when a plant is asleep, doesn't endure light from the moon. so what constitutes has too much light?
That's a popular misconception seemorebuds. The fact is:seemorebuds302 said:yes you can use green light bulbs in your grow area b/c short day plants do not respond to the green of the spectrum.
If you research Dr. D.R.Hershey and then use "Green spectrum" as another search in the results of the first search, you'll discover that he is prompting all of the people who write text books to change the information in them to include his findings. His research has been proven. It's no longer being verified, it is verified.seemorebuds302 said:huh dude thats really interesting cuz i saw on george cervantes ultamate grow dvd he said you can use green and i just picked up gardening indoors by george van patten and it said the same thing infact i quoted it in my last responce. I would think cerventes would know that????
I hear you GDG, I had a small light leak during my last grow of Big Bud and the plant that was on the side of the light, Hermied bad. The other three plants were safe tho because of the density of the jungle. Wheeeew!GreenDayGirl said:The way I see it...when those lights go off for the night. Thats it. There is nothing in there I can't live without until the morning. Light leaks, "hermies", I speak from my last experience.
thanks for the info stoney, very interesting.Stoney Bud said:If you research Dr. D.R.Hershey and then use "Green spectrum" as another search in the results of the first search, you'll discover that he is prompting all of the people who write text books to change the information in them to include his findings.

Even some of the top universities are teaching this topic incorrectly. It's not surprising that some of the people selling DVDs and books haven't updated their own information.
Now, it goes way beyond "Plants use Green Light". The part of the green spectrum and the intensity of the light also have a lot to do with the use of the light.
Also, with weed, it depends on the strain of the weed, it's health, it's age, it's transpiration rate, light, nutes and other factors.
During flowering, MJ produces a chemical that promotes the flowering and how the flowering happens on each part of the plant. This chemical is light dependant. (Without digging it up, I don't remember the name of the chemical. If you want to know it, I can find it for you.). If light of an amount that can be used by the plant reaches the surface of the plant, it will cause changes in the flowering cycle. If that light reaches the surface of the plant in significant amounts during the "dark" cycle of the day, and lasts long enough, the plant will "see" the light and will alter it's flowering chemicals to adjust to the "new" season.
This can cause the interruption of flowering in the worst case to causing a Hermie or delaying the completion of the flowering cycle in the best case.
The intensity of the green light is the key factor in this. You may be able to use a dim green light with no harm, but it would be your experiment. It may screw up your grow.
I would suggest NO light during darkness cycles each day of the flowering cycle. Better to be sure than sorry.
Good luck to you man.
