Just to get back on topic i am growing 2 white widow plants.Its a very basic set up.A cupboard with 3x20watt CFLs(100watt equiv)

At the moment they are 6 days old.I have them on a 18/6 light cycle..Could i switch over to a 24hour light cycle? and would it do any damage.

I will flower using 2x20watt CFls and 2x125watt envirolites.
