Roof snow melting!

No snow on roof is typically a big red flag especially in areas (regions) where indoor grows are endemic.

ya if you ask me... winter time.. a root that doesnt have snow on it while everyone
else around them DOES = RED FLAG.

Just think about it .. use common sense.

If you noticed, im sure others will notice, you didnt notice just because you
thought about looking on your roof, im sure you noticed when you saw you
had a nice large melted area on your roof where as noone else does lol

Good luck man... grow in the basement lol Or make a room within a room so
its insulated from your home's outer walls.

I think that growing in a rented house is fraught with risks. Landlord shows up and wants to look around and bam! Busted. You need a stealthy operation when you are renting.

Just sayin'...

too bad you aren't in my state, northern most state in the stuck together 48 and yet we have no snow, we get like 3 inches every 3 weeks and it melts in 3 days, this years like a record, were all gonna die from solar flares or something...

id say insulate the hell out of your attic if headroom isn't an issue, but i wonder what your landlord would think about a triple thick layer of pink panther...
 
Well, worst comes to worst, the landlord HAS to give us 48 hours notice to enter (24 hours if it's an emergency) where I live so we could always tear it down.

The attic is finished.

Right now, we intake through the only window so I'll try to funnel the outtake somewhere downstairs. Might be difficult.

Posted on another thread and people seemed to find the watering the neighbours roofs pretty amusing. I think it's not an overly terrible idea... We have a big back balcony that would give us good access/range.

Will definitely insulate the room and see how that goes. Will report back later but in the meantime, anymore suggestions would be awesome. Thanks!
 
the melted snow will just tell them to look harder. i.e. take out the flir and scan ur house for anything out of the ordinary before they search. like the hotspot of ur exaust only hittin 1 spot and heating that spot while the rest of the attic is cooler even though the snow is melted on the entire roof. exaust into a chiminey or furnace exaust where heat is suposed to be comming from.


This is actually a good idea that I have thought of before (venting through the chimney). The only problems are that the landlord knows the chimney isn't functional... and also, I feel if the landlord were to catch wind, he would be extremely forgiving as long as we didn't fuck up his place (including making a hole in his wall to the chimney). I've had beers with him a few times and he seems reasonable so keeping him on my side is a big deal.

I guess the main thing I wanna confirm is that the cops can't get a warrant simply from the lack of snow. They would likely have to come talk to us or investigate more which hopefully would give us some buffer time to tear it all down and destroy evidence.

Just about to flip the lights so the next two months will be extremely stressful. Thanks for the help though gentleman (and women perhaps)!

What he said. I saw some canadian policebrochures describing your problem with the snow.

Hosing your neighbors isn't very neighborly and could bring about unwanted attention. I'd be pretty pissed if I woke up to my neighbor hosing my house down and would probably find it very odd.

Does your attic have a gable? If it does, throw a fan on it to make it an active exhaust. Passive, fresh air intake and an exhaust fan that runs whenever the lights are on to supply an unlimited amount of CO2, while cooling the room.

Why couldnt you intake and exhaust thru the same window? One elbow up = exhaust and one elbow down = intake.

snook...winter time air is often TOO cold to be blowing directly into a room that is supposed to be balanced...and is often 75+ degrees. This can cause unwanted humidity and moisture build up not to mention the plants don't grow well in the face of drastic extremes like that.

Your best suggestion was insulate it better...or if you must, room inside a room. I used to grow in rented space and it was the only practical option. I could punch holes in my "room" and never had to worry about damaging from watering or other such accidents that DO happen...

i learned this a long time ago about attic grows in the winter

imagine what hat would like like on flir .....

if you scrub the air well enough recycle it in the house proper and lower your heat bill or diffuse it through a room in the house and then send it out a window

What about all the extra humidity in the winter doing that? Won't the windows have lots of condensation and start to cause water damage elsewhere?
 
Should have been prepped in the first place if you ask me lol

But sometimes I understand, gotta do what you gotta do lol.

I had a buddy that grow in a straight up OPEN ASS ROOM with NOTHING
but LIGHTS and a FAN.. grew 30 plants in 5 gallon buckets.. YA THEY GOT BIG lol...
he was strapped for cash so he had to do it. Did it.. clean it.. and now its
done with and you'd never notice. :-D


If your gonna do ANYTHING always make sure you dont make the exterior
walls of your home WARM... that is how FLIR is used to fuck you over.
If a room within a room is 100 degree and your exterior walls are same temp as
the outside air.. that 100 degree room WILL NEVER be seen on FLIR..
It isn't XRAY.. its technically on the opposite side of the waves spectrum compared
to XRAY.



Depending on your location, you should be able to judge how important it might
be for you to address the MELTING ROOF... if your in the middle of a neighborhood with newer homes.. then id say big red flag.
If your in a rural area, with older homes... it could just pass as a bad insulated home.
:-D Only you can determine how comfy you want to feel :-D

Do you like piece of mind? I LOVE IT hehe
 
if u have a chimney and it is not in use theres a pre-existing hole in it sumplace in ur place from when it was in use. like a wood burning stove or sumthing that used to be used as a heat source. look around the chimney (if they did a shity job) for a plastered/coverup of the old hole. alot of old houses just have a metal plate looking thing stuck in the hole to seal it off.
the second would be to put a Y spliter on ur furnace exaust if u have access to it. if you think your landlord would be fine with you cutting out a 1-3 foot section of the furnace exaust ducting and add the spliter that can be capped off when u move without causing damage to the rest of the house or having to cut holes in the walls or floors.
if those options arent available i would see how reasonable ur landlord is and ask him what he would prefer u to do. its will most likley be cheaper on u to let him know that u are goin to cut a hole or sumthing then for him to find out on his own and u get a lawsuit for damaging his property if he wants to be a dick. then u would have to explain in a court room why u had to cut exaust holes... thats alot of un-needed attention from the wrong group of people(officials).

pray for no snow and best of luck to you and figuring it out.

How about this, take the hole where you vent into the attic, run a long length of ducting in a loop in the attic then reconnect it to the same room. So the air goes into the duct loop on one end hot, gets cooled by the cold ass attic then comes back in in another port cooled.

No direct blast of hot air to the attic so it shouldn't melt the snow, shouldnt raise the temp any more than a normal heating duct would.

that wouldnt be a bad idea if its a small room and a small fan. if he is running a fan with a high cfm it will sound like he has a jet engine running in his attic. also if the attic isnt cool enough to cool the air in the duct his grow will just cook the plants and the duct will heat the attic like the exaust is doing already. also i think a 20 foot glowing anaconda in his attic would be suspicious on a flir. good idea if its hooked to a duct cooler close to the exaust of the grow.

Flir doesnt look thru walls, it would look no different from the outside to FLIR then a normal heating duct run thu the attic would but you wouldnt even see it on FLIR cam. FLIR doesnt see ducts from the outside.

Plus what's more of a worry no snow on the roof that anyone can see, or a glowing duct in the attic that no one can see without the use of infrared technology.

What FLIR see's is very hot spots along a roof or wall, hot windows or hot air blowing out of suspicious places like ridge vents and soffit's. If they've gotten to the point where they are using FLIR on your house you're already screwed.

I'd also go as far to say that if he has snow on the roof and the heat from the grow is melting the snow his uninsulated attic would be cold enough to cool the loop to a reasonable temp. The return temp just needs to be about 60-70 degrees.


With ducting set up like this in the tent or what ever

filter --> fan --> light--> duct loop --> back in as intake the one fan should generate enough neg pressure to keep the flow from the loop coming in smoothly.

You need to tell me a little more about the set up for me to really have any good advice. Is the set up in a bedroom with the vents blowing into the attic? What are you duct sizes and how many?

Here are a couple solutions off the top of my head.

Take all your ducts and vent them through a roof vent. This would involve taping off another existing duct going through the attic to the roof. Or it would involve installing a new roof vent and ducting to it. Then all the hot air would never come in contact with your attic.

Two - Drill holes if your freeze blocks. If you follow your roof rafters down to where they meet the wall, there is a block of wood closing the gap between the roof and the wall. This is where attic vents are installed. You could either drill 2" holes in various freeze blocks or cut out a couple and install 4x14 vents. The only problem with this is your a renter and if the work is not clean it will stand out.

Three - insulate your attic.

Main thing is to keep fresh air coming in your attic or else moisture from your grow will mold the entire attic in months. Not to mention melt your roof snow.
