Co2 question!

[Bubblegum31]

Hallo guys..

I was just about to buy. Co2 controller co2 generator..

My question is the following

During dark period, if the temps and humidity in check do I need still to exhust or vent at night??

Co2 will be off only AC AND DEHUMIDIFIER will be on..

Is that good enough?

 

[Bubblegum31]

No body?!!

Bubblegum, I vent during the dark in a low setting to keep temp/hum in check. The problem is during the light period when you're pumping co2 and humidity skyrockets. I don't think you should be worried about the dark period, you could vent or not ..i don't think it really matters.

I only vent at night to exchange the air in the room a couple of times since I don't do it at all during lights on.

Hallo guys,

Thanks for the replays..

So 100% sure if I can keep my temps and humidity during lights out.

I dont need.co2 and I dont need to exchange the air..

Correct?

 

[bottletoke]

Pretty much.

Correct?

Is your room sealed? If so your AC unit should/could be recirculating air into the room. Co2 isn't need at night because photosynthesis isn't happening without the presence of light.

Hallo, thank you for stopping by.

I have heard conflict opinions about this issue.

As a friend of me have just told me that I might face a probleem if I dont exhust at night.

Some users have reported that the co2 levels increase at night time around 2500ppm + while the gen is off due to the fact that the plants prouduce co2 during night while consuming oxygen!!

Me my self have thought and always believed that co2 is oxygen!!!!

Some other users sayed that they have experienced clorosis or spots bcz they didnt exhust at night and when they start to exhust at night this probleem vanish however they cant profe that the probleems they had bcz of they didnt exhust!!!

Where the truth is I dont know..

But where Ill start ill not be able to ship filter and exhust kits and I really dont wanna run a nightmare in such setup!!

Ok. Whether or not you have a sealed room is a variable. For instance, I don't need to cycle air in my room because my AC does it occasionally. If you are growing in a tent, you would not need to cycle air in. You also would have a tough time using CO2. So back to my question, are you using a sealed room? Closet? Tent?

 

[Bubblegum31]

Sorry I didnt get the point behind your question..

Its seald room..

 

[xmatox]

Ok awesome. What type of AC do you have? A mini split or a portable?

 

[Bubblegum31]

Split

2x 12000BTU

ok, I would check to see if your split continues to cycle even when its "off". If it does then small amounts of air will be cycled in and should be fine. If it doesn't and you are worried that you need to cycle new air in, you could always put an inline fan with some ducting to pull new air in the room. I would set it on a timer for 5 minute increments, every 12 hours or so.

I just feel that not "sealing" your room could allow for bugs and other friends into your room. You should be able to control everything in the room, i.e temperature, air, wind, water, nutrients... etc. Usually air exchange is for getting colder air into the room or if you need co2

Where Ill start the normal air temprature is from 27c to 37c at any time of the day..

Winter is 22 till 27 and that last for only couple of months..

Me depending on the outside air is usless as its very hot air most of the time..

Even at night my ac will be on for sure if I wanna mentain 27c lights on 22c lights out!

Infact I dont want my ac to get air from outside as I wanna keep equal air pressure not negative not positive!

What do I miss in here!

 

[Bubblegum31]

I dont wanna exhust nor intake!
Its the whole Idea to run tortaly seald.

Just as simple as this!
Does any body do this with success?, I think that would be the right question.. Maybe!

I doubt that if small amounts of air inter the room this isnt gonna decrease my co2 concentration in the air during night period to normall levels again like around 400ppm plus that might infact create positive pressure letting the smell escape the room.

I don't know why you are over complicating things. To answer your original question, you do not need to exhaust at all if you are running a sealed room. If your temperature or humidity changes, your AC and dehumidifier should turn on. I don't understand why you think you need more than that. A sealed room now becomes a "not sealed" room when you vent it...

Brother exactly!!!

I dont wanna complecate stuff! I wanna make it easy as possible but also I wanna make sure I dont fall in probleems..

After research I am 100% that my co2 levels gonna increase above the 1500ppm during lights out if I dont vent!!

Is this gonna be a potiential risk for any kind of probleems!??

 

[xmatox]

No, just gonna end up using a little extra co2.
