hmmm .. seems like you got plenty of questions .. and not a lot of info ..

do a lot of research please ..


but in general .. filter have to be same size or able to handle bigger vent.

and atlest 4" .. that is if you plant on running LED or Tubes/CLFs in ther .. or maybe a small 150-250W HPS ..
I would say 6" if you plant on running a big HPS in ther ? (+400W)

guess you are if your asking for a cool tube set up ... my advice .. use a littel extra money here on a 6" with speed controle .. dont think you will regret it .. heat in a small place is no joke ..

and about cool tube ..

I just build mine:

my room and how my 600W HPS lookd before:

and sure you can take your HPS appart .. but please be carefull .. use comment sens and logic .. and dont plug it in while you touch it .. keep a eye on it fist time you run it .. keep a fire allarm close by your room aso.

like the heat a HPS make (400 celcius outside the bulb and even hotter inside) the AMP is also pretty high a deathly if you mess with it ..

so if its totaly uncommen for you to work with electricity and you maybe have 10 thumps aswell I wouldnt advice it .. get some who know about it to help you atlest ..

if its to mouch for you .. you could go the way StraitJacket did .. with open tubes .. might not be as effectiv as a closed tube/hood .. but it do get the job done .. think he said it did lower his temps a few degress celcius ..

a hole on top of your refletor with a pice of tube to your vent might work .. as it will pull most of the hot air away ..

and as I said before .. heat with HPS lamps is no joke .. so good to see you atlest do some research here .. a lot dont take it seriously ..

I live in Denmark .. Scandinavia so we actualy dont have that high temps .. tho summer is here so 22-30 celcius is commen ..

and if I have lets say .. 25C out doors and its a sunny day .. I can easily have 28C indoors wile sun is on ..
and with 28C ther can easily get up to 33C in my grow room .. dont like that .. why I build my hood .. hopefully it can get my temps down them 2-3C


btw
ventilation is not only to keep temps down .. it also provide your plants with fresh air/Co2 .. witch is atlest as importent as keeping 76-82F

I read in another thread somewhere that venting for fresh air /co2 is a myth as either the roots or the plant uses co2 maybe in the dark period. So should only be done if temp is a major deal.

I do not know if this is true or false, someone else jump in and fill in the blanks please. But hey, I DO like talking about this stuff ;)

thanks to all who added info to this thread..

Would it be better for me to use glass or perspex tubes.Im finding it hard to locate a 6" OD
bake a round glass.Im looking on e-bay but no luck.

@slipon

why dont you rewire the ballast to be remote? and did you use foil hvac tape or duct tape?

why didnt you make the hood wider since you already built it your self? did you use glass or plexi?

all in all a very nice DIY, just some critique should you want to rebuild it in the future. i think your hood would be better suited for a 400w or a 250, but work with what you got! well done!
