Topped will def reduce the size of your biggest cola. since hight is the issue, it may be your only option. LST may need a little more latteral room. (if u bend a plant over will it be in the way of another plant?

What indica strain are u growing??

if it is a short (even for indica) strain like afgan u may want to just force flower a little earlier when the plant is just under half the hight your grow area can deal with.

the slightly shorter veg time may produce a smaller plant with smaller yeild, but with a main cola larger than a topped plant.

but u get through veg+flower in slightle less time which means u star next grow a couple of weeks sooner.... increasing your yeild over the course of the whole year.


But if i had to choose; Top or train.... train.
