Red light has an increased rate of photosynthesis then white lights.
i took my 15 ltr tank and put in some hornworth (wrong spelling ?) and the light from the tube went through a red celephane (wrong spelling?) (again lol)so that only red light got through. i am now see ing if these plants in red light grow faster then the ones in my tank. What do u think?

Im not sure if it the colour that causes the growth but rather the light spectrum used. I use a high intensity 'full colour' UV that is used to bring out colour in fish and grow corals etc along with a 'Plant light' that gives of a reddish glow. If you are very interested in plant then a double reflector is always a very good way to go, usually with a combination of bulbs. cant not help to experement though.

yes, the spectrum contains red aswell but is it is to be a full spectrum it must have green which nearly stops photosynthesis. there are a few other colours that also are no good for photosynphesis. for example lets say i had a light that gave out green and red at the same time. the plants will be exposed to red light which speeds up photosynthesis but also green which slows t down so you get an avarage speed for photosynthesis,
the red celephane absorbes all the other colours and lets only red through so the plant is only exposed to this one colour. Do i make myself clear?

as in full spectrum 'natural' light? I always thought the more high intensity the light the better. Wouldnt the ammount of light being blocked by the cellophane be detremental even if it was filtering out the other colours?

yes, it does decrease the intensity of light. if this is what you mean.
