If you want an even canopy you have to press the screen down nicely into the plant..make sure no branches are coming through the holes , then fold and bend them and keep them down under the screen, make sure nothing is poking out of the screen...I see lots of people doing it wrong, ..thatvwill keep your canopy even, then after your flip and another screen on top about 6inces apart that will be the screen they use for support
