Thanks everyone for the support! I'll be adding more info in a few weeks. I'm writing up some more detailed information and planning on getting that $5/mo subscription next month so I'll edit in a big chunk of info all at once when I get that.

Let me guys know if there's any topics you'd like covered in more detail or anything that I was too fuckin high to explain clearly enough!

More to come soon!

Well I've been busy with real life crap for the last few weeks as well as my computer committing suicide so I haven't had any time or way of updating this thread. Now that I've got my new computer and (hopefully) some well deserved vacation time coming up (finally), I'll be adding to this thread some time soonish (if everything works out). In the meantime, shameful self-bump so maybe one or two more people can learn from this thread before it disappears to the depths of page 15 again.

christ, i am just gonna stick my plant outside in the sun with some pink plastic coloured flowers stuck on with superglue as a disguise, cos by the time i read through all this it will be fully grown and i will have forgotten what was written at the start and i would have to read it all again.
 
^ I bet that would work in some people. I had a 7 foot tree growing in my backyard last year, and most people didn't even realize what it was, or that it was real.

So I am venting through my dryer vent using a Y duct. The issue is that my exhaust fan is so powerful it pressurizes the dryer vent duct and send the smells back up into my dryer, so it smells like I'm growing inside my dryer. I tried using a one-way flap in that duct which did keep probably 90% of the odor out of the dryer, but then when you run the dryer it gets HOT as the duct flapper thing is restricting the airflow from the dryer. I don't want any fires etc. and am wondering if anyone else has found a way to successfully use the dryer vent for both growing and drying clothes without having to disconnect / reconnect each time the dryer is used....which is what I'm doing right now.....

Personally I used to do this when I had a smaller grow. Haven't had experience with this issue since i was only using a 250cfm exhaust there wasn't a pressure issue due to smaller scale. I would consider trying to place your y closer to the actual exhaust point of the duct, the closer the better. If that doesn't work you could try putting a valve of some sort in the duct so instead of connecting and disconnecting you just flip a lever when you need to run your dryer.

you could also attach a booster fan on the end of your y split. This would cost a bit more but definitely solve your problems with air going back in your duct.

well to each his own. I personally think if you're going to grow do it right, and if you aren't willing to pay attention to the details on the most basic components of your grow op you'll run into problems down the road. Preparation and thorough planning often shine through in the final product. The whole stick it in the dirt and see what happens method is fine if you dont mind wasting years tinkering around instead of learning from the experience of others.

Glad to hear it! Sorry haven't updated the original post but really anything I haven't covered is more of a specific question thats tough to generalize. Glad too see so many people getting some use from this guide!

Exellent post man, there is so much bad information on ventilation here its astonishing. People often just assume they will need a bunch of A/C running, or worse set up their room assbackwards so that they use a bunch of A/C that they don't really need. reps to you

Hey Great Post.... Thanks for taking the time to explain this to a newbie like myself. I just purchased a cabinet for a diy project, I am basically trying to copy SuperClosets Deluxe 2..0. I think I have a good plan set up for my project. I am just a little confused, I am going to be using a passive intake system and use a 4"carbon filter with fan to extract air. Is the rule that I need three 4" intakes. I appreciate all your help...

hey so here is my current led/hps grow tent set up. After reading ur thread im a little more confused then ever, haha. ok so i own -
4x4x8 dr120
4 inch inline fan
600 cooltube hps
360 watt led penetrator
2 oscilating fans
2 cfm booster fans 70cfm maybe a little more
hepa organic air filter
6 inch and 4 inch ducting
3 trainwrecks and 1 sfv18 smartpots 5 gallon veg 6 weeks SCROG
1 loving supporting girlfriend

keep in mind lights on are at night AND i use the heat from the tent to warm my room
ok so here is how i have my setup i use the inline fan that sucks cool filtered air from my window, blown right underneath the thick canopy,
i have one booster fan suckin hot air out the cool tube,but at the same time sucking cool air in from the window. (this is where one of my bigger heat problem might be at)
then i have one booster fan throwin out hot air from the top of the tent. I KNOW I NEED TO INVEST IN A CARBON FILTER, WILL DO SOON.
so i never peak over 82 degrees and it never gets under 74 degrees, leds due produce heat plus i think my booster fan isnt strong enough to suck hot air out the cooltube? and also maybe my booster fan isnt enough to suck hot air out at the rate im blowing coo air in?
anyways IM HIGH.
let me know what yall think????? im open to anything OH AND I HAVE A CO2 SYSTEM, I KNO I CANT RUN IT IN HERE, BUT IF ANYONE KNOWS SOME WAY TO RUN EVERYTHING THAT WOULD BE NICE! also have better pics, if yall intersted i can post more laterz
peace from ALL OF CALI
