Ok, this is my first grow with a burner and a ppm controller.
Bought a 2 burner, pretty nice unit, made to hang from ceiling. Keeping it rather low to the ground. And am plugging one side to leave a single burner.

Bow your room needs to be TIGHT. Unless you are using like those sheets that you mist by hand. They just extrude c02, hang high and will drop onto plants. But is limited in control and amounts.
From what I understand, is the more even the ppm is during the day (night needs to be drained of as much c02 as possible!
Babies need nothing, actually. May cause stretching. So it's been quite a time trying to keep it LOW. my own breath will increase ppm 1000 points!
So have been trying to stay around 1200 or lower.
Still must find the plug, get a tank refill. Wat am I waiting for...? Fine, I am ordering tonight....

Is your product requiring testing?

With burners venting is needed periodically.. with bottled not so much. Plants don't take up co2 at lights out so the ppm really doesn't matter.

You may find a need to feed a bit more and definitely want to make sure you have enough light to take full advantage of it.

Higher temps and lower humidity are beneficial with co2 and I would border on saying necessary

Yes, inline with you there. So keeping low humidity presently is not an option. Dealing with other matters (check out other threads), they are just now trasporating and growing. Live in desert with extrems from outdoor environments.
Check them out....

Venting occurs when opening and closing door! Inside grow, tight seal, single burner with proper ppm controller. Simply will not overload area before reaching meter, where it will pick it up. I would not screw with this without one...

deploying c02 next week for first time, looking for fan controller that will run fans only once lights are off, will use timer for now

Ya that’s what I run currently. 2 burner from titan. I use it in a 10x10 lung room and use my cloud line to pul it into both my 5x5 flower tent and my 2x4 mother tent. You’re plugging one side? What size area are you enriching and what are the problems you’re having?
Just a programmable timer will work. Can set time and duration. Calculate the room in cf and then take the fan cfm and divide the room cf by the fan cfm and thats how many minutes you need to run the fan to change the air in the room provided you have good mixing. I would say if you double the duration you can consider it sure to do so.

I was going to say the same. I have half my shit smart switched. I found some sweet 15A smart switches after I burnt out a few running a 1000w hps and a few hundred watts of leds on the same line lol

You guys crazy. Just spend the dough (DOH!) and even it out. Gives an assurance, that your obviously constantly leaking. Not good either withing home environment, seriously.
Seal up better with shoe goo, did my whole room with staples and shoe goo!

I run a sealed room never vented with bottled... however I would not do the same with a burner... that has to be periodically vented your call though. Just a warning.

Or maybe I'm to Hugh and reading wrong here.

To Hughe? Awsome saying!
Naw, I am just using a ppm controller. Set and forget. Bottled air or propane? I ask because you may want to put these items on your list, after say a harvest.
What happens apparently, if even out, cuts off at night, then if you use cold co2 from bottle, you can get the "fuzzy logic". Cannot use for burners.

Does "fuzzy logic" work? Good question, cant use it. Must pipe with spaghetti tubing on ceiling to drizzle only downward. Only cold bottled will work.
I bought the Auto Pilot. Check it out online. It only turn on when its needed. Will not exceed 3000 ppm. So that's the magic number there. Much higher could be dangerous.
People say you should use this or that, that why I am writing this thread.
Danger is ever present, too leaky, seal the room. But a good seal will be risky to just using a timer.
So get ya an Autopilot PPM controller. Keeps things even and who knows, you will probably save some money on tank refills.

This is the first I've heard that lower humidity is beneficial when burning co2. What humidity do you try and maintain during the different phases of your grow. How does this tie into those following VPD? I suppose following VPD perameters but keeping humidity in range but on the low end of that range is what I should be aiming for?

Well, first what is that? VPD, I will have to look that up. A calculation? Uptake or discharge from plant?

Holy crap! I may have found a major malfunction!
They sell this pressed bubble sheeting in rolls, for a bit of insulation, but covers quickly and sealed.

THE WORST REFLECTING MATERIAL EVA!!!! Now this is a big deal for you tent growers. Your reflection in those things are hurting you plants, guaranteed.
Now, it's close to the same thing, no no to silver shiny!
Now, I caught mine bouncing off one end. Sides are too far away and bulbs hid behind transformers that way.
See pics below.
Only use ORCA! SO I figure you cut 2 "green sheet boards," (they do not mold) that gives you 4-4'x4' sheets that are perfectly flat. Now with ORCA if leaves brush against that material, it dies instantly.
If you are at 4' now from bulb to plant, it's going to need a raising! Get a lux meter.
Now with 2"x 2" lengths of wood, nail boards to that in each corner, raising "box" up past leaves. Install ORCA on those boards.

This assures an even spread, but also they will jump to attention when you do so!

Check out pics....

I have an autopilot controller and in a 10x7 I go almost 2 grows on a 20lb tank.

Burners propane burners can cause your product to fail testing.

They also if not vented properly and in tip top shape cause a build up of ethylene and major issues with the plants.... I'll stick to my bottled co2. Because I do not vent my room at all

5-10% lower than VPD.

Do NOT use charts they are bullshit and likely to cause you issues..
