Buying Guide
- Propagation method: Powder works well for dipping cut ends; liquids are effective for water propagation and broad substrate compatibility; gels offer neat, minimized mess for indoor use.
- Plant type and cuttings: Woody or semi-hardwood cuttings may benefit from higher-strength powders (like Hormex #8); herbaceous and delicate cuttings may respond better to milder formulations and gels.
- Ease of use: Beginners often prefer dip-and-plant powders; experienced propagators may opt for concentrated liquids or gels for precise control.
- Storage and shelf life: Store unopened products in a cool, dry place. Liquid formulas typically have longer shelf life when tightly capped; powders may clump if exposed to moisture.
- Safety and handling: Use protective gear as needed during handling, especially with powders; avoid inhalation and contact with skin or eyes.
