Ive got like a 10" may be 12" I took of a plant in bud while lolipopping,I took a lot more but Id like the big one to work,the others have just shrivelled up,im normally guaranteed 8-9/10 clones take (in veg),all the clones that had no bud on them took but most the ones with bud at top folded even with support,leafs just shriveled,would take to long to put back in to veg once budded I recon..
For what OP wants I would suggest taking big cuttings 2 week before going in to flower,in that 2 week they will get roots and strenghen up.Thats what il be doing,problem is youl have to move them in and out the room so they get there 18/6 as your room will be going 112/12 uness you hold out or have a seperat bloom room.
I would like a video of people growing clones with bud on already,does it work?
