That's what I have the most experience with. Coco is considered hydroponics though, meaning their are no nutrients in the coco likenyou find in soil so you have to add them for the entire cycle. I wouldn't recommend Hydro for outdoor gardening though, soil is best. If you are gonna start growing Hydro for the first time, I would suggest using emerald harvest nutrients. They have a super simple 3 part regiment that puts out super sticky nugs without a bunch of other shit. I recently recommended it to a friend and he harvested some beautiful, tasty flower his first try. Go to your local hydro shop and Ask them some questions they can help. If you are gonna go with soil again, I would suggest using fox farm, roots organic, or happy frog over miracle grow. You can get it at the hydro shop and it doesn't cost that much more and it's better quality. Their are also some pre mixed super soils like the Michigan Made brand. Its expensive but you don't need nutrients at all, just clean water from seed to flower and you don't have to buy all the amendments and mix the soil yourself. There are so many options, it just depends on your situation, budget, and how much time you have to spend on the garden.
