my room is 8x4x8 = 256 ft^3.
there is about 300 ppm co2 in the air naturally, and I want to reach 1500 ppm so i need to add 1200ppm, to the room to get it to the advised 1500 ppm.
256 ft^3 x .0012 = ~.31 ft^3 i need to add if the co2 has returned to ambient levels.
i have a 20 lb tank and dose twice a day for a half hour at 3cfh. this should add 1.5 ft^3 of co2. . . almost 5 times as much as I need!!!! each dosing. this is dosing almost 6000 ppm into my room, sounds like a lot, but some of it escapes at a constant rate, I have my air pump for res outside of the tent to get good o2 air in the res to keep DO up. this is probably creating a positive pressure inside the tent and displacing a decent amount of air/hr.
I wish i had a monitor, even if it made my tank go faster, i would know that my ppm is where i want it a all times. I will get a controller when i can afford it.
anyways my 20 lb tank has been dosing for about a month now, and still has a long way to go before i need to refill it. 3 weeks sounds like way too much dosing to me. . . but if you are losing the concentrations due to air exchange, then it could go fast! make sure the room you are dosing is sealed if you want to dose less. . . the point of dosing co2 is to have a sealed environment to keep the ppm high.
if you have a controller though, i would believe that it's keeping it exactly right. the way that they measure the co2 in the air is very accurate. (that's why they are hundreds of dollars.)

its probably easier for someone like CMX to shake off a bad comment or a hater because he is good at what he does, and he knows it. It would probably be different if he was just starting out and learning, and really wasn't doing a good job. it would be a lot harder to take that criticism if he believed it was true!
i am a man of faith, in that I have faith in myself. and on top of that, I grow for myself. so, i only need to please one person. ME! I have struggled every step of the way to learn how to cultivate a living, breathing, reactive, dynamic plant like we all do. some people are just good at it without much effort (my friend FB is like that, i tought him everything he knows, and he was better than me on his second grow! lol. but i still have more overall knowledge, if he reads this post. biotch!) thats not me, i have to give it everything I got.
My friends all appreciate the fact that i have top shelf bud to share with them, instead of the mexi-crap we can get readily in my area. They encourage me, and stick up for my weed, because it is in fact very good, and because i have good friends.
if you weed isn't great, at least it was cheap, and keep it up and you will get better. The bottom line is, if you do it for yourself, it wont matter what other people say. just believe in yourself and youll be happy all your life.
let the haters hate, and if they diss your shit, don't give them anymore. tell them they can smoke the local shit that smells like their mama's snatch. it's your shit. you have the power! plus when you get better, the'll never know, and they can go on in ignorant bliss, and so can you!
well, just my 2 cents anyways. the 2 cents from a man who only has like 4 cents.
MAX, i'll read that when i can concentrate better. lol. to much for my brain right now.
CMX, LOOKING GOOD STILL. hurry up and grow some monsters already damnit. lol.
WOF! ( i can't wait till you have some bomb pics for us cmx!)
lol
