Storage and handling Hortus IBA Water Soluble Salts dry powers and solutions
STORAGE AND KEEPING LIFE
Dry Powder Storage:
• Dry powders have unlimited life: Always keep the dry powder in its original container with the cover tightly closed.
• Moisture Control: If the powder is exposed to ambient moisture, lumps may form. This does not cause a loss of active ingredient efficacy. Lumpy powder can simply be dissolved in warmer water (up to 180°F) prior to use.
Solution Keeping Life & Storage:
The functional lifespan of the mixed aqueous K-IBA solution depends on both its baseline chemical stability and the application method used:
• Stock Solutions: Once dissolved in ordinary water, the K-IBA in the rooting solution degrades at a rate of approximately 5% per month at ambient room temperature. This degradation slows slightly when stored in cooler environments (e.g., the 40's °F). Avoid prolonged exposure to direct, bright sunlight; however, short-term bright light and continuous nominal room lighting are normal and perfectly acceptable.
• Spray Drip Down (Multi-Day Use): Because the solution is sprayed once and never recirculated, there is no risk of cross-contamination from plant material . Unused solution remaining in the sprayer tank can be retained and safely used for subsequent production lots over several days.
• Total Immerse and Quick Dip (Single-Day Use): Dipping plant material directly into the solution introduces organic matter and potential pathogens. For clean, homogeneous lots, the mixed solution can typically be kept and used for the duration of that production day. However, to prevent cross-contamination, the best practice is to dispose of the solution at the end of the workday, or immediately when switching between different plant varieties.
Solution Disposal
• Spray Drip Down: The solution is sprayed once and never recirculated, there is no risk of cross-contamination between production lots. Unused solution remaining in the tank can be retained and used for subsequent lots over several days.
• Total Immerse and Quick Dip: Dipping plant material directly into the solution introduces organic matter and potential pathogens. For homogeneous lots, where a single, clean plant is being treated, the solution can typically be used for the duration of the production day. When treating varied lots or switching between different plant varieties, the best practice is to discard the solution, and make a fresh solution to prevent cross-contamination.
