Assuming that the mother plant was in her PRE-FLOWERING phase ...the clones should be ready.....but u need to look to see for yourself...im sure the buds will all burst through if u start the 12/12 cycle..and u can train them accordingly..the dcision is yours ..maybe wait 2-3 more days....is that a bubbler?? and what size are those pots?? i fancy using the same set-up!!
