glad to see this was stickied
wow!
this thread has swelled to almost a 100 pages.
anyone know what brand of coir DJM uses?
was it something like just coir, by black gold company
Hoping someone can give some opinions and understanding of the passive exhaust ?
someone posted one benefit is that by having a positive pressure room is a benefit for mold spore and insects ?
Im wondering how much an issue smell could be ?
Anyone running or have ran possitive pressure rooms ?
Im currently setting up a room with passive intake just because thats how i have always done it !
I have ran possitive pressure in vented hoods due to neg pressure hoods could cause smell ?
This is a legal room but it doest hurt to be stealthy these days either way.
one question for DJM if i may...Earlier you mentioned you also ran organics any reason for the switch to synthetics?
Also any tips on a good mix for organic soil start to finish amendments per cubic foot etc etc..
I changed up my whole set up because of this thread.
This is the #1 source for coco growing info I have found yet. I just copied as much as I could.
I learned a lot about how to properly set up a room. I was skeptical at first but the way it was explained here made so much sense as soon as I heard something similar from a reputable source, I was all over it.
I have way more control over the things that I can control now.
One of the major points I liked was we shouldn't be going below 65% rh (depending on...) but for the most part if we wouldn't want the drying process to get below 65 we should strive to keep it at least at that point.
I heard a very similar theory regarding temps. I listened to a wonderful lesson on drying and curing from the Wonderland nursery director and learned that 82 deg should be the upper temperature limit due to that being the point where we start to "burn" the terps.
It makes a lot of sense to me and was wondering, how do some of you all with controllers balance out your temps vs rh?
Big ups to DJM and the whole crew.
thanks gnome!
ive used a ton of coco over the years...hope that helps
Sorry to double post, I thought I had added this question but Was using my phone so I must have screwed it up:
Could you give some info on what controller's you use and why? do you use a system where there is an "overlord" kind of controller that runs the whole show or separate controllers for the different variables? I know my needs will be much different than yours as my scale is much smaller, a 5x5 tent. I still need to use controllers/timers/etc though due to time away because of work. as a luxury, it'd be really interesting to have a system that had real time logging of temps, RH, CO2 or whatever. at my level though, it's hard to justify the cost of those systems, especially the internet/cloud accessible ones.
appreciate any experience you have with the various systems.
Thanks,

My Saturn 6 is still doin a great job but they got updated versions next level shit now like the iponic6 that's just in its own class.... the iponics are excellent the customer support is great gives u complete control from anywhere ... worth every penny to have it all in a phone... for a 5X5 tent the practicality of one of these is pointless...
Another question is how many environmental pieces do you need controlled? Are you running CO2 in a tent? Do you have both a humidifier and a dehumidifier? Heating and cooling? Do you need want your fan speeds automated? I think if you define what you want automated AND what equipment you need controlled....it will help with the decision making process. FWIW - I also have a 5'x5' tent and just use separate controllers.That is my dilemma, how much money to go in for given my grow size.

I use autopilot digital master greenhouse controller and blueprint digital atmosphere controller..they are pretty much identical and I use them both in the same way , some rooms have one brand some rooms have the other.
I run my humidifier , c02 and intake off the controllers. My dehumidifiers are the only thing I don't run on it because they have thier Own digital thermostat and I only run them at night anyway. When I use acs I have a ttrigger cord that controls the ac, that I plug into the cooling input that I run the iintake off of
If you are going to get a controller, get digital or don't waste your time. Analog controllers are tremendous pieces of shit. I've tried over a dozen , they are all in storage or thrown away. If you set for instance , your intake on a analog , set to 80. The controller will most likely not kick on till down to 75, and not kick off till around 85. Most of them have a huge dead band of 5-8 degrees and end up with a massive swing in enviroment which is the opposite of what we are trying to achieve. With digital you can lower dead band to 0.2 of a degree. That makes a day and night difference to the efficiency of a controller and how stabe the rooms is.
The rest of the grow, feed pumps, drain pumps, rez pumps ect are ran off titan programmable timers.
If I was in a 5x5 tent I really wouldn't bother things like co2. I'd just run sealed air cooled hoods with a thermostat set to 80, with ducts intaking outside the tent running through lights and back outside the tent keeping tent sealed. Then id run an exhaust on a humidistat set to 70% humidity. They sell "titan digital enviromental controllers" that just control temperature and humidity. They are only around 160 bucks and I'd recommend them over a controller with co2 for your situation. Controllers get far more expensive when it has co2 controls usually more than double . Doing that you can still run vpd at 80f/70% easily without many moving parts. In a tent it would be hard to try and replicate a 85f 75% room with humidifier. And if you werent running co2, youd want temps and rh lower. Since you are limited in space you need to approach things very minimally. With a simple design like that you can do very well in tent. Hope that helps
