Green light safe or BS

I would like to ask anyone out here knows off or has ANY proof you can use green lights on ya plants n they don't react?after painting a low watt bulb green mon (I'm growing in uk in tent in shed mid winter so have to light at night to keep low temps away so I don't have much time to work on my grow so the green light would be great)once the bulb was done I thought "I know a few growers mainly gurillas but not one ef them have ever used one.now remember I want it to be true but two days of trying to find any scientific or anything but one man who swears about it? So pls HELP does it work or next week I'm gonna tell the community that it's not green it's yellow with black stripes that works n by the way I've got a product for sale!a headband light hand painted yellow with black stripes it cost £9.99 n called "THE BUMBLE BEE"???? Please give me your views. Smudge,keep it green "ironic"

Im pretty sure painting a light green isnt the same thing as a green light as it needs to be the correct spectrum.

get a small heater

But whatever spectrum it's still light? Please have you any proof?

I have one of those LED green lights that clip on a hat. It didn't caused a hermie on the one grow I did since I bought it. Not really "proof", but that was my experience.

Cheers but that's not the Q: + I've never found a htr even Tuva that doesn't cost more than 5.5pence an hour ,I use reptile heat pads they keep roots between 19c n 21c but this is not wot the thread is about!

There is new research out (and at least two threads already linked to it this past week on RIU) showing that the green spectrum of light is able to produce photosynthesis. I use green light for emergency night time issues and have never had a problem. I will continue to use it in this manner, but as sparingly as possible.

No, it's not the question, it's the answer. Are you confused about the thread? Here is the questioned you ask: "I would like to ask anyone out here knows off or has ANY proof you can use green lights on ya plants n they don't react?" What do heating pads have to do with green lights?

If you paint an incandescent lightbulb it will reduce the bulbs life span to about 1/10th of what the bulb is rated for. I would go with a small hair dryer with a thermostat. I have hair dryers in the op for making hash

It's winter in his country and he wants to use this painted lightbulb for heat in his op. I don't "think" it's a good idea. To unreliable.

I agree that painted light bulbs are a bad idea. Might also be a fire hazard. But his question was "I would like to ask anyone out here knows off or has ANY proof you can use green lights on ya plants n they don't react?" The only question. He should be more clear if he wanted an answer to a different question than the one he asked.

from what i understand green light is used in photosynthesis, but at the right wavelength it doesn't effect photoperiod
with that being said, I think it's a good idea not to use any light at night, just because i don't do anything I don't have to. I would use an LED at the right wavelength if needed, because i'm not sure how well those party bulbs work (though i've used one before with no ill effects)
i guess blue light is almost the same from what Ed Rosenthal says
ed rosenthal does a writeup on different light and how it's used http://mjgrowers.com/book_what_exper1.htm and suggest you "might " be able to boost yields with blue and green light at night. As far as i know nothing was proven and it's all thesis

why not get a space heater?

A heater with a thermostat is the ticket. Those oil-filled radiant heaters or a ceramic would be ideal. You want something that you can leave unattended without concern that it would get too warm or start a fire. I haven't had a need to supply heat to my grow room, just cooling.

I don't want to heat anything with the green bulb someone said buy a heater I told em of my pads then tried to get the thread bak onlinePeace

That is my view I'll buy a wasp or whatever there called n use it in emergency only until I find some *PROOF* peace

Recently I purchased a digital ballast that has a green L.c.d. display.(Solis tek matrix) my tent is light proof and the room my tent is in is light proof as well. I keep the ballast in the room not the tent. Anyhow ... I had to cover the l.c.d. because it was so bright. The entire room was lit neon green due to the ballast.
On the packaging and on their video it says "green LCD display as to not disturb your plants during lights off". I'm not saying this is fact but the manufacturer believes green light is ok.
I still covered the green display. C.Y.A.

I have a green fluro from lowes and use it everyday. I water before I go to work under greenlight and when I get home from work I go in there under greenlighy for a hour or so and never had a problem and been using it for 3 years now. Also my mini split lights are green my dehumidiy has green lights as well. I mean if you have a 400watt green bulb it might change tje scenario but none of my green lighysbhave ever cause a problem

Yes a green light bulb is safe and does not disturb the dark flower time. The color spectrum is not used for the plant during flower so it has zero affect on the plants night cycle. If you think about it outdoor growers never get total dark as the moon shines down but the intensity and color range is not enough to inhibit the flower cycle. Most green houses will also confirm the use of green spectrum lights in dark flower cycles. Don't paint a regular bulbthough as the paint can scorch and catch fire. Use something like this http://www.homedepot.com/p/Unbranded-100-Watt-Incandescent-PAR38-Green-Light-Bulb-12-Pack-100PAR-G-1-12/202499241?cm_mmc=shopping-_-googleads-_-pla-_-202499241&skwcid&kwd=&ci_sku=202499241&ci_kw=&ci_gpa=pla&ci_src=17588969 . If its more about heat then a simple propane tank with electric ignition top heater like this will work http://www.bakersgas.com/MRH4410569.html?gclid=CNynpd7fprwCFctcMgod9nYAUA ....or if you have an electric blanket you can make a pvc frame over the plants drape it over then top with one of those silver reflector blankets to reflect heat down on plants with a simple time to turn it on and off when you want

I thought it was common knowledge by now that you can basically leave green CFLs on the entire lights off period with no adverse affect..

I have a green led bulb up high, and a green led strapped to my forehead(what a fucking dork huh), when i need to work in my room at night time. I do it ALL the time, sometimes for many hours at a time. Oh yeah, many pieces of equipment with green led, shinning constantly. NO balls on my plants. When i was much younger, i would cut 7up or sprite 2liter bottles up to the same size lens as a flashlite. 3 thick. No herm issues back then either, but it would be just for temporary viewing. I heard that led green is the only legit green that doesn't do harm. I don't/won't use colored incandescent or cfl no more. Why chance it huh?
