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)
