-Can you keep your clones on 24 hour lights (60 watts led) ? -and when you keep your lights on 24h do they get some rest after that 24 hours ?
I agree with Oz. The only other consideration is the daily light integral. Take the DLI from 24 hours and given PPFD and apply it to a 12 hour light cycle. Half the light should be at least twice the wattage in flower.
I have read you can keep clones under 24 for couple of weeks-
when plant roots and starts to grow, most research shows plants will benefit from a period of darkness.
CAN you grow w/ a 24 hr. cycle? Yes.
but the research supports a darkness period begats healthier, more responsive expressions from the cultivar-
