STS Spray vs Colloidal Silver: Which Is Better?Updated 12 days ago

Between the two options, STS (Silver Thiosulfate) spray is generally the preferred choice for plant reversal.

STS is widely used by experienced growers because it’s more consistent and effective at encouraging pollen production, often with fewer applications and more predictable results.

Colloidal silver can also be used, but it typically requires frequent applications over a longer period and tends to produce less reliable outcomes. Because of that, it’s usually considered a secondary option.

Our Take 🌱

For growers looking for dependable results, STS spray is the better tool. Colloidal silver may work in some cases, but STS is more efficient and widely trusted in breeding-focused grows.

⚠️ Important: Plants treated with STS or colloidal silver are not intended for consumption.
