End all Be all of Sealing a Room thread??

[Dreamscape]

A true sealed room has no intake or exhaust. It is pricey, but definitely worth it.

So then what do you do about heat ?? Run an extra A/C or something ??

Also how much would a c02 set up run ??

More than an intake and exhaust fan with ducting i'm assuming ...

I mean, in the room you're speaking of which has no intake or exhaust the only difference is no intake/exhaust fans and Add a c02 set-up, correct??

You can still get the negative pressure effect with the intake and exhaust though right ??

finally a discussion on sealed rooms! i tried to get one goin a little while back but no avail!
i agree with l_d_d, a sealed room is just that.

seal it good, no intake no exhaust! you MUST have a/c, CO2 gen or emitter, and a CO2 monitor. you'll probably need air cooled lights too. you have to spend big bux, but double your yeilds. and reciculate the air through a charcoal filter.
for a 12x16 med gro with 5400w:
i got a green air CD6 CO2 gen (i got it used but theyre about $600), a sears 10,000 btu DUOBLE HOSE (important) portable a/c $700, and i have yet to buy the monitor. theres the matador brand, which seems the best, its $1K, and the CAP ppm3 which is about $600.

i havent taken the plunge and sealed yet, i dont have the CO2 monitor.

lets talk about this more, anyone ever done it?

Well for a TRUE sealed room...as in 100% NO external influence...you must use equipment that is fully capable of controlling every aspect of the environment WITHOUT an intake/exhaust.

AC or heat
Humidify or dehumidify
CO2 level
Filter the air within the room
etc...

 

[whoamI?whoRu!]

double your yeilds.

How do figure that a "True" sealed room increases yeild by any noticable amount over a standard room setup that uses all the same equipment but also uses an int/exh? Especially double?

1500 PPM CO2 all day can only be achieved in a sealed room. its the only way to do it without wasting CO2.
not true, but "perfect"

 

[Dreamscape]

I'm sure this isn't going to be one of those questions you could pin-point without some disgusting amount of monitoring BUT -

What would you ASSUME MIGHT be an average level of C02 that is brought in from an intake which pulls its air from the outside ?? Just give a ball park if you can...

~Dream

PS. Any cheaper equipment alternatives to what has already been listed in terms of C02, monitor , ect... ??

 

[irie-i]

thats easy dreamscape, ambient CO2 in most places on the planet is 300-400 PPM

there are cheaper alternatives to CO2 production, but they are unreliable, work intensive, and good only for tiny grows. there are no cheap monitors.

So just curious as stated above "Filter the air within the room", why is this necessary. What is being filtered....? The smell doesn't seem like it would be a problem if the room is "totally sealed".

smell can go through brick, so filtering is always needed.

Ya, I don't think it's for odour control exactly. I haven't done a 'sealed' room...but I have read a lot of good info and about setups on them. They all ran a carbon filter. I think it's to keep the air cleaner? Capture pathogens, spores etc..?

Nightfire...brick shouldn't be relied upon to have a sealed environment...'true-sealed' or not

 

[irie-i]

a room full of dank stinky flowers can permeate anything. the air must be filtered

I was using brick as an example. Unless you are able to make a room air proof smell is going to get through. Even if it can be made airproof, when you open the door the smell will roll out.

A sealed room and an airtight room are not the same thing in the context of a grow room.

A sealed room is a very controlled environment where there is no free flowing air from the outside to the inside, however, air will get exchanged. There are the cracks in the door, the ceiling (drywall and plaster both breath) and the floor (concrete also breathes).

For an airproof room you would have to use non-porous material all the way around a room to make it airtight, the walls, ceiling and floor would all have to be non-porous. Metal and glass would be the most financially feasable way to do that. It would be very expensive.

I went 1/2" plywood, interior doors with custom made casings, lots of silicone and 40mil pond liner on the floor. The pond liner is the shit, very tough, you can walk on it, twist on it, slide your pots around and it doesn't tear.

holl shit home depots makeing a killing of the tarp zippers!!!!!!! if theres 24 in a pack for 12 bucks. THEY SELL THE ZIPPERS FOR 13 sumthing rofl !!!!! they sell 1 and there allredy makeing 100% profit ROFL!!!!!!!

i am in the process of constructing a sealed room (check my thread for details) with Bio Buckets inside, so this is just what I needed.
I am thinking about using GreenAir CO2 generator and air conditoning (12.000BTU or more).
See you!!!

Is the smell really able to pass thru drywall? Seems if all seams were properly caulked, includings baseboards, trim , light fixtures and electrical sockets, then several good coats of paint would seal a room. Properly sealing a door is another story.

 

[NightFire]

Make a carbon scrubber for ~$50.00(USD) and you won't have a smell issue.

For smell permeating drywall, think of it this way, when someone is cooking, can you smell it? You might be in the back of the house, and smell dinner cooking, or walking down the road and smell someone cooking a few houses down.... Smell travels very well....

Paint is designed to breath, oil base will seal things up better than a water based paint. (a water base is anything that uses water for clean up, where an oil base is something that you must use a petroleum based cleaning agent like mineral spirits)

Best odor control for a sealed room bar none is a vaportek optimum 4000,it'll kill the smell of rotting flesh I guess it'll take care of the smell of pungent buds

 

[TheSource]

it'll kill the smell of rotting flesh

well I'll keep that in mind then
