Indoor Diy co2 questions

[PoopsMcDoogle]

I am trying to figure out how much one of these DIY generators will produce hourly. I have 84 cu.ft. of grow space. So 84 x 0.0013(1300PPM) is 0.11 cu.ft. of CO2 every 4 hours I need.(I'm guessing) 1 pound of sugar makes a half pound of CO2. 1 pound of CO2 makes 8.7 cu.ft. of CO2. But at what rate are you getting the 8.7 cu.ft.? Is that per hour, 4 hours, per day, or the total amount 2 pounds of sugar will produce over its lifetime?? Another thing I was reading last night was about the temperature, humidity, and ppm having to be balanced. What is a good method of determining where to have these numbers at? The example given for optimum growing conditions was 90-95F degrees, 1300ppm, and like 40 percent humidity. Why such high temp.? Thought that was a no-no? Then why worry about heat issues when you can just up the CO2? Nobody ever mentions that for a solution for heat problems.(Like I had ALL LAST GROW!) What a cheap and easy fix until you can properly fix it. If 90-95 degrees is what I'm shooting for then should I add my other 400hps for a total of 800hps.(In cooltubes, 8in. Inline fan)? I appreciate any help.

Imo i think its a waist of time with your extraction running!

Itks not a waste of time because there is no extraction from the room itself. The fresh intake goes through the cooltube and through the outtake into another room. There are three rooms involved in the grow. Fresh air from living room through closet (grow room) dumped into spare bedroom. I also have another fresh air intake into the grow room(closet).The only outtake for the closet itself is a 4in. Inline fan for odor control only! I also need to figure out how often to run it so I don't extract my CO2. Ya dig?

What I'm trying to say is the heat doesn't enter the room. The only thing being extracted is through the light with the 8in. Fan (cooltube) before it can enter the room. The air in the room is not extracted at all until they start smelling which I will use the 4 in. Fan at specific times for this.

will you not still get alot of radiant heat from the light as it builds up? or is this because higher temps are ok with co2 etc? i have a cooltube and though not much it puts out some heat.
you could get a fan speed controller and run it low with a bit more co2 to offset the loss maybe.
no idea though just guessing

My temps stay at 77 degrees. I got a very powerful 745 cu.ft. Mtn Gearsmith inline fan(with speed control) that sucks it all out before it has a chance to buildup. There is no air being taken from the growroom. NO OUTTAKE. Just the light has extraction. So how are you people getting that I am losing CO2?? And as for the question "is it because higher temps are okay with CO2 etc.?" I don't know because that is the reason I started this thread if you read my first post there friend.

I am about to quit these god damn forums. Got this posted on 4 other websites and not a damn! WHAT GIVES??9vhndbkdTwqjmdvansDsbhbhGjhWerthjgfdwhjgfdhjhgfdsdfghvcxdfghjgfddhgfdfjgfdfgghj! Where's all the smart fucks at?!!!

I think you might want to find yourself another website, its not that kind of website where you can come on here and make demanding posts. Go smoke one and relax

Hey man. Patience. I have read your whole thread here, but I just don't have much advice. It takes time for the guys in the know to catch stuff sometimes. Keep it cool. I suggest searching around here for the info, I have read and learned a lot just from browsing around with that search bar up top. You've seen me around, you know I'm a helper here, but it's not instant-gratification. Actual help here isn't always a scratch off ticket at the seven-eleven.

If you have an extraction fan inside your tent, it pulls air out, that includes, heat and co2. So there is no way to have an exhaust fan 'just for odor'. It pulls air out either way, whether it smells or not. So yes, it will be pulling your co2 out. How much I can't say. I have seen the co2 bags and home-made stuff. I think they at least have a 15 minute interval that all fans are off including exhaust so that the co2 can get to the plants before being blown around or sucked out.

Growbewan uses diy co2. He has gone to bed for the night, but I bet he can help out. Co2 isn't a simple thing to deal with and regulate correctly, hence why we don't tell people that to fix their heat problems, that would be kinda ridiculous. See what I mean. Again, I know you have seen me around, I'm a nice dude and all to help someone, but you gotta be patient please, sir. I promise it's for the best.

There are very few people, who use CO2, due to the cost, and the automation that it requires, to be of use. DIY CO2, is pretty much wasted energy, as it takes a bunch of fermentation to make enough CO2, to really be useful, and you need a lot of CO2, to be able to run at the higher temps. The amount of sugar, and yeast needed, the costs are much higher than bottled CO2. While your startup costs, for using bottled CO2, are high, they are much lower than the sugar and yeast costs, for even a single full grow, on the size room you are planning.

P.S. You really need to watch your attitude. The Mods, have very low tolerance for jerkwads. That is probably why we don't have a bunch of flame wars, on this forum. That among others, is the main reason, that this is the friendliest forum on the net.
