Co2.

Hey all. (New grower here) So I’ve recently took my shed and turned it into a sealed grow space. The space is 12x10x7. I’ve also recently added the whole co2 sha-bang as well. I’m currently having a few problems in regards to temp and was curious as to if anyone has maybe some tips/tricks to help out.
My temp is 81-86f sometimes can go up to 90.
Humidity is at the very least in the mid to high 50’s.
My co2 sits at roughly 1200-1400ppm.
I’m growing in coco.
There’s a fan hanging from the ceiling, on the floor, and on a table to get lots of airflow.
I was curious if the temperature going that high can result in airy buds or any other complications? I worry bc the last grow I had I stumbled upon a bad heat wave towards the end of flower and some plants ended up with more airy buds than others. Also from what I read mid 40’s to low 50’s seems to be proper so would I be worrying about bud rot as well?
I apologize if the info is confusing, I can try to add pictures to help if needed.
I’m basically just looking for any info on to if I should raise/lower temp, adjust maybe ppm higher or lower, or really anything to help.

I think your trying to run before you can walk (sealed grow space with added co2).
The first thing you want to do, change it over to a normal flower room with an extraction fan, filter and lights
you could take years before you've got the skill set to grow larger crops with added CO2(when the plants are really healthy, environment perfect and you add a little more light, the plants will use more CO2 and grow a larger crop).

but even then, you could better off using a larger flower room.

Sounds like you need AC.
I use a window mount AC to manage heat for my 4x8x8 and 4x4. Co2 @ 700ppm in flower.

A Mini split would be ideal. But the cost goes up.

If venting to keep cool, the ambient intake air needs to be lower than the grow room.

I think I may have worded things wrong. I do have an in-line fan and carbon filter ducting to the outside, I guess that means I don’t really have a sealed room then? Apologies.
when you say extraction fan is that the in-line fan you’re talking about?
the whole reason I want to introduce more co2 is that I heard the room can reach slightly higher temps without having incredible issues, I also borrowed a co2 reader from my buddy and found out the space only actively has about 300-350 ppm co2

I also agree you should have fan venting setup for use as needed.

I actually recently just removed a window AC as I’m in Nova Scotia and can’t leave a unit in during the cold weather and going into winter, And unfortunately I’m running close to maximum wattage so a portable unit is a no go as well

With my ambient air in the 80s or 90s, I'm forced to run sealed with AC.

Hitting 90 in the first 3 weeks is no problem. But I like to finish around 80-82 During the day at the end to make sure they don't get airy or fox tail. I had no problems at 82. Also using CO2

Portable units are garbage. I had a 14kbtu portable wattage pig and doesn't cool for shit. Mini split or window AC work much much better.

Nova Scotia, cool.
Sounds like you have plenty of cold air.
Are you using a temp controller on your fan?

No problem everyone got to start somewhere, no its the fan that pulls the air out of the room though the filter.
in-line fan replaces the air/co2 and cools the room down.

I am using one yes, the in-line fan I’m using is the an AC infinity one with the sensor and the controller

I use the same. Set to auto activate on high temp or high rh.
What's the avg temp/rh of your intake air?

So running your fan at speed 10 does the room overheat?

I actually think based on that explanation that’s what I have. I do not have anything running from outside to pull air in as I have the shed split, so I’ve got the air from the other half of the shed pulling in to the grow space and then a fan connected to a filter pushing it out (that is connected to a smart controller) I really messed up by saying sealed space as explaning this I certainly realize it isn’t sealed. Sorry if this caused confusion

I run my fan at speed setting 7 and it is set to auto. High temp is 80 and high humidity is 60 for it to turn on

I pull air from inside my attached garage (Lung room).
If my garage is too hot, then no fan. I have to run sealed AC.

This is what I deal with...
Indoor is inside my garage.


Not pulling this into my grow. (Rh)

From today.

I guess my “lung” room is not heated nor climate controlled at all. It gets pretttty damn cool there at night and doesn’t really warm up during the day as there’s no light source or anything. Could controlling the climate in lung room possibly help?

Wow yeah that’a understandable I see how that could impact for sure.

Absolutely. Search here or Google and read up on lung rooms.

Yeah controlling the climate of your lung room will make a huge difference.

I certainly will, do you think should I even continue to bother using co2 in the state I’m at? Filling co2 gets expensive and I’m not sure if I even have the climate that’s efficient or optimal.( I guess climate controlling the lung room would help..)
It’s currently 81f and 55% humidity with 1200ppm co2.

co2s not gonna help as much as you think till you’ve got climate dialed in. You’ll be much better off putting that money into dialing in your environment.
