which is the best carbon filter 2 go with. 1 fitted into the ceiling filled with carbon granules or 1 made with carbon matting and suspended above the plants.
They both fit on the out venting. its just that 1 is suspended directly above the plants and made of carbon matting. And the other fits in the ceiling and is filled with carbon granules. but which is going to be the best 1. The matting filter will get the odour straight off the top of the plant and the other has 2 rely on the odour reaching the extractor fan b4 being extracted.
I have never heard of what you are trying to describe but the best ones to go with are the can carbon filters they hang or can be mounted how ever you need for your set up and are able to have air pulled or pushed through them to clean it IMO they work best if you put them inside over the plants and have the dirty air pulled-in the filter and exhausted out of the room or tent Sent from iPhone 5
the carbon filter im on about is a homemade 1 that is fitted into the ceiling. its basicly a vent with a peice of tube fitted and then filled with carbon granules and the an extractor fan fitted to pull the air through the carbon. But im just trying 2 see which is best 2 use.
