ventilation ideas

[dizzy]

Hi, i've got a 400w hps bulb that i'm testing in my grow cupboard (500x750x1500mm) and at first observations itt would seem to create too much heat for this area.. my question is would it be possible to run this lighting wattage with a good ventilation system, and what would i need in terms of size, 150, 250mm fan? i'm looking away from cooltubes except for a las resort.

any advice would be greatly appreciated,

 

cheers, dizzy

Doubt you'll get away without a cool tube in that space...

yep i would say cool tube would be your best bet and also the bigger the fan the better. i also find that the bigger fans can be quiter too

thanks guys, the main reason i was going away from cool tubes is because the light is already connected to the ballast in one piece and i would have to dismantle it completely...
