With 3 tents (2 flower ) inside a lung room, do you ventilate tents continuously and match lung room to tents, or do you control tent environment using lung as reservoir of controlled air?

Lung room-how do you do it ?
- Thread starter Cannabis Critic
- Start date
If you vent your filter into the room, you could try adding a plug-in air freshener inside your tent. This mixes with any odour making it much less noticable. This should be very slight indeed after passing through the filter. May also give you an idea of how effective your filter is. I refill my plug-in air freshener liquid; with any brand-type if it has a cheaper sale price. I have used the same one for many years. The plastic lid comes off, and I just pour the liquid into the one which fits the plug-in.

Would this be better than the smell of a charcoal pond-weed, with peices of duck feaces spread on it?

Comfortably numb!
Say What?????
The tents each have their own fans and intake, and the exit stream merges before it goes out the wall. IMO, venting to outside is critical. I put 2 gallon into the tents each day, so that much is going out from the fans. The air that come into my room mostly has to go through a 25" x 20" filter and carbon screen that also helps block light and odors from getting out. Dehuey in the room (screws up the temp, I need to vent it outside also), hueys in the tents if needed. I am keeping the lung room at 60%, which is also good for drying. The air is A/C to 71*.
I like smoking doobs in the room as all the air is venting outside through the tents then a carbon filter. Plus it smells good in here, so I set up the office now. More CO2.

Would suggest reading anything from DHF, master of optimised environments.
Lung rooms are for those with AC, which is not on my menu.
Live in a one bedroom where the plants got the bedroom, hall and good part of the living room.
I have a kitchen and bathroom.
Have 2 arrangements, in the winter time, the tent exhaust runs inside to help heat.
In the summer time, the exhaust goes outside to keep the temps lower.
"Day for night" with flower cycle. The cost of power is reduced at night.
Cut back to veg hours of 18 hours with the six hours of darkness timed to the peak heat of the day.
The grow room has small windows which face South and West. Each window is wide open with fans in them.
South facing windows have fans blowing out, West facing windows have fans blowing in. Fans run 24/7.
I put steel screens on all windows, which I run a brush over frequently. Need good airflow.
Have individual filters on the intake of each tent, which get swapped out as I go from veg to flowering.
LED lights and pushing air keeps flowering temps in the low eighties.
Fans on in tents 24/7 veg to harvest.

Sounds great. The problem I have with venting to the outside in summer is all the hot air that gets pulled in from the negative pressure. I only have 1300W led light, so in the winter I have to add heat.
My tents have AC Infinity controller fans, so a lung room at 70F & 60%RH would be perfect. The only thing I’ve been able to do is dehumidify recycled air and blast the ac.
Lung room is inside garage. styrofoam insulation walls around tents. Any suggestions?
I’ve never thought to vent hot air from dehumidifier! Once again let the ac battle the hot dry exhaust and get dehumidification from both. Any dehumidifier performance issues when venting exhaust?

P. S. To the people currently suffering through the record setting heat; I hope you are well.

Thanks Gry. I have read the sticky on ventilation a few times. You’re right it’s good stuff.
I couldn’t imagine not having ac in summer…

I am going to look for posts from DHF, thank you Gary.

Install ducting to connect the air “manufactured” in the central room to any number of separate grow rooms that return the air, after carbon filtration, with a fan back into the lung room.
I'm hearing you have a sealed room. Within it, 1300w of light, giving maybe 1000w of heat. Then a dehu giving maybe 300w more? And this heat only leaves via the aircon, which is only the evaporator part, with the heat being lost outside somewhere. With this, you are running hot.
If you send the air from the tent outside, that draws in outside air which is too hot for the aircon to handle?
What if you gave that warm air from outside, a duct to follow, that fed the aircon directly? So all intake air had to go through the aircon.
Have you looked at a mini split?
You really need some exhaust, to switch off that dehu and get some co2 to build plants with. Old depleted air is wasting your time.
You didn't name any of the temperatures, but with leds, I wouldn't be that concerned at 34c if it gave me some air. It's not ideal, but only as bad as 10% less co2 in the air. Around 36c you would go over a cliff, though all figures are +/- 2c. I have just had 32c and it was some of their better days. Feed need lowering though, to allow them to drink more water without the root ec climbing until they can't.
What lights? Mine are air cooled, but didn't come that way. I have done this various ways. Perhaps you can take most of the lights heat away, using air that enters your sealed area, passes the lights, and leaves. Though a duct system that's sealed from the room. I bet I could show you how.

Air conditioning the air in the lung room, or the air that makes up what is expelled from the lung room, is essential. Venting the tents outside is essential. Filtering the lung roomintake air ia also a good idea. I need to get off my lazy ass and make filtered air intake boxes with a controllable fan to supply the air from the room into the tent.
My tents have the fans on a constant speed that works well. The AC Infinity controllers are not really worth the hassle. Maintain a good lung room, and the only thing that changes is the tent temp, from the lights being on or off.

Welcome CC and thanks for the kudos Gry Bro............Not sure my old ass is a master of anything except maybe master baiter.......as in fishin that is......lol.....Being retired now for several yrs and only growin for headies and sleep meds , I also find myself growin in tents compared to my old framed in flip rooms in full underground basements with lung rooms supplying perfectly conditioned air into and out of said lung rooms ftw utilizing air exchange twice per minute religiously to keep CO2 inherent in the air we breathe at as high per ppm levels as possible.......and yeah......
In deep summer I used big ass wall banger a/c ` s in each lung room to help keep temps from soarin where I cropped hard for more yrs than I care to remember in the illegal Hell state of the dirty deep south where I still reside and wouldn`t think of bein anywhere else , but I digress......now.....Let`s get into the basics of lung rooms and their functions.....First off , my old rooms were 6 x 6 with 1800 watts usin 3-600 watt hps fixtures in each 1 , and I assure all the heatgain from hps lights is the 1 main issue to deal with in the quest for perfect environment when growin dope long before outside air comes into play.....that said.....the lung room areas were as big as possible to utilize as much cool basement air to help pump in and suck out as close to perfect environment as possible 24//7/365.....and.....
All my rooms ran in the low to mid 80`s with dialed success regardless of all my pot snob critics from mostly the left coast claimin that terps are all but destroyed and disintegrated from any temps over mid to high 70`s , and to that I ` ve ALWAYS claimed horsefuck since my dialed in clone only Chem D bitches forever more made em eat their words with it`s funk of all funks but again.....I digress.....Also.....Since we`re on temps , LED ` s are at their best and at optimum conditions with higher temps in said grow areas , so I suggest you stay in the sweet spots of low to mid 80`s and as high a humidity level as possible....even as much as 75% for proper VPD levels all the way through end of stretch , and then once full swellage begins , lower it to as close to 50% as possible to prevent airborn nasties from proliferating in said grow areas.....and again.....
I can ` t stress enough the importance of air exchange twice per minute as well as wall and floor fans to create as close to a vortex of air inside the grow areas while never pointin said fans directly at the plants , but rather above and below for optimal circulation that all but guarantees no molds , mildews , botyritis , etc. , etc. can form durin late bloomage till end of cycle when the plants are drinkin and swellin for all they`re worth till chop time......Pointin fans directly at the plants causes em to sweat/transpire , and that in turn causes excess nutrient uptake which if not kept in check will cause ph imbalances and lockouts with shit goin sideways all but guaranteed......and lastly.....
Growin in an un-insulated garage is an uphill battle at best if you don`t attack said room with a vengeance to control temps as much as possible , and I see your attempts with styrofoam insulation are indeed well warranted , but I wouldn`t stop there until the garage is like a damn igloo cuz with the sun beatin down on that roof will absolutely bake that grow area from all the heatgain in the attic 24/7 , so.....insulate , insulate , and insulate some more just for absolute insurance.....anyways.......
I don`t post and not around much these days , but I`m around , pm`s are open , and happy to help whenever needed so.....Good luck , take care , and......
Peace.....DHF.......
