well a multi-billion dollar horticulture industry all ready does it and has done it year on year every year on trees and vines for over 12 years on the same plants /vines 2-3 times a season , yes it sounds crazy doesn't it. ring barking them, it makes more sense in cannabis which is basically a annual than say a grape vine or kiwifruit vine which will suffer 50 girdles plus in its life span, the industry has been forced to do this to meet the market,if you dont girdle you go broke competing with those who do. with cannabis it makes more sense as the plant is short lived. its basically starving carbohydrates temporary to the roots, to boost gains in fruit, or in our case buds.
Girding, doesn't kill if done correctly, you must do the girdle width and depth according to the plant so it bridges the ring bark are with cambium within 4-10 days.
