approx, it can be however long you want man...veg for a month and flower for 1.5 months,,,,or veg for 2.5 and flower for 2...average is around 85days though..look on google under ak48 and itll give you a description of plant with estimated flower or harvest time, cant remember which one they give ya..
It can be as short as 7 weeks if conditions are optimal. Otherwise, on average 8 weeks. Or use your 'rule of thumb' to determine the best time to harvest. I currently in my 6th week flower with ak-48 and only one of 6 looks ready. Now I got 5. You do the math!
hmmm dont guess i ever smoked n-e a-k strain ....i smoke some afgani before ... really potent stuff good thou. good luck with ur grow bro
