Much respect. You certainly have your work cut out for you, scrogging that many plants in that kind of space. I cut down from 6x600w to half, because I got too lazy for it 
Kudos also for answering all these questions in detail - that's rare, especially for the bigger growers.

just got my first doser. grow store had some ancient model sitting in the shelf for 6+ years no one bought. i was asking about them to the manager. he kicked it down and said he was glad to be rid of it in his space. so i am going to get to autofil tank. im too chicken to dose to fertigation system directly yet. thanks for the inspiration.

Secondly thanks to all the knowledgeable growers here who have kept DJM on his toes by asking the tuff and technical questions. And third I havent even seen if this is a sticky, if not with all the knowledge assembled here, it's a shame if we don't sticky this.It's pure growtread ABZ. Keep it coming folks. Jus my 2cents.

DJM, Thanks so much for posting all this amazing info.
I have a question for the community.
I am trying to convert my 16k test room (4x rows of 4 lights) to do this multi feed.
This is what I came up with.
Is the pump too small/ too big or fine for a 16k 400 site room.
Should the main line be 3/4 or 1"
Should the drip lines be 1/8 or 1/4"
Also around how many foggers to raise the humidity up in a air conditioned room. Its currently at 45 during lights on. I could hit 70 or 80 during lights out though.
Any opinions are greatly appreciated.

It goes from the pump through a filtered single mainline, then split into 8 Main lines. Each mainline will have 50x drip sprayers down the 16' run with 1' of drip line off the main going into the pots.
I am guessing I should run 1" for the single main line and reduce it to 1/2" or 3/4" for the 8 mainline split to keep pressure.
The room is almost a perfect square.
This is the room layout.

Lots of good info here, thanks DJM. Your diligence/dedication/adaptability is impressive. You seem to have optimized plant metabolism. Not may folks on here dropping knowledge like this.

anyone have any insights on if he runs the inline fan, hooked to ducting in between lights, directly to the exhaust fan?
Or are they separate from each other?
Also DJM you mention you run 3 fans during the summer, I assume the intake and exhaust are 2 of the fans. What is the setup for the third fan?

I think he just uses the fans on the intake, while allowing for a passive exhaust thru a carbon filter. this creates the positive pressure that allows for more humidity to stay in the room in the low rh Colorado environment.
Also he uses vertizontals or similar for reflectors, so no inline fan is involved for the lights to be exhausted. I think what ur talking about is just where the intakes come in and get spread out around the lights n canopy.
Hope that helps.

Thanks for taking the time to respond.
Yes I went back through the thread and he does indeed have a passive intake for the exhaust, I must have missed that part.
I understand he uses vertizontals so there isn't any direct ducting through the hoods however there is ducting next to the lights that is hooked up to the intake.
What i'm wondering is where the other end of the intake ducting goes? Does it hook directly into the passive exhaust? Or just hangs down to the floor (you can see in some pictures the intake ducting hangs down towards the floor but I'm not sure if that is the end with the intake or the other end.)
So if during winter he only has 1 fan (on the intake) but during the summer he has 3 fans, where do the other 2 fans go during the summer. Does he run 2 more ducts between the lights with intake fans?
I'm so Frickn glad I found this thread. I can't tell you how much I've learned since yesterday when I started reading. This thread needs to be a sticky. I recently put a dehumidifier in my grow room since my temps and humidity were in the 80s. Last nite I traded the dehuy for another fan. Thanks for sharing your knowledge, i know I'm not the only one who's had bombs dropped on them from this.
Unfortunately not every thread can be stickied. But threads like this thread that others find useful can be found easily. Just go to the forum you want to know more about. At the top of the forum above the stickys in the center is a button that says ratings. Click on that and the forum will be reordered with the highest rated threads pulled to the top.
That is why people need to vote for the threads they like or dislike. If no one votes the best will get lost in the mediocre.

WT helped cover it for ya, but ill add to make it clear, when the summer temps are warmer, he just runs 3 intake fans(instead of 1 in the winter), with the same passive exhaust. Idk if it matters with extra ducts. ultimately its about consistently keeping the right temp n rh, with using little extra electricity to accomplish it. diminishing returns u know.
So with the extra fans, if u need more ducting to equal temps n airflow in the room, then go for it. Just start with the extra fans needed to cool the room properly, then if u have warmer micro climates, add more ducting. U have to check temps around the whole room and canopy to really know if u need to duct air to that spot.
