Strong plants start with a strong structure, and that is exactly where Botanixx Liquid Silicon comes in. Think of this as the essential "armour" for your collection, giving your plants the backbone they need to stand strong and thrive, whether they are growing under powerful LEDs or out in the open.
Available in both 500ml and 1L bottles off the shelf (or in 5L or 10L on special order), this additive is not just hype, it helps your plants build a firmer structure from the inside out. You will see the difference in the way they hold themselves.
Builds Natural Strength: Silicon integrates into the cell walls, helping plants build a robust structure that supports self-supporting, upright growth.
Pest Defence: By toughening plant surfaces and tissues, this supplement reduces pest and disease pressure, making your leaves harder for bugs to penetrate.
Stress Resilience: It enhances resilience against heat, drought, and light stress, helping your jungle cope when conditions aren't ideal.
Nutrient Boost: It boosts nutrient uptake through healthier roots and tougher tissues, ensuring your plants feed properly.
If you collect high-value variegated plants (like Monstera Albo or variegated Alocasias), Silicon is a non-negotiable addition to your routine. Variegated sections of leaves lack chlorophyll and are structurally weaker, often leading to browning or "melting." Botanixx Silicon thickens leaves and strengthens those delicate cell walls, keeping your variegation crisp and preventing those dreaded brown edges.

Pro-Tip: Mixing Order Matters
