AN INDOOR FARM TO HELP SOLVE FOOD CRISIS

A  JAPANESE   HAS  Turned  a   former   semiconductor   factory  into  one  of   the  largest  indoor  farm  ,cultivating   lettuces  with  Led  lights.This  farm   opened  in  July  is  churning  out  10,000    lettuces  head a  day.        
The  person  behind  this  project  is   plant  physiologist   Shegeharu   Shimamura   wanted  to  grow  good  vegetables  biologically .The  whole  process   is  scientifically   monitored .The  climate  control  room   is  powered  by  LED fixtures  that  emit&n bsp; light  at  wavelengths -  most  ideal  for  plant  growth-  while  also  giving 'farmers'    power to  control the  night  and  day  cycle.
Purple  lighting    is  used  to  mimic  night, for  example ,  while  white  lights  are  adjusted   slowly   through out  he  day   to  mimic   a  sun  moving   through  the  sky.
The  lights  were  built  by  American  multinational   General Electric  (GE). The  aim  is  to  achieve  the  best  combination  of  photosynthesis  during  the  day    and  breathing  at  night  by  controlling  the    lighting  and  the  environment.
The  lights  gives  them  the  ability  to   control  temperature, humidity,  and  irrigation ,  allowing it   to  cut  its  water  usage   to  one  percent  of  that  needed  by  outdoor  fields ,  while  growing  lettuces  two-and-a -half  times  faster ,  the  expert  claim.
The   system  allows   to  grow lettuces   full  of  vitamin   and  minerals.The  farm  comprises  of  17,500  LED lights  on  "18  cultivation  racks  reaching   15  level  high ,"GE  says.
The  farm  is  situated  in  the  Miyagi   Prefecture (District),  which was   badly  damaged   by  the  powerful  Earthquake  and  tsunami  in 2011,  could  solve   food  shortages   in  the world
Another  such  farm  is  Green  Sense  Farm   an  Indiana  based  vertical   farm,  which  produced  herbs ,leafy  greens and  lettuces using LED  lights.
