420420, I want to ask you : in which exact week you changed the system from 18/6 to 12/12?And when on 12/12,I am I obligated to keep the room totally dark or it's acceptable the lights in the room to be like a room with dark curtains on the windows,I mean a little brighter than a full dark room,cause the room have windows alongside one of the walls ,almost the whole wall.I have a couple of plants which I've started to grow just for fun,back in time I have grown plants outdoor in a country with very hot and sunny weather.I keep growing them for fun but I would like to give them at least half of the good care I can give them without setting up the expensive systems for perfect growing.I know from experience that the weed is very very resilient and it can be grown in very rough conditions but aperantly the sun in UK is not sufficient enough and I am replacing it with the cheaper CFLights.Please tell me abot the systems 18/6 and 12/12 and answer on my question on the lights,I know It's your first grow but I also can see that you manage very well.Cheers,I am waiting also for the pictures update.
