The design relies on a carbon cooker hood filter to deal with the odour but also to replace a light baffle. Conserving space is the biggest design challenge in this situation. Smells are also a complete no no. I have just taken a bit of this material and tested it for flamability. I am pretty worried this represent a significant fire hazard - especially with the intense heat of my planned 150W hps being no more than 12cm away.
i am going to use a 120mm pc fan - although it is no ordinary pc fan. It is the best - i have tested its pulling power through the filter material and im confident its up to the task. Now I am seriously considering something like an envirolite because the heat is more dispersed and to save me constantly worrying about an exploding hps bulb, perhaps irrationaly.
I am also thinking not all cooker hood carbon filter pads are the same and some will be far less flammable.
Does anyone know of a specifically flame retardant filter pad available?
i'll make a nice pictorial of my creation in the near future!
