Ill start off by saying we had a leak last winter and vissible roof damage down stairs. My mom was told it was an ice dam only at the door. but i personally think that we got some roof damage and its possible that there was alot of humidity sitting in the attic for a while could have caused some mold to start growing. i live in a condo and i dont think there is a vent up there... like shouldnt there be some sort of exhaust up there? i guess i could go up there but my lights are hooked up to it and it would be a bitch to take it apart and redo. i also dont know where the bathroom exaust leads too? hopefully outside and not the attic... if thats the case i prob have an existing duct system i can share with the bathroom fqan
I have to add some vent fans i think i may be best doing this only in the door (pretend the door is a wall... im a 19 year old medical patient still living with mom. she said no drilling through the wall, but i can buy my own door and drill holes in it) So i am definatly intaking from my bedroom which is on the other side of the door. should i exaust into the attic or exaust into my bedroom. if theres mold in the attic i dont want it coming down through the weaker fan because i also have a 435 cfm or someshit like that for my lights exausting up in to there. the ventilation fan is 160 cfm
Should i keep the light how it is and have the 6 inch 160 cfm fans like 1.5-2 ft apart on the same door? will they still work if i did that?
i know im not really set up but i have restrictions. im the only personm that smokes in my ouse and everyone else is like anti-weed
will the stronger cfm fan going up there make the 160cfm fan useless because its putting air up there at a faster rate?
my grow room is like 300 cubic ft with 1900 watts, 1600 is hps i cant turn my lights all the way to 100% without heat problems. so the 1000 watt is on 75% and the 600 is on 100%

I use cool tubes and exhust to another rooms.

2000w max to vent in another room so I think you are okay.

I intake from the grow room window and exhust to another rooms like I sayed.

Hope this helps.

How do you set up an intake through the window and keep the window insolatwd from the heat and cold in the summer and winter?

I dont need to isolate the window at all!!

I have this kind of window

Low-E-Glass-Sheet.jpg

Its standard in the EU to have such windowes.

Temps is great also when lights out.

But any way if you need to isolate urs you can use glass insulating sheet.

Hope this helps.

I don't have any Windows. It's a walkin closet. I have a attic door and the door to the closet which is adjacent to my bedroom. I have a window about about 20 ft away from that door but it's a crank and swings open, so I can't even put an ac in it.

Make a hole on the top of this closet to exhust your cooltube and work with passive intake.

I have done this before

Temps with 400w in cooltube reaches 26/27 with just passive intake

I dont use this closet any more but Ill give you an idea

So what your saying is intake my hood air from the door and also intake the rooms fresh air from that same door, which has my bedroom on the other side?
Not to pull anything back down from the attic for my light? My concern doing this is I have a wayyy stronger fan for my lights. I'm concerned if they are both blowing up into the same tiny attic air is gunna get pushed back down threw the 160cfm fan and actually make the exaust like an intake?
I really don't know how else to word my question. I just need to know the most efficient way to hook up the hoses to my pre existing holes. 2 in ceiling in the attic door and 2 in the bedroom door.
I'm worried that having so much air being pushed up the will create enough pressure to come down threw the week fan. Right now my lights are hooked up to the ceiling only exhausting and in taking to the same room.
I don't know if there like a vent up in the attic but I would assume there should be so humidity doesn't build up and shit. That's how it should have been built... Correct?

Yes, attics generally have vents. Either the peek of your roof has a gap, with roof caps, or there is a (maybe more than one) vents on the roof, or there are somekind of slats, or vents on the side of the house where the attic is to let air escape.

No its not if you used nice fan I would recommend the s&p silent.
Also push air through the cooltube

Filter fan cooltube out

I literly dont hear it outside the room.

So I don't need any more fans? Just leave on side of the light open and put a hole in the door? Isn't that going to be loud? I would have to leave it on all the time right?
I don't have a carbon filter either

Yah leave it on all the time. If you are worried about positive pressure in the attic blowing moldy air back into your grow space, I would seal up the attic and do some version of that picture above. Run your fan(s) through your light(s) and out the top hole. The suction of the air leaving pulls air through the filter in the bottom hole. :)

I'm going to try this out today. I'll try to get up there and look for a vent but it's not easy to access being directly above my plants.
Why do you push? I believe pulling is more efficient with the hoods I have. Pulling makes sure the air is smoothly traveling into the next hole/flange whatever they r called. If your pushing air towards one side of the hood there's no way to garuntee a smooth path UNLESS you have one of those tubes surrounding your bulbs, but I use the styles that have a swing down glass panel.

Is it important to make sure the intake is from the bottom? are those filters cheap and light proof? I have light on in the bedroom
