Silic Rock. By Plagron.
If you've ever wondered why your neighbour’s plants stand up straight and proud while yours flop about like a wet noodle, the answer may lie in a single overlooked element: silicon. Specifically, Plagron Silic Rock - the newest addition to Plagron’s elite nutrient arsenal, and a game-changer for indoor growers. This isn’t just another bottle of fancy-labelled snake oil. This is a scientifically-formulated, Dutch-engineered silicon supplement with real muscle - and it’s here to turn your plants from soft-bodied sprinters into heavyweight champions of the grow room.
The Heavyweight Champion of The Grow Room.
At the heart of Plagron Silic Rock lies a highly bioavailable source of silicon dioxide (SiO₂), clocking in at a solid 1.0%. This means the silicon isn’t just present - it’s accessible. Your plants can actually take it up and use it immediately. And when they do, the results are unmistakable. Silicon fortifies individual cell walls, like installing steel girders inside each plant. Stems thicken. Branches firm up. The entire plant begins to carry itself differently - stronger, more upright, more capable of supporting dense floral growth without collapsing under its own ambition. You can almost hear it saying, “Bring it on.”
Smell What Silic Rock Is Cooking.
But Plagron Silic Rock doesn’t stop at brute strength. One of the lesser-known effects of silicon is its ability to make plants more efficient at retaining water. That’s right - by tightening up cell walls and boosting hydration efficiency, Silic Rock reduces water loss through transpiration. This becomes especially useful in indoor environments where lighting and airflow can quickly dry out growing media. With this in play, your plant spends less time gasping and more time growing - faster, fuller, and with far fewer signs of stress.
Vigorous, Uniform Growth. Fast.
Speaking of stress, it’s not just about heat and light. Pests, pathogens, and environmental inconsistencies all pose a threat to your plant’s performance. But when those cell walls are reinforced with silicon, they become much harder to penetrate. It’s like trying to cut through Kevlar with a butter knife. As a result, Plagron Silic Rock-treated plants show better resistance to bugs and microbial invaders. Less time fighting infections, more time producing vigorous, uniform growth - which is exactly what indoor growers are chasing.
Better Nutrient Transport.
Another key reason to keep Plagron Silic Rock in your nutrient rotation is its direct impact on nutrient uptake. Thicker stems and stronger vascular tissues mean better nutrient transport - particularly essential minerals like calcium, magnesium, and potassium. Silic Rock essentially acts as a physical and biochemical enhancer, ensuring your plants don’t just absorb nutrients - they utilise them efficiently. And since it’s a pure mineral product with an NPK of 1.5-0-1.7, it integrates cleanly into your feeding schedule without unbalancing your base nutrients.
For Growers Who Demand The Best.
Now, a quick but important disclaimer: Plagron Silic Rock is not suitable for hydroponic systems. This is a product designed for soil and coco-based setups, where it can fully express its benefits without gumming up the works. But if you’re in that category - from a modest cupboard grow to a full-on fruiting facility - this product is indispensable. Available in 250ml, 500ml, and 1-litre sizes, it’s compact, potent, and cost-effective.
So if you're serious about indoor growing and you want your plants to stand up to the rigours of life under artificial lights, Plagron Silic Rock is your secret weapon. It’s not flashy. It doesn’t smell nice. But it works - relentlessly, consistently, and on a cellular level. Because in the end, strong plants don’t just happen. They’re built - one fortified cell at a time.
