Strain quality and stability has everything to do with the nuances of whether or not they will throw nanners or pods due to a light leak. If you're strain is stable, you don't even have to worry about leaks. As long as they are fairly insignificant. Period.
I now own my home and never have to worry about landlords or light leaks ever again, however I paid my dues for yeeeears in rentals growing with shitty Amazon tents and makeshift gardens constructed of panda film and 2X4's.
