When do the lights come on?

Do you turn the lights on as soon as the germinated seed is in soil or do you wait until it pokes out and then turn the lights on?

it doesnt really matter but i personally leave them on so that as soon as it does pop out it will start getting light right away.

I start my lights on a timer as soon as they as they have a root out and are in their permanent growing space. It's not a necessity for them by any means, but might as well keep their environment as regulated as possible when dealing with anything that has a circadian rhythm. Who knows if the warm/cold cycle from radiant heat at the surface plays a role in anything as far as development? If you want to save a couple of dollars - no strict need to give seedlings light until the cotyledons start to open. No worries.

It also gives newer growers some test run of the timers / equipment etc.....

Thanks guys! I'm kind of an experienced grower, but this particular question I did not have a 100% answer to, although I personally have the light on from the get go. +reps for everyone!!
