Cabinet setup....FIRE HAZARD????

ok so i decided i am going to have to grow at a place where i will not be regularly maybe 2-3 days out of a week I will be at grow location. I want to go with a 6 ft grow cabinet and hydro system one plant. I will get a cool tube with inline fan along with timer lights on for 11 hours... I will be using clones str8 to flowering........ do you think this is feasible and should i be concerned bout fire hazard? I will be getting top of the line stuff so i will not be rigging any think... what do you guys think.

i dont think so, i have a grow cabinet with 4 plants and its only 4 or 5 feettall with a 600 watt hps in their(and fire detector) its been like a month and a half and no fire to date.

I had a similar concern with a cabinet I built a while ago. I put a bathroom exhaust fan inside the cabinet up high (exhausting the hot air through the wall of the cabinet) and intake grates down low. Then I started to worry what would happen if the fan ever failed. Solution? A commercial grade t-stat that can be set to open up power to the lights if the temp got near 100 fah. You can probably use a cheap electric baseboard heating thermostat which you can get at Lowes or Home Depot. Just make sure that you have a wide range for differential "cut in temp" and "cut out" temp......maybe 10-15 degrees. You don't want to shut down lights when it hits 100 (or whatever you deem "too high") and turn them back on at 98. OR...if you're electrically savy you can set it up to "lockout" once the t-stat hits the danger mark.

i have a similar size cabinet with a 1000w of lights.

I think you'll be fine but you should follow gohydro's advice and get a thermal shut-off switch.

do you guys have any links to extra quiet fans i can use for my grow cab?

i haven't heard of any quiet fans (even the ones that say they are). I have heard (not tried!) the following tips that may help reduce fan noise:
1) use dimmer control to slow it down
2) use rubber grommets/washers to dampen vibrations
3) use bungie cords to mount the fan to reduce vibrations
4) limit the amount of ductwork and/or use the non-collapsable kind to reduce air noise

so how about i use sheet metal duck the 6inch round kind? the cool tube that I am going to buy is 6 inches in diameter which would fit well into a 6 inch round sheet metal duct.... what do you think? because the it seems that from what everyone is saying is that the flex duct is not conducting the air to the point where there is very little sound.... do you think its worth a try to use?

The lowest resonance noise ducting on the market that i know of is the type that comes pre insulated,just like this.
