most skeptical growers become hardcore fungi converts the moment they see vibrant green leaves pitched at a 45-degree angle, reaching for the lights, just hours after their first feeding.

Keep in mind, however . . .

Not All Fungi Biostimulants are Created Equal

And many companies will choose the most cost-effective production methods . . .

At the expense of YOUR harvest!

In fact, it’s not uncommon to see incompatible strains bred in bulk . . .

Where skewed ratios can cause one microbe to dominate the others, rendering them useless to your root zone.

And just as concerning . . .

Some growers fall victim to generic strain names . . .

Which deceives you into thinking you’re getting the Ferrari of fungi, when you’re really driving home a Malibu!

Right now, if you’re using a generic biostimulant, you’re probably only getting a fraction of the benefits fungi can unleash to support a healthy, vibrant root zone.

Which is why . . .

Top Growers Rely on the No. 1 Beneficial Fungi Biostimulant on the Market

Backed by years of research and development conducted by the world’s sharpest microbiologists . . .

Piranha® is the ultimate solution for a well-balanced, flourishing root zone.

And we spared no expense in engineering this biostimulant to deliver explosive, yield-boosting results.

When you deliver Piranha’s fungi to your garden, you’ll . . .

  • Maximize root growth for optimal yields
  • Create a clean, well-balanced rhizosphere
  • Improve absorption of critical nutrients
  • Increase essential-oil rich biomass

And, even if that’s all Piranha included . . .

You’d still be way ahead of the game in enriching your root zone with nature’s innate genius.

But we didn’t stop there.

Because the world of microbes is as complex as it is inspiring . . .

Our scientists spent years studying the ways bacteria and fungi work together to support bigger yields.

Which is why . . .

We Also Engineered Piranha® with Bacillus mucilaginous…

A unique strain of bacteria that solubilizes phosphorus and potassium in your root zone.

In other words, your plants get more of these two essential macronutrients, and can reward you with heftier yields in return.

Now, you can use Piranha in conjunction with your other root mass expanders, Voodoo Juice® and Tarantula® (that’s what most of our growers do).

And when do you, you’ll enjoy the same sweet satisfaction as you would walking through the most fertile, abundant soils on Earth . . .

And relish the sight of a huge, lush canopy of potent, healthy flowers. 

A sizable, efficient root zone is a must-have for the serious cannabis grower.

Don’t wait to discover how much greater your yields can be.

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.
