Green LEDs cause hermies?

[Power OG]

so its meant 2 b a way of using a light without it causing leaf burn then??

no i think its a way for them to see, so they can foliar feed when there room is in dark.

 

[dogznova]

Where is 619ster on this... Green light during the night time of flowing can and will pull some strains right out of flowering if left on for too long and def will cause hermies on weak strains if they get to much green light exposure..

The only proven spectrums that won't pull your girls out of flowering or cause hermies when working in the flowering room during the dark period is above 530nm.. Not sure where the grow stores got this false info and started selling green led for dark time flowering room work, but avoid if if you can.. Get yourself a RED cfl from home depot for nigh time flower room work and never worry bout causing hermies or pulling your girls out of flowering again.

 

[Seamaiden]

Red? But... what about phytochromes?

 

[baba G]

how do you figure RED? There is a reason Green is the color we see when we look at the plant, it's not absorbing it but reflecting it...

Now is the green led letting white light out?

I've used a green incandescent with a fixture around it that I taped with green tape, used it for several years with many foliars and whatnot. Now the newer LED at the growstore, saw one in a room last week and it was WAY too bright!!

 

[PButter]

Green light seems to do fine over here. I'd be very interested to hear that your plants don't absorb RED.

 

[dogznova]

Full bloom flowers can absorb pure red light (660nm) all they want during night time flowering and it wont pull them out of flowering at ALL or cause hermies. It WILL however slow down the flowering internal clock if left on longer then 30 mins a night.. and 15 mins a night for example of pure red 660nm or a red cfl party bulb wont do a damn thing except let the grower go into the room to get work done :D .. I used 15 mins a night just as an example. Here is a better one.. A grower could use pure RED 660nm or a RED cfl party bulb 1/2 hr to 1 hr a week in the night time flowering cycle and the plans won't miss a beat. But use Green if you must..

Her is a nice little trick to try.. If that green light wont harm your flowering night time cycle as you say. Run a green light the full 12 hrs of darkness, heck run it only 6 hrs if you like.. I Bet after one week you will never use a green light again during your flowering night time cycle.. And Yes a grower can run pure red 660nm or a red cfl party bulb the full 12 hrs of darkness and it wont revert your plant back to veg or cause hermies. However after time ( a week or two) it will SLOW the plants flowering cycle way down.. My point is yeah it might slow them way down on a 12 hr pure red night time cycle, But it wont pull them out of flowering or cause hermies. Green light, not so much.. If you try this trick just be warned with that green light being on 12 hrs of your plants flowering dark time or even 6 hrs of their dark time WILL and I repeat WILL pull your plants out of flowering.. Try the same thing with pure RED 660nm or a RED cfl party bulb, results will not be the same..

Obviously you guy's are not running your Green light 12 hrs of the darkness, that is just for the example above.. Yes it's exaggerated but the results will show real fast.. But (you ask) how much Green light on time during the night time flowering is needed to pull the girls out of flowering or cause hermies? Unfortunately and I hate to say it.. It's strain dependant, which is why I always stay away from green light during the night time flowering cycle. Just trying to help..

The reason I keep saying pure red 660 led's is.. The china made led's that say they are 660nm or even 630nm bleed blue light through (hence will cause the plant to revert to veg or turn hermie).. So as I stated in my first post it's best to stick with a RED cfl party bulb right from home depot it's much cheaper and easier for the average grower to get their hands on..


So the moral to my story is.. Using red light for lets say 1/2 hr to 1 hr a week to do work during the flowering night time schedule is MUCH MUCH safer then using Green light for the same amount of time.. yes 10 mins a week with green light will not harm most girls.. But why take the chance.

Baba G. To answer your ? 530 nm's and up is the lowest spectrum to be found to not effect the flowering cycle other then slowing it down. Any spectrum below 530nm's will cause a re-veg of flowers or hermies if used for to long during the night time flower stage.

Green light falls below the 530nm threshold and will revert flowers back to a veg stage if left on long enough during the night time cycle.

 

[thump easy]

i so believe that but i cover ever fucken geen light from my split system to my chillers to my ppm meter i to am supper religous about that fucken light on at night and yes i noticed when i use a green light at night say my water mumps start moaning because the fucken res is getting swallowed up.. i get home i can hear them cry i have to get in thier to fill it up.. i also came to another conclusion CAN THE REFLECTION OFF A GREEN LIGHT REFLECT WHITE OFF OF A WHITE WALL????The reason i say this my chiller has a green light that blinks out of the back taken humidity readings and i swear i can almost see it reflect white of the panda film??? if i had a way to read light id so try it.. im gona open the chiller up and manualy make a box out of steel i usto be a tin Knocker and cover that sercut board that has the light a lil foam insert to cushin the into the cords out of the cercut board and block that shit out.. but this round i had a few herms just a few on some of my stable strains the ones nearest that chiller?????? its happend every single round since i put that dehumidifier in did i say chiller i ment dehumidifier!!!!!

So the best time to Spray the Plants no matter what is just before the lights go out, So if I put up a 60 watt regular CFL turn that on the start spraying the girls, then the lights turn off and I have about 10 mins worth of spraying to do with that little 60 watt light on so I can see around, is that going to matter ?
I'm also saying that the Green LED's from the grow stores are FUCKING JUNK AND are causing HERMIES !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!:mad::mad::mad::mad::mad::mad:

I've been using an Autopilot CO2 controller. Went into my room the other night and noticed an orangeish/reddish light blinking on the inside of the sniffer. Shit was a like a caution light blinking on and off all night in the room. I called my local store and he got on the phone with Hydrofarm to which they said that they had brought that to Autopiliots attention when they (Hydrofarm) purchased it but was told the light does NOT effect plants. Well it does effect plants and I've gotten in touch with one of the designers at Hydrofarm and am waiting for his proof that this damn blinking light doesn't effect plants that need total darkness. I've solved this issue in the meantime by putting the controller on a timer, but the more I think about it the more I wonder why the fuck I should have to put a 400$ controller on a damn timer...they need to fix this shit. So to anyone usuin an Autopilot CO2 Fuzzy Logic controller beware of the light! MGG

Depending on how strong that blinking red light is.. Red light will only slow down the internal clock.

Anyone that want's to prove to themselves that your plant will and I repeat will flower using red light during your dark time (530nm's and up) .. Try this simple test.

Get yourself 3 or 4 red cfl party bulbs from any hemp depot. Take a clone that has been rooted and put it under just those red cfl party bulbs on 24hrs of light.. Yes I said 24hrs of light. Plz come back in here and post your results.. Of course I already know the results.. But plz feel free to try it..

Wile your at it.. Take 4 Blue cfl party bulbs and do the same with another clone in a separate room. Put them both the red cfl party bulbs and the blues on a 24hr lighting cycle... Wait don't bother with the blue light we all know that wont do nothing but veg a plant.. Sorry for sounding like a smart ass but I'm just trying to make a valid point. Again the blue light is not a part of the test other then mental. Just trying to get you thinking.

But after the RED light test results are in you will have many many questions as why it vegged for a wile and then flowered under those RED cfl party bulbs on a 24hr lighting cycle.. Now if you have enough patients to let her finish.. You will find the plant will be small but the potency is through the roof. Of course this takes the clone aprox 6 months to finish, but my point is red light does very very strange things. But one of them is not causing hermies or pulling your girls out of flowering..

If you would like to find out more about red light and it's effects on the darkness.. Try googling PAD lighting. "Photo Synthetic Artificial Darkness" Unfortunately in the past yr or so.. It looks like
university's are trying to make fuel using photo synthetic artificial light. So only bother reading the stuff that pertains to the MMJ plant. Otherwise you'll be reading how to make fuel instead of how to make more potent girls.. :banghead:[

Just trying to help..

 

[Mr_GreenGenes]

The blinking light is not a true red...more of an orangeish red. And besides that why the fuck would I want to slow down my flower room production at all? Just not sure what your post has to do with my issue on the Autopilot controller. Fuck it if its time for em to sleep it should be DARK. MGG

And I for one I'm glad that your helping with this info about red light:), I have been trying to figure out what was wrong with my setup. Nothing I just started using them Green LED's about 6 months ago and have been having problems with shit going south, it was them Green lights, no doubt about it...:banghead:

 

[larebowm]

fucking green lights wow. i wired a socket to my breaker panel for a ""grow room green led"
and it took 2 extra weeks to finish and it never did finish quite write.
damn i bought right into that shit..
red light only when i go in from now on

@@dogsnova.. i do believe youve just saved plenty of people some grief.
everyone should know about this.

 

[Myco]

I use a Sentinel fuzzy logic co2 controller with a "plant friendly" green LED readout... I was very skeptical at first, gave it a chance, and after 4-5 runs I can say I don't feel this unit has caused any nanners.

But for the last 6 months or so I've been meaning to put it on a timer just to be 100% certain.

If possible, foliar right before lights out. Done. It takes long enough for burn to occur, and also if you're using a good surfactant, it lessens to chance rather than letting whatever you're spraying bead on the foliage.

Most folks rooms aren't too massive to pull it off...

I think there's a lot of options to exhaust before resorting to any sort of light disrupting the dark period...

Good vibes and happy, nanner-free gardening to all :)

So what I'm hearing from all this is that some cheapshit, two-bit, jerk company started selling some cheap crap 'green' lights that actually spill out any number of non green wavelengths. You are absolutely correct- don't buy it, don't use it. But then it seems we've gone away from that completely and are now telling people to buy Red spectrum lights - without any consideration of the cheapshit two-bit crap company they are made by.

Lets start over- buy yourselves some quality green lights for after hours work. Anyone care to recommend a quality green bulb?

X2, I'm just over it. with all the cheap ass shit that's sold at the Hydro stores, I just laugh when I walk in the doors at theses places anymore, there more Shit the you can shake a stick at, that you will never need or could use..LMFAO ...:rolleyes:

 

[PButter]

Yeah, for real- they weren't happy enough making 200% profit on some green light three years ago- had to switch it up to some 'green' light that makes 4000% profit. fuckers.

 

[dogznova]

Well the only reason I said RED light is.. Because even if you use high dollar GREEN lights.. The spectrum of green falls below the 530nm threshold and therefore will pull your girls out of flower if used with to much intensity and causes hermies. Again if used to much.. 10 15 mins a week with a real low intensity and most strains won't mind. But why take the chance is all i'm saying.

The red cfl party bulbs sold at hemp depot are cheap and easily accessible and they don't bleed blue light.. Better yet you can find real dark red reptile ones at the pet store. Yes they cost a bit more like $4 more but it's even a better quality bulb.

That's the problem with the green LED's.. They bleed blue light.. But it dont even mater they are in the wrong spectrum to begin with for flowering nighttime activities. Two problems wrapped up in one nice little package. Good Job Grow Stores.

Just tryin to help a fellow grower that needs to get a little work done in the dark time of flowering..

Yes cover all lights on controllers and/or PH/ppm wall mount pins with black electrical tape and make sure your room is in complete darkness at lights out. Then never disrupt their sleeping. Your doing more harm disrupting their sleep then good with the Foilar sprays.(unless bugs or pm) point being I hate being abruptly woken at 3am or anytime I'm sleeping. Plants same same. The info on the correct par/nm ratings for cannabis is correct but I still let them rest undisturbed for 12 hours.

 

[Mr.Metal]

I've been told that it's the wattage that you need to worry about with the green bulbs, "below 3 Watts shouldn't interfere with growth."

I use a green led hat clip just to be safe. And it's not very bright but it's sufficient for working on an individual area.
