Different Strains

Is it a smart idea to grow different strains at the same time in the same unit? I just have a single 10 pot unit that I use from start to finish. I just received 4 strains and would like to grow 2 of each strain if I can. It would seem that all of them have flowering times of 8 to 9 weeks which seems pretty standard to me. For a personal grow setup wouldn't it be smarter to grow all 4 at once then 1 at a time even though there might be a slightly reduced yield from 1 or 2 of the strains?

Shouldnt be a problem. If one strain or plant needs to be harvested sooner or later than others it can simply be cut without problems while the others continue to grow. Be more specific about your growing setup. The only thing I can think of is the different strains needing different PPMs of nutes. But that isnt a big deal.
