All depends how much room youve got mate, if topped then it will need a bit longer to veg just to recover in my opinion. Im doing some blue cheese at the min and doing about 5-6 weeks veg then going to switch to 12/12, just lets the plant mature abit before flowering. You gotta think though, the plant can double or triple in size when put in to flower, not sure if this answers your question though. Lol
