it depends on the factors of the outdoor grow.

For example; my buddy is growing outdoors but with 50 degree weather, his plants are barely a foot tall and mine are almost done harvesting in 3 months time! (mine are indoor)
Revanche21 Reviewed by Revanche21 on . Outdoor vs Indoor growth I know there is a crap ton of debate of over which is superior, but i was just curious about one aspect. Do outdoor plants generally grow a lot faster than indoor plants or no?? I don't really even have a good comparison, as my indoor set-up was quite sub-par, but i had really slow growth, but as soon as i moved everything outside, they exploded.
