I want to make LED plant grower. . .How do I do it?
I heard that I could use bright white LEDs from flash lights and hook them up in series to be able to grow plants indoors or using my computer’s usb, but I just don’t see how thats possible. I also seen how I could take a lot of red LEDs and a few blues ones and it would do the same, but I don’t see how normal red and blue LEDs could do that. It seems I’m over thinking this, but wouldn’t I need a special type of LED to do anything? I’m new to this and any help would be awesome.
I’m using the LEDs to grow tomatoes all year round, encase anyone was wondering. I’m not stupid enough to grow “other” things.
I’m not sure about white LEDs being used, but you’re right in thinking that a combination of red and blue LEDs is ideal. What you need from lights to help plants grow is not the heat (which is why LEDs work well, as they won’t burn the leaves like other kinds of light), but light at a certain frequency.
Photosynthesis in plants is most effective with light at 410-440 nanometers (in other words, blue), and 660-680 NM (red). (You want to avoid yellow and green lights, but purple is 430-440 NM, so that would work too). So you can use red and blue LED strip lights or light bars, and alternate the sections, and all of the lights can be powered by a 12V plug-in adapter, or hard-wired with a 12V transformer. Strips and bars also come in waterproof versions, so they work in a greenhouse.
