Krissy u cannot tell the strain from looking @ it but its healthy lol
a plant will grow forever seemingly as long as it has more then 12 hrs of light. so if say
ur giving it 18 hrs of light and 6 hrs off. it will grow until u change that schedule to 12hrs on 12 hrs off.
i wouldnt do this until about 5-6 weeks in.
however with the question u posted im thinking u have this under like a desk lamp or single CFL house bulb.
this will not produce buds. ull need 125w from grow store. and the plant could still turn out to be male and useless.
the previous guy who stated ur lazy and demonstrated frustration is because ur question is of the most basic
nature possible and could be easily googled. i however ask questions i could google sometimes to get a human response
so i figured id provide one to ya. Happy growin.
Keep it green.
