height

shortest in hight autoflower for back garden (little smell)
cheers fil

Like I say everytime someone asks this.... LST it and you can use whatever strain you want AND get a lot more bud than if you let it grow untrained.... much more light to the budsites. youd be surprised how muchj light intensity drops off every couple inches. keeping a flat canopy is really a big help

i've grown several northern light autos. i generally keep them at about 23" tall. very low odor, excellent yields and really good smoke. as mentioned, there are many methods of growing to help keep them shorter. GL
