now in theatre, on the spotlights they have color screens, to allow only one color light show... since the plant needs red sprectrum, can't we use a red color screen?? they're the same screens used in the 3-d disney movies that come out in the theatre wit the red n blue movie goggles.. they filter out all other colors that only red or blue comes out.. can't we do the same with the plants??



the way i see it.. say we have a fullspectrum cfl tube.. can't we use the screen over it to make sure only the desired color range is discharged??
