Safeguard your grow with Rhino Skin®, a potassium silicate biostimulant that strengthens your high-value plants. We carefully selected the most soluble forms and bioavailable forms of this naturally thick and solid element for your high-value crops. The result is a next-generation silicate that increases stalk rigidity, providing a sturdy foundation that can support the weight of heavy flowers.

  • Increases resilience to challenging environmental conditions
  • Optimal ratios of potassium to silica decreases risk of contamination
  • Strengthens plants so they can support an explosive bloom phase

Rhino Skin® 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: Rhino Skin® 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.

Rhino Skin® — The ONE Thing You Need to Strengthen Your Crop and Support Massive Bud Weight 

There is a simple formula for growing bigger flower . . .

The stronger your foundation, the larger your yields.

Because here’s the thing . . .

When you fortify your crop’s stalks, stems, and branches . . . 

They’re powerful enough to hold up potent, weightier buds. 

Now . . . 

There’s one ingredient your cannabis plants must absorb if you want to build a strong structural foundation . . . 

And Safeguard Your Plants from Abiotic “Environmental” Stressors! 

The ingredient is silica . . . 

And it’s something every expert grower swears by to keep their garden vigorous, resilient, and ready to flourish.  

You see, silica is a thick, solid element. 

And when you deliver it to your crop, it cements the spaces between cell walls . . .

And even coats the cell walls themselves! 

Which is why when you add silica to your garden, you’ll . . .

  •   Fortify your cannabis plants, protecting them from heat, drought, disease, and other abiotic “environmental” stressors
  •   Help stalks and stems to stand up straighter, so they can easily support heavier, bulkier flower
  •   Shield your plants with a coat of armor, so they can focus on producing bigger, lusher yields instead of expending energy on day-to-day survival 
  •   Help to prevent excessive moisture loss through the plants’ cell walls

No doubt about it, when you enrich your garden with silica, they’ll have the strength they need to spoil you with massive rewards come harvest time. 

In fact . . . silica is so crucial to your garden’s vitality . . .

Cannabis Literally Evolved to Absorb It! 

Because without silica . . . 

You risk growing a weak, brittle garden that cripples under the pressure of changing environmental conditions. 

However . . . 

Despite how insanely beneficial silica is for your crops . . .

It remains almost completely absent from hydroponic fertilizers and root zone media! 

Now . . . 

Could you imagine starving your garden of a proven shield of defense and a powerful boost of stalk-strengthening properties . . .

Of something they so desperately need to thrive, they evolved to intake it as part of their cell walls?

The reality is, once you understand silica’s potential to safeguard your crops and support the development of hearty, weightier buds . . .

It becomes nearly impossible to consider growing without it! 

And keep in mind . . . 

Even if silica has been included in your fertilizer . . .

Not Every Silica Biostimulant Will Yield Big Results

Because remember . . . 

Silica is thick. It’s so thick, in fact, it’s the main ingredient in sand. 

And make no mistake, that’s what makes it the ideal candidate for shielding and strengthening your crops. 


Getting such a solid element to dissolve in water, and become readily available to your garden, is NOT an easy feat. 

What’s more . . . 

Too Much Silica Can Harm Cannabis in the Long Run!

Which is why you must feed it to your plants at optimal concentrations and ratios…

IF you want a successful silica biostimulant to do wonders for your crops. 

Our scientists knew this…

And we ran countless experiments to identify the best form of silica for your plants.

What we discovered is the ideal form of potassium silicate…

In the exact ratios your plants need to fully absorb the elements…

AND reap the countless benefits of this stalk-strengthening powerhouse

The result is…

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.
