Never had northern lights but seem to be quite popular, hope all goes well. What type of light are you going to use for blooming ?

I have a wardrobe fitted out with a 250w HPS and carbon filter and plenty of ventilation, i have lined the room with white painted floor and walls and i think i`ll have room for 2 or 3 girls, mine are mexican sative and i understand they can get up to 2-3 meters so i`m going to bloom them after a couple of weeks of vegging and LST them to keep the height down and may even add some warm CFL`s to the aid the mid and lower branches, can`t wait.

Yes this is my first grow
