they may have a little transplant shock when doing it during 12/12 but it shouldnt affect them much, but it is probably ideal to do your last transplant before switching to 12/12.
not sure if you put them in 12/12 to sex and then switched back to a veg cyle, will often slow them down for weeks as they revert back to a veg state.
most plants will show their sex usually when they are 4-7 weeks old so you do not have to put them into 12/12 to sex them.
bejay Reviewed by bejay on . When to change buckets Hi, i'm trying soil after hydro and i'm asking myself a question : I germ the seeds in little containers. After 2 weeks, i change for bigger buckets but not the definitive ones. I put the plants under 12/12 to sex them, discard the males, and put the females in the definitive buckets till the end. Is it good, or not? Are there optimal moments to change for bigger buckets, not just after/before setting to 12/12 to avoid root stress in this particular moment, something like that, or is Rating: 5
