Buying Guide: Key Purchase Considerations
- Plant type and cuttings: Delicate vs. woody cuttings require different IBA strengths. Softwood, semi-hardwood, and hardwood cuttings often benefit from tiered strength options (0.1%, 0.3%, 0.8%, 1.6%).
- Active ingredient: Indole-3-butyric acid (IBA) is the most common rooting hormone and is effective across many species. Ensure the product notes indicate suitable use for your plants.
- Medium compatibility: Most rooting powders work across soil, soilless mixes, rockwool, coco coir, and hydroponics. If you use hydroponics, verify compatibility with your system.
- Formulation type: Powder vs. concentrate vs. gel. Powders are simple and fast-acting for dipping cut ends, while concentrates or gels may offer alternate application methods or longer shelf life.
- Reusability and dosage: Some packets are large or intended for repeated use; consider your propagation scale and whether you need multiple units or a single large package.
- Safety and storage: Keep away from children and pets. Store away from heat and direct sunlight to maintain potency.
- Brand trust and compatibility: Reputable brands like Hormex, Garden Safe, and Bonide provide consistent formulations and clear usage guidelines, which can help with predictable results.
