Hello everyone, this is my first thread on this forum.
I recently aquired some Blueberry chessecake seeds (At least that was what I was told from my friend) and have decided to set up a small grow closet with three plants.
This is my growroom. The space is 0.56 cubic meters (19.9 cubic feet) and as in the image contain a power socket at the base. Water might be a big problem considering the placement of the socket but I intend to build some kind of protection around it to keep any water away.
The bar in the image has been used for cloth hangers until now, and this is where I will hang my lamps. The walls will be covered in Mylar, and my hygrometer will be placed on the back wall.
Now to the interesting part. At the base of the closet I will drill a hole where air can flow into the closet. Above the closet is a smaller cabinet near the roof where I will run the exhaust through and along the roof of the room through an 160mm airduct tube that will end out the window and be disguised as a heat pump.
In order to lead the air all the way out of the room the duct will have to be 5.5 meter in length. The fans I intend to use are 140mm PC fans with a CFM of 60. The RPM of the fan is listed at 900. I plan on putting one fan in each end of the air duct to suck air through it.
Now, I dont know much about airflow, but I imagine that as the length of the airduct increases, the fan will be less effective at moving air through, is this correct? If so, how do I know if my fans will be good enough for the job?
The reason why I picked PC fans to do the job is that they will mount perfectly at both ends of the air duct, and because I am on a (very)tight budget and can get the fans for free.
In my mind this should work well enough to grow three plants, but as I hate doing things less than optimal I thought I would ask before I do anything
