The active ingredients in Sturdy Stalk, silica and potassium, are provided in the form of potassium silicate.
Silica bulks up plant cell walls, so that plants can support as much fruiting and flowering as growers’ skills and their favorite plant strains allow without damaging or running the risk of losing the crop.
Silicon is one of the most abundant elements in the universe. In outdoor gardens, if the soil is rich in minerals, plants get silicon naturally, while hydroponic gardens may require a supplement.
The challenge for indoor gardens is not applying silica, necessarily, but rather, applying the right form of the nutrient silicon.
