diff of gas and air exchange
    #4429994 - 07/20/05 09:12 PM (11 years, 4 months ago)

i just read on a post that gas and air exchange is not the same thing. i know this but figured they would be together when you circulate.

how do you provide correct gas exchange and how much.

how do you provide correct air exchange



i i got a HEPA filter with a fan and ductwork on my setup, how would you provide this setup for correct air exchange as well. or is it getting good gas exzchange already ?

I'm guessing you know what both are and are just thinking about it too much.

Your setup sounds fine....definitely with air exchange. It could be a problem lets say, if you were in a sealed room that built up lots of CO2 and thus you would have good air exchange but not good gas exchange.

i figured so, i just read that on another post and wondered what they were talking about, i would assume that it would be the same unless you selaed the setup into an air tight closet or room or somehting like you said.

Gas exchange is the change in atmospheric values, it is directly related to gas buildup (CO2) in jars during incubation. It is imperative that this buildup does not occur for a healthy vegetative growth thus venting, it can be as easy as cracking the lid but we also have the holes (4) used in the PFTek, which most of you beginners should be learning by, allows for this.
Fresh air exchange (FAE) is in all actuality the lowering of atmospheric CO2 rather than the introduction of O2 (oxygen) :wink: , it is directly related to:
#1 the pinning process.
#2 the rate fruit bodies mature.
#3 control of pathogenic evasions (contams).
