I know 12/12 to get them to flower but what about after they've flowered can you set the light back on 24/7 or do you gotta keep it 12/12 throughout the flowering cycle?
Switching the light schedule from 12/12 back to 24/7 or 18/6 will actually cause the plant(s) to return to the vegetative stage of growth not to mention it could cause undo stress to them.
