Especially when there are adequate lighting in the aquarium, they will change the pigment in the newer leaves to absorb different light spectrum.
And only some species will turn red, not all. If want to stop the red from coming, you can always decrease your lighting...
Correct me if I'm wrong...

yes you are correct, different lighting condition will change the colour of the plants, ironicaly, different manufacturer have different light spectrum output due to the inner coating and manufacturing process. I have seen the results differs from cheap strange brand to good brands.

I totally agree with you on this, the only challenge is to get a casing that is suitable.
I could have gotten somebody to fabricate for me, but end up the cost is very close to the ones in the fish shop, if there is anyway we can make it ourselves I am all in for it.
My experience is that T8 ballast is very easy to find, T5 now is easy but T5 24W for HO bulbs is quite hard to find, PL ballast so far is difficult to find.
IMHO, a few hundred is too overpriced
