Fan size for 5x5 with 650-800w led

Thinking about going up a tent size and wondering if the 6” fan is good enough for a 5x5 or if I’ll need to size up to 8” gonna probably go with a mars fce6500, volt fl1, or samphon 720 it’ll be a couple months till I can put it all together but if the roomies want to sell to friends a 4x4 ain’t gonna cut it

Go the 8”. Even if it’s slightly oversized you can run it on lower speeds for less noise and strain on the motor

Definitely go 8" & just run it slower.

How about those clip on 6" hurricane fans, should those be replaced after 1 year constant running?

I use an ac infinity clip on fan in my 4x4 probably get a second when I size up, at $50 a piece they better last more than a year though

Right now my exhaust is fan is one of those old big metal turbine looking things it’s a 6” and works, it’s just loud as hell carbon filters hooked up on the outside I half ass wonder is this 630de cmh is enough for a 5x5

Man I'll tell ya what, the AC Infinity inline with pro-controller is nice. Sits at a low speed until your temp or humidity gets high, then speeds up for you automatically. It's worth the admission price.

That grow looks great btw, holy smokes!

Thing about them old loud fans is they work and they work forever.

As to size.. depends on your external environment .

But yeah, better to have a bigger fan you can turn down ... have it and not need it rather than need it and not have it

I can tell you I can run a 4x8 with about 1200w of LED with just a 6" centrifugal extractor and its on a variac running 50-80%

But I live in mild UK
