Choose your strains based on your climate.
Do some research into mold resistance, cold hardiness, finishing time at certain latitudes, etc.
The higher latitude you live in, the more important it is that you choose a fast strain.
Lower, equitorial or subtropical latitudes can take longer.
Humid areas require mold resistance such as a fluffy Sativa style bud that dries quickly after rain
Etc....


So where do you live?
Region?
Mountains, coastal, desert???
What's your summer weather typically like?
