Now that I am moving the flower tent into my new room. I have a couple questions on setting back up.

Here is a pic of what I drew up.

1. Should I have the inline fan and the carbon filter outside of the tent and let the duct work be inside?
2. Should I have the inline fan inside the tent and the carbon filter outside?
3. Should I have the inline fan outside and the carbon filter inside?

sorry oz, your a little too quick. I had to edit with the questions. Also, this probably needs to be in a different section. I didnt see a grow room setup section.

thanks

I have everything thing outside my tent. I do this to have more room for plants.

maybe just scrap the scrubbber all together if the smell is not an issue ??

cleans everything. Intakes for tent draw from lung room which in turns goes through tent then to a carbon filter. In fact the carbon filter is actually sitting outdoors.

If room is an issue, then put it outside, but for best results keep it inside. sound right?

people do it both way. but the most used is to have a closed end inside the tent connected to your fan then to your lights then to outside the tent..some people instead of sucking the air out your tent .to mount everything out it would go. scrubber to fan mounted on the outside they blow air into the tent keep your scrubber sock on the the reg way. then on the other side of your tent on the outside you would have a another fan and scrubber pulling air out of your tent, same setup as your intake but make sure that your outtake is pulling air out and that you put the sock on the inside of your scrubber.also be warned that by pushing air into your tent that the smell will more then likely leak out. some pics of my vert grow and reg setup.
here is something to watch so you can see how they do. i hope i give you some things to think about. if you have more? ask were here to help
here the link.http://www.youtube.com/watch?v=VS5eyx_oEzw no i dont own anything they sell own do indorse them. i just like the way they setup their tent. and it very help in this case. enjoy

pulling air is always easier then pushing air. imo the best way is...

(carbon filter > duct > air cooled hood > duct) > (inline fan > outside)
.....................inside tent.......................................outside tent...................................................

Like shortbus said, filter/duct/light/duct/fan outside tent.

you can hang the filter up high so it doesnt affect space, also up high is where the heat sits.

going with no filter is not a good idea, having odour is as bad as telling strangers you grow. imo.

That is what I did. Filter, duct, hood, duct, inline fan on top of the tent pulling air and pushing it out the window.

I have been running my inline fan on low. Should it be at a certain level? Low, low med, med, med high, high? Also, does it have to be at a certain level for the carbon filter to work at its best?

Carbon filters work best in lower humidity, high humidity carbon is less effective. Only run your fan at or below recomended cfm rating of the filter. if you run the fan to fast the carbon will not have enough time to filter the odors.

the temps are right. i dont know about air exchange how can i tell? humidity seems good 20's

Do you know the cfm of your fan unit, is it variable speed? If you are running it full speed use your cfm rating on fan ( cubic feet per minute ), Figure out the cubic feet of your room ( L x W x H ). Now you need to know how many times you need to exchange the air which I am not sure about, I just set my fan to the speed I need to keep my temps where I want them. I see you have a variable speed unit,that makes it easier.

Negative Air pressure is what I always shot for. If the exhuast fan made it hard to open my door,,I knew I had negative Pressure,,which is very good. heck my fan would almost suck my door in if it wasnt secure. LOL I was in Florida at that time and it was hot as,,well you know.

on low it makes the tent suck in. its a 4x4 tent and a 400 cfm fan

Yep,,dont want that tent to ca lapse. LOL

you have a 4'x4'x6' flowering room. so you have 96 cubic feet of air in your flower room. your fan is rated at 400+ cfm(cubic feet per minute). so on the highest setting the fan can exchange the air within your room 4X every minute. this is not taking into account the drag that is caused by duct bends, carbon filters, and long runs of ducting. also carbon filters have cfm ratings as well. so you need to take that into account as well. as long as your exchanging your air once a minute your good to go. i think your fine even if you exchange once every couple minutes.
