Agreed, try and give your self at least 1.5" squares to deal with. Also I use a hemp yarn to give the screen a little play when I tuk and can always re-tighten the screen by torquing on the unglued PVC with a pair of channel locks...Heres how it looks on my small tent.chicken wire is awful to work with especially outdoors the plants get way to big come time to harvest . you have to cut back a lot of a chicken wire it's better to you something with larger diameter holes like horse fence . Or custom made.
