Effective Rooting Hormone – Long-Lasting, Easy to Mix, Proven Results
Customer Review – Naphthaleneacetic Acid (NAA): Reliable product. I’ve used it consistently for about a year with great results. The bottle it comes in looks different from the listing photo, but the quality is solid. How to Mix: To prepare, dissolve the amount you need in a small amount of pure ethanol or high-proof alcohol (2–5 mL). Stir or shake until fully dissolved. Then slowly pour that into 1 liter of water, mixing well. This avoids clumping and makes sure it blends evenly. Use the mix right away for best results. How to Use: • Root Drench: Pour around the base of the plant to encourage strong root growth. Works well for cuttings and transplants. • Foliar Spray: Lightly mist leaves for propagation or tissue growth. For better absorption, add a small amount of non-ionic surfactant (like a drop of baby shampoo or specialized plant wetting agent). Don’t spray during hot, sunny hours—early morning or evening is best. Storage Tips: • Store the powder in a cool, dry place, ideally in the fridge (2–8 °C). Lasts up to 3 years if kept dry and out of light. • At room temperature (around 25 °C), it’s fine for a little over a year, as long as it’s in container closed well and kept dry. Adding a silica gel desiccant and oxygen absorber to the container is a good idea. • Once mixed in water, use it right away—it breaks down fast in liquid form. Highly effective for rooting and plant growth. No issues with stability or performance when stored and used correctly.
