Hey guys sorry had a little question on this topic so thought I'd jump on...
Do you need to have an intake fan? Is it important? I mean I wont over strain my outtake fan or anything will it?

Intake fans arnt needed pal ,passive intake works fine ,so long as temps and Rh are in check then it’s fine
If you need more flow, adding an inlet fan is one solution. It works in series with the extract in a push pull arrangement
The need for a fan controller increases however, to ensure a vacuum is maintained

I use a 6" RVK L1 split 3 ways and get negative pressure in all 3 tents, 1.5x1.5x2.0 - 900x900x1800 - 900x900x600 and 2 4" RVK's for inlets. I have inlets on cheap £6 speed controllers to give the small tweaks both connected to Inkbird temp controllers. Have 28° in 1.5m tent, 27° in 900x900 and 22° in 900x600
Am thinking about an Evo or SMS controller but not just yet
I've never had an intake fan. I think the rule of thumb is your passive intake hole needs to be around of 2 x the size of your outtake, I tend to go a little bit more maybe 3 x and I always have the outtake on a minimum of 50% tickover.
TO GROW A PLANT YOU NEED TO THINK LIKE A PLANT
I don't use inlet fans whatsoever
Think of an inlet fan as a booster. It's like having a short duct run when it could be very long.
Bear in mind though, the flow of the system will never exceed the flow of the the most restrictive component

Very true ched but that can limit the flow of the big fan quite a bit I found. Sucking 6 inches through 4 inches or 8 through 6
With led mukka you won't need full pelt ever
