Hey abd , yea you might want to remove some of the lower growth that wont recieve much light , i would just take a bunch of leaf off , more like a trim , " lolipopping" is a much more extreme removal of leaf , stem , and small bud ....
Its a specific way to grow just the main and very top buds , hence the name " lollipop"
Personally , i dont like the technique at all , and never used it , i prefer to let my plants grow in a more natural fasion and using enough light and not overcrowding will produce natural budsites thet produce as much or more end product......
