lighting for flowering

do the lights have to stay at 12/12 for flowering? or once they are sexed and flowering can you just let the light go???? please help

12/12 all the way and make sure dark time is dark dont wanna stress em and they grow balls

2 k lights all hps do i need any mh for potency or beef?

12/12 whole way hps

HPS 12/12 all the way. No interrupting the sleeping plants with light or you are fucked. Green lightbulbs dont interrupt sleeping plants so you can work in the garden at night if you have to.

If you got both, use both...your plants will love it!!!
