I agree with dsw the 8" isnt enough. Ds ill tell ya as an internet friend i think you're being a bit harsh but you know correct cfm needs. Lets all chill and help each other here in a friendly manner
Unbelievable.

What he saidIm with ya dabs.. I read the thread n i thought dsw was trolling. U did mention several times that the build was in progress.. Good luck
Oh and two other things You definitely need more in room circulation fans. Too many people skip on this extremely important principal of room building, and end up with less yield and mold as a direct result (the problem just amplifies with more lights and plants). Second, keep in mind that once you attach a carbon filter to any fan it's only producing maybe 50-60% of it's rated cfm (less if you bought cheap fans). Doesn't look like you do, but had you needed to add duct you'd be getting even less cfm (i.e 1 90 deg turn in duct costs you ~40% of your fan's cfm). OVERKILL is under rated, sooner you figure this out the better you're life will be. Trust me
His advice is worthless to me... He's an arrogant prick...
And apparently you still aren't able to do simple math. Have you ever built a room with 2 separate intakes like you're talking about? I am willing to bet it's a big fat "NO".. and you have no idea what you're doing (but that's clear). Using 2 different intake fans is going to screw up the pressure in the room.. though i'm not sure you even care since you already admitted you were basically doing that on PURPOSE.. which is 100% backwards according to any book you read or horticulturist you talk to. (Me).Also, the inability to read in this thread would have saved a ton of bickering! It's not fucking done yet, ... I already said 6 pages back that if one 12 wasn't enough I would add the other 8 inch fan.
You're done updating because you thought you were going to get everyone on here sucking you off. That's not going to happen when you're doing things WRONG, and it's blatantly obvious you're not willing to even take simple advice from more experienced growers.Thank you all for your amazing advice, it was greatly appreciated. I'm done updating this thread have a nice day
I've done 2 4k watt grows In a non insulated garage w/ a 8'' intake and an 8'' exhaust no problem...I still am having a hard time finding the problem.

What he said
Reg
wow...though knowledgable...that dry sift dude was a little pecker. Sucks to watch a condescending dick fuck up a thread...
Enough airflow?? I know the recommended rate is 2x air exchanges per minute
30ft long x 9ft wide x 7ft high = 1890 ft^3
3 x 750CFM 8'' Fans pulling air out = 2250 ft^3 (of course that is ideal, probably closer to 2000ft^3
So my exhaust only exchanges the air 1x/ minute, which i know is not ideal, but it will almost certainly be enough.
Yes, you did. Except you went out and blew all your money on lights you don't need.Unfortunately we're not all big ballers with 50k to drop on their dream growroom, and someone to build it for them. im workin on a budget over here..I dont have enough$ to buy 2 x 2000 CFM fans, or the carbon filters to attach them to
You blow the air directly under the canopy while the air is cool. Not after it warms up and stales. Cold air is denser than warm air and given a set volume, cold air will contain a more dense accumulation of oxygen and nitrogen, which is good for the plants. Warm air being sucked up through the canopy after being brought in and allowed to warm up will defeat the purpose of fresh air to a certain extent. Simple science.I also have a 1050CFM fan as an intake...Plan is to blow it down towards the ground around the edges of the long walls of the room (on both sides of the plants)...Then as it warms, it'll get sucked towards the middle and up and out the exhaust...
I didn't call it a failure, and those plants are in fact drooping. Simple observation.Not sure why you're looking at this as such an utter failure and causing "droopy dying plants"
Suffocating plants = killing them. It's a weed. Just because it'll grow doesn't mean it's correct. Lots of people grow decent herb even though they honestly have no idea what they're doing outside of just putting light on them and watering.As far as the veg pics, those are my girls, hanging out in a buddys garage while i get shit figured out over here. The environment is far from ideal, in fact there is no environment control whatsoever.., but chill the fuck out eh? They appear to be growing just fine...and are far from dying.
Yeah, no shit. So pay attention and learn something.. strange concept I knowz.Thanks for the genius reply about moving the plants. Obviously the easiest way to not stress plants while moving them is to not move them in the first place you hit the nail on the head with that one.
And to be 100% honest with you, you're right. If i could i woulda done 2 or 3 or 10 rows of lights, but real word hit me and I was constrained by the size and layout of my basement...Thus i chose to do one row of 12 lights. In the future, when i have enough money to outfit 2 rooms prostyle with CO2, I may just do that. Until then I'm gonna take the budget way out.
@DSW i have been reading herb forums for a decade... and your posts in this thread (accurate or not) are some of the more abusive/disrespectful and all together just uncalled for.
so u build rooms for a living... dabs is not paying u. if he wanted ur advice he would have asked. he obviously is not receptive to your tone... or your knowledge. So wtf? cant the guy have a thread without u jacking/trolling it? there arent many threads on ic as it is.
i know im probably wasting my time and you will proceed to tell me what a pussy iam, and how i cant grow for shit ...blah,blah ,blah.....
Many people need to learn from experience.... not by having anonymous internet users give them condescending advice on an unfinished and budgeted build out.
basically what im saying is its NOT about the info or knowledge you are trying to "share" with dabs... it is HOW you are saying it. Either you see it and know you are being a jerk, or you dont see it (and have trouble with human interaction in general)...
either way, as a self proclaimed "expert" in human interactions I would tell you that you are going about this all wrong... if ur goal is to get dabs to implement your proposed design changes ud do better with honey than you will with vinegar.
Also, wtf does it matter to you, if dabs builds a 12k room that is overlighted and under ventilated? It all comes out in the wash right? itll only take 3 months for that to become apparent. why not let life be the teacher... why do you have to be right? right now...
does it matter? do u have some stake in this? or are you just offended in general by not perfect grow room design?
whats really funny tho is they left the information there.. it really is good info to know.. not sure why everyone is so pissy..
So he tried to help.. don't like it.. don't listen. Pretty simple.. but I see nobody giving him reasons why hes wrong.
