Greetings. I'm in need of some advice.
My seedlings are growing long and thin. Usually, there's enough light at their location, but the weather doesn't play along and it has been fairly dark for a while now.
In a kind of panic I ordered one of those LED plant lights (mostly red/blue, some white) from Amazon. It arrived today and I switched it on to see how it works.
I have some old analog luxmeter lying around, and I have no idea how accurate it is, so I used it for strictly comparing.
Up close, like 30cm with the LED unit I get the same reading that I get on a north window on a cloudy day (plants are currently struggling a bit on a south window with a reading approx. 3 times as high).
Am I missing something here? How useful are readings like that when it comes to plants and the supposedly specialized LED light? Do these lamps actually work to grow seedlings? I know some people here have some experience with them, judging from the pictures.
The light I have is rated 50W with an actual power consumption of 26W, according to the product information. The product page is in German, so idk if linking it helps.
