52 day veg to flower

has anyone heard of using 18hr days to achieve fsater growth?
veg 12 on 6 off 7days. flower 6 on 12 off 45 days.
using hydro with high heat and co2.

no, that is news to me. kinda wierd too.

I heard of it being mentioned, but no evidence to support it. I would personally opinionate that for thousands, if not millions of years the plant has been used to a 24hr cycle, and that to change that cycle would take another couple thousand genetic cycles for the plant to become used to the change.
