How Tall

I need to know how tall a northern light plant willl get, cant find on the internet and need to kno because i have limited space.

it really depends on how big you let them get, eg.. 3 weeks vegging vs 10 weeks vegging. And the plant genetics if it's more indica figure 25 to 50 percent larger than how tall it is when you start flowering. Sativa dominant i would say 200 to 400 percent larger. these of course are just rough estimates. If the plant/s start getting larger than you want you can top or LST them also.
Hope this helps
