Unit price perBotanixx Silicon 1L – Built-In Strength, Right Where Your Plants Need It
Strong plants start with strong structure – and that’s where Botanixx Silicon comes in. Whether you’re growing in polytunnels, under LEDs, or out in the open, this additive gives your plants the backbone they need to stand strong and thrive.
It’s not hype – silicon helps plants build firmer structure, absorb nutrients more efficiently, and cope better with heat, light, pests, and stress. You’ll see it in the way they hold themselves: upright, steady, feeding well, and finishing strong.
It’s not about shortcuts. It’s about giving plants what they need to get on with the job. When the structure’s solid – strong stems, firm leaves, reliable roots – they stay upright, feed properly, and keep pushing on even when conditions aren’t ideal.
Why growers use Botanixx Silicon:
- Builds natural strength from the inside out
- Improves structure for upright, self-supporting growth
- Boosts nutrient uptake through healthier roots and tougher tissues
- Enhances resilience against heat, drought, and light stress
- Thickens leaves for more efficient light conversion
- Reduces pest and disease pressure by toughening plant surfaces
- Limits heavy metal uptake in sensitive crops
- Contributes to bigger, heavier yields without extra input
No gimmicks – just real, built-in support for serious growers who want structure, balance, and strength where it matters.

Botanixx - pH Up – Reliable pH Control for Professional Growing
Low pH can quietly undermine a crop. Once it drops below 5.5, nutrient availability – particularly calcium, magnesium, and phosphorus – takes a hit. Plants start to show it: twisted leaves, weak roots, stalled growth, even when feed levels look right on paper.
Botanixx pH Up offers a clean, effective way to correct this. It raises pH steadily, without foaming, clouding, or affecting your system. No build-up, no waste – just a dependable correction that slots easily into any setup, from hydro and coco to flood and drain.
Why growers and resellers trust it:
- Supports calcium and magnesium uptake for stronger, more resilient plants
- Releases phosphorus for improved rooting and flowering performance
- Precise control with no chemical residue
- Compatible with all common commercial growing systems
- Highly stable formulation – clean, concentrated, and consistent
Ideal for use when:
- pH levels drop below 5.5 and uptake is compromised
- Visible signs of calcium or magnesium deficiency, despite feeding
- Runoff or reservoir readings consistently fall outside target range
Supplied in 500ml, 1L, 5L and 10L formats.
Reliable, trade-grade pH management for serious growers.

Botanixx - pH Down 30% – Keep Your pH Where It Should Be
If your mix starts creeping above 6.5, you’ve got a problem – micronutrients like iron, zinc and manganese stop being available to the plant. They’re in the tank, but locked out. That’s when the yellowing starts, growth slows, and yields begin to dip.
Botanixx pH Down gives you a clean, accurate fix. It lowers pH quickly, without any clouding, foaming or residue – just a stable adjustment that gets your nutrient solution back into the uptake zone.
It gets to work fast, drops the pH cleanly, and won’t leave behind any gunk, foam or haziness – just a tidy correction that keeps your feed where it should be.
So, why do growers stick with it?
- Brings down pH fast and accurately
- Keeps trace nutrients available for efficient uptake
- Won’t clog filters or leave residue in tanks
- Safe to use in hydro, coco, soil or foliar feeds
- High strength – minimal volume needed per dose
When to use it:
- pH reads over 6.5 – adjust before applying
- You’re seeing early signs of nutrient lockout
- You need tight pH control for coco runoff (aim 5.8–6.2)
Available in 500ml, 1L, 5L and 10L sizes.
Trade-friendly, consistent, and ready for commercial use.
