hey is that a mirror on the bottom???????
If so get rid of it they soak up more light than they reflect, again I know this is very much true.

Thanks, That was in there for the photo effect, this isn't my first grow, I used to hang out alot over at IC Mag. This is just my first LED grow. I came here cause the layout was better and seemed like a new place would be cool to kick something like this off.....I like the feedback.....Lots of ppl hate them say there shit, now mine may look like they were made in china and sold at a 75% margin. There not, my father in-law built them for me, I pulled the specs off the one on ebay (like design). Sent them to him and he got me 900 LED's that are .675watts, he has a degree in electronic engineering so its not like they were produced in a factory downtown, anyways feel free to follow along and see how they will turn out.

well some are to spec but it's pretty iffy.
I hope it works tho, it seriously won't take you into flowering tho, they simply don't put out enuf.
What color are they???

Ill keep watching tho, always open to new ideas!

Blue and red. well see what happens over time, I might have to admit defeat on the the LED therrrry

No I mean what color spectrum, not blue or red

like in kelvin?
If you don't know then that's not a good thing.

There messured in Nanometers

Cool concept, and sweet panels!

I would think though that they don't produce enough lumens or have nearly the necessary light penetration for flowering. But I'm not sure how LED intensity is measured.

And that's what experiments are for right?

Subscribed. +Rep for sweet handmade LED panels and a curious mind.

nanometers is size not color spectrum.
Here I found this in a thread, if your light's do not produce the correct color spectrum your plants won't like it at all.
Sure they can sprout, I use 6 2' T8 32W 4200K floros for seedlings but they would suck to use on a plant.

I do like your creativity though, not knocking that at all. Like I said I am a new grower but I have done my research, you prob should get some CFL's/floros within a week.
Well it's about time to toke up again just pit my babies to sleep. another 2 hours to shut down the veggies

Color Temperature
In scientific terms, Kelvin temperature is a measure of the color of a light source relative to a black body at a particular temperature expressed in degrees Kelvin (°K).

In simpler terms, it is the degree of warmth or coolness of a light source, not with regards to the physical temperature, rather to the visual temperature of the light. The higher the degree K, the bluer, or "cooler" the lamp appears. The lower the degree K, the more "warm", or red the light appears.
Incandescent lights have a low color temperature (approximately 2700°K) and have a red-yellowish tone; natural daylight has a high color temperature (approximately 6000°K) and appears bluish. Today, the phosphors used in fluorescent and high intensity (HID) lights can be blended to provide any desired color temperature in the range from 2800°K to 6000°K.
LED lighting can also be blended to provide any desired color temperature except LED lighting is measured in nanometers.


Color Rendering Index (CRI)
The Color Rendering Index (CRI) is a rating scale for light sources (lamps) from 0 to 100 to indicate how accurately colors can be perceived under a light source. The higher the CRI, the more accurately colors appear. Technically, CRI ratings should only be compared for lamps with similar color temperatures (Kelvin ratings)
A specific example may make this a little clearer. Tungsten light -- 3200K -- is a full spectrum light, that is, it is emitting light over the entire visible spectrum. Red, orange, yellow, etc. Sunlight is also a full spectrum light, but at a much higher Kelvin rating, but still contains red, orange, yellow, etc. Many other light are also full spectrum xenon, carbon arc, but have different proportions of the various wavelengths.

Each of these full spectrum light sources contains light at a near infinite number of different wavelengths, at which can be measured in nanometers. Visible light being the region between 400 and 750 nanometers.

A very specific color would have a very specific wavelength. For example, a ruby laser has a wavelength of 694nm.
By combining different LED wavelengths a full spectrum can be achieved.



Hope this helps

Thanks man, Hope you enjoy your time here. lol
