Re: Red vs Blue Lighting


Red makes plants grow up, blue light makes plants grow bushy.  It is possible 
that you have a different species of Vallisineria, as there are many.  
Possibly it is a contortion val or an Italian val, but I don't think either 
of those is supposed to get to 42 inches!  How many bulbs are there on your 
tank?  Plants need that red spectrum, so possibly instead of replacing it 
with a blue one, could you just add a blue one?  On my tank, I have two 
reddish bulbs and two "50/50" (half actinic) bulbs that give out a small 
amount of blue light.
