We were discussing modifications to a tent to provide a method of hanging side lighting. How about this?
While ( before ) you are erecting your tent:
Measure the diameter of your horizontal support poles.
Go to your local Home Improvement store and buy some PVC tees that will slide completely over your poles.
Purchase enough to put a couple on every horizontal tube (top, middle, etc.), or anywhere you might want an additional rod.
Purchase enough PVC pipe, that fits snugly into the tees, to cut into the width of your tent.
You can position the tees where you want to hang anything from side lights to SOG screens to yoyos, then push the PVC into the opposing tees. This can be done after the tent is assembled and can be done at any time during the grow. As long as your PVC pipe is cut correctly, this will support anything you wish to hang.
Loop a chain over the support rod and connect your rope hanger to the two ends. Now this chain can be slid along the rod easily by lifting the end of your light and sliding the chain with a broomstick to adjust the distance from the grow.
If you are using the lower side ones for SCROG, they can be removed when not in use and the tees will just hang on the cross pieces.
As for the light fixtures. Every hanging light fixture is hung from four points. I prefer chains over brackets, here's why.
A chain with an odd number of links has a specific center which will not change when the fixture is tilted. I would put a chain at either end of the fixture and attach the rope hanger to the center link.
I would also run a chain lengthwise on one side of the fixture. I would attach one end of a third rope hanger to the center link of that chain and the other end to a chain hanging from a support rod (also adjustable with a broomstick). As you tighten this rope hanger the fixture will tilt. It will now be completely adjustable in height, distance, and tilt.
I hope this makes sense. Let me know if you have questions.
