Bulletproof Si ® delivers silicon in a form that may be utilized in virtually any fertilizer regimen. The silicon form, (Si), has been shown to strengthen plants, promote resistance to stressors, and promote an advantageous upright stature which leads to favorable exposure of leaves to light.

Bulletproof Si ® is formulated without a potassium source to facilitate application flexibility. Bulletproof Si ® is extremely beneficial in hydroponics, soil, and soilless growing media. **NOTE** A strong aroma similar to ammonia is normal in Bulletproof Si. The proprietary enzymes used in the formula produce a sour, almost acetic smell. Always shake very well before use.

In addition, Bulletproof Si ® is designed for use in continuous feed, drain to waste, and traditional soil growing applications.

Bulletproof Si ® is recommended for use with all Cutting Edge Solutions® products, as well as other commercial hydroponic nutrients. Bulletproof Si ® can be applied as a traditional root feed in all stages of plant life, or as a foliar feed in the vegetative phase.

Use lighter solutions of Bulletproof Si ® for young plants and perennials. Higher strength solutions are best suited for fast growing annuals, during both vegetative growth and fruiting/flowering.
