I think the main things for me are:
- smaller pots (may also require an autowater/feed system)
- trimming lowers (widest branches come from the bottom and are furthest from light)
- topping (keep height down and divert bud production to mains)
- short veg (keeps plant small, reduces cycle time)
Using small pots is a pretty necessary step, otherwise, keeping up with the amount of required media becomes a major chore/expense.
