Create a frame that involves 4 upright pvc tubes. Drill them with holes every 2-6 inches so you can twist-tie a screen into place.
Get a 4' x 7' sheet of concrete screen from home depot. Bend two 1 1/2' wings so the screen has a footprint of 4' x 4'. Secure screen to pvc with wire ties. Between the two wings you can twist tie some horticultural trellis from 6-18" up from the wire frame. So the colas when they fall due to weight they will be contained by the horti trellis.
I have found that 1/2" eletrical conduit actually works better than PVC. Its smaller and much more rigid. I simply hung mine from the ceiling with left over wiring. easily adjustable, no legs to hit and you can tie it up out of the way if needed.
my tent is 8'x4' so what i did was get some straight pvc fittings (1/2") and drilled 1 hole for a bolt and then opened up the tent poles and slide it over in the 4 corners and slid a T fitting over also on the top and after reconntecting the tent poles the fitting slid up/down on the pole and the bolt would clamp them in place, then i had some scrap pvc ~6" on each T to support the 4 corners of the screen. it made adjusting that big ass thing easy cause i could do a corner at a time easily.
