Intake, is outside air better or can it be to cold

[legalizeme]

I am going to be growing in an out building, which will not have any heating but will be insulated with 50mm kingspan.

I am debating where I should pull my air intake from

Am I better off using outside air or is the cold an issue?

[Dr Plough]

I intake from outdoors

[Dave-Hester]

I like to have a cold intake mate, helps keeps temps manageable.... Be sure to put something over the end of the intake to stop bugs or dust and shit getting blown into the groom.

Pair of cut up tights works a treat mate.

I need to decide on the best scenario

I have intake and out take to decide

Options are, have intake and out on same wall, one top and one bottom approx 1.5 m apart in height and 1.2m width away from each other

Or intake from outside and vent in other outhouse, but my concern is the heat my heat that room up as it is small and may cause the room to sweat.

Or intake from the other outhouse and exhaust outside

[Dr Plough]

What ever you decide make sure you intake at one end and extract from the other end so the intake gets oxygen and co2 to your plants before you extract it . Iv seen people put them next to each other lol they were basically extracting the good air

i intake air from indoors room temp,they luv it atb

[Anonymiss]

Temperature issues aside, air from an occupied room contains appreciably more carbon dioxide than air from outside

I intake from outdoors and use a temp controlled fan controller keeps temps bang on I did have to install a inline shutoff on a timer bc when lights were off cold air from intake source would come in. with watering system I can let it go for 5-6 days if need ever came. Not that I can stay away, I'm waiting outside the tent just before lights come on most the time lol

hey

can I get your advice. please see the attachment. my exhaust is going to go in the top left hand corner. probably a 6" Ruk

my grow room will finish approx. just past the half way point of where the window has been bricked.

I presume my lights are going to more central to the room and I would be ok to knock a couple of bricks out of where I have bricked the window up to exhaust out of.

Need a hole, make a hole. Just try to not make it plane as day that it's ur groom exhaust.
