Should my lights be on when i first plant my seed?

I've looked and looked and I haven't been able to find an answer. I have 3 seeds planted and they are about 1wk to 2days old soil since first cracking and I have my lights on 12-12 since it's the winter time and I don't want them to get too cold during the night. Is this okay?

this answer is short and sweet YES have it on and you should have it on for 18 hours and off for 6 you have it set on flowering time

well really u shud have the light or else they wont grow man, u did science at school didnt you brother, and it shud be on 18 hours a day, 12/12 would ake the alot more colder than 18 hours :S, this is common sense to be honest mate!!!!!!!!!!!!!!11

obviously it's common sense. that's why the lights are on. I wasn't sure if they needed to be 1-3 inches away or what time cycle they should be on. Or which on/off setup is favorable. Your face isn't making common sense to the thirst worms that dig the brain holes of my mind.

Despite what the others have said, I have, with my own eyes, seen a marijuana plant, from seed, grow to at least 2 inches (last time I saw it, since it wasn't mine) inside of a closet with no lighting. And of course these were transplanted soon after to an area with proper lighting. So I personally believe that they can be grown without lighting for a few days, just turn the lights on when they come out of the ground.

yea but if you have a light its best to put it over the plant.......and you should have asked a proper question if you wnated an accurate answer!!!

You should not have typo's in your sentence if you want me to understand your smug statement.
