A few questions from a virgin grower

3) how do you stop light leaks from your intak fan

 No need for a intake Fan for a tent set up . A centrifugal will handle extraction and allow passive intake due to negative pressure .

 A good centrifugal fan is a must , but noise will always be a issue . 

  I just got a new 150mm westaflex I am happy with .  Its 3 speed and seems to move alot more air then my old can fan 150 rs

So you guys dont need and intake fan for fresh air.. I thought you had 2 fans... one for intake air, one for extraction

There is no need for a intake fan .

 You would use 1 centrifugal fan for extraction , the negative pressure created sucks air in through the path of lest resistance i.e side inlets or other ducting connected to your tent .

A tent sucks in on itself so any gaps or inlet will draw air and because of the negative pressure no smells escape .

ok thanks man...
