Emerald Harvest Sturdy Stalk 0.95L

Silicon is one of the more underutilised elements in hydroponic nutrition despite having well-documented structural and protective benefits. When the plant takes it up, silicon is deposited in cell walls as a rigid silica matrix, physically thickening and strengthening the cell structure throughout the plant. This translates to sturdier stems that can support heavier flower and fruit loads without staking, improved resistance to physical damage, and a more robust barrier against pest ingress and pathogen penetration.

Sturdy Stalk provides soluble silicon from potassium silicate at a high 11.2% silica content, one of the most concentrated liquid supplement formulations available. The potassium component contributes additional bloom-boosting support, making Sturdy Stalk a useful complement to the primary bloom program rather than a purely structural addition. Stronger cell walls also allow the plant to redirect energy that would otherwise go toward stress responses into productive growth, flowering, and yield. NPK: 0-0-1. Shelf life 10 years or more.
