Please need suggestions/advice

A friend is doing a small grow with 3 seeds he found in a good bag. Has very little room to work with so need to lst the hell out of these plants to get any sort yield. There is another small place that could be used to keep a mother plant and veg a few clones. What would be the best way to handle the 3 vegging plants now? Can you lst a plant in a circle around the pot and still use it as a mother? I've been looking for threads on clonning but it says to take clones from vegging plants.Do You have to change lights and hours to get them to show sex and then put them back into veg? I'm quite confused on how long to veg and lst before flowering. He is hoping to have 2 females so He can mother one and flower and harvest the other if only 1 female then not sure what to do. Please help I am confused and need advice
to come up with plan



Thanks

The reason you keep a mother is because you already know she's female, and that her clones will also be all females.
That's the object . . . one mom, and an endless amount of cloned, already sexed, replicas.

So you'd have to sex your plant(s) then take clones from the females and put those clones back into veg cycle. You could also put the already vegging plants back to veg cycle if you want. Males usually show first.

I let a girl flower, then re-veg that plant if it is perfect (no hermies, decent harvest) to ensure that I'm not cloning hermies or low producers.
Then that re-veg becomes the mom.
