StoneSkin 0-0-5 Limestone City Nutrients

Price range: $9.99 through $259.99

StoneSkin is our go‑to silica additive for growers who want structure, not struggle. Potassium silicate slips right into the plant’s cell walls, helping it stand straighter, handle heat, and support bulky flowers without snapping.

Cleaner growth, better water efficiency, and fewer environmental stress headaches — indoors or out. One simple weekly dose makes a huge difference.

Meet StoneSkin 0‑0‑5 — the potassium‑silicate boost that basically hands your plants a suit of armor. Stronger cell walls, sturdier stems, better heat and drought tolerance, and way less stress during heavy fruiting.

It’s the same silica used to strengthen concrete, but tuned for plants. Use it in any medium, any system, any stage. If you want taller, tougher plants that hold weight without folding, this is the one.

If your plants could ask for one thing to feel sturdier, it would be silica — and StoneSkin delivers it in the most absorbable form.

• Stronger stems and branches • Better resistance to pests, disease, heat, and drought • Improved flower and fruit production • Works in soil, coco, hydro, and won’t clog emitters

Think of it as structural support from the inside out. A little StoneSkin goes a long way.

Description

StoneSkin is a potassium silicate additive that helps your plants build stronger, sturdier cell walls. Think of it as a natural “armor” that supports your plant through heat, drought, pests, and disease — indoors or outdoors.

Silica is one of the most overlooked plant supports. When your plant absorbs potassium silicate, it reinforces its structure from the inside out. This lets the plant stand taller, hold heavier fruit and flowers, and use its energy for growth instead of constantly fighting environmental stress.

What StoneSkin Does:

  • Strengthens plant cell walls
  • Helps plants handle heat, drought, pests, and disease
  • Improves water‑use efficiency
  • Supports heavier fruit and flower production
  • Encourages sturdier stems and overall structure

Why It Matters:

A plant with strong cell walls:

  • resists stress more easily
  • stands straighter and sturdier
  • supports bigger yields
  • grows more vigorously in all environments

Potassium silicate is the most ideal form of silica for plants — easily absorbed, highly effective, and even used industrially to strengthen concrete. It’s a simple way to improve structural integrity at every stage of growth.

How to Use It:

  • Mix 1 mL per litre of water
  • Use once per week or with every feeding
  • Suitable for both vegetative and flowering stages
  • Works in all growing media, including hydroponics
  • Safe for drip irrigation and aeroponic emitters
  • Can also be used as a foliar spray

What’s Inside:

  • Potassium silicate (source of soluble silica and potash)

Manufactured in Kingston, Ontario by EZ‑GRO.
