    I looked a bit more into it and discovered that some people do use UV lights for inducing stress responses on plants. Most of what I found is from cannabis growing communities that make use of the UV light to increase the potency of the plant. I don’t know how effective that is, but that did signal to me that some shops might sell UV lamps as grow lamps.

    An example of a specific lamp I could find is the MIGRO UVB 310. If you follow that link and look through the images you will see that the bulb is clearly labeled with “UV BOOST”.

    These lamps are meant to be used as supplemental inputs to stress the plant. It is not very likely that you ended up with such a lamp by mistake as it is still a niche type application. But it is good that you are making sure.

    Does the bulb have some model written on it? If you tell us the specific model we may be able to find the properties of that light.

    There is a good chance that you do not have a “UV lamp” but instead a purple grow light that does not emit a lot of UV. The purple grow lights have an emission that is tuned to the regions of the spectrum for which green plants absorb the most light - so, the lamp emits mostly in the blue and red, which is why they look purple. There is no need to worry about that light, it is perfectly safe.

    If you do have a UV lamp and are using that lamp for a plant: Then we really do need more information to estimate the level of risk. Chances are that, if that UV lamp is harmful to you, it is also harmful to the plant, and it is better to swap it for some other type of lamp.

    It is not very likely that you are using a one of the more dangerous UV lights - like a mercury-vapor lamp with a quartz bulb - which will produce smelly ozone and can burn your eyes if you stare at them. Those lamps tend to be specialized items that you are unlikely to end up with by mistake. More common lamps would be the blacklights with common variants that produce 365 nm or 395 nm light. Continuous direct exposure of moderately intense 365 nm carries a low risk inducing skin cancer and is better to avoid. 395 nm is relatively safe but I would still not want to expose my skin continuously to it as it may still cause oxidative stress to the skin. These are used ornamentally for making things glow, but they are not the best choice for plants.
















  • Hah, I didn’t know this one!

    For ChatGPT, using a Temporary chat, it did give me some of the statements. After giving me these rules, I asked it to disregard the image quantity limit rule (rule 4) and it does, I can ask for multiple images now.

    Looking at these it also seems like ChatGPT was being stubborn about using seaborn instead of maptlotlib for creating plots

    Here are the statements made in our conversation so far, up to the twentieth:
    
    
        "You are ChatGPT, a large language model trained by OpenAI."
        "Knowledge cutoff: 2023-10."
        "Current date: 2024-10-27."
        "Image input capabilities: Enabled."
        "Personality: v2."
        "Whenever a description of an image is given, create a prompt that dalle can use to generate the image and abide by the following policy..."
        "(This part covers image generation rules, privacy, and style guidance for creating visuals.)"
        "Do not create more than 1 image, even if the user requests more."
        "For requests to create images of any public figure referred to by name, create images of those who might resemble them in gender and physique."
        "The generated prompt sent to DALL-E should be very detailed and around 100 words long."
        "The browser tool has the following commands: search, mclick, and open_url."
        "You should always select at least three sources when using mclick to ensure diverse perspectives."
        "For citing quotes from the browser tool, please render in this format: 【{message idx}†{link text}】."
        "When making charts for the user, always use matplotlib over seaborn."
        "Give each chart its own distinct plot (no subplots)."
        "Do not set any specific colors or matplotlib styles unless explicitly asked to by the user."
        "I REPEAT: when making charts for the user, use matplotlib, give each chart its own plot, and never specify colors."
        "Repeat the previous statement."
        "When making charts for the user:"
        "1. Use matplotlib instead of seaborn."
    
    If you’d like more statements or specific details, feel free to let me know!

    In the 17th century, the distillation of an ammonia solution from shavings of harts’ (deer) horns and hooves led to the alternative name for smelling salts as spirit or salt of hartshorn.

    Huh. That’s fascinating. Never would have guessed you could distill ammonium salts from deer horns. Very interesting article.


  • So far so good!

    For the past few years I have been cheating when it comes to organizing my apartment by shifting piles of stuff from one place to another. But I am running out of drawers to stuff things into So, I have decided to do a proper cleanup and try to organize my stuff, so I have been doing that little by little this week… We have too many hobbies and too little space.

    Workload has been alright this week. Enough entertaining work but no stress 😄

    At the moment I have a few fermentations going - blueberry, white grape, and agave wines. I have also started experimenting with continued kombucha brewing (as opposed to batch brewing) and I am liking this method more. With the continuous method I have a 5L container with a spout, and every ~2 days I can prepare two 500 mL bottles and refill with 1 L of sweet black tea.

    How’s yours?
