I am sorry, well 48 to 72 hours should do you. Some strains really start to pack on the christels during that period wile some don't seem to show a visual difference. There is a process with the chlorophyll and so onn that kicks in during this time and manufactures the last bits of the goody stuff to make it simple. Remember when lights are out the plant is kind of working double time, that is a whole other lesson though.
Well thanks you darling damsel without stress.
