ya man, well first of all plant metabolism significantly slows down past 85 degrees, and pretty much stops around the low 90s without co2 supplementation, as has been discussed here.
optimal temps with co2 are probably between 85-93 degrees with 1500ppm, not much higher than that. growing at those temps without it is gonna get ya nowhere fast.

Same claim could be said about humans, but I know I'm more productive well below 100°F..

has anyone ever messured the c02 from the yeast/sugar method ? does it work ?

You can calculate the total evolved over a total period, but it won't be a steady rate.. By anaerobic fermentation you will produce roughly 1/2 the initial sugar mass to CO2.. By aerobic reproductive yeast respiration you can yield roughly 1.5x the initial sugar mass in CO2..
Stability of the rate this happens will vary depending on your recipe, and skill as a brewer, but there is no way to keep an actual steady rate without a few batches stagger started each day on a continuous cycle unless you were to contain it and release a given amount on schedule.. Which would be very impressive..

I too recently added a bottle to my incubator.. Looking to pic up a bad ass sentinel but I'm working with digital timers in the mean time; and Co2 calculator. I was wondering about night cycle and running Co2 at night, are there any special adjustments for the night cycle. I'm also having trouble keeping my Temp above 80. It's at a steady 76 right now..my grow cube is 3.5'x2'x1.5'... Also I added a humidifier but I can get it above 40%. It's steady around 28-30%.. It's my first grow so sum in put would be appreciated... I'm running 4 LGM5's panels fullspectrum LEDs with two 24w CFLS for side light... Procyon shouldcbe arriving soon...I didn't think the LGM's would hang but my too girls look healthy in there 3rd week of veg.. Ibwill try to add some pics.

Don't use it at night period.. And I hate to say it, but CO2 is a big-boy game.. Without HID its pointless! LEDs are great if you want to know when your drill is done charging, or you want a flashlight in your hat, but not for much more than that..

Thx fellas appeciate the input... Might have too stop kidding myself and go to the hydroshop to pick up some HID's.

Inval I got the liquid cooled hydrogen burner too and love it. I went vert two days ago and now the room is at 93 degrees and need to shut off exaust from temp controller to a timed interval as I chatted with flo jo about. I have a fifty gallon res and it was fuckn boiling last night so I put my ppm3 on a 1on 4 off nft to slow down the consumption of gas and give my burner a rest. With that said flow on max and gas on mid i only achieved 880 ppm with that setup. Tonight I plan on putting the exaust and fresh air on for fifteen minutes every hour. Need to get the chiller for the tank or do run to waste. How much was that valve thing for doing run to waste on the hydrogen?? Anyway penny for all your thoughts here. I'll get some pics posted one of these days. Gotta get out the ten foot latter though cause these bitches are big. Doing a tree grow like the great heath robinson except with 2 kw hps and 1 kw mh rolling the skunk strain. I'm running autopots here and dont have the run to waste problem eb and flow growers have should I still worry about keep the tank at sixty 8????

I was reading on HARVEST MASTER http://harvest-master.com/casestudies.html ABOUT short days and cycles with co2. Has anyone else attempted this?

18 hr Short Day Cycles: Fast Flowering
Through meeting store owners who are selling our Harvest Master controllers into the field, hearing directly from them and end users what benefits they are achieving, we monitor what we can do next, or what we can do to help.
Best story of all is from a guy thinking just slightly outside the square.
He is getting crop rotations in 7.5 weeks (down from 16weeks) ! (see more below!)
In the following case, nothing needed changing (except perhaps the mindset of the growers in the audience.
Getting an efficient output for the input used is what it is all about.
"Hmmm, says Harvest Master!". I have to be at least a little dubious. But,....
Try his thoughts for size. I have to think that there is something in what he says.

His assertion: ALL species of plant, insect or animal on earth have their "Day period" during which, their efficiency is greater for SOME of that time.
While they can use up to 18hrs of light, maybe for 12 of those, they are at 100%, then drift off to only 60%-70%, then to 20%-30%".

Consider,......
....most days I wake up and am at 90% in 5 minutes, at 100% in 10 minutes.
After 10/12 hrs, I'm flagging badly and while I am happy to stay up another 6-8 hrs, am just "laidback".
My young boy on the other hand, is at 90% within 10 seconds of waking and 100% in 30 seconds. He hits the wall "like a bird flying into plate glass" after 14 hrs, then sleeps like a brick for 10!!
Others however, take an hour to get to 60%, another hour to get to 90%!
Most animals use the time that they are given, to produce the best effect they can achieve with that time.

Plants don’t think, they react to a genetic 'drive to survive'. So, I conclude that there is a case to examine where a short day cycle could trip a plant's genetic response into a "survive or die" accelerated mode to flowering and fruiting.
"He wanted to capture the hours that would give him 90% or better, of the plant's "production" but maybe saving 25-30% of the daylight period" (power being a special consideration).
- He set his vegetative cycle at 14hrs day and 4hrs night for an 18hr day
- Ran it for 7 days (about 10 "plant days") at 2000ppm CO2
- That period gave him sufficient leaf development to proceed with the flowering phase.
- The "Fast Flower" 6hr days and 12hr nights regime lasted 45 days.
- His crop. "It is better than I EVER had in 16 weeks." Yields?, "I’d say 135-140% of my previous best crops.
- "It is so reliable I can set the crop harvest date into my wall planner on day one!" 7weeks and 3 days Harvest. Impressive result. 6 great crops a year, low management of them, every one a winner!
Well, being at least a bit dubious, I thought around the edges and finally concluded that a power usage analysis for the lights ON time per day, per month would be a gauge to the accuracy of the story and maybe prove or disprove it.
My analysis
The claims Leaf phase (light hrs) Flowering phase Total
1. Non CO2 4wks (28days @18hrs) ,12wks (84days @12 hrs) =16wks (1512hrs)
OK but 33% crop failures. 378 lights ON hrs/mth.
2. "Short Cycle" 7day (10cycle@14hr), 45day (60days @6 hrs) =7.4wks (500hrs)
Unbelievable result!
Easy harvest and growth. 250 lights ON hrs/mth.
Great result, especially that the grow room/crop management is also massively reduced.
3. Std CO2 cycle: 2wks (14days @18hrs), 10wks (70days @12 hrs) =12wks (1092hrs)
Fantastic crop. 364 lights ON hrs/mth.
Easy harvest.
Supporting evidence.
Indicated power usage for the short phase growing cycle reduces to about 250hrs/mth, from 378hrs/mth, a drop of 33%!.
The grower was a little concerned that in the early period of growing, power accounts were low. He thought there was underestimating of the power meter and was concerned to get a huge "top up" account. The facts were that his power usage dropped to 66%, a saving of 34% (from $500/mth to around $328/mth).
This had a consequential (side) effect of reducing residual heat in the room, nutrient and water tanks, with profound effects reducing mould and fungus problems.
These figures just blow me away. More than we ever envisaged, we have a customer succeeding with crops in a way he could never achieve before.
His total "light ON" period of 500hrs to get a harvest is amazing.
That is only 2/3rds of the time and 50% of power that a regular CO2 equipped growing operation is using.
In just 1/2 of the time at 1/3rd of the power, he has a better harvest than ever achieved with a 16week method.

We should let this guy loose on the government budget!
For the flower seeds he is cropping, he has hit a crop rotation and growing efficiency that would make most people's eyes water.

Harvest Master will also work great in these hot areas, controlling Temp and Humidity, and CO2. Remember, High Humidity is your friend providing; Harvest Master balances that Humidity with High Temperature and High CO2. Humidity HAS to be up around 70-75%RH at 30-32C/88-90F). With temp and humidity up there, and CO2 at 1800ppm, you could have growth at 100% extra over 74F conditions, and the plants will love you for it! Get humidifiers AND dehumidifiers in your room. They are cheap ways to get high growth and maximum yields!

Why is the math always so fishy?? How does a 25% reduction in day period equate to more than a 50% reduction in total period?? And I'm not even addressing the yield claims..
I am aware that plants can't necessarily use 12hrs+ of intense light as effectively as they could at their peak point during the day, but I'm still gonna call shenanigans..

A ya temps are better measured when your digital sensor is shaded. Like the directions say to do. Save yourself some grey hair do it. Mylar and one piece of duct tape and she's humm'n 330000 lumens 9 inches from the colas at 1500 ppm with 22 days left colas getting bulky. We have it really good here as we on pay a 1 dollar per gallon of propane.

I run 85 degrees with my CO2 at 1500PPM. Too hot and the plants will run. Too cold and the growth rate will slow.
85 is just right...
