indoors is really alot better for me that is. Everyone is different. i like to grow indoors because you can control when you want your plant to begin the veg stage by changing the light time to 12 hrs a day. Also it grows alot faster indoors than out. there is also less problems with law enforcement seeing it.
i have also grown outdoors but got caught by helicopters and another time by neibors ratting mme out. There is also alot more problems with humidity, temp., and pest.
