Led Users Unite!

First I had heard of the Emerson enhancement effect... ty for that. That helps to validate the use of a far red LED according to photosynthesis and not just "promotes flowering" like some patents suggest. Good read on google. Also, does anyone play music for your plants to help them grow? Apparently they like Indian music, but I'm going to play bird songs for mine-- maybe they'll recognize the tune and start dancing.

oh look another person that got scammed by people selling the emerson efect bullshit hope you don't get turned into the cops by the one that makes those lights like they did to someone on icmag

I bought my lights before I knew about the emerson effect which is a legitimate study about the effect of multiple wavelengths. adding 740nm increases trichome production whether it's by increased photosynthesis or by stressing the plants with near IR I'm not sure. I'm not sure of the whole cops icmag thing your talking about? My question was whether or not adding UVB (310nm) would help if you already have 740nm. I've seen plants grown with and without 740nm and the trichome production difference is obvious. I added UVB during the first month of flowering and you can see the results below but I'm curious as to whether or not adding just one wavelength or both are more benificial

I'm not sure of playing music for them but there was a study done where a man entered a garden appearing to be normal. then he ripped a plant out of the garden and stomped it to smithereens. scientists had put sensors on the plants and when he stomped on the plant the other plants freaked out. after they had calmed down the man entered the room again and the plants freaked out again. maybe music will calm your plants and help them grow. you might try stomping on one of your plants to stress the others into more trichome production

Bubbleponics.com. irishboy is over there. Lots of legit LED journals

Well, whatever the reason is, Metal Halides have long been heralded as making higher quality of bud but making is less dense and airy. HPS makes bud more dense and makes for lower quality bud in comparison.

I have seen this theory being justified by the wavelengths being shorter from MH's, indicating, or at least hinting towards, UVB.

Whether or not thats bullshit? I don't know.

The sun gives off UVB and IR, so I cant see it hurting. But the sun also gives off green light, which is poo poo for plants. So whatever.

"adding 740nm increases trichome production whether it's by increased photosynthesis or by stressing the plants with near IR I'm not sure"

youre talking about uvb for trichome production emerson effect only workson photosynthesis first pr triggered by 660-670 then the chlorophyll will prefer 720-740 for pfr reaction then go back to pr and want 660-670 again

"Also, does anyone play music for your plants to help them grow?"

some dudehas a patent using sound to help plants grow

The studies I've seen indicated that plants did best with classical music. Generic noise had little effect and music with heavy bass like hip hop or dance music the plants enjoyed the least. Not sure what that means for the vibrations theory since classical would have very little bass/vibration and it was the best. I've heard that its good for infants to listen to classical music too. Whatever it is, classical just seems to have a good effect on things. I always listen to Mozart radio on Pandora when I'm doing school work, hopefully someday it makes me crazy smart!

too quiet... where'd all the shills go?

What is the grow period for LED's..Does it take a lot longer. I haven't really heard many folk's talking about it. Really, any light is a good light for a plant, some are just more powerful than some. So descriminating against a certain light is just plain ignorance, especially if you've never tried them yourself, so all the hater's can pipe down! lol, for real

I think if there is really much difference in how long they take that it would maybe be that they fill out sooner but take a little longer to finish? It probably only takes longer if you have a crappy LED light (or one that while top of the line for its time, is quite out of date)

No shills, just legit LED growers

Led action.

classical is loaded with bass bro what are you saying classical has little bass you want bass hit up most any classical piano piece

On what planet man? Like I said earlier, I listen to Mozart radio regularly. My computer system has a sub under the desk that I rest my feet on and there is zero rumble in most of it. There are some symphonies with some darker bass lines but loaded with bass is completely inaccurate. My point was the vibrations from bass probably AREN'T what the plant liked as classical has little bass and the types of music the plants responded the worst too has LOTS of bass. Aren't you the same guy that pretended insulating a room would allow an HID to heat it during 12 hours of darkness? You're pretty spot on with some of your LED technical stuff (at least it seems like you are) but these simple concepts I cannot figure out where your conclusions are coming from! One, or both of us is/are too high!

"Aren't you the same guy that pretended insulating a room would allow an HID to heat it during 12 hours of darkness?"

i see you got a reading comprehension problem bro read back some and see what the other people that can infer said and maybe while youre at it learn how cocrete and insulation can keep a room nice and hot long after a light goesof how you think your house stays col or hot insulation keps shit in and out and concrete slabs wil heat up absorb energy and radiate it out

ballpark...how hot do the leds get? nowhere near as hot as a hid i imagine but hotter than a flourescent?

The max temp I have seen has been 100 degrees F on mine. (and thats exaggerating) It tends to hover in the 80-90 range. (at least mine)

If the concrete is against the ground it will tend to radiate the ambient soil temp more than the light temp, thats why foam insulation is crucial in concrete rooms. (like mine). Changing the temp of subgrade concrete takes a phenomenal amount of energy, and though I am sure that grow lights have an effect, it would take a LOT of HID's to push the temps of the concrete far enough and deep enough into the slab to have a radiant effect.

With that said, once concrete does heat up it exhibits a bootleg ceramic like radiance. Still, above grade and below grade are crucial parts to that argument.

btw hall of the mountian king, 1812 overture, canon in d, what do you mean no bass those got plenty of bass and theres tons more from symphony to old classical organ music oh also toccatta in b thats low as fuk there itll make your subs bottom out and die

I actually test very high in reading comprehension and I can't believe you're actually using the word hot to describe the temp after the lights go off. There is no way enough heat would get stored up in your insulation and concrete to heat and otherwise dark and cold room for 12 hours. I just confirmed that with a construction engineer friend who works for Wietz and is a fellow grower. He laughed when I told him the scenario. I believe his exact quote was "yea maybe if he had 10 or 15 1000 watts that were a few inches from the pavement for 12 hours." Sorry broseph...

As far as bass in classical, the majority is still LIGHT on the bass. I don't recall claiming classical had zero bass, but if I did that is incorrect. My point all along was that people think the vibrations from music is what makes the magic happen but non musical noise and music with heavy bass (again referencing rap and dance music) were less desirable to the plants. I feel like I'm saying the same thing over and over, who has the comprehension problem?

I just saw this after I finished my response to budlover. Interesting to see you and my engineer friend said basically the same thing. Good man hudson!

I'm really not trying to start WW3 guys, just again trying to stop the spread of misinformation. An HID will heat your room when it is on, it will not do anything during lights off because it is off. It may have some radiant heat for a few hours after from both the reflector and possibly the concrete, but not the entire 12 hours. If your environment is cold enough to need heat, you will need a heater.
