Thanks Bong. My plan is to have two 600's. That blower in particular is in fact made for duct work which was why i was looking at it. I believe there is a picture on the NT website link i posted that shows it linked up and connected to a duct.
I'll check out the inline fans too, but I want something that doesn't require wiring.
Unfortunately I live in a very small town where there is no Home Depot etc. so I'm at the mercy of the crappy hardware store we do have. And it doesn't have much to help hence my need to order! In saying that though I need to be careful what I order and from where because of the nosy people who work at the PO.
If I could do it I'd bring in a grow tent, but I can't chance it.
My plan for the 8X6 is to run two 600's with some CFL's to add light towards the bottoms and use Pro-Mix as my medium. Just getting the two 600's is a chore and I'm not sure yet if I will actually be able to get them!!!


What would you (or anyone else!) recommend, as a simple no hardwire (no electrician!) setup, for a perfectly square 8X6 with 8 foot ceiling room for maximum yield?

When you order from hydro shops, the stuff comes in a plain box and most of the time doesn't even have the name of the company on the return address.

I have ordered all kinds of stuff online, from fans and nutes, to lights and seeds. I haven't had any issues.

The inline fans will come with a cord attached. The "duct booster fans" are the ones that need a cord attached and you don't want to use those. They are for "boosting" your air flow through the duct, not actually moving it through the ducts. The inline fans are made to work under the static pressure from the ducting. Even with a high quality fan you are going to lose a percentage of cfm by running duct work. I had one of the booster fans, a 420cfm, and it blew less air with duct attached than my 130cfm computer fan attached to a shorter duct run.

The area you are growing in will not really have much to do with how many cfms you need. That will be based more on the watts you are using. I could be growing in a 10'x10' area with a 250 watt light or I could be using 4x1000watt lights. With the 250watt light you would only need like 100cfm fan. But with the 4x1000watt setup you are looking at closer to 10 times that.

Makes sense if he is talking about cooling his lights but if the fan is for exhaust/intake the area will be what he wants to go by for air exchange no?

Maybe I'm a little behind the times but one of the only inline fans that used to come with the cordt pre-attached was the vortex..even canfan came needing the cord insalled by the user. And yeah I agree with the ducting runs it eats up CFM in a hurry. try to use smotth elbows and keep them as few as possible.

At the time of writing this I am extremely blazed :P

I've also used those urinal pucks that you see in the mens restroom. They are very strong and will cover up any types of odors. You can find them in specialized janitorial products stores or buy them online. They are like $10 for a case of 12. Your grow room will smell like a public mens bathroom but it's better than the strong skunk smell associated with the last few weeks of flowering.

That's pretty clever. What are those things made out of?
I think I will try the ona mist until I can afford an ozn-jr in a couple of weeks.

just finished my DIY scrubber consisting of activated carbon trapped between a 6" diameter aluminum screen cylinder on the inside and an 8" on the outside. wanted to make it 8"/10" but duct fittings are hard to find in those sizes. put together with self-tapping metal screws, duct tape, and some huge plastic ties. used bamboo/cotton batting instead of polyester because it's less flammable. polyfill used on both ends. the length of the exposed screen is 24". it took about 6 or 7lbs of pellets to fill the whole thing. total cost was about $120 (with a lot of left over chicken wire, screening, duct tape, screws, batting, polyfill, and even carbon). hoping it's enough for my 10x10' room, although there's not a whole lot in it (2x600w).

I Have been very happy with my triple layer smell protection. First off a oversized carbon filter. The 8x39 worked way better then the 6x24, both on small tents. My carbon filter is at the end of my chain (air is pushed through it). The carbon filter sits in a large cardboard box with 6" of clearance all around it, the top of the box stays open. inside the box I keep my cap ozn-1. The cap is on a 15min per hour timer. Last up is a vaportek 4000 mounted very high at the opposite corner of the room. The vaporek refills cost too much but I still recommend it for the peace of mind. The 120 day refill really last like 50 days for our purposes. I have a 70 day old (120day) one I'm still using but you have to be really close to still smell it. For the first 50 days it's great , it even covers cat poop. If you have a safe second room to vent to that no people or pets use I would just run a big ass carbon filter and run one or two ozn-1 24/7, then vent the air right outside if needed. If I could only have one tool to trick someone it would be the ozone. You can make it so overwhelming that the last thing on anyone's mind would be weed.

get a timed mister and use ozium. these are perfect for any small grow and can be found at most grow shops. walmart sells a cheaper version that uses lysol. its only 7 bucks compared to the ozium, but when it comes to this stuff you really get what you pay for. hope this helps! :-D

One question: the activated carbon in carbon filters, is it the same as the bag stuff people are using as DIY? How often do you need to replace the carbon in the manufactured filters? Just trying to gauge long term costs...

hey guys. bare with me. I'm really new at this. How important do you think it is to control odor? Im planning 15 plants. Own my own house but live in a city. i dont have many people coming through my house but occassionally have meter readings, repair men, that sort of thing. Is it a good idea to use a simple thing like the gonzo or something more like air purifiers or other carbon filters? Appreciate any feedback guys..thanks.

need some help on odor control. i never went the homemade route as money was available and to me this is very important. growing in a 1mx1mx2m grow tent with a passive intake and VK Centrifugal In Line Duct Fan 4" for extraction attached to a rhino filter.

listed below is the ratings
vk 4" - 250m3 per hour / 69 liters per sec / 372 pa
rhino - 100/300 mm - 350m3/hour

even with this i still get quite a pungent odor - and im also using ONA pro gel with a fan blowing over the top
can't get my head round why their is still a smell ??? they only thing i can think of is that the extractor is not large enough after connecting to the cf and ducting ( although the ducting is only 7" ) which occasionally creates a positive pressure allow some smell to escape. any other ideas as i really don't want to buy a new fan and filter !! cheers
