if you have a basement , why dont you vent into the sewer line ?
Was looking at that yesterday.Did ya just put a y-pipe inline with one side running to your room?Any problems with sewer smells since you hooked up to it?

Fist time grower and poster here. This is a great idea and although i don't have the time at the moment to read thread for a response to my question i'll just throw it out there.
Has any one tried this with small computer fans? I'm building a small room, and will be starting with just one plant. So i'm going to try 2 comp fans for exhaust and 1 for inlet. I am wondering if fans will push air through these or burn up trying? Any thoughts would be great. And KUDOS for a great forum , just what ive been looking for.

Thats a good question on te computer fans,im not a big fan of using comp fans though,their build quality is questionable for our purposes & in no cases are they meant to be ran in conjunction with any type filter or anything that would restrict air flow.

Another thing ive noticed about computer fans,this came to me when i was messing with a regular window fan in my bedroom,my wqife bought me a new fan for the room,i put it in the window & couldnt feel shit & it was on high too,i got to looking at the slim line design & the twist to the fan blades was minimul in order to keep the slim profile,this resulted in very little air being moved more than a few feet past the fan,my old fan had a very deep twist to the blade & could be felt from all the way across our bedroom which is 14ft.

Every computer fan ive ever used had that same very slight twist to the blade,im not sure they are fit to move air in a grow op unless its a very small enclosed cabinet,not because of lack of cfm but lack of their ability to throw air long distance,something they were nerver designed to do from the start.

FYI you can buy 4inch,6 inch & 8 inch inline duct fans at home depot for $20 for the 4 inch models,$30 for the 6 inch & $40 for the 8 inch models,i know for a fact that these type fans move asir long distance because i use them & the filters will work with the inline fans.

Hey Pan, + rep. I have one of these:


I have it venting down into my CrawlSpace. If I slap one of your filters on the fan, you think that setup should work? I have one of thses also in my room to scrub the air prior to extraction. http://www.airreactor.com/prod_mightymite.htm

I have to make this as smell proof as possible

Oh, my room is 4X5X7. I will have 4-5 plants at most.

Thanks for the info. My issue is that i don't have a lot of room. My setup will be in a little room in my basement. I have a full bathroom that has a attached room. The room is actually under my front hallway. So as you can see no where to vent out of the house. No way to vent through the rafters into the plumbing vent either. The front hall was a addition to the house. The room is all cinder block.The broke out a 3' x 4' section which has a door in the bathroom. My Thinking was i could attach to fans at top of door for exhaust and one at bottom for fresh air. But no room and or place to exhaust to. Am trying to figure out a way to just vent into bathroom with odor free air.. Any thoughts????

Im gonna make myself one today. Ive been using a carbon furnace filter. My house starts stinking after about a month with it. Would like something to last the whole cycle long. This just sounds awesome. Will have to figure out how to integrate it with my setup but shouldnt be too hard.

I'd bet it would work just fine in your application.

Ok so I built this from scratch, I used a pc fan....I found that if I keep the closet closed 24 hrs that the filter dosent work...BUT if I open the door for a few minutes the fresh air replenishes and the filter works great...No I didnt have an exhaust system, only the opening and shutting of the closet door. What a difference it makes.......I guess the carbon needs new air or it can not take the smell away....WTF...learned something! Great post btw!

I bought 2 of these, and each quit working after a few hours. I wondered If I got some with a bad batch of motors. I have thought about trying them again. They are certainly less expensive than some other types of inline fans.

I find that so far my home made carbon filters only work for about a week. then they start to let the smell threw.

I haven't tryed this style yet, maybe I will try it next.
You can reactivate carbon. Just place the filters in a microwave and dry them out. Been doing it that way for years for my saltwater fish tank and it does work.:mrgreen:

Hey pan, i have read this forum since page 1, unbelievable that you kept up with i for as long as you did. Thats what i call dedication. As for this fan, whats the wiring like on it? I saw one online actually coming with a plug... but can you hook this one up by splicing it to an extension cord?

great idea by the way and thank you

I went and got one of these and a 6"-4" reducer duct put a few filters in it and duct tape them in the middle then tape the two together and viola. you have a can filter and fan combo for about 42 dollars sweet I know they are about 150 at a hydro shop. also if you glue the scotch towel together I am a fan of loctite stick n seal they look like I should manufacture them and sell them and you don't have to have needle and thread skill. I love you pan but I am a lazy man.

hey panhead i had a quick question do these homemade filters resrict airflow the same as the big air filters or are do they allow alot more airflow

Hey dhh. I just got my filter going, and it all depends on the thickness. I had temps dialed in at 68 at night and 80 during the day. Once I put the filter on, temps rose to 95 lights on and 75 lights off. I am getting a booster fan to help the airflow. So yeah, they restrict airflow. Make sure you have a good fan. If it is rated for at 150CFM, expect a drop to about 80..... My fan is rated at 250, and I am sure it halfed the efficiency... But the odor is gone...
