 Hi,
 I  just  wanna  know,  leaving  all  other  paraneters  the  same,
 which  is  more  suitable  for  a  Planted  tank  tto  grow  plants,  and  not  to  show  off  fish  colors?
 5000K  or  6500K  or  10,000K  in  T5HO?
 
 I  have  so  far  been  using  6500K,  is  5000K  better?  How  about  10,000K?
 
 Thanks  a  lot.

 Hey,  most  of  the  time  the  difference  in  plant  growth  between  these  3  would  be  negligible.  It  is  mostly  a  matter  of  what  our  preference  is  for  viewing  the  tank  so  if  you  are  happy  with  6500k  then  stick  with  those  as  they  are  the  "standard"  colour  for  planted  tanks.  If  you  want  you  could  get  a  5L  and  10K  tube  each  and  try  them  out  to  see  if  you  like  the  effect  and  then  change

 ...infact  I  am  hating  the  effect  of  the  5,000k  tube,  its  too  pink  for  my  liking.
 So  should  I  add  another  6,500K  tube,  or  a  10,000K  tube.
 
 I  like  the  6,500K  the  best,  I  have  not  seen  a  10,000K  tube  in  the  works...so  don't  know.
 
 But  thats  good  to  know  that  the  plants  don't  care  so  much...or  do  they?

 Well,  if  you  do  a  google  search  you  will  easily  find  that  photosynthesis   peaks  at  6500K.
 I  guess  it  would  make  a  difference  as  to  what  Kelvin  is  best  for  plants.
 Sunlight  is  a  very  complex  light  which  has  ton  of  wavelengths  in  it.  But  by  chosing  the  wavelength  best  for  plants,
 we  could  optimize  the  growth....  Given  a  good  light  like  T5HO,  it  wouldn't  make  big  difference  though.

 +1  with  Veeral.
 
 I  have  changed  my  aquarium  light  to  12000K  and  every  plant  in  my  aquarium  still  growing  the  same  way  they  used  to  grow  before  for  last  2  and  half  month...  And  with  12000K  damn..  you  need  to  see  to  believe  the  color  of  fishes  and  plants  ;)
 
 NB:  Theoretically  6500K  is  required  for  plants  to  grow  properly..  But  i  think  they  find  their  way  out  probably  with  any  light..  
 unless  its  UV   Very Happy   {Still  now  experiment  with  5000K-6500K..  it  looks  pale...  so  i  have  tried  mixing  with  a  blue  light  and  that  combination  also  works..}

 As  said  earlier,  if  you  got  a  very  intense  light  like  a  T5HO,  it  wouldn't  make  difference.  
 You  just  have  to  pick  the  light  which  looks  pleasing  to  you.
 There  are  people  who  got  pearling  just  be  switching  to  6500K(They  had  less  intense  lights  like  PLL  or  CFL  though)

 12000k  gives  denser  growth.  if  u  using  6500k,  add  a  blue  light,  and  see  the  effect.  my  moss  growth  is  thicker  and  greener......  iv  shifted  to  led  floods  but  there  is  1  tank  that  has  2   6500k  with  1  blue  t5ho.......

 I  doubt  if  you  will  get  a  conclusive  answer.
 Most  of  the  studies  which  are  conducted  are  with  terrestrial  plants.
 Further  plants  are  able  to  adept  to  conditions  to  some  extent.
 Experiences  of  aquarists  are  of  limited  value  as  conditions  in  each  tank  are  different,  and  unless  tests  with  strictly  controlled  conditions  are  performed,  it  is  difficult  to  predict  if  the  results  are  due  to  lights  or  other  conditions.
