Air Exchange?
    #3612289 - 01/11/05 01:26 PM (12 years, 3 months ago)

I found this picture in the archives just wondering which one is the best for air exchange. I apologize if this question has already been answered.

Thanks

IMO 2 or 4, probably 2 though

However if those are fans either one would probably lower rh significantly unless on a timer and there are easier ways then fans...like cool mist humidifiers or air pumps which will give you fresh slightly HUMIDIFIED air.

Number 1. will distrub the least amount of air. Acting like a regulator. (I would suggest that one.)

Number 2. will PUSH fresh air into the warmer/dry part of the chamber, and PUSH cold/moist/CO2 air out. (Would possibly make it dry inside, unless you recirculate.)

Number 3. will PUSH fresh air into the cold/humid/CO2 air and mix-up/dilute it, and PUSH warm/dry/mixed air out of the top. (Great if you recirculate!)

Number 4. will remove all moisture/CO2/cold, leaving hot/dry/non-CO2 air in the top.

If you don't intend to recirculate, then you better have a great humidity in your house! If you do recirculate 100%, then it does not matter, but 1. would be the best so that you don't disturb the mushrooms that much. (All the air inside will be diffused 100% after 5 min.)

These would only matter in places that have little circulation and the containers are 6 feet or taller. (Green houses) where it takes half a day to replace the air inside the container.

If you use a fish-tank pump, you want that on the bottom, and the exhaust will naturally be on the top (Container lid). If you use a moderate computer fan that is 22 Cubic feet per min. Then you will have replaced the air inside your container 11 times every minute, no matter where your holes are. (Aproximately)
