Stay Safe
- 🛡️ Wear goggles, gloves, long sleeves—respirator if working indoors
- 🧪 Add SH to water, never the reverse. Prevents dangerous splashing.
- 💨 Ventilate well—SH fumes are strong
- 🌿 Rinse or cover plants before and after—SH kills vegetation
- ⏱️ Let it dwell 10-30 minutes before rinsing. Don't rush it.
- 🧽 Flush the injector with clean water right after
