I use the same set up as well. When you use adapters to convert for a 4" fan and filter, you add more than 10" for each one. That makes for a light unit just over 4 ft long. Way big and bulky for me! I felt it was a must to use a smaller cfm(210) fan because the 6" is WAAAY too much for a cabinet so a McGyver session was in order. I used some EPMD rubber seal from Lowes and a set of tool box latches to attatch the filter to the tube. The fan is alot more challenging because there are no flat surfaces for the latches so I just put the gasket on the fan, put a hose clamp on the tube to attatch S hooks to and used a stout wire to cinch the fan to the S hooks. This works well for now until I finish this run and come up with a feasable solution. I leave the whole unit mounted almost to the ceiling and just stack buckets on other buckets to bring plants to the light. This also makes for easy inspection of plant undersides and any other accessability issues. The pics are not the best but...
cannakeeper Reviewed by cannakeeper on . HID Lighting (Cool Tube) - A quick question Alright, I'd love to move from CFL to HID lighting. The only problem that's holding me back is the heat. I know HID lights put off some mad heat, but that's just from reading. I'm looking for someone with experience to give me some guidance. I've looked at some 400W MH/HPS (Switchable) Cool Tube setups, but they all have 6" fan hookups. Could I get away with a 6" to 4" adapter running to my 4" exaust fan? Or is the heat too much for my fan to move? (a pretty high CFM fan, sorry I can't Rating: 5
