You could be right on that one mate, i'm seriously considering putting a partition up in the bedroom 2m x 4m at ceiling height which is 2.4m so could in theory get slower but stronger genetics like master kush or girl scout cookies , only thing that's putting me off is the prospect of getting dodgy genetics , some have too many vastly differing phenotypes, for example i brought 4 ww cross bigbud from female seeds each one was pretty bad apart from one so i used her as a motherplant but the clones were significantly less vigorous to the point where my "from seed" girls were ready at the same time as the clones, i was kinda stuck in a savage loop with it and ended up throwing out a dozen clones just to negate the temptation to run them again...changing strains is always a gamble so if you can suggest something top shelf that maybe needs 10/12 weeks after flipping to 12s
