Have i got my ventalation set up right lads if not let me no whats wrong
sorry about the pic im a shite drawer lolView attachment 2549936
what kind of hoods are you using? i think your filter may be in the wrong place its usually on the end of your extraction if you have open hoods, if its a run-through/closed cooling system you will have to set up an extra extractor for your filter ;)

Your filter should be at one end or the other. I personally put my filter at the downstream end so it acts as a muffler. People say it needs to be at the beginning of the ventilation setup but that is just not true. The air goes through the carbon regardless of what end you put it at.

You have open hoods. Keep the carbon scrubber where it is, or you can move it to the end of the exhaust duct. Both places are fine.

no your suppost to put your carbon filter at the end so the air is beingdrawn threw it thats how there designed and why they have pre-filters on them....

You are correct in saying that is what the prefilter is for but they are not specificly designed to be drawn through. The same amount of air is going through the same amount of carbon whether you push or pull. If it is a push set up there is no reason to have a pre filter.

CAN-FAN / CAN-FILTER COMBO SETUP SUGGESTIONS:

You can set CAN-FAN / CAN-FILTER combos up in several different ways. You can push or pull air through the filter, but the outer poly wrap is intended as a pre-filter to remove dust before it gets to the carbon, so it's better to draw air up through the filter. The carbon inside will last longer with a clean pre-filter. The pre-filters are pretty cheap to replace, but you can hand wash them too as needed.MOUNTING FAN AND FILTER:
We don't recommend mounting the fan directly onto the filter, as the vibration of the fan can cause settling of carbon in the filter. This settling may allow air pockets in the carbon to develop at the top, and untreated air to pass through the filter. You can hang the fan from a couple of rubber bungee cords to absorb any vibration and cut down on fan noise. Then connect the fan to the filter with standard clothes dryer ducting (from a hardware store) securing them together with either duct tape or screw-clamps. The filter can then be placed in a dry location either sitting on the floor, or hanging from a ceiling. The length of ducting between the fan and filter doesn't matter as long as the ducting is a clean, unrestricted shot between the two. Straight PVC pipe can also be used for longer distances if necessary. For maximum effectiveness, the closer the filter is to the fan, the better, and we'd recommend keeping them within a few feet of each other. You can get some distance between them if you have to but it cuts down on the air speed.​
AIR FLOW OPTIONS:
There are two really good ways to use the CAN combos. The first is as a 'polishing' filter where you put the connected fan and the filter into the same area together. By drawing air through the filter repeatedly in a closed area, it will effectively keep the air in that area free of odors. This is how they use CAN filters in airplanes, and in other closed environments.

The second way to use the CAN combo is as a pre-exhaust air cleaner to remove odors from the air as you exhaust air from your garden area to another room. You'll need a hole in a wall somewhere for this setup in order to exhaust the cleaned air out. All of the air that passes out of the room through the filter will be clean air. This setup is effective enough to use the heat from your growroom to help heat your home and not have to worry about organic fertilizer odor issues in the house. They use CAN filters this way in hospitals, auto body shops, chemical plants, and many other commercial applications. Remember, that in every exhaust application, you have to have an unrestricted intake somewhere in the enclosure. If you run an exhaust fan without another fan for intake (not always necessary), or without a passive intake (a hole) somewhere in the room, you may run into heat issues. Any exhaust fan is going to need an intake in order to work to it's best ability. A rule of thumb is that if you have one 6" exhaust fan, you should have the equivalent of 2- 6" holes for passive intake somewhere else in the enclosure or room.
GENERAL INFO:
All CAN-FILTERS last from 1 to 1-1/2 years - occasionally longer. The higher your humidity, and the dustier the environment, the shorter the life of the filter. To prolong the life of your equipment, clean the poly pre-filter regularly, and every once in a while shake or roll the filter around to expose new carbon within the filter. Your CAN-FAN will last for many years. We've been selling these fans for about 6 years now, and have never had a warranty issue yet. If you find that you need any additional fertilizer odor control try ONA PRO Gel. It's a good compliment to the CAN Combo if needed.​

i assume your doing a heat exhaust for your hoods. pulling in fresh air from outside and through the hoods wont need a carbon filter so take that out.. put a carbon filter and a lower rating CFM to take heat off the top of the grow room if your gonna use a carbon filter at all...light heat and actual heat inside the room are a bit different. by greatly upping the amount of cool air flow in your hoods you reduce the heat they produce to move them closer to plants which you should be worried about using 600 watts losing a foot of light penetration compared to 1000watters. hope this helps.

carbon filters in my opinion are used just for excess heat in smaller grow spaces when smell is a problem. otherwise i just use a small peice of screen over the intake of my ducts lol best and simplest thing i could think of since it wont make the air flow less and will still keep out unwanted large particles. not that anything should get in anyways if your ducting is all tight and you have glass hinged hoods.

you guys not think smell might be an issue? using same size intake and outake, outake would actualy be weaker then intake considering theres a can on there?? outake should always be more then intake your tryin to create a vacuum so no smell esapes, if it gets too smelly turn ur intake off but keep an eye on the heat

you grow with out carbon cans? wtf. you live on the moon or someshit

I thought the drawing looked ok if the hoods are open, although I've always been taught passive intake and probably wouldn't be connected to the hoods passive or not.
 
The reason my intake is same as outake is because i tried a 5 inch intake and it was not powerful enuf to push air threw both lights for my extraction so ive got a 6 and it works fine so i thought it was right, also is some 1 saying i can have my filter on the end of my exhaust ducting which is in the loft if so i never knew that so thanks. I was going to remove the filter from were it is and have an intake at 1 end of my lights and an extraction at the other end and then hang a 5 inch fan and filter at the top of the tent would that be wrong, would there then be too much exraction in the tent. cheers lads
