...because I have always had good results with topping, fimming didn't work for me this time, I don't know what LST is, and tying plants down seems even more unnatural and stressful to me for plants.
In nature, bugs and birds chomp on leaves, especially while young and tender seedlings, as they did on one of my plants here, and topping may mimic this somewhat.
I like the way plants look when topped and bushy with many "main" branches, and reading that others here also don't experience negative stress when topping, I think I will stick to this. I also notice growth really takes off when topping, and when left alone it seems like the vertical growth and growth of the bottom branches from nodes on the main stem take FOREVER!
Topping...works for me!
