Hello
@Growmore !! How are you?
There isn't really a time for veg. Some people start from seed straight with the flowering schedule, so you can get faster yields. Remember that the shorter period you veg your plant, smaller she'll eventually be, it's almost proportional. Also the size of the pot.
Back to your question, in smaller areas it's always preferable to have lower veg periods, otherwise it'll be very hard to manage the space and growth.
Let me know if I can help you with anything else.
cheers
