    I think people often try to overcomplicate relatively simple tasks such as this, and then they have to get a gadget for it. They use it once to get the data they were looking for, and after that they have a gadget they're never going to use again and probably will keep in a shed or basement to be stored forever, or throw it out. All of that wasn't even necessary because there were methods you could use without having to buy a specific niche tool, so in the end nature just has another gadget that it's stuck with.
    For me, the romance of gardening comes from the fact that you're trying to reconnect with nature, so niche gadgets such as this that are not truly necessary go against that way of thinking.

    I think to get a more accurate idea of the sunshine, you have to use a PAR meter and calculate the DLI.

      Agreed. Of course the problem is that commercially available quantum sensors cost around $500, and cheap lux meters measure visible light, and not Photosythetically Active Radiation, so neither of these are really appropriate for the general audience of this channel. An affordable solution from the indoor horticulture world is to use a ~$25 UNI-T UT383BT Lux meter along with the PPFD Meter app to generate PPFD and DLI calculations for PAR maps. The comparisons I have seen all benchmark against Apogee quantum sensors and the deviation is less than 4%, which is good enough for dialing in tent grows, and honestly overkill for outdoor gardeners who just want to know how sunny or shady a spot is, but it gets the job done, and is very simple to use.

      @@Noraf83 PAR meters can be found for 150 euros. I have one from the Photobio brand that works very well, but it is true that it comes at a cost. Your $25 system sounds interesting. Otherwise, you can always use your smartphone's camera and a lux meter to PAR meter conversion app, but it's not very accurate. Ultimately, apart from calculating the DLI indoors with a horticultural lamp as lighting, we can only have an approximation, whether outdoors or in a greenhouse.

      And who sells plants with that kind of accuracy on the label?

      @@Gardenfundamentals1 You are right, when you buy a plant or a tree, it is not indicated on the label this kind of information (DLI). But it is easy to find it on the internet, even by asking chatbots.
      When growing indoors professionally, the DLI is important information to maximize your production and the costs of electrical expenses.

    what about season consideration? isn't the sun angled differently throughout the year? sunny spots in summer are not that sunny in winter? I'm not sure about that if you can clarify

      @Gardenfundamentals1  Před rokem +1

      That does affect plants and where the shadow is. But remember, plant info is very limited - sun, part shade and shade. We don't need a lot of accuracy to pick one of those options.

    A lot of people have securty cameras. You can set them to take a photo at intervals. I set mine to take a photo every 15 minutes, and i had my area mapped out in no time.
    It’s pretty irritating to see peple waste money on gadgets that they don’t need.
