Efficient Rotating Harvest?

Looking for some opinions on how to set up an efficient rotating harvest between two equal size rooms. Is it best to keep a mother in veg or can it be timed to take clones from the other veg room?

Bear with me here. I estimated about 3-4 weeks to veg, 8-9 for flower and 2 weeks to root clones before veg.

Cuttings are taken in week 3 of 4 in veg from Room 1, rooted for 2 weeks and placed in veg in Room 2. By this logic, my friend will be taking a second set of cuttings from Room 2 (to repopulate Room 1) at approximately 8 weeks (3 for cuttings, 2 to root, 3 more for more cuttings). Those should be ready for veg by week 10. Unfortunately, Room 1 is in flower until approximately week 12 and Room 2 would be just going into flower. What to do with these rooted clones for 2-3 weeks while he waits for Room 1 to free up.

It seems this is all solved by keeping mothers in veg and taking clones as needed and not because he needs to flower that room in a week...but, that requires another room. If for some reason he has to keep them, approx. how many cuttings can you expect from one mother? (for a space estimate)

you really need a seperate room to keep mother plants so you can take cuttings anytime you wish and ideally the same room could also be used to root clones and to veg them for 3-4 weeks so the 2 rooms are always flowering and are not used to veg at all.
you can get alot of cuttings from a mother plant by the time the mother plant is a few months old it should supply you with more cuttings than what will ever be needed that being said would probably allow for space to have a few mother plants as you will probably eventually want more than one strain.

I think he was hoping to use both rooms as dual veg/flower because this may be done in dwc/nft and it might be a pain to move them to a flower room once finished in the mother/veg/clone room.

ETA: The timing problem is solved by keeping a few mothers in veg and taking clones as needed (not on the schedule of that latest veg room). Just seeing if anyone had a method for rotating without mothers as the clones can be done in the limited leftover space, but cramming moms in there would be pushing it.

Take your cuttings a little later... only getting past the first delay seems to be the issue. Lets assume 12 weeks in flower room 1 is veg room 2 is bloom

2 weeks before the first set from room 1 goes into room 2, take clones. This gives your soon-to-be-flowering plants 2 weeks to "heal" and grow normal again before putting them in the bloomroom

Now you have clones - rooted in 2 weeks - veg for another 6 or 7, then take clones again. The clones can stay in the veg room/light schedule no problem, the plants going into flower have plenty of time to heal - repeat. The only bad is it might start getting crowded in there around week 10-12 (8 weeks of veg on a clone is a lot!), and since you are vegging the donor plants, you will likely be giving them a high N fertilizer, which can increase the time for clones to root

if you timed it right you could probably keep a few mothers in soil and simply move them back and forth between the two rooms assuming there would only be one room in flowering at a time but you would probably be looking at extending your veg time to around 6 weeks to give you time to root clones and veg them while the other room is finishing flowering.
