The potassium silicate supplement for cell wall strength and stress resistance. A useful, case-dependent addition.

Rhino Skin is Advanced Nutrients' silica supplement, a potassium silicate formula that strengthens cell walls, supports sturdier stems, and helps plants resist heat, pest, and environmental stress. Silica is a genuinely useful supplement for cannabis, and Rhino Skin is AN's entry in the category.

One honest note: potassium silicate requires careful mixing. Add it to your reservoir first, before any other nutrients, and stir thoroughly, because silica products can raise pH sharply and can react with other inputs if added in the wrong order. Monosilicic acid silica products mix more easily since they don't carry the same pH-spike sensitivity, but both deliver real silica benefit.

Key Benefits

  • Potassium silicate for cell wall strength and sturdier stems
  • Supports resistance to heat, pest, and environmental stress
  • Run throughout veg and flower
  • Useful, case-dependent addition

How to Use

Add Rhino Skin at 2 mL/gallon to your reservoir FIRST, before any other nutrients, and stir thoroughly. This mixing order matters with potassium silicate to avoid pH spikes and reactions. Run throughout veg and flower. Spot-check pH after mixing.

INFORMATION QUESTIONS

FREQUENTLY ASKED QUESTIONS

What is Hydroponics?

Hydroponics is the science of growing plants without soil. The plants thrive on the nutrient-water solution alone. The growing medium merely acts as a support for the plants and their root systems while the solution passes freely. The growing medium, if any, is totally inert.

What types of plants grow best hydroponically?

Anything can be grown hydroponically, but some plants prove to be more space efficient. Some plants we suggest are tomatoes, sweet peppers, hot chilies, lettuce, spinach, squash, cucumbers, broccoli, beans, snow peas, herbs and flowers of all types.

Can you REALLY get better yields/quicker growth?

Absolutely. The plants, when receiving everything they need, tend to be healthier, faster growing and generally more productive. You can expect 30% faster growth with many crops.

What are the watering cycle timelines hydroponic systems?

Once the reservoir is filled with nutrients, it is time to put your hydro system to work! The ease of hydroponics is automation – automation is achieved by putting the pump on a timer according to your watering needs. The watering cycle depends on growth stage, growing medium and hydroponic system. In an ebb and flow or drip system with rockwool as the medium, seedlings, clones and plants in the early vegetative stage require watering only once a day for 15-30 minutes (twice a day for higher temps). Mature, flowering and fruiting plants require a heavier feed and can be fed once a day for 30 minutes (twice a day for higher temps). Typically soiless mixes and coco fiber can be watered for about 15 minutes twice a day, and can be adjusted for heavier feeding during the flowering and fruiting stage or higher temps. ViaStone, Hydroton, Grow Rocks, and Silicate mediums need to be watered more frequently – a constant drip for drip systems, and about 15-30 minutes every 3 hours for ebb and flow systems and can be adjusted for heavier feeding during the flowering and fruiting stage or higher temps. Aeroponic systems require frequent watering cycles; 30-60 seconds every few minutes or a constant spray.

What do I need to test pH? How do I test pH?

pH has a range from 0 (acidic) – 14 (alkaline), with 7 being neutral. A proper hydroponic pH range is between 5.5 to 6.2 for most hydroponic crops. For specific crop pH, check out our Plant Guide. pH must remain within the proper range for good plant health, disease resistance, and proper nutrient uptake. pH is maintained by adding pH Up and pH Down to the nutrient solution. For more information, see the Testssection of our site.

How will the flavor compare to my outdoor grown, organic produce?

The taste may be even better! This is simply due to the fact that the hydroponically grown plants are getting everything they need, when they need it. Don’t be fooled by “hot house” produce grown commercially. The grower’s primary concern is shipability and storage, not flavor. When you grow your own vegetables at home, you can expect nothing less than excellent results. Plus, hydroponically grown produce has the added benefit of a longer shelf life.
