For a beginner you can't fail with soil, unless you overwater or absoloutely slaughter them with nutes.
Hydro' is fairly easy too. You can hand water in hydro too, you don't need all the fancy equipment. i grew hydro in rockwool and perlite and hand-watered.
In soil, your first time, you'll probably max out an ounce per plant.
It's best to go through the levels, and soil is level one. At least this is how I look at it. Soil is level one, hydro level 2, dwc level 3, aero level 4. I've missed out nft, as it's not a method I like the look of. The levels I speak of seem to naturally follow one another, and this is the route I am taking. At the moment I've just started my first dwc crop.
