hi co de,
the height of white rhino grown indoors should be approx 4'.
anywhere near 6' and i'm fucked.
i'm 2 weeks into my first grow (in a wardrobe) and picked wr because of its lowish height, and the lure of medicinal strength bud.
if all goes well i plan to start flowering when it gets to between 12''-18'', hopefully this will keep the height down a bit.
good luck!
