A 4 inch inline growing grade fan would work perfect. They typically run about 200 cfm. Computer fans do not respond well to pressure changes, I would not recommend them to anyone with more then a PC case grow.
Home Security? None cept my 40 lb pitbull/beagle mix. He clearly knows the difference between a good entrance and a bad one which he has demonstrated in the past. At the end of the day he is just to ward off the average theif; cowards.
Yeah I know the smell, and since I am relatively new to growing I thought I had a mold problem. All my plants have had this smell. The smell is completely gone in my cases after the 1st week of curing.
Just today I installed 4 new 15AMP breakers and ran the wires to my operation. 15AMP per thousand watt. 14 gauge wire is okay for a short distance, but I had to go 50 feet so I used 12/2.
If I had a 8x8x8 grow space and I put 4 x 1000 watt bulbs open hung vertical. What should my air exchange rate be? Air is being sucked in from the outside and exhausted outside. I was thinking 1000cfm would be enough?
My idea was to have 3x 6 inch in line fans pulling through each there own...
When ever I clean off my pre-filter tons of dust comes out. The inside of the carbon filter does not have a pre-filter, so you would be packing it with dust more then likely.
I am just referring to blowing through a carbon filter rather then sucking through.
I do not see why a well built box...
My buds are just entering jars aswell. Yeah they look damn good, but smelling like crap is an under statement LOL. I am on my second grow, and the smell clears up well.
What is the door made out of?

^ This style and size/power fan is what you would want.
Sounds like a situation where I would make a 4 inch outlet through a door or wall and cover it with a heater grate.
Then...
I rent a lower class house. It is on one of the worst streets in my not so bad city. It is a two story 2 apartment house. Each goes for 400. On the beginning of next month I will be renting both for 1000. I make sure to take care of yard and house work so the landlord never has a reason to come...
