Northern lights

I am building a secret room in the back of my garage. It has one cement block wall and 2x4 insulated walls with vapor barrier and dry wall on the outside, 3/4 inch foam with silver foil backing and taped seams on the inside. It will be totally sealed and only one way in or out. the entry door will have seals around it. It will have it's own A/C unit so it wont mix air from the house or out side. I am growing northern lights. Do you think any one will smell it in the house or out side?

Yes. Sealed room are a myth Just get a carbon filter as well and you will be fine.

I have some ion filters

and Northenr lights is not stinky

northern lights will be fine, 1 of the best for indoor growing tbh they dont smell much but they smoke good

do you think you will be able to smell them outside the room

nah i doubt it, might smell a little but not noticeable

I grew NL about 6 months ago and towards the end of flowering I could smell it 30ft away from my house. Although my grow room was venting to and from the house anbd no odor control of nay kind

I just harvest N.l and the smell was not strong at all

it has a sweet smell to it imo , you will be fine , just make sure you have some filters if your that worried , but n.l is not a big smeller , but taste fucking good ,

my two northern lights plants are fully vegged and just went into a 12/12 cycle...smells fresh, but not stinky or skunky or even like bud. they will eventually but you got some time before you get the carbon filter, and yes, you'll need one.

I recently installed a carbon filter,and the smell has completely disappeared. I highly recommend it!
