Well, lets see. It is fascinating to walk out of my shed where my girls are tight under LED's or whatever light. Two fans at least, either an air conditioner or heater blowing. All the nutes, the timers, etc.
Then I walk outside and see huge happy girls blowing in a natural breeze, not any heating or air conditioning. No bug problems because there are beneficials in the yard that take care of any bugs. They are grown the way nature intended... AND mother nature tells when they are ready. No days to count.
We really have amazing info on how to do an indoor grow and get a decent product and quantity. We are lucky we can do that.
I don't think i have explained this well at all. THe whole environment is different no matter how we try to mimic the outdoors, we really can't, or at least I can't. Wish I could explain it better, you just have to do both to see the difference in growth.
Folks can argue that indoor is more potent and out door is harder to harvest which may be true.. I hope I helped your curiosity a tiny bit. Green mojo to your grow.
