I am working on a project to use recycled self watering 2lt and 5lt plastic bottles to grow vegetables. I have read that a high frequency 20-60 kHz may act as a pest deterrent. The containers are filled with 15% water and the above compartment is filled with soil. I just wanted to know if it is possible to get a high frequency sound by using a straw or similar that extended from above the soil to the water below? .
Thank you.

Re: High frequency as pest deterrent
Using a straw or similar device to create high-frequency sound in your self-watering vegetable containers may not be practical or effective for pest deterrence. Let's break down the reasons:
1. Frequency Range: The frequency range you mentioned, 20-60 kHz, is indeed known to act as a pest deterrent for certain pests like rodents and insects. However, generating high-frequency sounds in this range typically requires specialized electronic devices or ultrasonic transducers. Using a simple straw won't generate the necessary vibrations to produce such high-frequency sounds.
2. Transmission of Sound: Even if you were to somehow create high-frequency vibrations using the straw, it's doubtful that the sound would effectively transmit through the water to the soil and the plant roots. Water tends to dampen sound waves, especially high-frequency ones, making it difficult for the sound to propagate effectively.
3. Pest Deterrence Effectiveness: While ultrasonic pest deterrents can be effective for some pests, their effectiveness can vary, and they might not be sufficient on their own to keep all pests away. Pests can adapt to certain stimuli, and using a single method might not be as effective as employing a combination of various pest control strategies.
4. Alternative Pest Control Methods: Instead of relying solely on high-frequency sound, consider incorporating other proven pest control methods in your vegetable containers. Some effective natural pest control methods include introducing beneficial insects, using physical barriers like netting or traps, practicing crop rotation, and selecting pest-resistant plant varieties.
5. Recycled Bottles for Self-Watering: The use of recycled bottles for self-watering is a great idea for your vegetable project. It helps conserve water and provides a consistent water supply to your plants. Focus on optimizing this self-watering system to ensure your plants get the right amount of water while avoiding overwatering, which can also attract pests.
In conclusion, using a simple straw or similar device to create high-frequency sound for pest deterrence might not be feasible or effective. Instead, explore other proven pest control methods and focus on perfecting your self-watering system using the recycled bottles to grow healthy and pest-resistant vegetables.
