I Need Help

I have a question about ventilation. I have one vent (1ftx1ft) located at the ceiling that is directly linked to outside. The room size is 5ft x 2.5ft At this point I know i need to use this vent as my exhaust but also can i use it as natural intake? as the vent is located so high up in the room.

thanks all

You're missing the third room dimension.
You COULD use that as intake but it would require the vent to be split and the ducting to make it acutally work would be pretty much a pain in the ass. Try an intake from the living space in your home instead. If you are worried about damaging doors, get a used closet door and cut a hole in it, then put the old one back up if the in-laws come to visit lol!

great idea stinkyattic thanks alot. i never thought about doing it that way i think it'll work perfect. im still in the planning stage so don't be surprised if theres more questions from this 1st timer. thanks again
:rastasmoke:

also any suggestions for a good inline fan with variable speed for a 3 x 5 room? preferably one located easily.

I'd go for a fixed-speed fan on a thermostat instead. There's something suboptimal about variable speed ones that I can't recall at the moment... :stoned:

stinkyattic you know of any good reads on here to help me get that job(fan wired to thermostat) done thanks again for your time and help.

I'm going to guess that the best place to look would be in 'growroom setup'. There are thermostats for sale through greenhouse suppliers that are designed to take the conditions found in ag applications, and have a built-in grounded outlet that you can plug your exhaust into- you then set the 'upper temperature limit' to 80-85 and the blower comes on when your temps rise, and goes off when they return to normal.
The way I would set one up is to have a permanent exhaust moving air out constantly, and a secondary one that will quickly remove a LOT of hot humid air. But that is a rather complicated way to go about it in a smaller grow; honestly IMVHO you are far better off just to set your exhaust to 'always on' to not only control heat, but force fresh CO2-laden air back into your growroom 24 hours a day. Your plants will thank you, and so will your wallet. Once you get into CO2 enrichment, fans on thermostats to quickly drop temps in emergencies make more sense, since 'always on' would waste gas.
I'm happy to help, and good luck!

another quick question for you sticky. odor control is #1 importance for me so i am looking into a carbon scruber(filter). now will a fixed speed fan hook up easily to the scrubber or is that when you would have to use an inline fan? thanks again for time and advice

The trick is to find a filter/scrubber that will mate to your fan.
So an inline 'muffin' style blower with a 6" port will take a scrubber with a 6" opening. When you start shopping for these components it will be clearer. I'm so glad you are starting now, so you can look at the air-cooled hood if you run one, exhaust fan, and scrubber as a single unit. They are all connected, and it's most efficient if you get all the same diameter ducting for them- reducers cause turbulence, and turbulence reduces air flow.
If you are looking at a specific hood that you think is just totally the cat's ass, and it happens to be a 6" duct, your life is super easy because 6" components are REALLY REALLY common.
Also, choose your scrubber carefully. What is important? Do you need heavy duty control for a super smelly strain? Or would you compromise a bit of odor control for cheap cost and ease of disposal (=urban apartment, don't want to be seen walking down to the dumpster with a big can filter haha)? You have a choice between a rigid can filter and a fabric type like an odorsok.

see the vent is not going to the best spot it is heading right towards the garden next to my front door.Is there any outdoor plants that i could plant to mask the smell. the cheaper scrubber would prolly be best for me. also i was curious will there be a noticeable difference in hydro bills with going from normal to running my scrubber, fans, lights?thats the only thing in my mind being this my first time growing and such.

getting back to my set up i am using my buddys existing lights, soils, etc but we will be making the ventilation. I believe he has a oscillating fan for air movement. im sure the hood he has isnt cooling so i was just gonna mount the inline and scrubber above the lights. so basically we need to purchase the inline fan and scrubber and run the ducting to the vent. also another thing im looking for in the inline fan and scruber is hopefully they arent too noisey being that the vent is right by my front door. i think were getting most my questions answered. too bad i cant think of them all at once haha. thanks again sticky
