Can anyone suggest me a strain ??

i need something with a decent strength that is moderately easy to grow but most of all can be grown in a 3ft tall box.

Any ideas i was looking at Hawaiian snow but its pretty damn tall, up to 6ft i hear

if you want to try a training technique like LST, then you should be able to work within 3 feet
in my case with a similar height, i went with an indica, northern lights, and it came through for me on my 1st grow, finished at 29 inches
much depends, of course, on what you prefer for smoke, sativa or indica

Check the white russian, strong strain, short bushy and good yeilds

White Rhino
