Forget about the AK-48....Buy and grow AK-47 much much better smoke and finishes in 53-60 days. 18/6 veg, 12/12 flower
You said you wanted to grow AK-48, not that you already had it so let's not get pissy with one of our better members as you did here. To answer your question, you'll probably get a better yield if you veg for one month at 18/6 then switch to 12/12 until harvest. Nothing wrong with 12/12 from seed, just not my thing. According to the strain info I found via google(something you could have easily done yourself), it will take 7-8 weeks to flower.well I have 20--AK-48 so answer the question please, not give an opinion....
