whats up fellas...im new to the site but not to the wonderful world of medical growing. i have recently moved my grow from my spare bedroom/bathroom to a 8x12 room i built in my back yard and no longer have the option of central air. my space is limited in my new grow room so a portable ac is my best option. my room is split up in to 2rooms.. flowering room (8x7) and my veg room (8x4). my million $$ question is...if my portable ac has an ion genarator built in to it, will the exhaust out of the back of the ac be filtered enough to let it just blow into my yard with out the wonderful smell of mj roaming into my neighbors yard? im only going to be flowering 6 plants.

From what I understand about portable a/c units with the ionic generator is that is located very close the the indoor exhaust vents. If that is the case then any outside exhaust would not have run through the ionizer. I mab be incorrect but it wouldnt make sense it would ionize air that is going to be exhausted outdoors. If it dose not go through the ionizer then i would recommend putting a filter that is filled with activated carbon (carbon can be found at any pet store or walmart, aquarium section) in the exsaust line that is running outdoors. That should take care of the smell.

Just my 2 cents. Good luck and happy growing.

thanks for the post back brotha.. ya, i kind of figured it was gonna work the way yo described, but i did have hIgH hopes it didnt.
so that leads me to my next question...venting the son of a bitch. my grow room is dug 3 feet below ground level. i dug out the floor because i dont wanna run in to the problem of not being able to move my lights high enough again..it sucks when you got sexy ladies who wanna grow big and tall and they cant because i got a 7.5 foot celing...not the case anymore. which leads me to my question. it is almost impossible for me to properly vent the ac straight out the side of my groom unless i build a 3 1/2 foot tall stand to put the ac on, in wich i really dont have the space. what i do have is a nice 8" exhaust line that runs all the way across the top of the room threw 2 1000w super 8 hoods and dumps into a 8" carbon filter that sits in a shed i have sitting next to my grow room. what about tapping the ac exhaust into my 8inch line right at the wall where it exits the room? i have a big vortec 850 cfm fan at the other end of the line pushing air through the lights. i realize the 8inch fan will not push as much air threw the hoods with the ac vented in to the last 3 feet but does anybody think it will work? will it be to much back pressure and fry both my ac and fan? im no HVAC expert but in my head it sounds like it should work...right? 2 seperate fans pushing air through the same big hole... in my mind the only thing that should change is how fast the air is comming out the other end which shouldnt matter in a 8x22 inch filter...am i right or dead wrong?? come on hvac pros and hook a brother up with some info on the subject. any opinions will greatly help

Yea i dont think youll have to worry about back pressure as lond as you have a spliter thats directional to the exhaust. The long thing that would really be a factoe would be vacuum. The stronger exhaust as it passes by the other will cause a vacuum as it passs. Kinda like a air amplifier. Dyson bladeless fan for example. But if the exhaust line is oversized then i wouldnt take that into effect. If it is pulling it might have a small chance of burning up the a/c motor. But a bigger exhaust line after the tee would fix that problem. Hope that helps or at least gives ya some ideas. Sorry for spelling and errors im typing on a phone and it is jumping around on me.

im thinkin it will work too. jst to draw a picture of what i got it goes like this... 8inch 850cfm attached directly to a hood ..then about a foot and a half of ducting where it goes in to the 2nd hood ..then into an elbow..then into bout 4 feet of 8inch ducting then leads to the wall where it exits the room into about 4 feet of double walled 8 inch stove pipe with a 8 inch carbon filter.
so what ur saying is to turn that 8inch stove pipe that is on the other side of the outside wall into.. lets say 10inch stove pipe and prob should be solved? then the ac exhaust will only be traveling about a foot through the 8inch along with the air from the hoods before it turns in to 10inch
