I appreciate all of the advice everyone has given me... This was my first outdoor grow, and they're in the ground not a pot. They're big though the largest being at about 12 feet. I checked them yesterday and still looking amazing!!!
You don't need to do 2 breathes, if you're a champ you can do it in 1. I really like around 19inches... Not because it gets me higher or what not, but just because that's what feels right to me
