Do tons of research. Get you a growing guidebook on Amazon, watch YouTube videos, and this site is a very good resource to have. There’s tons of false info when searching online but following growers up here and asking for advice from fellow growers is always your best bet. At the end of the day it’s all about finding out what style growing, setup, strains, ect. Best fits you and the time/effort you’re willing to put into it…not to mention how much money you’re willing to spend on the hobby lol.
Hope this helps a little and best of luck!
