If you use good training, you'll just end up with some bigger yield on some of the bigger ones, while keeping all the vertical growth in check, so there all coming up around the same heights.
Staggaring the flower room allows much higher production over time. I harvest meds every couple of weeks and plug a new veg plant in.
Also less work at a time but its consistant. Only need to harvest/ trim a plant or two at a time. Only need to water/ feed/ transplant/ train a few plants at a time any given day.
Once in a while a whole bunch of plants need care on the same day. Mrs. MMG calls that the “trifecta”. She is not a gambler. Lol. ;-)
