here again. i posted in your other thread so ill post here too.

from the height of that box id say you are best off doing a pure indica or a few autoflowers. you gotta remember the height of your pot goes into the equation.
so autoflowers recommended ... pure indica or even ...

a nicely done indica x sativa either lst'ed or somehow perfectly scrog'd.

id try and add a foot to the height of the box but if not... i think you have the right ideas so far.

as far as perfect strain or yield i couldn't tell ya.. you have to go buy seed description and application of whatever skills ya have. i'd hate to limit myself to that much head room but I see people do it all the time so here's some luck to ya!
