what size holes in the "mesh" do you plan on? a rigid screen works but i don't know about just throwing a mesh "net" over the plant. 1 other thing, if you fill it completely in veg it will outgrow it within the 1st 2weeks of flower. you have to leave some room for stretch. it's a good idea, i just don't think it's feasible. you would need to be able to get to both sides of the mesh for training and also this method won't create the nice even canopy that traditional scrog does. i could be wrong about this as i have never heard of anything like it before. i am just going by my knowledge of how mj grows from growing many plants over time. let's hear some other opinions.
