I've Got A Light Question

People have said that the HPS lights are more on the "Red spectrum" of light.
Would red saran wrap help make florescent more "flower friendly", until HPS can be afforded?

I'm not a light expert but I don't think it will make a difference, the light spectrum will be the same. The only thing your doing in my opinion is ruining your reflective light potential.

lmao! red saran wrap!!

if you're going to use CFL's and you're looking for the 'flower' spectrum.. get the 2700k CFL's.
do they even make red saran wrap? lol

I'm not using CFL, just FL. And don't have money to buy lights, that's the point.

Yes, they make red saran wrap.

whats an FL?
are you talking about T5's, T8's, ect.?

Yeah. Just regular Florescent lights.

I've got about 7-800W of FL on three girls. But it's mostly Veg light...

Unfortunately your source of light will be the source of the spectrum. Neat idea, but it wont work!

I really hope this thread is a joke. If you put red saran wrap over the light the only thing it will do is filter out all the light which isn't red. If you can't afford new bulbs or a new light just flower with what you have. It will work a shitload better than covering it in saran wrap.

Is today ask silly question day and I just didn't get the memo? Your posts can be a little strange, but intelligent.....this question isn't. Come on man....red saran wrap, really?

No it's not a joke.
And from what people say "Filtering out all the light that isn't red" seems like it would help, according to what people say.

My plants are stretching and flowering way too slow, people say they need a "reder spectrum" and filter or not, pure red, would be a "red spectrum"

Red plastic will make the light appear red to you, but it will also filter out and water down the other colors the fluoros have that the plant uses.

And plants use all colors between 400nm-700nm, and even outside that, just more of some colors are needed and not as much for others.

I'm not in Newbie Central, and admitting that I'm not sure of something. To ask Intelligent questions, just maybe get some intelligent answers

red spectrum is optimal but not needed for flowering. red triggers flowering hormones in the plant to get going, but isnt needed. i know of people who have flowered with a metal hallide with very good results which is a blue spectrum. do you know what spectrum you're lights are?

No, I know it's a bunch of t5's.

the red spectrum induces stretch.. blue spectrum keeps plants more squat. i flower the 1st three weeks of stretch with metal hallide

just use what you have and you'll be fine. not like you have much of a choice anyway lol

MH emits red too, just a higher concentration of blue. If there was a total lack of red, like of the color was cut off at 500nm, where it starts to turn blue to green, they plants will not do so good.

The color temps shown on MH, HPS, fluoros are full spectrum, covering below 400nm, and going above 700nm. The kelvin rating shows what the dominant color is in that bulb, thus giving off a whitish color with a hue of the color that is most dominant, which is why MH and 6500K fluoros have a blueish color to them.

when i say red and blue i'm speaking of the dominant colors obviously but thanks for the info
chicken soup isnt just chicken and broth.

you have to be reeeally stoned like me to get that metaphor

i see you're into LED's. nice i've been contemplating getting some LED's for a side grow of some autos.
