Do you need help identifying a 🌶?
Is your plant suffering from an unknown issue? 🤧
Then ask in Identification and Diagnosis.
lighting L.E.D lights??

I'm not gonna buy a "bulb", but I'll be making my own surface from LEDs.
Of course lumen output matters.
Here, read some more about lumens:

Take a good look at "Candlepower".

Why are they using blue and red LEDs only?
Isn't the fact you can use ALL viable lights, what's so great about LEDs?
You need some more yellow, green and orange lights.
In fact, orange light contribute more to chlorophyll activity than red.
You need to play with all kind of colors and their shades.

I did some research a while back when I was looking at the red mulches that are supposed to ripen your tomatoes faster. I stumbled across an article that discussed the effects of different colors on crop growth. I'll see if I can find it again, but I do remember that different wavelengths of light do stimulate different types of growth on some crops. Even within the red spectrum there were differences, and I remember struggling to find which company carried which type of red plastic mulch, because some would work, and some wouldn't.
Nice and vague, huh? I will try and find that article when I have a few minutes.
LOL agree with willard .....all on ebay is magic acording to the seller !? ebay is a good place to buy but you should know what you want .....to me leds are just to expensive for a poor lumen output ...the for indoor grow light is HCFL light like ( Envirolite,Smartlite..ect..)with 100%PAR and if you want big result use HPS or MH light with cooltube a lil more complicat but a lot more lumen
Now, here's an interesting article, although it's not the one I read before. It shows rates of early blight by mulch color. I'd not read anything about that before.

now IGG would like to mix LSD and peppers I betcha
There was a good discussion on here a few months ago. I did quite a bit of research on lighting and the biggest factor seemed to be PAR (Photosynthetic Activity Radiation). Not lumens, not watts, but how much of a light sprectrum is used by the plants.
The mulches (or plastics) are supposed to play a factor but realistically have very little effect once the plant gets very big, unless it is isolated. I used the red plastic this summer but because I didn't have acres of room to spare, after a few weeks, it was shaded by foliage, so very little light was reflected/absorbed. (A side note - white plastic is supposed to be great for potatoes, as it directs light that encourage root growth, or something like that!).
If you can do a Google search for NASA, plant growth, PAR and similar terms, you should be able to come across a very in-depth article about the merits of different lights, though NASA considered energy usage as a high priority. The study related to colonizing Mars, where growing food would be key to survival, since it would cost too much to ship them a care package every month.

I found some usefull info regarding led's at www.greenpinelane.com
Bwahahaha, see, this just goes to show I need to read all threads more often because sometimes I miss this stuff. Freakin' hilarious (I showed my mom and she laughed her ass off).LUCKYDOG said:You have to eat some then it is multicolored and has tracers and you see this guy gardening for you
Actually, LSD is sort of a razor's edge thing. I probably wouldn't recomend doing larger doses of LSD and then something that will induce pain (peppers). Now in small doses, I would probably say go for it. Since I'm currently only going to be doing incresingly larger doses, someone else may have to pick up the slack on that one and reposrt back.AlabamaJack said:
While I'm posting in this thread it reminds me of something my friend Dave Reed said. He always wondered if placing the plants in a closed or extremely dark place and exposing the plants to intense bursts of light (once every few seconds, LED or light bulb) would cause the plants to grow faster or stonger.
