I really would love to hear some suggestions before I am going to scratch a hole in my bedroom roof.
Growing space/closet: (90cm X 50cm X 160cm / 3′ X 1.7′ X 5.2′)
Exhaust fan: 120 CFM, 10cm / 4′′ inside the plastic pipe
Plastic straight pipe 10cm / 4′′ ( 1M / 3,2′′ long ) goes directly from closet to loft. The exhaust fan is in the loft.
Lights: 270W Warm White CFLs, but the next one is 250W HPS
Using a fan controller
Questions:
1. If that kind of setup, then is it quiet?
1.1. I don't want to use bigger plastic pipe because want to hide this which goes out from closet ... a big teddy bear will be going to help the pipe.
1.2. Does it help/makes quieter if I am going to use a bigger and acoustic insulated ducting just in my closet or no point for that?
2. If I am going to use 250W HPS on my next grow, then is this setup/exhaust ok?
3. Is it ok to use 250W HPS if I have that kind of small closet?
