when do I start the lighting of 12-12?

or how tall dose the plant half to be befor it gose into 12-12?

I an going on a trip for 7 or more days in just a week.

wnat can I do to ceep my plant alive and heathly.

I have a hydroponic system not in use. would thet work if I transplanted the plant to it.

I also have fans and a good timer for the lights. it's lookin good. will this work.

 

Hey DW: 6wks veg, regardless of size: if you let 'm grow up they could be 3or 4ft tall, if you'd tied'm down they might not exceed 2ft. 6wks then cut the time! Unless you have lots of room, tall room that is, and then you gotta think about how well you can get light to all potential bud sites, and that's where you're then goin' to want to put up more light to feed that light to all those sites below the main cola. You know what I mean>> plan your strategy in advance and go with that plan: low growing plants>>6 wks., tall growing plants>>as much room and extra light as you've got. LOL b1
Oh, and for your 7 days: do nothing as long as you've got lights on a timer, water 'm before you leave. If more then 7 days, involve your friends as caretaker is what I would do.b1

 

You can also use low stress training, basically tieing the plants over so they are growing more horizontally than vertically, which distributes growth hormones throughout the plant, enhancing bud sites below the main kola.

 

if the day length and temp are decreased the plants will need less water since metabolism will also decrease but you still need good air circulation.
