Light Intensity; LED vs HID

[doz]

A friend just did the Apache at-600 vs the 1000 watt de nanolux and they came out close. The Apache bud was frostier though. He told me you need at least 3 ft of distance too or it will bleach the tops. Even my gavitas aren't that intense. But the Apache is running at like 600 watts. I just recently tried the cheapies and they did good for a small grow. I use the LEDs too to clone with and veg now too before they go to the metal halides but even those I'm debating switching at some point

There is no way that an AT-600 will be too much light @ 12" let alone 36"..... This is false and bullshit information that for some reason continues to be spread. I am running 600w of CXB3590 6-8" in a 4x4 area from my tops and have no light bleaching. You are telling me that AT-600 is more intense? At 36" no less? Company paid shills say this kind of bullshit nonsense.

They run the light at 36" cuz the light coverage SUCKS, no other reason.

I would have to agree with this, LEDs intensity isn't that high, even the best ones can almost come to touching closeness only reason to lift them higher is cause coverage is horrible. That guy's post screams false information not to mention he just joined the forum the day he posted that.

I disagree. I also think you are confusing heat intensity with light intensity. If you put my light "close to touching" you're going to burn the plant from the light intensity. If it's humid enough, you can burn your plants from 12" away. I have turned 3 3-week-veg'd plants completely brown and wilted in under a day because I underestimated the intensity of my LED and how close it was to them. I won't do that again.

I'm gonna have to say you are wrong and don't have enough air conditioning / air flow for your area or overfed salt nutrients. You can burn plants feet away if you over feed salt nutrients but that has nothing to do with a light bleaching a plant.

 

[Yodaweed]

Light bleaching makes your buds turn white and your leafs turn white from super fade, not burning them that's from over heating from lack of air flow and air conditioning.

 

[Yodaweed]

You guys never got hash tip on a bud from over exposure? Turns the tip of your buds white as fuck, that's from too much intensity its not a burn.

In the winter, at 68 degrees indoor temperature? Wrong. And I'm all organic, so no salts.

I think you confusing burning your plant from heat with too much intensity, burning = plant burns looks like it cooked , too much intensity = hash tip bud turns white on the tips or wherever the light was too much , literally bleaches the color out of the plant turns it white.

No, dude. You're way wrong. I switched them from CFL to a 500w LED and they were obliterated. You're trying too hard to be right rather than actually knowing what you're talking about right now. I haven't had one death since, either.

 

[Olive Drab Green]

They didn't look burned, they looked brown and wilt-y. They look burned if they have thermal burns.

 

[Yodaweed]

This is hash tip from too much light intensity, it didn't burn it , it literally turned it white.

Light Bleaching Cannabis Buds

This is how you get "albino" buds. Light bleaching is most common with high-power LEDs and HPS lights that are kept too close to the tops of the plants. Basically, this is what happens when plants get too much light, kinda like how hair on top of your head can turn lighter if you spend plenty of time in the sun, except a "sun-burnt" bud isn't as strong!

 

[Yodaweed]

I have done that before to my plants , too much light exposure to high intensity lighting can make your buds turn white like a weird albino weed strain.

I'm telling you it didn't have time to light bleach it. My flower light destroyed them. It was the light. More than likely, my UVs.

If it burned it and didn't bleach its not light intensity its heat, there is a difference. Over exposure to UV light will burn plants like a sunburn , also fries your THC turns it to CBN all ambers too quickly.

I'm telling 100% because you weren't there, this was light related, not nute related. I am positive.

Only a sith deals in absolutes.

Light intensity is an issue if the leaf temps are too high or too low. The factors that affect photosynthesis are pretty well documented.

 

[Dankonomics_genetics]

Gavitas and the high powered LEDs will bleach tops. The cheap LEDs you can put almost right next to the plants, but the expensive ones really have some intesity like the de hoods. I've burnt a top here and there too and it wasn't from nute burn but light intensity from my gavitas.

Nice.
