"Far-red light is light at the extreme red end of the visible spectrum, between red and infra-red light. Usually regarded as the region between 700 and 800 nm wavelength, it is dimly visible to some eyes. It is reflected or transmitted by plants because of the absorbance spectrum of chlorophyll, and it is perceived by the plant photoreceptor phytochrome."

So it's not IR but just before it. IR LEDs would do no good, just produce heat. Maybe the red LEDs extend a little into the 700-800 range. In the LumiGrow spectrum graph it cuts off at 700 but you can see that it still hasn't completely flatlined yet at that point. I guess it must be enough far red to maintain normal growth.


Bob the above qoute makes far more sense, maybe the info being given by TI is smoke and glass and this is why!!! your statement "it is dimly visible to some eyes" this actually discribes the lights I'm seeing a faint red glow in the center of the bulbs with no visible light being projected. So maybe these 12 bulbs are the far-red bulbs you are describing and the information I'm getting isn't valid.

If you do a search in google images for uv led you see that they produce a violet color, not clear or reddish. Pretty much like a blacklight.

Well,

Based on your descriptions the 12 pro bloom leds are not UV, they would appear to be far red! shocked

Well,


Here are the shots 2 weeks after removing the root rot and just prior to cutting, trimming and drying.

What size area was the lamp covering 3x3?nice sized buds. I have ben thinking about buying into the led.Most buds were small and strechy on other grows.I have seen. kewlpics

Just a note about the TI smartlamp. I have spent alot of time looking at LED's as I thought about trying to build my own. I gave it up after pricing out the components.
anyway. I found a few close ups of the smartlamp online, all the led's they use are philips rebel or K2's. (150 of em, 105 red
18 blue,15 white,12 amber/green )

Guess what, Philips makes NO led's that are deep red, far red,IR or UV. check it out for yourself, either on philipslumileds.com or on future.ca . Now there IS a "dental blue" that gets near UV, but it has been discontinued. It also cost over 60 bucks from future electronics!
So maybe the smartlamp has miniscule amounts of IR and UV as a consequence of the spectrum of the blue and red LED's used. It certainly is going to be no greater than any other LEd light on the market.
their "pro-bloom" option is simply some mix of the availble LED's in the cyan to red orange part of the spectrum. I would love to be shown an actual graph of their output that proves me wrong.
None the less, if Frodo is using a smartlamp, it looks like it is working well enough.

Dave,

My area is 31" x 31", so just under a yard each way. Yes, nice size buds for rez temp being in the high 80's, lamp more then 2 feet from the canopy until the last half of flowering, and massive root rot. With all of these issues I shouldnt have had nice size buds but I did.

My next gow will be gangbusters!
Order a chiller for this grow!

JTF,

I have flipped over my lamp several times, and I have no idea how you can tell the manufacturer of these small leds even with a magnifying glass, but maybe you can.

I can state that I've never seen far red leds, but I have seen the normal spectra reds, blues, oranges, greens and whites. The 12 pro-bloom bulbs arent any of them. If you read my earlier post closesly I stated no visible light is being emitted from the LED, all you can see is a faint red glow in the center of all 12 leds. The red glow is the site of the led firing, but what ever light is being generated isnt in the normal visual range. You see no light coming from the led other then a faint red pin point glow in the center of the led.

So I totally disagree with your assessment of the 12 pro-bloom LEDS being run of the mill LEDS. I repeat I looked at a number of LED devices of all types in person, and I have never seen any LEDS that look remotely close to these.

i did a grow in a space similar to your size for awhile once. yes, i did rig-up a chiller, not the real deal, but a remedy. what i ended up doing was cutting a hole in the wall and setting the rez in the joining room. thats what i think you are going to do with your chiller- set it up outside your tent. if so, why not move your res out of the tent also. the chiller i rigged up was a water cooler and setting the plant right ontop. that kept the roots cooler in the warm room.

your light produces some beautiful blooms. i'm gonna love what it produces next.

JTF is right, but Frodo is also right. Philips does not make far red. Frodo says that there is no visible light coming from the LEDs, this would indicate IR. maybe the diodes arent the same as the ones that you are stating that they are, i dunno.
