light cycle

[dirtyman]

hey guys iv decided to change light cycle and tonight i was planning on turning the lights off for 24 hours and then to 12/12 what i wanted to no is is should i flush before i turn the light off and if so shood i leave just the clean pure water in the bubble ponic system for the twenty four hours or shood i just do a quick flush and change to bloom nutrients and leave that in the system in the dark for 24 hours?? i no that sounds a bit fryed but its me first time and i wanna do it rite thanx!

 

heres a picture of the system its in just a 20 ltr tub with air stone and pump

just a quick flush and add the bloom and off ya trot ,oh and why waste 12 hours of growing ?
