Indoor Timers, new grower

[xasiklas]

Hi guys, at what point in I add the timer for my lights?
At the moment they are 6 days old seedlings on 2x400watt MH lamps.
I can provide with more information if needed.

I just failed to post it to the correct subsection. if any moderator is kind enough to move it, pls do thanks

Personally I always have them on the timer even if they run 24 hours on as my timer and most timers have a fuse and give me a sense of protection

Sounds a bit overboard, for 6 seedlings. A lot of photo growers use T5's till flower. I am out of touch with the needs of AF's, these days.
