hey everybody,
If a guy had fresh air pumping into his grow area would co2 still be as helpfull? I have a 4'6" x 9' grow area with 2 400W lights,it gets exhausted through duct work from my basement up and out to the roof,with that said,i still have an old duct line that goes to an out side vent.Would It benefit my grow to hook a fan and pump outside air int the grow room? I have AC to the room so summer temps could still be controlled.Think this would be worth It or should I just hold off til I can swing a co2 set up?
thanks for any advice!
Dux.

I believe you should pump in as much fresh air as you can. Then when you can swing the co2, go for it.

CO2 setups are amazing and can help out a ton. It will give u more bud. But if u can pull fresh air from outside into the grow i mean that would be really good as well and a whole lot cheaper

Gotta agree! seems like common sense I guess...nice fresh air or just basement air..haha thanks for the replies!

while it does provide greater results, c02 is purely complimentary, and not necessary at all. your plants will appreciate a constant supply of fresh air over stagnant air laden with c02. there is plenty of c02 in our atmosphere

im in the same boat as you, i have a sealed 10x10x10 room in my basement. im running all co2 and no fresh air. i refresh the air in my room with the help of a 6" inline fan with carbon filter on the cieling and then another 6" inline fan with carbon filter on the opposite side of the room on the floor just scrubbing the air and keeping it fresh and clean. It is working wonders for me and my plants are loving it! But also like the other people have said, its all personal preference, but if you have the money and can completely seal up your room, i would say use co2! co2 can also help with bug problems. If you ever get mites, just crank your ppms up to 10,000 for an hour and GET OUT OF THE ROOM!

Ambient outside air has about 450-650ppm of Co2. This will help your plants off course but having 1400-1800ppm at 80-86 degrees is where they really thrive. Fresh air from outside can help but it can also lead to a number of problems. Airborne pathogens and spores can get into your grow room along with pests. I would think about bringing air in from outside if you don't need to. If you decide that you want to just make sure it is well filtered with both a carbon prefilter and a HEPA filter.

You put a dust shroom on the outside of your house? We are talking about bringing in outside air; not air from outside your tent or closet. A dust shroom is exactly what it says; to block dust. I use them on the first light in a row and on my air handler. They are only good to keep dust and dirt out. They will not stop spores or pathogens.

bacteria out of your garden!" i have the 10 in. dust shroom

Horti-Control Dust Shroom? Don't tell me you believe the packaging? It's not keeping anything out of your room but dust and dirt. Look at the chemical make up of the shroom. It's not even as good as a carbon filter would be. It is too porous and does not have HEPA quality fabric.

Hey phillip, I just got back from my buddys place. we both run the same strain with the same set up. his plants are covered in PM at week 7 and mine at week 7 have no PM at all. The only difference is that i have the dust shroom on my air in fan and he doesn't. The plants were also vegged at my place before he flipped them.

I'm happy you don't have PM but there are a million other reasons why he could have it. Maybe his humidity is too high; maybe his nightime humidity is spiking; maybe he has spores in his room and walls; maybe his soil is too moist; maybe the environment around where he is drawing in air has plants that have it. There are a number of reasons why he has it and you don't and none of them are the fact that you have a dust shroom. If you don't believe me then fine bro; it doesn't matter to me. I was just trying to be helpful; not argumentative. Keep on using your dust shrooms. Next time you get a chance call up an HVAC person or actually look on the packaging and see what the composite material is. Then you'll realize you were wrong.

Hey phillip, sorry if i came off argumentative, but that wasn't my intention. was just seeing what your thoughts on that. i believe i might be his soil being too moist. i water lightly every other day giving it time to dry up. for him he waters heavy about once or twice a week. thanks for your input also i wanted to ask if it was okay to use a portable a/c if my room isn't sealed and without co2? and where can i exhaust the hot a/c air to? i was told that the exhaust air would carry the smell with it wherever i exhaust it to. would i need a carbon filter for that?

No worries man. How do you mean that your room "isn't sealed"? Are you exhausting air out of it or are there openings and seams? It will make your a/c work harder the more cold air you are losing but their is nothing wrong with it. There are single and double hose portable a/c units. The single hose unit uses air from the room and then exhausts the hot air produced out of the room via the hose so you will get significant odor outside. A dual hose unit uses the hose to bring air from outside the room and exhaust it back outside. Not much if any odor to worry about. They will leak a little but nothing major unless you are venting it to your living room or right in your neighbors window.

yea I'm exchanging air. i have air coming in from the window and I'm exhausting the air out to the attic. I have the single hose portable a/c unit. should i place the exhaust ducting right next to my carbon filter so it just sucks out that heat and smell too? my carbon filter is hanging from the ceiling. any suggestions of any easier or other ways?

I guess that would work. Just don't have it so that it is sucking air through the hose of the a/c. Keep the hose about 2ft. from your carbon filter. If you start pulling air through those a/c units it messes up the motors. Like grinding gears.
