    Can I put a timer on hood/fan????

    I'm sure one or two of you ran across this before, what do you think? Have you guys had your hood/lights on a timer? If so does your fan run all the time or just when the temp rises? When the lights are off can I have another, say a smaller cfm fan to run exhaust while lights are off? Trying to...

    I have a 2x4x7 tent, aircooled hood, 6" inline fan, and will eventually buy or make a carbon filter. Given the size of this tent can I get a few ideas on how to hang these items and in what order to install them. Does the carbon filter have to be installed right away, or I can it wait till...

    With this size where are some of you putting your carbon filter,fan,etc. Have any of you put the carbon filter on the floor and ran ducting to the light? Has anyone installed the fan outside the tent? Yeah..I know it's small and maybe I can only get 3 3-gal pots in there. Well what do the...

    Air movement when lights are off?????

    I'll try and keep this short: 2x4x7 tent,400 watt air-cooled light,carbon filter,6" inline fan(530 cfm's)w/ speed control, passive intake. Can I have another exhaust fan running when the lights are off? If so can I get away with using smaller cfm's when the lights are off and just use my other...

    Should the exhaust run with lights off??????

    Hey everyone, I'm alittle confused on this last piece of the puzzle. I'll make it short....2x4x7 tent,400 watt air-cooled light,6" exhaust (530 cfm's)w/ speed control,carbon filter,passive intake. 1st-when the lights are on does the exhaust run all the time or should I set a thermostat on it...

    Damn it's hot in here..............

    What makes you feel that 4"' would suffice? Amount of cfm's? Yes there are flaps on the bottom and was hoping for passive intake. The tent is right by a great window and the exhaust has to travel no more than 5 feet if that. I"m going to use a seperate fan for carbon filter. So do you feel a 4''...

    Any suggestions on exhaust fan.....

    Does anyone have any advise on what might be a suitable 6" centrifugal fan for exhaust for a 2x4x7 tent. Have a 400 watt air-cooled light and will probably have to add a carbon filter later. Are the vortex fans quiet or is there something a little bit better. Thank everyone...........

    more cfm's for intake than exhaust???

    Is it true that you need the intake 2x's more than exhaust? I been reading very many different version's on this. I have 56cubic feet so I'm thinking I really don't need much. Maybe a passive intake with a 4" exhaust and the regular 6" fan tied into my hood and carbon filter. The fan on the...

    So let me get this straight. I'm gonna need two exhaust. One for the light and carbon filter can and another for when the light fan is not on. Will I need a high cfm to move it up and out while I have a couple of small fans inside the tent? Thanks...

    Not sure if this is the way to go...PLZ HLP

    I don't know if you have to have your exhaust fan on all the time. Even when lights are off? Would a thermostat be a way, so as when the temp rises above a certain deg. it will kick on untill it levels out. But what about recirculating air every two minutes or so. Will I have to have another...
