Hello TheJackyl, and welome to the canna boards,

Two 2x2 tents will be the only way to accomplish what you want to do. As you have realized, if you want to run moms + clones/veg, then that is one tent. And obvious that flowering is a second tent. It would be difficult or impossible to divide one 2x4 tent. You could build a box in the bottom of the 2x4 tent, to keep moms/clones, but it limits your head room to flower.

It would be easier to operate two tents, but keep in mind you need to exhaust vent 2 tents which means 2 fans and 2 odor controll methods. And possibly a fan for an air cooled hood.

Having never faced the dilemma of having only 6 plants total not sure what is best. I would probably go with your idea of 5/5/2. You could then keep two different strains as moms, for some variety...tho I would run the same strain in cuttings/clones to veg and again one strain in flower. That way each run is more consistant with growth pattern and finishing time. Mix them and you may have a half empty tent in flower at times.

Hope this is helpfull to ya. good growing to you.:thumbsup:
