High all Am looking at making a carbon filter sort off to add to my extraction fans inside a small grow cupboard. 850x550x1750 of the top of my off head. It consists of 2 x 120mm 240v fans running through 2 seperate lines of 125mm flexi vent into a 100mm two into one(y curved shape) pvc pipe and out the top right hand side. My ? is ,would it be effective to mount the filter directly on the back of the fan with the air pushing through the filter or would it be best to mount it further down the line where the air flow is not that great and the air drifts through.

Merry Chrissy first off, hope you all have a great holiday! now to the questions... Im going to make or get myself a Carbon filter over the next month or so, but i would like to get the fan and ducting now for temp reasons, but I would like to know if i can get away with a in line fan (300L a sec) on a 300mm duct going through a carbon filter or am I going to have to go centrifugal??? im trying to keep this as cheap as possible as usual Cheers

Does anyone know of an australian distributer for electronic ballasts. They say they chew a little less power but increase the lumen output. If i order international, the 240 volt version, it surely would need the wall socket changed. Will i run into any problems there? The rest of the unit complete should be fine i hope Anyone with experience in this Cheers

Thanks to everyone who helped me out with all of the cool tube info. I suppose I forgot the most important question: Is there a loss of light causing a noticable loss of yield when using the cool tubes. I do plan to take out that crappy piece of reflective foil they put in side the tube, and then mount my batwing over the cool tube. Really appreciate any comments. aussie1

I have read a few old threads about members trying to find cool tubes for HID. I know that they are now freely available, but was wondering what sort of temperature drops you guys were experiencing now that you have used them for a while. I was quoted $130 for the 150mm diameter for a 600 watt, and I have to purchase the ducting and the fan on top of that. Any info much appreciated. Regards aussie1
