The end of my PVC joints are open, so I just screwed in some screws to the wall so they went inside the PVC, then tied the pvc to the hooks I use to hang the light for extra support. The screen helped me out alot with the PK because it was mature when I put it into flower. Next go around I'm going to have a full fat screen of buds. I figure I should have the system dialed in after this. Don't you hate waking up in the morning with no bud to smoke and you just look at your garden and go.....fuckkkkkk please grow. haha
