Any of you succeeded in a real odorless grow? How?

[twowordz]

Hi everyone,

Here is the situation:

I wanna grow in my condo and still be able to have my family over for diner from time to time.

My last grow was a can fan filter 125 to a 400w in a cool tube and a 170 CFM elicient fan exhausted outside.

I was growing white widow and in the last three weeks I couldn't have anyone at home because the smell was obvious.

Anyone here succeeded in a real odorless grow? How? Please tell me what you use and about your setup.

Also, I am looking for a low odor strain that doesnt stretch too much I could get around 50$ on seedbay, any suggestion?

Thanks,

TW

First, that is a huge filter for such a small fan. Odorless grows are not that hard you just need negative pressure. You need a fan that can change the air in you room at least every 2 minutes. I've got a 900cf room and use a vortex 6" (449cfm) and a can50 that run's 24/7 out the chimney just for odor control. Remember, with neg pressure, as long as air is being drawn in through every crack in you room, it CAN'T escape.

twowordz...Albert has it dead on. Negative air pressure is a must, that's what you need to key in on. Do a search if you're not familiar and make sure you do your room that way. I use a Phat filter, which I really love, and smell nothing even with Bubba, Diesel, etc. I wouldn't look for low odor strains if your concern is just being able to not smell the grow. If you want low odor strains so you can take finished buds with you without worrying about someone smelling them, that's understandable, but again, there are containers on the market that take care of that as well.

You probably want to get a bigger fan, as Albert stated. How many cubic feet is your grow space, and is it completely air tight?

 

[twowordz]

I don't have any equipment as of now, i sold everything before moving.

I will buy a 400w + fan + filter and i will do a ebb&flow setup in a 5x2 closet. So, 5x2x8 80 cubic feet.

Just a thought, don't know how much money you will be spending, but you may want to check out HydoHuts. They are really nicely made. I've never used one personally, but I have seen them in person set up, and they are very good quality. For the price I think it's not a bad deal. They are sealed up, have zipper doors, vent holes with velcro to make them lightproof, removable floor, steel pole frame, etc. They are around 200-250 depending on what size you get. Anywhere from like 3'x3' to 4'x8'. They also make one with a top and a bottom so you can clone and veg in the same room.

One other plus is how fast you can disasemble it if neccesary. Much faster then messing with black/white poly, framing a room, duct tape, etc. JMO, take it for what it's worth, I'm sure some may disagree, but I think it may be just what you're looking for. Just make sure you get HydroHut brand. There may be some made just as well, but HydroHut is the best I've seen so far.

Oh the humanity! Dear god in heaven, NO!

Do NOT get a Hydrohut!!!!!!! SERIOUS plant health issues!

http://www.icmag.com/ic/showthread.php?t=29341 this fan pulls through a cooltube and air cooled hood in my closet i also have this http://www.nationalgardenwholesale....E_FILTERS&title=Air Purification&type=product carbon filter. the modded stanely blower fan pulls through the carbon scrubber 1st then both lights then through stanely and into attick. nothing is smelled untill i open the closet door, my closet is 5ft x 7ft x8ft im usen half now 3 run's i used the whole closet. the filter work's great, purchased oct 06 and still doing what is supposed to.

 

[twowordz]

Hi guys,

First, since I dont want anything to show up, I can't get an hydrohut. I think it can be nice to some people but if I was to go that way, I would just build the sucker.

Hey pothead, nice to see you. Are you positive there is no smell in your attic? I will most likely exhaust right in my living room so I wanna be sure.

About the blower mod, my personal experience taught me that we you try mods like that you end up paying for both the mod and the real thing... How do you hook up the exhaust of the fan to an outlet?

Thanks for everyone's input.

If you just want a grow with no smell, just build a room with negative air pressure. The beginning and end of a grow with no smell is that simple. Along with a decent carbon filter that is big enough for the room you're growing in and the fan to fit the filter.

 

[goldenahms]

Aside from the great suggestions given here--strain wise, I find Power Plant and Northern Lights have been fairly odorless. Or not as strong. Power Plant is pretty close to odorless. Unless you touch your nose to the thing or disturb the buds.
But if you're running a scrubber and something inside your living room, like a candle, then you should be golden.

 

[notjonesinNEmor]

As mentioned the right strain is a must. I attic vent and when it gets really cold the smell will creep back down into the house. I have had good luck adding a Vaportek to help cover smell. Joey Weed NLxC99 was a very low odor strain that only costs $50. It does have some smell when moved, but nothing like pot, just a green plant growing.

negative air pressure(but not too much), a good wquality carbon filter that is filled with good quality carbon. air filtration carbon and water filtration carbon are made to different specifications so aquarium carbon wont last as long as air treatment spec carbon and might not give as much odour control.. It will be better than nothing tho if DIY'ing. finding a stealthy way to vent it out of the space might be a good idea, but if you have to, you could use some plug ins or something... I saw some mini ozone gennys on ebay- only a little thing not capable of producing harmfu;(to you or the greenery) amounts but useful for smell/bacteria/pollen/mold spores. that placed near the thing would clean any residuals.....
But again if you could duct the air away discreetly that would be better both for odour and for temperatures inside the growbox, i guess tho if it isnt an option it just isnt....

we have the parents and inlaws over all the time for dinner etc. and not a hint of smell.

we live on a tight housed street where my neighbors walls arent 10' from either side of me. I have a local LEO that lives directly across the street and another 4 houses down on the corner. stealth was mandatory for my setup. heres how I did it.

My grows are 100% odorless with no carbon filter etc. My grow closet measures about 5'w x 7'l x 8't. about 280sq feet.

I cut a 6" round hole in the top of my grow closet. I installed a 6" vortex in the attic just above the grow room to create a negative pressure exhaust. I didnt want to exhaust into the attic as i figured the smell would eventually creep back into the house and/or garage and I didnt want to invest in a carbon filter that I was not sure it would work 100% so I bought a pipe saddle T to tap into the exhaust pipe coming out of the central heating unit that extends from the top of the heating unit thru the attic and out through the top of the roof.

after cutting out a 4-5" oval hole in the central heating unit exhaust pipe with a jigsaw, I mounted the saddle tee with sheet metal screws over the hole I had cut into heating exhaust pipe. I cut the hole close to the top of the inside roof where it exits the roof. I attached a hose from the vortex exhaust to the saddle T and taped on securely with aluminum tape. I sealed the saddle tee airtight around the exhaust pipe with some sticky spray foam that expands as it dries to fill all the cracks etc. you can buy it at Lowes or H Depot.

this setup exhaust my grow room continuously out the roof of my house which is a good 35'-40' off the ground. there has never been any hint of grow smell in my house or coming from my house. not at ground level anyway....lol

the only drawback to this solution is I cant use a C02 setup as I have to exhaust 24/7 for negative pressure but the stealth is worth the peace of mind verses benefit of C02.

Must not get real cold where you are at.

Where I am at in the winter, EVERYONE in the neighborhood and probably a half mile away would smell that exhaust.

Even if I exhausted outside I would scrub it first with active carbon.

 

[JohnnyToke]

well, its 34f outside right now and that will prob be the high temp for the day. im a red sox fan so that would give you a general idea where I live.

I only grow 4 plants at a time and with the exhaust being pumped out the top of a 2 story house at about 40' above ground level where the wind blows constantly, no one smells it winter or summer. its not hard to disipate ganja odor that high above ground with a 465cfm vortex.

the only thing you smell in my neighborhood is burning wood from all the fireplaces....

im not knocking the carbon scrubber method as I have never tried it. I was offering up advice on what has worked for me. trust me, with 2 leo's living on my street within a sandwedge shot of my front yard, I gave every scenario careful consideration.

im not a seller so I dont have any unwanted traffic attention drawn to my house. we bought this house in 2001 and we have neighborhood block parties several times a year where we all get together for bbq's and drink beer. this includes the leo neighbors. no ganja smells anytime of the year. its all good in the neighborhood.

[YwouldntI]

a quik question if i could.i have a carbon filter in my room.i mounted it in the room and have the fan behind it drawing the air thru and out the chimney also about 35-40 ft up.will the 440 cfm.fan be enough to exchange the air in the room as long as my intake is strong enough?heres a pic of the setup and garden any help would be great.not tryin to thread jack bro its just i dont want to start another thread to ask the same exact ? as you,ya know peace-Y-
the black fan is the one hooked to the filter


this is the filter

and here is the garden that im tryin to filter there is 30 in this room now it is for flower only i plan on adding 10 more to flower every week to ten days thanks for any and all help peace






again bro dont mean to be jackin ur thread peace

 

[JohnnyToke]

your room is a lot larger than mine. your air that is being exhausted out of the room is carbon scrubbed already so there is probably very little smell if any exhausting out of your chimney. especially if your fireplace is being used.

I would think that if you are exhausting the grow room all the time (24/7), the air exchange in the grow room should be sufficient however there is some cfm loss due to air being pulled through the carbon scrubber. if there are no heat problems in your grow area, then you should be good.

if heat buildup is a problem or becomes a problem in the summer, you should probably go to a larger fan to move more air.

Excellent answer Johnny Toke

Excellent answer Johnny Toke

Heat build up is an excellent factor to use to gauge your air exchange. Even with sealed vented hoods temps will climb to unacceptable levels in an under ventilated room unless its 100 degrees outside with little insulation for the room. One other factor though is if you let your carbon scrubber get too old. That looks like a fairly small carbon scrubber for that many plants IMHO. The carbon molecules will become saturated in less time than a bigger scrubber.

One thing to mention also is the higher the temperature the more plants smell. I run at 85 degrees with CO2 supplementation and can definitely smell the difference from the 75 degrees.

Just some thoughts.

Peace

 

[twowordz]

Thanks for the input.

I cant exhaust outside here but I have a good idea of how i will do it.

DIY is over for me, last time I paid my whole setup after a run so I will go for peace of mind.

Must be the humidity levels then. Here where I am at when it is around 0 F the humidity is VERY low, and I can smell restaurants 3/4 a mile a way at that time when I step out to take the garbage out in the evening. Odor must cary very well in dry air, because I can NEVER smell the restaurants in the summer or springl here when the humidity levels are much higher. If I vented into my chimney without scrubbing it, it would smell everywhere outside my place at those times. I bet I could get away with it if I lived closer to water or it did not get so cold here.

There is a reason odor is in the top 2 list of what gets people in trouble.

I only run 1 or 2 plants at a time and if my scrubber goes down due to a power outage or something, my entire house reaks of it in an hour. It's amazing how the smell can permiate everywhere so fast. (Late flowering of course)
