 Hi;  
 
 1.What  part  of  the  light  spectrum  do  plants  needs  for  photosynthesis?
 2.Do  different  light  fixtures  produce  different  light?
 3.What  is  "K"  rating  means?
 4.What  does  6500K  means?
 5.How  does  one  measure  light  quality,output,from  a  light  fixture,does  quality  matter?

 superb.  Nice  tank  with  healthy  growth.  I  am  facing  an  issue  of  light  scattering.  I  have  installed  36w*2  PLL.  But  most  of  light  is  escaped  through  downward  direction.
 Please  post  internal  image  for  light  fixture.

 Ok  friends  presuming  that  you  all  have  read  the  threads  above,  provided  in  the  links,  I  would  like  to  demonstrate  the  same  thing  in  layman's  language.
 
 As  you  can  see  that  there  is  a  good  difference  in  lighting  in  the  above  pictures.  
 
 But  the  major  focus  is  on  good  growth  (thick,  dense  growth)  greenery  and  wherever  colour,  it  should  give  immense  satisfaction  in  the  efforts  put  towards  it.
 
 We  buy  plants  from  various  vendors  and  especially  the  red  plants  would  simply  turn  green  or  die  off.  
 
 we  also  have  to  play  with  fertilisers  to  keep  up  growth  and  fine  tune  the  colour.  Needlessly  these  efforts  remain  limited  in  output.
 
 So  how  does  lights  effect  the  plants?  
 
 How  does  fertilisers  work  in  different  types  of  substrates?  
 
 How  does  colour  show  up  with  all  these  combinations?
 
 
 Breaking  the  Red  plant  codes  Cheer  
 
 we  normally  use  lots  of  light,   (I  mean  many  lights)  all  are  those  6500K  Very Happy,  some  are  cool  daylight,  some  are  plain  white,  some  are  just  not  known.  
 
 all  these  lights  are  white  tubes.  (of  course  there  are  also  coloured  tubes  Smile  )
 
 these  lights  are  glass  cylinders  filled  with  certain  gases  and  current  is  passed  through  it.  
 
 when  current  passes  through  these  gases.....,  these  gases  blow-up  to  glow  brightly  into  light-  almost  like  Sunlight........  the  sun,  as  we  know  gives  out  rays  which  have  colours,  
 
 In  man  made  lights,  1)  the  brightness  is  strong,.....  2)  then  stronger  and.....3)  then  strongest-        So  15Watts........18watts...........28watts..........36  watts  etc  etc.  
 
 The  electric  current  has  two  things  1)  Voltage  =  its  the  strength  of  the  current  (How  sharp  the  current  is),        2)  Wattage  =  its  the  thickness  of  the  current  (How  FAT  the  current  is).  
 
 its  like  a  pipe  throwing  water-  a  5mm  pipe  will  throw  little  water  in  1  min......  a  3inch  pipe  will  throw  lots  of  water   in  1  min  (something  like  that)  water  is  constant,  but  the  thickness  is  different.
 
 6500K  lights  will  glow  at  all  watts-  but  the  light  will  reach  at  different  lengths/distances.  15Watts  will  reach  up  to  3  feet  (just  for  understanding)  and  36watts  will  reach  6  feet.-  that  is  called  the  intensity  (  for  the  time  being  to  understand)
 
 But  then  As  I  mentioned  earlier  lights  have  rays  and  rays  have  colours-  
 
 so  in  6500K  there  are  many  colours-.........Red,  Blue  Green,  Yellow,  etc  etc.  
 
 6500K  "K"  means  Kelvin,.......  its  a  measuring  unit  -........  Kelvin  is  a  "degree"  of  heat  like  Celsius,  Fahrenheit  etc
 
 here  the  lights  have  various  coloured  rays-  .....red  will  be  about  9%,......  green  will  be  about  60%,.......  blue  will  be  about  20%,.......  yellow  will  be  about  10%  ..........and  the  rest  of  the  colours  in  different  %percentages.(  its  called  CRI  colour  rendering  Index)
 
 this  light  is  manufactured  in  such  a  way  that  human  beings  enjoy  the  brightness......  Human  beings  like  green  colour  rays  which  is  soothing  to  the  eyes  and  comfortable.  It  was  therefore  made  for  home  use.   ROFL  
 
 All  those  gases  filled  in  that  18"  glass  cylinder  reaches  6500K  white  light  (approximately  500  lumens)  and  brightens  different  area  of  rooms  depending  on  the  wattage-  "Come  ooooon  we  all  know  that  Thumb Down"  yeah  I  know.
 
 Next  chapter  after  you  read  this  ROFL

 The  colour  we  see.     The  word  "SEE"  Chuckle   
 
 Plants  don't  have  eyes.........what?  Banned  Ya  they  dont  have  eyes.,  then  how  do  they  see  colours   Confused   Well  actually  they  don't  see  colours,.........  they  feel  colours.........  the  word  "FEEL"'   
 
 Even  human  beings  feet  colour  heat  check  the  strobe  light  Chuckle  (disco  huh),  the  Xrays  Surprised  all  these  lights  which  glow  at  their  highest  with  all  intense  colours  is  a  full  SPECTRUM
 
 so  even  colours  have  intensity-  
 
 check  it  yourself-  open  paint  in  windows  >  select  a  colour  in  the  palette>  click  edit>  and  see  .  
 
 The  colour  is  set  from  darkest  to  the  lightest-  lastly  all  end  up  into  white-  Smile  
 
 Plants  make  their  own  food,  whenever  they  are  hungry,  that  is  called  photosynthesis
 
 Photosynthesis-  Calvin  cycle-  Plants  take  in  light  and  convert  it  into  chemical  energy.  .......so  that  only  makes  them  green......  how  do  they  turn  red?
 
 Well...  first  plants  take  water  and  carbon  dioxide  and  then  minerals  from  soil,  then  mix  it  with  Light  to  create  sugar  and  throw  away  oxygen.  The  light  hits  again  and  again  and  again-  yeow  Shocked  
 
 read  these  also  http://extension.oregonstate.edu/gardening/colored-leaves-have-chlorophyll-too
 
 When  the  rays  keep  hitting  our  aquatic  plants  from  our  man  made  tube  lights,  they  also  photosynthesize.  
 
 So  they  absorb  the  blue  and  red  and  a  little  green  and  reject  the  rest  and  stay  healthy.
 
 BUT  they  are  still  green....   Doh  
 
 WHAT?  Jester  
 
 read  the  link  I  will  explain  that  too  Next  Chapter  Cheering

 PHOTOSYNTHESIS
 
 In  the  Nature  zone,  as  mentioned  above,  its  all  simple.  But  in  the  Tank  its  complicated-Our  plants  are  aquatic  plants-
 
 They  are  in  huge  amount  of  water.  In  nature  the  lights  are  bright  and  have  a  large  area  coverage  capacity  and  fall  directly  on  plants.
 
 But  when  light  penetrates  through  water  is  gets  SHADED.  whether  it  be  in  nature  or  tanks,  light's  power  to  shine  becomes  low  when  placed  above  water.
 
 Therefore  our  plants  are  more  sensitive  to  light.  They  sense  light  very  fast.
 
 The  plants  have  3  types  of  cells
 
 1.  Chlorophyl  -  green
 2.  Carotin  -  Orange
 3.  Anthocyanin  -  Red
 
 REFLECTION-
 
 Place  a  white  foot  ball  in  a  dark  room-  and  show  a  yellow  bulb  torch  to  it-  It  will  glow  as  yellow  ball-  If  we  show  a  white  light  it  will  glow  white-  If  we  Show  red  light  it  wiil  glow  red.
 
 All  this  while,  we  are  shining  different  lights  upon  the  white  ball  and  we  see  the  ball  in  different  colours-  "WE  SEE"
 
 When  the  sun  shines  on  plants  they  reflect  green,  orange,  red.  and  its  variants  like  in  PAINT  SOFTWARE
 
 these  3  colours  are  considered  are  pigments-  read  the  link  in  the  second  chapter-
 
 So  when  we  consider  the  white  lights  we  have  to  consider  what  colours  they  emit/throw-
 
 Our  white  lights  should  have  more  Blue  and  Red-  Since  we  can  not  tweek  the  white  lights,  lets  add  a  blue  light  and  a  red  light-
 
 Now,  by  adding  these  two  lights  we  have  we  have  given  the  Brightness  which  the  plants  absorb  and  reflect  the  same  in  their  capacity  for  us  to  see  in  colours.
 
 These  lights  when  shine  together  in  a  combination  will  reach  the  right  Kelvins.  So  right  heat-  so  right  colour  capacity,  so  3  different  reflections  from  plants-  
 
 The  rich,  intense  and  lush  colours  appear  to  the  human  eye  reflected  by  3  different  pigments.

 @Kapil  lift  the  hood  about  2"  higher,  there  is  too  much  intensity.  You  may  get  algae  very  soon  despite  of  co2.
 
 there  is  lot  of  water  flow  if  possible  slow  it  down
 
 buy  RBG  led  strip  and  intensify  the  blue  and  red,  suppress  the  green,  it  will  suit  your  set-up.  Those  swirling  of  plants  will  stop  and  you  will  get  straight  stems,  after  you  install  RGB  led  strip
 
 its  18X12X15  I  suppose  with  aluminum  foil   Smile

 Are  you  sure  to  lift  hood  ?  
 because  using  only  36w  pll  now.  And  the  plants  are  h.pinnaetifida,  ludwigia  repens,  bacopa  monneiri,  green  mint.  So  i  think  this  much  is  must  needed  for  these  plants.  Willing  to  make  DIY  LED  hood  soon.
 I  need  few  cuttings  if  you  have.
