If you have taken a cut or sets of cuts from mothers that haven't been sexed yet you can flip them to 12/12...let them veg a few days to take root and not stress is preferred before the flip.
you can skip the rockwool and just put them in a cup of water. label them all and put them in a cup of water and they will sex and root both. rooting takes forever this way but if you dont really need the cut and just need to sex a $6 cfl and a closet or a box can be your friend if you dont have a dedicated flower room.
Heres why,Ive done this before but not with a scrogg.The root mass strecthes just as much as the plant,wich makes it a bitch to separate .I'm hoping some one has done what i want to do with sucess or failure.
I dont really want to seed out the whole room but if neccasary i will do to save these genetics
In the vertical forum there would be many that could answer!
And or search"sea of green" as they flip their clone/cuttings fast. Micro growers do to as they must keep their plants short.
You will find your answer and check up on some really cool grows at the same
You have a good answer from str8dank....caught it after this post!
it will take a fresh cutting a couple weeks to root, a few weeks to get established and a couple weeks to flower. Faster ways, like putting a brown paper bag on a branch 12 hours a day. I have done that and it worked. No hermis or anything but anything is possible.
Thanks Bud i have searched ,thats why i posted here .I haven't checcked mciro grows considering i run 12 plants under 1600 watts plus .Just looking for has it been done and will it work.

I've read the same thing but i have put a paper grcery bag over my head when lites are on and its B/S .the lites i run go right through the bag
Just buy a loop. With magnification and a bit of knowledge you ought to be able to sex most (vast majority) cannabis plants in veg before you can really take a decent cut - before they are a month old.
These popped first week of March and I could sex 2/3 by 3-23. I'm still waiting on one. I typically see definitive pre-flowers between 3 weeks and one month from sprout.
Male below
Female below
Pine
Edit: If I were just looking at the nodes with my naked eye I would be able to see preflower formations, but I would be able to make out enough of the detail to tell male or female; you need a loop or some sort of decent magnification.
if your in 12/12 it will take less then 4 weeks to sex. If your in veg it can take up to 6 weeks to see pre flowers. Some strains will take forever like pure Sativas/Hazes these can go past 8 weeks.
Your answer to designers post! lol
You were definitely on the ball trying the paper bag on your head.... Most people would have just put any old paper bag on their plant.
Designer may have used a thicker paper bag and was able to succeed in a branch flowering. I may try designers technique as I will be growing trees,starting from seed
