Entering the Growroom at lightsout

someone hasn't had there smoke break today a green light work just fine. I got one of those dorky green led head lamps I purchased from my local toy store= grow shop

enough guys. good luck.

Guess there was no link.

link to what? sorry missed your post on the link. I'll see what I can find for you. So with this train of thought I should use red and green cfl's in my grow and not worry about the 6500k for veg and the 2700k for flower?

i use a green led flashlight and it works fine. I'm not a professional on this but i would think a green spot light, cfl, or whatever hung atleast 3 feet over the plants would give off such a small amount of usable light that it would not effect the photoperiod.Some people use blacklights during their darkperiod because they think it does something special, idk but i dont think blacklights would hurt either.

I think you should do what i do. Remove the males and experiment on them. Try green cfls' ,LEDs, blacklights and green spot lights and see what happens to the males. I also use them to test fertilizers and what not cuz i dont really care if i burn the males lol.

This might help. might not.

I was headed that way. But want to help this guy understand how light works. I still don't like useing any light that will affect the plant in flower. as for searching. try how light works. you'll be able to read for days. good luck.

Didnt this whole thing start out as a question about some light during the dark cycle so the guy could go in and do some work? Now you have somehow turned it into something about growing with red and green CFL's. We are talking about a few minutes of dim green light. One question for you stumps. How can you breathe with your head so far up your ass??? I am bored now. Bye

Yes, thats percisely it.

It was fun. I guess.

stick with the greenlight ill tell you from expirience it works fuck the bs....and here is the fact

Does the color green of light affect plant growth?



No, plants reflect the wavelength of light we perceive as green. In order for light to be useful to a plant it has to absorb the wavelength.

Nice find. I've never seen these studies. This adds credit to to the green light. I'm not 100% on what it is saying. I would like to see more on the other studies that where refed. I'm not saying they are wrong but I would love to see something a little more updated. most of those studies are older then I am. I only say because of the leaps in science. "Edit"Sorry there are more updated in there.

I've used a green light in the grow room for years without incident with a few different strains, but I've also seen plants seed themselves too. Whether or not the green light work done during the "dark hours" was responsible for the adverse effects remains debateable. Personally, I don't even take the chance anymore. Unless you can afford the possibility of these type of problems I'd stay away from them. George Van Patten wrote a book about growing indoors and it had a small section on this subject saying that phototropism was most affected by what color spectrum the most? You guessed it.....green light.


The question still remains though, is phototropism during the dark period a bad thing? Being that it's probably not natural probably not, but the industry greenhouse standard for "lights out" is supposedly zero lumens. What that actually means is, you could actually still be able to read a newspaper in the room during lights out and the plants not be affected. Personally, I'm done rolling the dice. Take your chances if you want though. *2 cents*

i can always put a hood on the light to make it so the light is more so directed at the ceiling of the grow room marther than reflecting it down toward the floor, could that work? or do they have a glass bulb (like those on ceiling fans) that i can affix over the light fixture to help diffuse the light enough to make it so the plant cannot use it, but i can still see?

would these ideas work??

some one said it. Try it and see. some guys say green is the thing to use. and if its low watt you might get away with it. if not you'll know next time. zero light is most critical the first part of flower. Good luck with what ever you do.
