The Deficiency You'll Never Spot

Most plant deficiencies announce themselves with yellow leaves, brown spots or curled edges. Silicon deficiency doesn't. Plants short of silicon simply grow a little weaker, absorb nutrients a little less efficiently and cope with stress a little worse, and nobody ever notices.

Plagron Silic Rock fixes that hidden problem. It supplies silicon in a form plants can easily take up, in an optimal ratio with potassium. Silicon strengthens cell walls, improves resistance, and helps plants mobilise less mobile nutrients like phosphorus, calcium and micronutrients from the soil.

Why It Works

Stronger cell walls: sturdier stems and leaves that resist stress.
Better uptake: improves absorption of phosphorus, calcium and micronutrients.
Improved resistance: plants better able to cope with challenges.
Tiny dose: just 1ml per litre at every watering.

For Houseplant & Garden Growers

Leggy seedlings, floppy stems and plants that sulk at every change in temperature all benefit from silicon. Add a splash of Silic Rock to every watering for sturdier, more resilient houseplants and veg.

For Growers

Dose: shake well, then add a maximum of 1ml per litre of water (1:1000).
When: at every watering, through the entire grow.
Not for: NFT, DWC or aeroponics. Silic Rock is of organic origin, so use it in soil and coco.

Rose's Pro-Tip: Silicon products should go into your water first, before any base feeds or acids. Stir well, then add everything else.
