NPK Industries NPK RAW Silica - 25 lb

Stronger Stems and Cell Walls From a Silicon Supplement - 25 lb Bag

Plants under heavy feeding and bright lights need sturdy stems and cell walls, and many nutrient lines do not cover silicon on their own. NPK RAW Silica adds silicon dioxide in a form that suspends in water, so you can mix it into your reservoir or feed water without changing your routine. The manufacturer lists its silicon dioxide content at 45%.

The 25 lb size suits growers who feed silicon every cycle across multiple plants or rooms. If you only want to trial a silicon supplement, a smaller bag may fit better; this size serves regular indoor growers and small commercial operations.

Key Features & Benefits

• 45% silicon dioxide — a concentrated silicon source per scoop.
• Suspends in water — flowable and suspend-able, so it mixes into feed water.
• pH neutral — it does not push your solution pH around, according to the manufacturer.
• Does not cloud water — your reservoir stays clear when you add it.
• Works with feeding programs — use it during vegetative growth and flowering alongside your nutrients.

Who Should Use NPK RAW Silica

Growers in hydroponic systems, soil, or other media who want to add silicon to a feeding schedule will find it useful. The 25 lb bag fits those who run several cycles or larger gardens.

Frequently Asked Questions

Q: What does silicon do for plants?
A: Silicon is commonly supplied to support stem and cell wall strength. NPK RAW Silica is intended for that purpose during growth and flowering.

Q: Will it change my solution pH?
A: The manufacturer describes it as pH neutral because it is a natural form of silicon dioxide. Still check your solution pH after mixing, as you would with any addition.

Q: Will it cloud my reservoir?
A: The manufacturer states it does not cloud water when added. It is flowable and suspends in water.

Q: Can I use it with my current nutrients?
A: It is intended to work alongside nutrient and feeding programs. Add it according to the label directions for your schedule.

Q: What does suspend-able mean?

Q: Where can I find safety information?
A: A safety data sheet is available from NPK Industries. Review it before handling and storage.
