Okay here it is as it stands. My can fan seems to me like it will be fine where it is and shouldn't cause any problems. Everything is complete except for the other vent of my reflector. I'm unsure whether to vent the air back in my room or out of the window box I made....Any advice? The room is pretty large...How is it looking? I plan to partition off another side but probably not until some time in flowering.
Well, the idea behind a vented hood is so you can dump the heat from the bulb somewhere else, like outside. If you have to exhaust into the grow area, you might as well take the lens out of the hood and let the rest of the photons through. (Be careful about the bulb, then--no splashes). Depends on whether heat helps or hinders you.
The filter will work fine like that. The closer to the floor the more kicked-up debris is going to foul your prefilter, though. Most folks prefer to suck through the light rather than push through it for a couple reasons. If you were venting to outside, you could go filter> light > fan > outside and do it all with one hole. Make sure the hood and ducting are airtight or you'll suck smells in after the filter.
And keep those ducts as short as possible. And minimize bends, particularly sharp turns. Solid ducting's got a lot less drag than that dryer-hosey stuff.
Gotta go, HTH.

Good point about the fan sucking up more debris from the floor I didnt even catch that; however, I think it will be fine where it is. I suppose I'll connect my vent to the window box and hopefully it wont cause any problems with shaky blinds or steam coming out my window. Thats a big problem.If so, i"ll have to find a way to vent in my room. Its a large room for only two plants plus with a/c heat shouldn't be a concern. Thanks for the advice man anyone with their two cents - comments, tips, advice, it's all welcome!
