Automation: Fresh air versus recirculated air
    #1130855 - 12/11/02 01:56 AM (13 years, 10 months ago)

My friend is still batting around ideas for his automated growing chamber. His big concern is in reguards to fresh air circulation. In his plans, he has a fan that will constantly circulate the air that is inside the growing chamber.

He also plans for a fan that brings in filtered air into the growing chamber that mises with the recirculated air.

His question is, how often should he run the fan that brings in fresh air. The timer that he is planning on using is only programmable in 30 minute intervals.

Also, when the fresh air intake would be running, it would bring the humidity in the chamber down into the mid to low seventies. (in theory of course) So, he would like to keep the fresh air intakes to a minimum in order to maintain humidity.

I know I have posted a similar question before, but not exactly the same, as he is trying to hammer out the details.

Thanks!  :smile:

I don't have TMC with me but I think it contains parameters about how many air exchanges per hour are needed for cubes - variable N (/h). The volume of your chamber is V (m3) and the fan pumps F (m3/h) of air.
x = (N * V) / F
For example: If you get x = 0.5 then the fan should be on 30 minutes per hour.
You'll have to take in account the static pressure of the filter when calculating the value of F.

Cubes don't need that much air - they grow even in bags with almost 0 air exchanges.
