clones and light

just got some clones from the dispensary and put them in my ebb and flow table. i was planning on doing a modified SoG grow and start to flower them immediately. they are already rooted in rockwool. should i start out with the 12 hours of light for flowering, or go with 18 hours of light for clones/cuttings? since they are already rooted i figured i could just go with 12 hours of light (600W HPS by the way). any thoughts?

I would go 18/6 for at least a week or two and then flip them to 12/12. Just depends how big you want them my friend. Give them one or two weeks to pack on some more nodes so you get more bud.
