i think the title say it but i’ll add details.

i’m running 2700W of LED total atm and about to fill in the last space available in my 14x20 with another 800W putting me at 3500 total

i’ve been doing research and apparently with this much light my plants will be in dire need of co2 since im running a sealed room and the only air being brought in is thru a mini split AC and window AC.

so i ordered both of these to add co2 to my garden 8A3926A6-2FD8-479C-926D-B42D543E4C5B.jpeg311CFBB2-E489-4E70-91DD-30D03FC711EA.pngA402F0E9-F873-406E-983D-295C4B0D26E4.jpeg

also i read that co2 burners cause RH spikes as well as put off a lot of heat when they run the burners. is this true?

Once you plug in the controller you will get an idea of what your working with. I haven’t used a burner (i have tanks) but I’ve heard they can dump some heat.

im a newbie with Co2. From what I’m gathering is we need to first dial in the temp, RH, and VPD. Then we go crazy with the co2.

so once my controller/meter/monitor arrives and i set it up i’ll have a reading on my co2/ppm levels

therefore i’ll know if i need to add co2 or not and when. i think it’ll be beneficial regardless.

There is NO outside air being brought into the room through a minisplit or window AC

If you're gonna run in a sealed environment, you'll need a dehumidifier(s) as well

i have a 30pt dehu rated for 1500sq ft running @40% setting 24/7 and i’m about to upgrade to a 50 or a second 30 to make up for the extra humidity that’ll come from the co2 burner.

thank you for letting me know

unfortunately there’s no other way for me to bring air into the room without letting bugs in so i have to run this way.

You'll need a lot more dehuey capacity if a room of that size is populated with plants.

I don't follow
How does a window AC or minisplit AC allow outside air into the room?

The most important thing about bringing in co2 is making sure the room is completely sealed from any other living area
Safer to just use outside air

as i typed my reply i see how illogical that is.
so my only way to increase co2 in my room is with a burner or system since there’s no actual intake on my building to pull fresh air in.

but when it’s cooler outside i can turn my window into on fan and it’ll pull air from outside correct?

i plan on using the co2 burner system minimally. and if it doesn’t workout i will just sell it and move to the next option. i have a good feeling though.

i have a space sealed up in the corner of the room where we cut the wall out for a window unit to be in all year around but it wasn’t sealed properly and water was getting in so i took it out to prevent mold and other issues. i’ve been trying to think of a way i can use that port to bring fresh air in but cooled. because i can’t just reverse an exhaust and pull that hot air in my grow. and then again i don’t want anything open like that because i don’t want to let bugs in.

very unsure on what to do aside from introduce a. burner to the grow.

who knows i may be worried and putting this effort in for nothing. when i slap that monitor up i might be perfectly fine on ppm levels

we shall see. i appreciate all of you helping me out
