T5's - Full Spectrum?

Ok I found a good deal on a 4' Full Spectrum HO T5 setup that comes with 4 blue and 4 red bulbs which can be mixed. Now I am only planning on growing 3 plants at a time so I am thinking of using all 4 blue bulbs for veg, then switching over to all 4 four red bulbs for flowering. Now some people have said to use 2 blue and 2 red throughout the whole process of veg and flower, but I keep thinking to myself that having 4 red bulbs during flower will be much more effective for my yields than 2 blue and 2 red. If anyone could give me some good input on this that would be great.

Why not go 3/1?

You can do whatever you choose, research done has shown the half and half is best. All of the folks that work at my hydro shop are using a mixture of red and blue, so am I. VV

So VV are you using the 8 bulb setup, 4 red 4 blue? Also are you using any other lights other than T5's and how many plants do you have? And if you do use 4 red 4 blue do you keep them the same through veg and flowering?

Blue lights keep internodes short, so they are useful in vegetative phase to keep the plant squat. However, the pictures that I have seen, where people actually did experimental grows with different spectrum of light shows that 3000 degrees K lamps (red rich) gives the most abundant growth, more growth than even compared to outdoors. I think this is because of the shape of the chlorophyll absorption curve matching the 3000K (red) lamp the best. Chlorophyll responds extremely well to red light. Other (carotene) molecules grab the green light and transfer electrons over to chlorophyll. Chlorophyll has less activity with blue light. Blue light is sensed by the phytochrome pigment that tells the plant that it is "out in the open", ie, "not shaded", so it doesn't need to "reach for the light", the way it would have to if it were in the shade (which lets more red light through, and filters the blue out). So I prefer to use
the red lamps when flowering. Remember, just because it is red, this is just a relative thing, it still has enough blue in it to keep the plant from "reaching". It's just that the red photons are more "nourishing" for the chlorophyll, compared to blue, the chlorophyll is more efficient at converting it into "biomass" (ie yield is more).

The above post is for entertainment purposes only, as I do not grow pot and do not advocate breaking the law.

Yup, i have 2 blue/red. works great
