Actually if you do have a dark period is what happens is the Kannabis plants uses up the stored energy it produces when the lights are on. 24/7 will allow them to continually produce energy for root and leaf development. Some say the roots only grow when the light is off. Not true, the roots grow in direct proportion to the leaf mass, more leaf mass needs more root mass to continue to grow new leaf mass.

Good Kannabis Growing!
