Bad to prune a sativa that wants to grow tall???

so say theres limited vertical space and someone wanted to grow sativas that are known for being taller. could you prune and keep them shorter without negativley affecting the yield/quality outcome too greatly???
In an indoor enviroment obviously with good light source.

just supercrop it

but generally any pruning is stressful, sativas are just less accepting of it

lst for sativas is good imo, you can top them too if they're young and vegging. If you let it start blooming and its getting too tall though, you may be SOL, that main cola stem can stretch up far.

ive decided to bend with string, grow horizontal

thats the best way to grow horizontal ,will get bigger yield due to even light on canopy

hey obbz,yeah horizontal you will get great results,thats how i grow to the space i have got rather than filling it with straight up and down plants check out my photo album if you need any pointers
