Hey guys, got a vivosun tent 2x4x5 ft. Got two vivosun 300 watt led lights and also got a carbon filter coming. I put the tent together and it only has one crossbar to attach too. I was wanting to attach the carbon filter at top of tent and have one light covering a 2x2 area. I'm needing help on how i should add another bar Or 2? Or a diy idea. Or does vivosun offer spare parts? Thanks
