Well judging from the fact that certain strains are known to grow to certain hights.
AK-46 = 45cm-55cm indoor (AK 47 Marijuana Seeds High Quality serious seeds)

but im wondering.. my one pot is large... larger than most indoor pots, i mean it takes 2 people to move it (that's dragging it across the ground), this plant may grow higher. I mean it hasn't even started flowering yet and is higher than 55cm. however the plant in the smaller pot (which is the same age) is a lot smaller.

haha i guess i kinda answered my own question, but anyways :> Thanks for the comment :>
glad to see someone is watching my log
