he hank, im a noob so dont take my word on this. i do THINK that painting your walls red or orange wouldnt be practical for your plants because this is the only spectrum(s) of light that would reflect off your wall(?).... other spectrums would be absorbed by the red/orange wall that might be benificial to your plants(?) and white reflects up to 95% of ALL light, i think.... for example the reason why plants are green because they absorb other spectrums of light but reflect green(?). and green does nothing for a plant(?),....... ummm ya.....the reason for all the "(?)" is because im not doing any research right now but going off of my little knowledge that i think i know about light lol.Why not paint our growing walls orange an red instead of white? This of course would be during flowering.

That filters the light - reducing the light to emit only the spectrum you want. But that will cut the overall light by as much as 80% or more.if the colour of the light matters, why not paint the bulb with glass paint?
guess it would decrease light a lil, but shouldnt b too much if u use thin paint...That filters the light - reducing the light to emit only the spectrum you want. But that will cut the overall light by as much as 80% or more.
You want the light to PROduce the spectrum you want, not REduce to it.
hey stonegrove! i think that a key point he mentioned is "You want the light to PROduce the spectrum you want, not REduce to it." they sell special horticural lights that have alot better spectrums than your standard hps bulb. instead of buying a cheaper bulb, if you buy a more expensive one they usually have a graph of the light emitting spectums/PAR(?). and you can base your purchase on this if you want to get scientific. from what i've read, anything that gets in the way of your light and your light hungry plants doesnt seem to be good, even if its just crystal clear glass. well unless your using a "cool" tube then the small decline of light out weighs the benifits of efficently removing hot air. God bless everyoneguess it would decrease light a lil, but shouldnt b too much if u use thin paint...
