How much does temperature affect CO2 intake? I'm running 75-80 lights on and 65-70 lights off.

The how to and why fors of CO2 supplementation for growers

Duckdodger, the answer to your questions are in the links in the first post. You can use dry ice but it's expensive, doesn't last long, and can't be metered out.
Buick455GS (nice car btw) temp has a HUGE impact on CO2 uptake, 85*F is optimal, anything less and the stomata on the leaves aren't wide open, wasting most of that supplemental CO2.

Wow. First time anyone ever told me 75-80F was to cool. Guess I'll have to work my cooltube fan on a timer so it'll warm up a little.

Yep, search for my thread on how to automate hood heat, you can keep it when needed and blow it outside when not. Automagically!
Nice ride man, a former neighbor of mine had a white one, sick ride. 455's are decent motors, just always hated the tiny valves on them (hence the nickname "Nailhead") I had a 68 Firebird with a 400/400 combo, god what a fun beautiful car. I miss laying under it spinning wrenches.

But the more fresh air I pump in the lower the CO2 ppm. The lower the CO2 ppm the more CO2 you have to pump in. Kinda seems like a very expensive circle.
Well you shouldnt be pumping in any fresh air on a CO2 room, but for brief periods (to heat up the room) it should be fine. If you're using an NG burner I'd tell you to hook the generator into a thermostat so it keeps the room at 85 itself, your CO2 PPM may be a bit higher but it's a superior solution. With bottled CO2 or propane it's probably not practical since it burns up tanks faster.

Hey Lazy, how would I incorporate an emergency intake and out if in case my power fails? Would motorized dampers on emergency surge protectors (like the one's they use to keep computers on during power outages) work? Power outages are common in my neck of the woods... in fact I had one yesterday.... A few minutes with no fans or exhust in my 4 x 8 hydro hut back in the day use to reek havoc! I don't even want to think about what an hour would do in a sealed room!
I seen those dampers And they don't look all that much sealed.

Yep a couple fans on a UPS or two (see apcc.com) would help, but your lights will go off too so there won't be much heat to deal with. I bet it will be expensive to get the runtime you want though, those critters aren't cheap! You would still want the fans to have a thermostat plugged into the UPS so they don't run unneccesarily.
Lazyman I am back for your opinions and thoughts.
I purchased and set up a sentinel cppm-1. Sweet unit from what i can tell. I have not set up the tank yet but i am reading the CO2 content in the room. I have the door open and the room(almost sealed) has a slight negative pressure. The exhaust in the room next door(veg) is causing it.
My point is that my cppm1 is reading between 600-1480ppm on its display. With the generator not yet powered on are even connected????
Anyone got a clue as to why this may be happening?
Thanks much

Hmm, where does the veg room pull air from? Anywhere there's a gas-fired appliance? Did you calibrate the sensor per the instructions? It's unlikely your atmospheric levels are in that range unless one or more of the above factors apply. You'll want to seal those rooms off better to keep things stable, it will drive you nuts and waste CO2 otherwise.
well the house has a gas dryer and a gas range but they are rarely used.
I have been trying for days to seal the room completely and its not going to happen i think. I put up a tarp with a zipper after i weathersealed the door and the tarp is sucked in when everything is closed.
Its a major bummer as i have spent many hours constructing this space. I believe the culprit are the two fans in the veg space. I installed a window AC in the wall between the two rooms and it has a 10 inch fan added to its outake duct to help move the air through it. This fan is somehow sucking air from the flower room. I triple checked all seals today and used about three rolls of foil tape. It visibly reduced the tarp on the door from pullling in, but it is still doing it. I also put the 10 inch fan on a controller and turned it down about halfway, which may or may not hurt my AC flow and then my AC's condition in general. That reduced it some more.
The only obvious hole is where my light's wires go through the wall into the veg space. That hole is stuffed with tape and triple wrapped and is not even visible to the naked eye. Seems small for the pull happening on the door.
Any tips for sealing up better? Thanks for sharing.

Hmm yeah chasing leaks sucks! I find doors are one of the biggest culprits, I like to use a sheet of panda on the backside of the door and overlap it quite a bit, and seal it like origami on the back (so the door can still open and close, but with a big flap on top/bottom that fold in)
Cans of spray foam are handy for chasing smaller leaks too, but it gets messy, wear rubber gloves!
Did you say your AC is mounted in between the two rooms? It doesn't actually touch the flowering room though right? Just having a little trouble envisioning it.

Door sweeps are like ~$3 at Home Depot. Priceless little strips, really.
well the AC is cooling the flower room and yes the front is in the room. the back is in the veg room. the back has a box built on it to send the hot ait into the attic, and pull the coil cooling air from outside. I'll take a pic if that does not help. Its a 25,000btu Frigidaire and has a vent for fresh air, or not. I have it closed.
I have a tarp with a tarp zipper gorilla taped to the door opening and a piece of wood on the ground that the door sweep on the door comes into contact with. I also used vinyl weather stripping on the whole door which sealed up the light leaks pretty well. On top of the tarp is some panda to light proof it.
Yeah chasing leaks sure does hamper the mood. Oh well, chase i will.
tips were and are appreciated

turns out my AC is sucking air out of my room and out its exhaust. The vent is closed but its doing it anyway. Its a 600$ Frigidaire and i just tried to take the front apart to fix the problem and could not get anywhere. Anyone ever take the back of an AC apart?
