Temps With 1500ppm Co2??

I have read that research suggests that the most gains are seen with temps of 90-95 degrees and 1500ppms... some others say 85 degrees is optimal temps, while others still say that 75-78 is ideal...

who grows with co2 sealed rooms and what are your experiences with temperature?

I dont use CO2 but i do know this, DONT run with 75-78. Thats ideal for normal CO2 rates, you need to turn up the heat just a tad when you turn up the CO2.

Im not sure about the 85 or 95 though. Id just stay right in the middle if you dont get any good replies. Stay right under 90, and if they start to wilt you know what to do. Good Luck, Lamp.

ya i know that when the temp is raised it increases their respiration, and allows them to use more co2, but im just wondering if it would be possible to run em that high, and even have ppms of co2 at like 2000 with even higher temps... unfortunately there is not much out there about documenting co2 and the differences it really makes and under what conditions

1500ppms is plenty


2000 is overkill...may harm plants and is just wasteful, imho

i agree but what i am trying to figure out is what is the ideal temp and ppm for running a room with co2, and do increased levels allow for higher temps or is there a ceiling to what the plants can use?

the problem is that right now with my room vented it stays about 78-82 degrees but when i turn off the vents and seal the room the temp goes up to about 92-95 degrees.. and i just bought a dual co2 reg, 2 tanks, a sentinel co2 meter and some other goodies to run co2, so i am trying to figure out if i need to get an ac and run it in intervals into the room, or if i can just run an intake once an hour for 15 mins to keep it in the high 80s low 90s..

but i cant find many documented grows with proper co2, and there is not a terrible amount of reliable info out there, so thats why im here hehe

the guy that goes around grow rooms in canada the urban grower has documented rooms easily running 1800ppms so im confused

wow! i have the igs220 but i want the sentinel chhc-1 SO FREAKING Baddd...i have a few sentinel controllers and digital timers...i love those things...freaking bad ass.

In my humble opinion, when you said you seal up everything you get 92-95F or somewhere around there...that sounds fucking perfect just about to run that 1500 ppms

optimal co2 in normal air outside is around 300 ppms...this is why they tell you to run 1200ppms on your system and with the intake coming in from the outside it will add and give you 1500ppms total

As far as your ceiling question, im not 100% sure, but im sure there is a ceiling....and im thinking that would be around 2000-2500ppm....but like you said some growers claim success with that...but i think in order to benefit from 2000ppms you need to have everything right especially temps. This is another reason why I dont think its worth the cost of wasting gas nor do i think you 'll see any more benefit from using the 2000ppms as opposed to the 1500ppms...but then again i could be wrong. Once you supply it with that many ppms of co2 you have to make sure you are feeding more, they have adequate lighting to be able to digest all the co2 in photosynthesis process.

I would run cycles of 1500ppms....let the plants soak it up for 30 mins to 1hr with the exhaust turned off, while leaving the intake turned ON. Then i would cycle the old used up co2ish air out (exhaust on) and refresh with more co2.


its always trial in error. The key is dialing it for your specified op.


Hope that helps

i just got the cppm1 but if it turns out to be a good quality product, i plan on picking up a few timers and other things from sentinel.

now why would i intake and exhaust more air? the plants will use up the co2 and replace it with oxygen, which would make the controller pump out more co2 to maintain the levels... it seems to me the only time i would want to intake or exhaust is if the temps got too out of control right??

and man if low 90s is ideal for 1500 ppms then im gonna have an interesting grow hehe im excited!!

that is just my opinion of course


and the reason i would still intake is because fresh air is fresh air. you would exhaust at the end of every cycle to exhaust old co2 air. that is when a controller would then kick in to push in fresh co2 @ user desired levels


sure you could only exhaust when the temps are too...which normally does...but some folks do it x way others do it y way and others the z way.

honestly if you have the right controller i would definitely let it work out for you. thas why i like my igs220 so much.....but i want the sentinel chhc-1 that is one baddddd bitch. My igs220 is the same thing, except i dont have an external sensor device/probe thingie and i put tape over the lights cuz i dont want shit to hermie. The CHHC-1 on the other hand does

here's the CHHC-1 demo:

hell i may just 2 of these...i want one for my cab for sure.

the sentinel drt-1 is a bad ass recycle timer too.....programmable down to the second! love my sentinel gear.

i dont think you'll be disappointed

i could probably exhaust a couple times a day for the hell of it.. tweak it a bit..

ya that is a bad mofo, i just have the cppm1 but its still nice, now im wishin i woulda spent the extra to pick it up lol oh well, i can get one for my other grow i suppose hehe..

so u think the plants will be thriving at 90-95 and 1500ppm with rh in control?

who else has some experience with co2?

thanks again loudblunts +rep

anywhere from 85F on up is good imo...(any less would be too cold)

i wouldnt go higher than that 95F though


and no problem, glad to help

also i was wondering if my room temps are up there like 90 degrees, my res temps are going to be pretty high as well... wont this cause root problems? or do i need to buy a res chiller too LOL

yes i have co2...i have tanks with the igs220 enviro + co2 controller.

however, im not currently running it, i want to reassemble and/or upgrade some things a little bit. i may use the igs220 for my SJ DarkRoom..... and buy a chhc-1 for my cab...not sure yet.

when i ran temps it was around 83ish to 85 all the way up to 95F

i like to play around and experiment a bit....i sometimes find with mid to high temps (high 80s low 90s) encourage more water uptake anyway....

as far as your res chiller questions, in short.....yes.

any hydroponic reservoir, imo needs to be kept at 60-68F. 65-68F is the sweet spot.

res chillers are pricey, but man can they save your ass and produce nice pretty xrated type root porn and buds

man that sucks LOL maybe i can just improvise and throw some of those freezable ice packs in there every day.. or run a garden hose coiled through a bucket of ice.. is the res temps more to stave off pathogens? could i supplement with h2o2 every few days

sure of course you could freeze water bottles (i wouldnt use those freeze packs thingies) and put them in there.... are your roots hanging in the res at all? or you still going vertical with a big res?

well shit yea, freeze a whole 24 pack and keep dumping every few hours......be warned: hella tedious.

be better off getting a chiller. more consistency equals better results

h202 does not fully kill off anything. it just release that extra and oxidizing (or something)

anything over 70-75F in the res is asking for trouble. basically breaking ground building a hotel for pathogens and you've just had a grand opening party with 50% off on all vacant rooms (of course while they last)


physan 20 is good if you ever have serious root rot/pathogen problems.

but you must get that res temp right. other systems (aero, dwc, etc etc) may be MORE picky about it....but all hydroponic reserviors need to be light tight, chilled, solution moving

ya i am going vert with a small res lol its only a 50 gallon but its the largest my room can take.. this means i am constantly putting in fresh cold water and adjusting ppm ph, so the res stays nice and healthy.. ya i did a lil research and since my temps are always 72-80 i guess i have always been in a good place as far as res temps go... having the co2 and the increased temps is gonna fuck with me tho

im doing the vert with the hugo 6x6 rockwool blocks, but i think i found a good diy chiller from a watercooler.. i can get my temps down 15 degrees or so for 25 bucks which would be nice.. id love to splurge and get a chiller, but i know im gonna be changing up my system soon so i wanna wait it out.. guess i gotta tackle my new problem, res temps lol

I don't think you will have root problems but alot of evaporation lol.

Water reservoir temps can safely be between 66F and 82F.

im not sure what my res temps are, but usually they are about 10 degrees below ambient if they are on the ground.. ill have to get a thermometer and check..

i have a smaller res that i top often, so im thinkin i may just get a few large soda bottles and drop in the frozen goodness every few hours.. ya its a bitch but i dont have the space for a chiller right now, and my temps are already gonna be high, having a chiller is just gonna put the heat back into the air...

i think if i put some frozen big ass soda bottles in there, along with heavy aeration and h202 it should be good to go.. ill have to get a thermometer and find out i suppose

Don't forget that there is a difference between ambient unexhausted heat, and heat produced locally on/inside the leaf due to photon bombardment, and that will expand the stomata as needed to absorb more CO2.. Raising temps alone isn't going to help, you need more light to process more CO2

that is phony baloney, imo


show me a plant thas grown in 70F-82F res temp conditions...


i can make a bet that plant didnt make it...and/or if it did....it had alot of problems and didnt yield much
