How long can I grow in Rockwool?

Just to quickly summarize, I have 2 plants currently vegging under my HPS and some seeds that just sprouted under a t12 6500k flouro.

My seedlings are in 2" cubes currently and it is going to be at least 8 weeks before I am able to move these into my hydro systems under my HPS to flower.

Is there a general rule of thumb on how long these can grow if transplanted onto larger grow cubes or slabs?

Any opinions on how I should go about growing these under my fluoro's in this time period would help while my hydro and HPS are occupied.

Check out the pics below, sorry for the HPS lines in the pics.

p.s. I should mention that the 2 under the HPS are feminized and the seedlings are bag seed. Although I have extra hydro buckets, I do not want to waste them on the bag seed until I know for sure its a female. My plan is to grow them out under the fluoro's until they show their sex. I just dont know the best way to grow them or if the extra large grow cubes will suffice.
