I feel like defoliation is like flushing, some people do it some people don’t and it’s a hot debate. Check out my Frostette (Grape Crème Cake x Okie journal. I tested pretty heavy on defoliation in that grow, and it was one of my best.
All I can say is, you only have to have one seeded tent to think twice about prevention! If it’s overshadowed with no chance of seeing light, it’s going bye bye. With 4 plants in a 3x3 I’ve gotten it to a height where anything below first net is going bye bye. At that point, any large fan leaves in the middle of the two will get removed, but I’m not removing the bud site particularly so it will start produce buds and reduce larf. Just my process, but everyone has their own :)
