Buying Guide: Key Considerations For Liquid Rooting Hormones
When selecting a liquid rooting hormone for water propagation, consider the following:
- Active ingredients: Indole-3-butyric acid (IBA) is common and effective for rooting. Look for products that balance hormones with vitamins or natural extracts for improved root health.
- Medium compatibility: Ensure the product supports water propagation as well as soil and LECA if you switch media.
- Application method: Droppers offer precise, mess-free dosing; powders can be harder to apply evenly and may clog hydroponic systems.
- Transplant shock reduction: Choose formulas explicitly designed to reduce shock during potting or repotting to support continuity in growth.
- Shelf life and storage: Some formulas are shelf-stable for years; store away from heat and direct light for best results.
- Plant compatibility: Most products target common houseplants, but verify compatibility with pothos, monstera, philodendron, fiddler figs, and herbs if relevant.
For best results, follow product-specific guidelines: typically, add a full dropper per quart of water for initial propagation and continue as needed for the first 4–8 weeks, depending on the plant and medium. Always clean tools and avoid cross-contamination between mediums. Reading the included plant guide or data sheet can further improve success rates.
