green light for working in grow room at lights off?

[daybreamer]

hey there, if any of you guys have useg a green light without any problems in flowering could you put up a link to help me out? is it just a bulb coloured green or a light that only emits light from the green spectrum?

thanks

I just use a regular green party bulb found every where... They even have them in cfl for energy conservation... Or money conservation whichever you choose... I think my local grocery store carries them. Keep in mind I only use it when I need to workwith the lights off/dark hour I try top take care of needs with lights on..

Good Luck,

I don't buy the whole green light bulb thing. Wouldn't be surprised if you replaced the green party light with a red one and get the same results. I could be wrong but to me it just sounds fishy.

Red light = hermies and flowering problems. Green light is A OK!
Try it out..

Fuck that lol.

Rabbi, you don't have to buy any thing... Its not for sale... Knowledge is sharing experience, wisdom is listening... hey mabey your right, try it out prove us wrong... Good luck.

?...Well considering I don't think even having a green one on is a good idea, I'll go a head and get right on that for you.

 

[Diesel dreams]

Well considering.... you have brought a whole bunch of nothing to contribute to the mans question other than the fishy smell, I will gladly wait for the results of your red light special... Thanks for stepping up. Way to be a team player.

Which part of this didn't you understand the first time you asked?

I've read conflicting info on this. Seems that not all green light sources are created equal. Chlorophyll does not absorb the green wavelength, however "green" (or shades of green specifically) are not a single wavelength.

If I recall, the specific wavelength that is not absorbed is 530 nm, but don't take that as gospel.

I try to do any mucking about during flowering just before lights off myself.

However, If you must muck about during lights off and use a green light, keep exposure time as short as possible

I go in my room with every day with a red lense or with regular light to empty my A/c water and never get hermies.


IME as long as you keep the light low you shouldn't have any problems.

My point exactly. Not saying the green party bulb doesn't work but saying it's likely due to the low amount of light just like any dark colored bulb(like red for example). Do green colored party bulbs actually give out green spectrum?....doubt it.

 

[Diesel dreams]

Point well taken... What if the sticky I blunted helped me to forget that red, white, blue our any plant loving light spectrum low wattage or not was left on through a dark cycle or more....could possible ruin a plant or not. I wouldn't recommend anything but the green light for work thathas to be completed when light are out. I would recommend to keep the dark without any light though. Every garden is different.

Couldnt agree more brother.

Green Light

The visible green light has a wavelength of about 510 nm. Grass, for example, appears green because all of the colors in the visible part of the spectrum are absorbed into the leaves of the grass except green. Green is reflected, therefore grass appears green.
Lighting Spectrum and Photosythesis

The most common mistake people make with plants is to not understand photosynthesis and the visible spectrum of lighting that affects plant growth. Most people choose lighting solely based on the Kelvin temperature of a bulb. This tells you very little about what type of light within the spectrum is being emitted and at what strength. Visible light is on a scale in nanometers (radiated wavelength) from 400nm (violet) to 700nm (red). Simple matter of photosynthesis: plants can only utilize light that is absorbed. Bright light is essential yet only a portion of this white light is used for photosynthesis. The blue and red zones of the visible spectrum are the most beneficial to plants. Green plants appear green because it is reflected light. How “bright” a light appears has more to do with how much light is output in a given area visible to the human eye, with “brightness” being at a maximum in the green spectrum (middle of visible spectrum, or around 550nm).

Lighting for a growing plants should not be chosen on color temp alone. It is true that ‘full spectrum’ bulbs are referred to as bulbs between 5000 Kelvin (K) and 6500 K and are considered to be best for plants. Yet this does not indicate what wavelength in nanometers the bulb is actually emitting. If you want to optimize plant leaf development (blue light) and stem elongation and color (red light) you need light in both the blue and red spectra for photosynthesis. You need a mix of blue and red for your plants, and green for you (brightness as perceived by humans). If your lighting looks extremely bright and your plants seem ultra-green, it means that you have lighting that outputs strongly in the green spectrum. Do not equate this with good lighting for your plants, because plants don’t use light in the green spectrum for photosynthesis.

A green light and a green light bulb are not the same thing.

 

[daybreamer]

thanks for all the input so far, it would be for emergency use only so from the above it should be ok?

 

[Crusader Rabbit]

The light spectrum needed for photosynthesis and the light spectrum involved in initiation of the flowering response, are not necessarily one and the same. People who have investigated the flowering response have found that it is triggered in cannabis by an absence of light within the red wavelengths. This is what is likely involved in the stress/hermaphrodite issue.
