Yes topping for sure. But there lower branches grow in uniform with the top. Normally when I top I have to eventually cut a lot of the bottom stuff off because there tops don’t reach far enough up the plant. Whatever training technique there using I believe is a big factor in creating allot of tops without having to Lst. I grow 70 plants and I wouldn’t dare try Lst that many plants. I’m trying to pick the growers brain but I’m just another follower asking him a bunch of questions.
