A question from a fellow grower:
I wonder if indoor is better for G13 or outdoor? Also is it easy to care?
Either way. G13 is an indica so it would work great as an indoor plant, indicas tend to be shorter and bushier than sativas. That being said, there is no substitute for the real thing, the sun. All strains when well taken care of and grown in the right time of the year outdoors will give you about the best yield you could ask for.
