so??? not under , in the shade , or at the top of your cab/room . pretty much right under your light? just currious.

whats your temp at canopy level?

85 degrees in flower with co2,but you could have fooled me by the readings the five wall thermometers gave spread around an 8 by 8 room.Point is,until I got a lazer thermometer I didnt have a clue as to actual canopy temps,I thought I was pretty close but I wasnt.I good investment for 100 bucks if you can swing it.
89-92 under 2k - sealed w/CO2, AC & dehum...and lots of ventilation.
i cant check, my thermometer maxes out at 27c and thats not even under the light!!! i would guess 30c or more lol

Sandman how can you use "sealed" co2" and "ventilation" all in the same sentence lol?I dont understand bro really are you somehow venting and replenishing or something?

Actually if you vent and replenish quick enough,it can be of value I've just never known anyone to do it because it takes a lot of special expensive caca to get that one together.I have a 80 cfm fart fan in the ceiling on a wallswitch timer to vent during dark hours only because between the pilot light and plants making co2 during dark hours,I'd be at 2500PPM when the lighjts come on.

80-87 F canopy tops, with co2
under the leaves it's probably 10 F degrees cooler.

Perhaps I should have said lots of air movement within the room. There's no in/out of air...but there's a couple of 16" oscillating fans moving the air around the plants.

I had the feelin,I just mounted an air king 18 inch wall mount oscillator this thing moves air!

My setup is a grow closet in a spare 2.5'd x 7.5'w x 8'h two passive intakes a foot off the floor, an intake and exhaust four feet off the floor and a carbon scrubber system exhausting out into the spare bedroom 12 inches from the ceiling. Got 5 plants under a 600w and 400w both air cooled/glass shielded with a 12,000 btu window A/C keeping the outer room cool to act as an exchanger for the closet grow. Temps at canopy level are at 80F. Lights are about 18" from growth tips. Whole setup acts as a closed system and could use co2 but I office in the spare bedroom and it wouldn't be too healthy for me. Plants would love it though. Open vents on A/C keep ambient co2 at natural levels for me. Only growing for myself and that's good enough yield to please me.

Wouldnt be too healthy for you?You have algore syndrome bro and thats an inconvenient truth lol.Co2 in NOT a poison,though a lot of people with an agenda would like you to think as much.I guarantee if you sit in an 8 by 8 room for 15 minutes or longer the co2 level will rise to around 1000PPM,you exhaling it constantly.When you get to levels about 5000PPM,and you are exposed for a length of time,then you may have a problem.I spend six hours sometimes in an 8 by 8 room at 2000PPM plus all the damn time,people take the danger way too seriously.EDIT Its easy to test for yourself the testers are 5 bucks at the hydro store,you and your sig other or yourself as in my case slleep with the door closed one night and take a co2 reading when you awake,you going to be surprised

Don't intend to get into it with you ballastman but I will tell you this. The body was intended to get rid of co2 through expiration in order to keep the pH of extracellular fluids at 7.35-7.45. If the alveolar pressure of co2 inside the lungs is greater than that inside the blood (and it is when it's at the levels used for our grows), then co2 exchange is compromised and the body builds it up. To put it in terms you as a grower may understand, supply your plants with 4 times the o2 without supplying them with an increase in co2 and see what happens, lol. You will in essence be cutting their available co2 to 25% of what it is naturally and they'll not be able to carry out photosynthesis.
No need to talk down to me. My politics are so conservative it would scare you and I could find no use for anything Bill or Al had to say. And Clinton didn't even inhale, hehe. Al Gore and Clinton were trying to make a case for greenhouse gasses which are at a much lower ambient level than what you we are speaking of with regards to supplemental co2 for our plants. If the atmosphere we breath changed over night to the co2 levels we use for supplemental co2 for our plants, life here on Earth, as we know it, would come to a halt.
My statements aren't based on the political spewings of people paid to promote an agenda. My statements are based on human physiology, in particular studies done on the effects of respiratory air exchange and its relationship to PO2 and PCO2. Respiratory acidosis and alkylosis is something I see every day in COPD (Chronic Obstructive Pulmonary Disease) patients in the respiratory therapy unit of the hospital. Your body will compensate up to a certain point by increased kidney production of HCO3 (or bicarbonate), but do you really want it to have to? And I said "up to a certain point."
I'm not promoting an agenda and you're doing what you're accusing me of doing. You're repeating what you've heard others say without learning if it's fact or not. You're free to believe as you will. We both are, to our last breaths, lol. If you've read any of my other postings you know this about me, I freely admit my ignorance when it comes to things I don't know about or am learning about, such as growing. And I'll let those who know more than me educate me. But when I make a statement that is based on fact and proven science and I'm laughed at and accused of having an agenda, I will then attempt to educate others who are ignorant of what I'm educated in. You're probably a nice guy, as I haven't met you, I can only assume. I'm a nice guy also. Let's try to get along and I promise not to laugh at you about those things that you know more than I. Would appreciate the same from you. Here are some links for you to read if you'd like. I try to learn every day and some days I'm more successful at it than other days, lol.
Peace
PM me if you feel like you'd like to respond, don't need to tie up the thread. Sorry all for the inconvenience. Got called what could basically be termed "an uneducated, politically influenced, easily duped, promoter of false information" in so many words, and felt I needed to respond.
Just found this one, it's actually a pretty good primer for the physiology of the respiratory system and how it carries out gas exchange.

In this one, scroll about halfway down to the part that says "Pollution and toxicity" and look at the second paragraph.

Repeating what I've heard?I just told you man I spend hours and hours in an atmosphere of 2000PPM or more,I do this twice a week and have done it for 6 years.Its nothing I read man I thought I made that clear.Sorry if you got offended by my algore joke,thats all it was anyway.I want people not to be scared for nothing thats all.all that gobbledigook you posted is interesting,if you have a PHd I guess but nothing beats experience and I experience it twice a week.I just dont want people scared off co2 for no reason,thats all.
