That makes me think of another way to explain it.
Average plant, average environment, average grower skills = use "best practices". Use the tools according to the instructions.
Of course, not everything is average, darn it.
So we fiddle and change things around a bit, to see if we can deal with the non-average stuff.
Or sometimes, like me, you just see how lazy you can be and still have the critters do their excellence thing. My plants have been magnificently fugly lately, but the buds are amazing - fat, knarly, stinky things, full of foxtails ...
It's very very hard to screw up a DBHBB grow.
