Outdoors and Lighting Requirements

  1. So indoors, you need 18 hours for veg and 12 hours for flowering... Where is this magical cutoff point where the plant knows the difference? Today June 21st is the longest day of the year, and it is 15.5 hours of light in my region... Does that mean that technically you can grow indoors at veg with only 15.5 hours of light too?
     
  2. I've grown indoor with as little as 14 light isn't the only factor that determines flowering.
