Can someone explain the fan system that goes into the tent ?

[u1556]

I am looking at getting a small tent about 40x40x140cm.

This will hold about 100 W to 240 W of LED lightning.

So what fan Wattage I need for this ? ( Any recommendations on very quiet fans welcome (150mm) )

The fan will blow air inside the tent, right ?. So the fan + tent is the most bare fundamental I need right ?

You will need a fan to remove the hot air from the tent. It is also a good idea to have another fan inside the tent circulating air and blowing a nice, gentle breeze on the plants.

Yes! ^---- is correct. You want at least a 190 CFM inline fan. The fan will PULL the heat out of the room and passively bring in fresh air. Most people I know that grow in tents mount the fan on the inside of the tent with bungee cords. A fresh filter on the intake end, the other side, the one that blows air is ducted to the exhaust port. Keep in mind that you want it light tight. No light leaking in from the fan.
