opinions and advices about my new grow room setup and design

Hello, I, am building small grow room arround 5 m2. It is almost done and my plan is to grow only autoflowers in this room. There are several things which concerns me and I need opinion and advices! I am attaching picture with the project.


- My first concern is about the CO2 supply in the room, as I still dont have CO2 meter I dont know if the CO2 will be enough if I use the method for refreshing the air every 2 to 5 min with ventilation system.

I have also an option to bring air flow with fan from sewerage pipeline (there should be plenty of CO2) as there is outlet pipe in the room but I dont know if this will work at all.

- Other option will be enclosed environment with AC and CO2 supply with bottle and valvle but then I dont know if my lights will be enough for CO2 enrichment.

- The other concern is that one of the lights "Niello M600" is from that kind of first LED lights wich contains Blue and Red diodes but this have also UV and IR added, so will there be a problem when mixing the lights ?

If you are going to run CO2 you definitely want sealed with AC and bottle gas. Venting your gas is counterproductive.

Sewer gas fan? Eh? Just scrap that idea.

If you are going as far as design and build with CO2, buy a modern high quality light. There are many LED companies out there making excellent lamps.

Why autos may I ask?

There isn't a problem mixing lighting, but there is a problem accounting for how much light you require since the old blurple will be significantly less efficient than the modern leds.

it looks like your using the doorway as in intake and exhaust point. Which could be problematic.

you don't want your fresh air going in getting sucked straight back out and you don't want your hot humid air going out getting sucked straight back in.

autos- dont need co2 , agree with ^^ @coreywebster regarding door, remember less is best with autos, 1/2 strength nutrients , let them stretch for the lights

is the sewage pipe actually hooked to the sewer? or is it an old stub that's just still there? you definitely do not want to be blowing sewer gas into your house.
and it does seem like kind of a waste to use co2 on autos, and to vent the co2...co2 is usually run in sealed rooms, with higher temps 10-15 degrees higher.

I would think the hydrogen sulfide spewing from a shit pipe is a non starter.
Plus room is over complicating things for just autos.
Run a simple 2 tent setup / 4x4 and similar.

then …. If you want a room. Pull tents out ( not a big deal ) and hang light rigs from ceiling .

Be aware that toxic shit ( pun intended ) is lurking down in the sewer.

One more thing - “ Swamp gas “ as it is commonly known ( eggy smell ) is highly explosive and flammable so heaters and lights ( probably bad idea ) .

Sewer pipe line for co2 intake bad idea that shit is explosive that y it's vented through ceiling.

Plug that sewer pipe, breeding ground for molds and pathogens.
