CO2 via Yeast The Right Way, With Calculations..

hay, thankz for that advice, would never have know that... well, i been plannin to rearange my setup for a bit and it's gonna be done within the next month.... take a peak at a few pics with my measurments and see if ya can give me some idea's to work with that, first pic is the present setup......

Thats hurting my eyes.. I've been drinking a bit, so intense focus isn't easy when your eyes suck to begin with.. I know how tedious it is to redo work like that on the pc, so I'll see if I can zoom in and harvest data when I'm more up to it.. Impressive planning from what I've gathered so far though..
Is the faint stuff important? Should I tinker with contrast etc to make that more readable, or is that erased/irrelevant??

Oh, and on the drinking bit, in the intended spirit of this thread, to quote Clancy Wiggam, "Theres nothing like moonshine from your own still.. "

lol, sorry man, wuz just my rough sketchs there, got the old one on pc already and gonna have the new one done for tomorow, so just wait and i'll send ya better pics, he he he....

Woohoo... Happy drunk guy..

lol, well, when ya get back, he he he, here's a better pic for ya...

Is this in the basement? How high does the air need to be pushed to escape the roof, and what kind of line does the ducting run in?
I just see you have 300/500cfm intake that won't be nearly as impeded as the filter and climb the 440 needs to combat.. The result would be positive pressure in the flower-room which would cause odour leakage.. Any specs on the 440 that may help estimate the actual cfm at that load??
Beautiful design overall! Worthy of a non diy CO2 system.. I'd put the thermo controls on secondary exhaust power, not intake.. I'd go nearly passive intake, moderate full time exhaust just to keep a slight negative pressure in the room, and then the 440 or better to kick in periodically and suck all the heat out.. Its hard to say without some rough experimental temperature numbers though.. Got any or is this drawing board at the moment?
In regards to the CO2, to increase your 440cuft volume by 1500ppm you'd need ~37g/complete_air_exchange CO2.. Actually only about 30g/complete_air_exchange since average norm is already ~300ppm.. So you need to know how long it would take for the temperature to rise.. You should probably put more power to the light venting, and perhaps connect them in parallel..
A fermentation will add CO2 no doubt, and you can produce alot of CO2 if you ferment alot, but everything else you got planned seems pretty tech.. Propane burner might be ideal.. Assuming complete combustion you get 3x the mass of propane burned in CO2, and can produce it pretty quick.. I don't know what it costs to bottle..

ya, it's in the basement, fake wall.... at present the air is just venting in an adjacent room, and all fresh air comes from a different room..... gotta wait for the good weather to come back so i cant get it venting outside......
the main fans for the exaust is presently a CanFan RS 6HO 440cfm for the carbon filter and a CanFan 6 250cfm for the lights...
when i get the piping out the roof, the main fan will be mounted 19 feet up in a direct line, only bend will be in the grow room itself, it will have a 5' length to push after that, thinkin of getting a CanFan RS 8HO at 722cfm for that purpose tho....
and as for the air flow, lol, already ripped out some of them inline intakes as i wuz rerouting my exaust lines, got good passive air flow now..... as for the temps.... i been battling with them, can't keep them lass then 94 2 hours after the present pair of 600w's come on, stay under room temp when the 400w is on tho....
hoping my new exaugst/intake line routing will do something bout those temps....

Alot of ppl with cooled lights are running 250cfm/light parallel.. Apparently it makes a ton of difference if you pump that..

im glad i found this. We just doubled our grow into two halves of the garage 22x22x~15 ceiling at about 7000 cbf. We're running it sealed, and the 22$ refill came around awfully quick getting that sucker filled up. I built my youtube fermentor thinking i could supplement our refills with some yeast action. haha, not at all. Good info, i think im going to follow your recipe to the book considering 0 air exchange and 320 sqf vegetive. I'm a bio major, and yeast budding life cycles and death are awefully interesting. props on crossing boundaries.

In an area like that, again I'd be thinking propane.. A 20lb propane tank yields almost 60lbs CO2, and in that area heat should be manageable..

ohh, ph balance the whole brew to around 4 correct? not just the initial mix

High 4's, I don't think 4.0.. But yea the whole mix..

i looked into the 600 dollar burners that produce something like 22,000 btu heat? we just got a movincool 10,000 btu air conditioner for dehumidification and additional cooling. We pay the utilities and id feel awefully fucking retarded having a 10 amp cooling draw on my meter while ive got a burner running along side it. also, we're maintaining a completely sealed room unless it gets too hot in the summer. 6000 watts in both rooms with shared air. is fermentation still an option? i blended some potatoes and whole grains and added it to the mix. and got a good bubbly going... with DI water the PH came out to be 4.4.

and no ones brought up aerobic co2 generation... how many hampsters would get me up to 1200 ppm?
?

This thread is a trip

Thanks for the info,very intelligent,very informative .

hey how long will this last and what do you do to keep it colinating or do you just start over when ?

rabbits 1 per 10 sq ft

Rabbits huh?? Could work.. And it would definately be a good odour mask..
When I say good, I mean effective btw.. Alot of rabbits are only slightly stinkier than alot of hogs I think.. The most ingenious idea I've employed was getting a place in what was for all intents and purposes, bakery central.. There were 3 right outside my window across the lot, and 2 more just slightly further upwind.. (Was only 1/4 mile away from Lake Superior, so convectional effects off the water made the wind very predictable)..

yeah, you said it man, i feel as if, no, hehehe ahahah! I'm relapsing RIGHT NOW WOW I'm TRIPPPING LOL did soME ShRooms The oTher day and ThEY are in my head again . . . lol.. . they were fukkKing good then , aANd I knew i'd have a relapse like this eventually i'm coming down... .slowly
wow
