I just built a growroom and had a couple questions about airflow. Is there a way to measure,check the amount of oxogen that is going into the room to make sure it is appropiate for fruiting?
Personally I would like to make sure its positively presurized and still maintains pretty good humidity levels.
Also are there meters or something that show you the oxogen and co2 levels in a room? What are the best O and CO2 levels for fruiting btw...
thanks

Hey b n t.
IMO, establishing the proper environmental growth parameters within the fruiting chamber is a balancing act of sorts. One must provide proper fresh air levels while maintaining constant temperature and humidity without overtaxing heating and humidification systems.
One can accomplish this by the use of a mixing box which contains a damper allowing one to regulate the volume of outside air introduced relative to the volume of inside air recirculated.
Stamet's and Chilton's "The Mushroom Cultivator" contains some outstanding information on this subject. The book details growth parameters for a variety of fungi, in varying stages of development, including number of air exchanges, and CO2 ppm (albiet worthless to me without a meter) etc. I suggest you pick up a copy if you don't already have one.
There are meters which measure the amounts of CO2 and O2, but to my knowledge they are pricey. Experience is a great teacher however, and together with above mentioned reading will give one a good idea as to what proper conditions are. There are a plethora of variables to be addressed including, but not limited to, the cubic footage of the room, output of air system, type/output of heating and humidification systems and species of mushroom. However, it's not all that difficult to one that is so inclined. Listen to the shrooms.

I wouldnt get to high complex about the whole thing "it is a science and know" but to get the results you want, you really dont have to be so perfect "not that its a bad thing".
As long as your keeping your humidity high And giving good air exchange(this could be fanning,coolmist,ultra sonic,whatever)yu should be in good shape. |

Hey Hiroller,
I am glad you replied, I got the ideas for my room from the pics in the archive of yours. Now that I mentioned it, what is that mirror on your walls? I am currently using a reflextive insulator material, but its (not a mirror if you understand what i am talking about).
To ask you a couple questions:
ahh shiiit it might be a few now that i know your answering..
how do you run your cycles, I read from your posts that you keep 3 humids going at once, i more or less want to do that same thing, keep the humdies and input fan going all the time, and the lights on a timer.
Also from that brazilian pic, how do you sterylize all that casing and subtrate all at once to get that "cycle of flushes" that i saw?
one huge oven??
hmm, for now thats all I can think about, thanks for answering..
btw i am getting myself the staments book for xmas, I feel that I am a pretty experience grower but am very thankful for your input. Ha with that flush i saw on the pics, your about my idol.}}
what is this...

Much agreed nilla. Like I said experience is a great teacher. Didn't mean to come off all technical and stuff. I mean, we're talking about growing fungi right? A good read and green thumb(?) will go a long way. Actually what I propose is not all that difficult. Wait, I already said that..... |

Hey bil, oh yeah, and ted. Are both of you really there? 
To my knowledge there were no reflective surfaces pictured. Hmmmmmmm........... perhaps you're thinking of another post.
Air supply runs 24/7. Just adjusted through the damper to provide proper conditions. Three humidifiers run 24/7. Same deal as the air, hence the balancing act. Lights on a timer 12/12 sounds sufficient too.
As far as the substrate and casing go, that does sound like a lot of work doesn't it? I've heard of guys using baking tins to do large amounts of dung for substrate and casing material in the oven. Large stock pots can be used to pasteurize good quantities of straw for substrate on the stovetop.
btw, enjoy TMC. Listen to the shroom.

"we're the wild stalions..." Yeah both of us are here.
Well the room seems good for now, thanks for the help.
