well that would depend on what you mean by "work" lol.if you seal your room and dont use co2 your plants wont "work" without co2.but if your talking about excellerated growth rates,yes it needs to be warmer than 78f and the co2 is not fully utilized until around 84f.but if all other factors are not on point like celtic mentioned vpd,or nutes,it would be a waste of time imoneeds to be at least 80 degrees for co2 to work
- you do see results with CO2 use ? the product by TBN says 1500ppm in a grow space - b ut is probably a 4 x4 grow space or smaller, Thoughts on ?I agree with the guys on the quality issue with co2 I run about 1000ppm in veg and up to week three or four in flowering then cut it back to 400 to 600 ppm. I am not an expert with co2 but it works for me. If I wasnt trying to seal up and keep odor in I wouldn't f with it at all. My last 24k warehouse I didn't have neighbors ,smell was not a concern so I ran her ventilated with no co2.
As I stated earlier.......this is kind of inaccurate. Your room can be 80 degrees, and if your leaf temps and your humidity isn't in range, you are not doing much to boost anything.needs to be at least 80 degrees for co2 to work
Thanks for information --PEACE !!!!As I stated earlier.......this is kind of inaccurate. Your room can be 80 degrees, and if your leaf temps and your humidity isn't in range, you are not doing much to boost anything.
Case in point: I was running a Vertical tree room a few years back, had LOTS of airflow going on and 5 tons of cooling in the room. I had to run my ambient temps at 79 because my leaf temps were right at 84.
So....like I said.....a laser thermometer is needed to accurately dial a room in.
It's all about the VPD (Vapor Pressure Deficit).
Also, its better to get a laser thermometer and take leaf temps. Your room can be 80, but depending on style of grow, your leaf temps can wind up being 85 or higher. Also take note that some strains respond better to lower levels of co2 than others.
I stopped running co2, and honestly I can see an increase in my quality with the fresh air exchange.
