co2 enrichment in a 17x15x7 sealed room

i have a flowering room with approximately 3600 watts HPS lighting. i have a controller, regulator and tanks, everything i need for co2 enrichment. i have my nutes schedule locked down as well as humidity (45%). my question is: what temps will i need run to get results with the system i have described?

from experience only please, for i have read 4 books, and numerous articles online on co2 growing and i would like to to hear from some people that actually use co2 and have seen results, or from people who haven't seen results.

from what ive read seems like 90-95F is the best temps for the plants with 1500ppm max and a 1300ppm drop off point. i plan on enriching my vegging room as well, which is 12x14x7, i am unaware of the ppm levels that vegging plants need, but im assuming its around 1000-1200 ppm. my controller will control both rooms ppms separately.

I'm having good results at 85f/1250-1500 ppms, this is my first run with it setup correctly, my clones 'popped' and started taking off in a matter of 4 days, they're still in veg I can't tell you flowering results for another couple months, I just finished my tables couple weeks ago, so I'll compare and share when the time comes, I'm interested as well the flowering results of co2 enrichment.. What kind of controllers are you using, never heard of one that can control co2 in both rooms, your rooms are large why did you go with a tank and regulator, you'll be going thru tanks every other day, a burner would of been more efficient for you I think? 90-95f seems too high.. You could get away with it, I just don't like being that hot in there, 85 is still pretty damn hot especially if your grow room is in your home..

78 deg is considered the best temp for a sealed room, a/c CO2 set up @ regulated 1500ppm. 45% is slightly high rh, 40% being optimum. 1.7g/w @ those figures with Nirvana White Rhino, 40l undercurrent rdwc & full AN nute line with 4 x 1,000W in an 8x8 sealed room, 12,000btu ac unit. Monster buds! W

this is my controller, works like a fucking charm.. tons of controllable settings for night time enrichment as well as logs that track how often it has to turn on and off and the highs and lows of a 24 period/photoperiod

75 degrees huh? that contradicts everything that ive read, but i wont discredit it. do you have any pictures of your grow or a journal?

Yeah I don't think so, higher temperatures and low humidity is what I've always thought. Thats a sick controller, some bucks though! I've been using cap controllers, not too happy not as adjustable as new ones on the market. My ppm-1 costs $539, then saw one online called the ppm1500, it keeps your levels exact and it was $250. So nice to see equipment come down in price. I just ordered a tds/ec meter for $35. Sweet! Anyway about the co2, I've read the same things you have and I'm almost positive higher temps are recommended, anyone chime in with exp?

did some talking with the local hydro store owner, been growing for 10+ years, he keeps his room at 83-85 and co2 ppm at 1100-1300. he says that if you bring your co2 up to 1500 your plants can thrive at 100F but results will b the same from lower ppm levels and lower temps... i guess that the plant cannot use the entire 1500 ppms efficiently without higher temps, more perspiration. and yes this controller is fucking awesome and dead on.. i was shocked to find out that my grow room co2 were already at 780 ppm!

780 is pretty high, take it outside and see what it reads. If its over 450 you should re-calibrate it.

Ppm levels are correct, no need for recalibration. Put the sensor I'm my air cooled hood with air pumping in from outdoors, conclusion was that the air in my basement has natural ppm of 780 and outside air had ppm of 380

that makes sense, basements don't breathe much, co2 builds up easy..

I have run at 85-90 and just found it too difficult to manage the humidity. for me there seems to be a sweet spot that all of my equipment runs in perfect harmony. It depends a great deal on the ambient temps. In the heat of the summer, it's best to run my water cooled lights cooler, my temps around 78-80 which will draw the humidity into the 40's with little help from the dehumidifier(which will ad heat). In the winter, I have to run my lights hotter to create enough heat in the room, it will run nice at 82-85 with much of the heat and most of the humidity controlled by a dehumidifier.

I almost always run at 1500 but change my deadband. When they're just put into the box, I run 700-1500 and slowly raise it to 1200-1500.

For me, excessive humidity in a sealed environment with co2 is much more destructive than too high or low of temps.

A combination of the two can take you out fast!

Ye So that controller is a piece of trash, they r sending me a new one, it was 4 days ago they told me they would send me a new one over night. I've spent around 1500 on co2 equipment and now it cant even b utilized for atleast tues day because of July 4th.. such a fucking let down... My issue was the ppm meter kept going on the fritz saying my ppms were at 151 when my lights were off, no exhaust, and no co2 being released.. tried to cqlibrate the damn thing and it wouldn't even show any ppms, just say co2 calibration failed.

Bummer, that makes me doubt that peice of equipment, too many things and sensors going on. You should just return it and get 2 cap xgc-1e controllers. It'll cost maybe $200 more but you'll have a controller that has been proven.

If that is the case you need a little more ventilation in your home.
I'm intersted in seeing how bad the buds are going to stretch and become airy at the higher temps. There are other factors to consider like offgassing at higher temps etc.
I'll keep litening here...

You're suggesting buds become 'airy' and stretch more during higher temps? If so in your opinion whats the perfect balance with co2 and without (temp, humidity, ppm)(temp, humidity)

just my thoughts but you would save alot of money if you switched over to a co2 burner, I was using a tank like every week running at 1500 ppm and so I decided to switch to burners in all my rooms and now I get at least 25 days outta a 20lb propane tank and its alot cheaper and have found that between 83-86 degrees works best when using co2 in a sealed room

Things are happier in my grow room at 78f, that is all I can say from experience. I have read all the 'fluff' talk about higher temps, and it makes perfect sense until I consider other factors...
It is a known fact that the higher the temps the looser the bud, brother. I am quality freak...

co2 burner would be a good idea, but i have 2 50lb tanks for flowering and a 20 lb tank for veg. and the way my controller is set up it really is efficient.

my sealed room is 17x15x7 my regulator is set at 15 sfch and runs for a total of 1:08-1:20 mins, shuts off for 15 minutes and the cycle repeats. ppms never go over 1300-1500. im going to drop the temps tonight, hopefully my new controller arrives today

Temps usually around 85 degrees

so 85 degrees it is! what nute line are you using? ive been using fox farms whole system, and just started mixing that with roots organic new line and their additives

Well, you are making my point, look at how they are fox tailing out on you, that is a high temp issue. Nothing wrong with that, when I want to make hash etc. but for my personal stash of smoke I shoot for tight nugs bro. You need to show me a close up of one of those colas dry, if you want to impress me with a donkey dick. I have grown my own share of them, outside looks ok, but as soon as you dig in to the cola, they are loose, bright green and overall not satisfying to my taste. To each their own Max, I just wish you wouldn’t act as if 85f is common practice if you want top of the line dank!
To the op, once you have grown your first batch at 85f, and you see firsthand what I am talking about, just remember that all you have to do is drop the temps, to make it all better
Good luck bro!
