What lights & what ambient temperatures will you have?
It's Not What You Know, It's What You Can Prove
Thinking about mars hydro 1000
Amb temp around 19 degrees
I consider vivd aswell but i'm asking about ventilation system in this thread. Need to know what do i need in my setup - i need to know if i can afford.
Which fan and filter do i need to be enough to neutralize smell
I'm not really an LED guy but I would have though the best option would be a 5" RVK/Rhino with a fan controller... others using LEDs may have better thoughts?
4" fan/filter should be plenty.

To work out your extraction multiply all the sides of your tent together to see the amount of air it holds ...
0.7 x 0.7 x 1.6 = 0.784m3
So your tent holds 0.784m3 of air. You want to replace all that air in the tent multiple times per hour so to work it into m3/h we multiply by 60minutes (1 hour)
0.784m3 x 60 = 47.04m3/h (total amount of air over 1 hour if the air in the tent is exchanged completely every minute.)
I generally recommend exchanging the air at least twice per minute to maintain negative air pressure in the tent. This stops air flowing back out of the tent before it can be filtered, so we can double that number
47.04 x 2 = 94.08m3/h.
Adding a carbon filter generally reduces the fans effectiveness so we allow an extra 50% to compensate.
94.08 m3/h x 1.5 = 141.12m3/h
So what ever fan you buy needs to be rated to at least 141.12m3/h. You want to go with one bigger than this ideally and slow it down with a speed controller. Bigger fans running slow are quieter than smaller fans running fast.
Any bends in your ducting will reduce effectiveness too and generally 20% is added for each 90 degrees bend. This will vary depending on your set up so if you do have any bends then multiply by 1.2 for each 90 degree bend you have
NO SELL, NO SMELL, NO TELL!!!
