I can't answer your questions but I'm also curious about keeping a sour diesel mother plant. Mine is 1month 3 weeks and is like 10 1/2" but fuckin bushy as hell . What about yours?

3 or 4 feet tall from july 4th under a 4 bulb 4foot t5 sunleaves fixture till bout a week ago i got a 1000 watt hps/mh setup

Were / are they really bushy? I figured sour diesel was a sativa dominant strain and would be taller rather than bushier. But mine are surprising me being 11 1/2" tall and almost 10" wide! All under a 400w mh and 4 4' t8 flos cool white/ daylight mixed bulbs

yea there probably as wide as they are tall but i also trained them by bending the tops and lst'n
