Product description
Emerald Harvest Sturdy Stalk 22.71 L: product details and use
Emerald Harvest Sturdy Stalk is a potassium silicate supplement (NPK 0-0-1, 11.2% silica). Silica strengthens the cell walls, so your plants build stronger stems and branches that can carry heavy flowers and fruits and better withstand stress.
Use it from early veg to late flower; it really pays off when flowers and fruits start gaining weight. The 22.71 L drum (6 US gal) is made for large grow rooms and big irrigation systems.
