How long does your co2 bottles last?

Recently I had to relocate and rebuild my rooms. My new flower room is bigger. I built it very similar to my last which for the most part is sealed. Some air can leave around the door and where I have the outlets located. Anyway my last room would run through a 20 lb c02 tank in about 5 days. Now one tank lasts 10 days. Maybe my room wasn't as sealed as I thought but I'm not sure how my new room could not use more than last. I will be calibrating my co2 monitor asap.

My room is about 300 cubic feet and with 4 decent size plants I was getting 3-4 weeks on a bottle around 11-1400 ppm. That’s harsh going threw a bottle every 5 days, how big is the room?

If your exhaust fan was running more in the old one this is why

My room is close to 10x17 (total room volume 1740 cubic feet)

1 x 65LB tank lasts me 40 days.

so a 20lber lasting you 10 days seems reasonable. My room is very well sealed. I was surprIsed at how much CO2 those girls could suck up on the daily. Sometimes my room CO2 would get up to 2500ppm by lights on the girls would have that sucked down to 1400ppm in like 1-2h of lights on.

I have my grow in the same room as my hot water heater and furnace and I'm constantly at 1400 ppms I have a burner that only comes on once maybe twice a day. All of this depends on the dead band I set on my controller of course..

Does that make a difference? Will the hot water tank ans furnace increase co2?

My room is right next to my furnace and hot water tank too, but my data shows 0 spikes in co2 because of them.

My rooms never been over 850ppm full or empty

so yeah I’m calling bullshit on that one.

Like myke said, if your furnace is leaking co2 that’s not good and should be replaced Imo.

My water heater has a gas pilot light. The pilot light is a source of CO2 At least when I measure 7418FE6F-4298-46DE-A374-F43AFC2EE44F.png12AA6F69-7FD7-43EB-880A-C5C7D6D29230.jpeg

So you placed that there while breathing right?

Can you leave it there overnight and show me the 12 hour data?

No I held my breathe the whole time.... lol sure it's bullshit. I am trying to trick you.

pulse is back in the grow room now.... maybe another time. DC0922EA-DFDF-477D-AF9E-DE13000DBE75.png

Thats at night with an exhaust fan running but yeah like I have nothing better to do than to make up some absurd claim that my hot water heater gas fired pilot keeps my co2 levels up and I don't know about my furnace leaking any co2 as I haven't ran it yet..

I doubt you'll get a spike as those hot water heaters are vented to prevent co2 from leaking and I see the vent on yours. There's I've had a few gas hot water heaters and I keep mobile and full on carbon x co2 alarms on every per the fire code and never does the co2 change while I'm running the hat water heater. And this part of the building has zero plants it's just a staging area.and the hot water heater is vented.
