A question for people flowering with co2 and a controller

[Guest]

What do you keep your canopy temps at?I'm normally around 85 F but the more I read on the subject,the more it appears 90 plus temps may be beneficial.I probably wouldn't keep 90 plus temps past 40 days flower but it may be beneficial in the stretch.Anyone doing any high temp co2 grows?

ive always heard 85

I thought more of you would have discovered the benefits of co2

I've always seen it as the last step. The final thing, once your grow room is totally dialed and enclosed, air cooled hoods, all that. I'm working my way up to that, but it'll be the icing on the cake. I just know I can produce much better yields by optimizing the things I'm already doing, like nutrients, going from soil to hydro, getting a continuous harvest going, etc etc.

I run a sealed room with 1K vertizontals, a window AC, fans and a dehumidifier,no air cooled hoods except for veg room.Your right anything thats going to limit your success should be taken care of you must have at least 50W a sq ft and a way to control temps and humidity.

I reckon the person that told me this was the premier growing site after OG went down told me a lie,or my breath really is that bad.

I've heard 85f too. And that's canopy temperature, not ambient temperature - there's a difference.



The room temperature in my setup was at 85f when this was taken, but the canopy temp was only at 78f. So if you haven't got an IR thermometer I'd recommend one. It could be that by raising your temps above 90f you're in reality just getting the canopy temp up to 85f. If you have an IR thermometer then just ignore me

Thanks Sammet It's no fluke I use a Fluke 62 mini,I know how wall thermometers love to deceive!I also noticed during the first 4 weeks of 12/12 when the plants are transpiring like crazy and I'm removing gallons daily from my dehumidifier,you can visually read the plants cooling themselves.Its a trip to see room temp rise and canopy temp fall
