Co2 and o2 are independent... meaning just because co2 is high does not mean that o2 is low. The aerobic bacteria are typically what we deal with... AFAIK elevated co2 does not have a negative impact on aerobic organisms but lack of o2 absolutely does.
No I think you thinking about CO carbon monoxide.Thank you for the reply, Aqua Man. I know that above 2,000 ppm CO2 can become harmful to humans, but I wasn’t sure if the levels used in indoor cultivation (800-2,000 ppm) would be harmful to invertebrates or microbiota.
No I think you thinking about CO carbon monoxide.
Nope.OSHA and NIOSH consider carbon dioxide levels above 5,000 ppm to be imminently dangerous to life and health, and several studies have shown lower levels to have adverse acute and chronic effects at lower levels.
The information I found gave different information, but regardless, I appreciate your comments.Nope.
Yeah lots bad info out there. I can assure it what I said is accurate and can be found from osha and others... I think many are confusing it with CO... carbon monoxide.The information I found gave different information, but regardless, I appreciate your comments.
You will need to get some sort of exhaust fan(carbon filtered to keep the wife happy), enough to put the flower room under slightly negative pressure. Air pulled into the room from your house has enough CO2 for the plants until they get really big. You could alternate exhaust and CO2 enrichment, but you'll be battling high temps if you don't exhaust all that hot air outside eventually.Hello all. First time cannabis grower but experienced in other types of horticulture. I’m setting up an 8’x20’ veg/clone/mother room and a 12’x20’ flower room in a garage for a small medical grow and I will be using living organic soil for substrate. The rooms will be completely sealed as the garage is next to the pool and the wife would strongly prefer no detectable odors outside for the kids and/or their friends to smell while they’re swimming.
Since the room will be sealed, I’m assuming I’ll need supplemental CO2. My question is how high of a concentration can I run before causing negative impact on the soil micro biome? I have searched but wasn’t able to find any solid answers. Thank you all in advance.
Thanks. Unfortunately, it’s a detached garage and in winter the incoming air could be -40. I’ve spoken with growers up here that have completely sealed rooms and keep them cool with mini splits. Would that not work? I had planned on using recirculating air purifiers to help with the smell, btw.You will need to get some sort of exhaust fan(carbon filtered to keep the wife happy), enough to put the flower room under slightly negative pressure.
