I veg these about 6 weeks under a net scrog, i get em about 3ft in veg depending on strain, they were never more than 3ft high since i kept them under the nets, some get 5/6 ft if they were left to grow upright, scrog is perfect solution for hight issues, also keep your lights as close to canopy as you can, I think I had them about 18-20 away. Also strip EVERYTHING below the canopy, the bottoms had two ft of being able to see allthe way to the other side no leaf, the canopy is about 1 ft thick, nothing but good nugs in that harvest, No Co2 running on that either. This will help you get larger nugs. You already have the nice frosty kind! I bet they smoke as good as they look.
