Choosing the right seeds for you depends on five factors:
1) What are the desired medicinal and therapeutic effects you're seeking?
2) Are you planning to grow indoors or outdoors?
3) How important is a high yield?
4) How much space do you have?
5) How comfortable are you as a grower?
The answer to each of these questions will narrow down your choice and help you select the seed and strain that is right for you.
