Going 12/12 while rooting sativa cuttings for a SOG?

So I just started flowering a Dinafem Super Silver plant in a ScrOG setup, but I'm planning to convert this grow space into a perpetual SOG once the ScrOG is done. Assuming I'm happy with this plant, I'd like to keep a clone/mother box and use that to supply fresh clones for the SOG every week or so.

Here's the clone/mother box I made:



As you can see, it's a pretty small box. I'm planning to use a soil container that fits the entire bottom of the box snugly, and then have it only be a couple inches deep (bonsai-style, which is another of my hobbies). That will limit the vertical height I lose to the soil and container. However, using that setup, I would not really have room to veg (or even root) the cuttings in the box, so I'm considering just putting them directly into the flowering box. But I've never heard of rooting cuttings under 12/12 before.

So here's my question: Is it possible to root cuttings under 12/12? This is a sativa strain that flowers for 90-100+ days, and the plant I have so far is exhibiting rapid and vigorous growth. Here's a photo of the plant today day 28 from seed, and this is despite a FIM at the 3rd node (which slowed things down), and the removal of two branches to be cuttings:



But the problem is I don't know if being under 12/12 stops root formation (obviously something that would kill a cutting that isn't rooted yet), or if there is some other major problem associated with trying to root under 12/12.

I realize this will not produce as high yields as it would if I root them or veg them a bit first, but high yields aren't my goal here. I just want to make sure they will root and then continue to grow enough that they will produce some reasonable amount of bud for such a small plant. So.... will they?? Thanks!

as far as scientifically I couldn't tell ya. But right now I have 8 cloning in my flower room only because my new veg spot is literally 2 inches to short width side to fit my tray. Horrible. So far so good. I have 2 haze clOnes myself and their doing just fine. 7 days and roots coming through, rockwool cubes then into Ffof blend. Hope this helps

Scientifically schmientifically, nothing beats actual experience! I figured this is the kind of thing people have done before, I just was curious whether it generally produces good or bad results. Good to hear that at least the rooting part works out. Are you planning to then move the clones into a veg chamber, though? I would be leaving them under 12/12, basically starting their flowering regime the moment the cutting is dipped in rooting solution and popped in the rooting medium.

So then, experience has shown the feasibility of root primordia formation on a 12-12 cycle? Thanks RIU geniuses.

I probably should have updated this thread, since I actually rooted a couple plants under 12/12. For one clone, I accidentally broke a branch off while I was training the plant in a ScrOG setup around day 20-25 of 12/12. I decided to try to root it even though it already had flowers showing. The plant became a pretty amazing little specimen that would have been PERFECT for a micro-cab grow, since it had no veg and no stretch. The plant pictured below was grown entirely under a single CFL for its entire life from rooting to harvest. For almost the entire period, that was a 26w CFL, but for the last couple weeks it was a 42w CFL. Pretty dense little cola for a single CFL, right?

looks like you pulled it off good looking nug you got there now imagine about twenty or thirty of those haha
