Adding co2

Hey all welcome..
i have a darkroom 3'11" x 3'11"..my co2 acording to the test is 900..
is this adequate or should i add co2 ???
i am not new to growing just inexperianced with co2 and such.
i can cut my ventilation off for 25 minutes at a time without the temps rising to above 86f..
so if co2 is advised what is the proper way to install... co2 burners are out of the question cause of heat humidity issues..sugaryeast complete wayste due to cost verses efficency..
so what is the most cost effective way to inject co2 with a tank..

also if i inject co2 will i have to increase the amount of nutrients i feed...

Co2 is naturally 900? Is that double regular because you're standing in that small room breathing while making the measurement?

For a (complete) tank setup:

Tank
Regulator
CO2 sensor connected to general controller
Air conditioning (if you have to vent your air all the time, you're throwing money down the drain.I know what you said about temps...but 86 isnt fantastic, if possible cool it other than with ventilation.)

You'll want to attach the tank to the ceiling/sidewall up top, with the tubing coming down to around light level, so the CO2 is dripping onto your kids.

I just have a quick question. Why is the yeast/sugar method too expensive? I have priced out the Co2 equiptment on line and @ shops, and they are hella expensive! I take 20 lbs of sugar and a few bottles of yeast for a grow and with my few grows, have been producing Co2 in the 1300's. I thought that that was fairly decent.

i tried the sugar yeast thing i took 2 2 gal gas tank and the other end pooped it up and a 1/4 inch hose fits in perfect at the sugar and yrast titgten the cap put the tube ina a coup of water and it bubbles away. I stopped doing that though now i use a propane heater single burner. i don't know what ppm it is putting out but sea of grren viudeo 3 has like the same one and he said it works good. what do you think

here is the pic i leave it on 10-15 min. then ventalate to bring fresh air in. what do you think i don't know ppms but i see it is definetly helping them

it really boils down to efficency and economy..
if you are producing ppm of co2 using sugar and yeast you will be one of the first i know..
most yeast sugar solutions only work poorly at best costing much more in the long run than co2 bottled..the basicc co2 injection kit cost 150 ,plus digi timer 15, bottle 99, fill 20..so that is 284 bottle refills are 20 , i bottle does a 8x 8 for 6 weeks of prime co2 optimization at 1500-1800..
so for the cost over 5 years you look at 1164 usd so for a year its
232usd a year wich is 38.67 per grow to add optimal co2 over a 5 year period less as time goes on..
its clean automatic no mess. and way more efficent ..
if you break it down to co2 produced it lookseven better i just couldnt find thaat formula for co2 produced by sugar/yeast..
if the co2 was turned down to 1300 wich is your range as stated it would last longer refilling once less a year so it would be 36.27 usd per grow..
plus with bottled you do not add to greenhouse gas..

just purchased a quitecool 16 inch evaporative cooler,, and dehumidifier..a am holding off on co2 for now just building up to start a sealed grow.. no air in no air out.. just co2 injection at 1800ppm evaporative cooler to keep temps in check, dehumidifier to hold things in place...we will see but it will be ahwhile before i can put into opperation...one step at a time ehh..
jem that looks like the same concept as a co2 burner whatch out for carbon monoxide and temp spikes and it should work fine try running it above your plants for 10 minutes and keeping the vent off for 20 minutes then venting ..
gives plants time to use what you are giving them...

Ive tried the sugar/yeast thing but found it only lasted a few days at a good rate, and it kinda stank. I bought a 20lb tank for 90 and a .2-1.0cfh regulator for 130 or 140 n mine lasted for almost a year. Max level of co2 is 1800ppm. Air has about 300-400 (more in the city). I just refilled my tank today for 22 usd. So for cost not as much as some of the propane generators, plus no heat from it. Dig timer to on/off time synced with exhaust fan and your golden.

blow that co2 on the top of the colas with your circulation fan, shut off all exhaust and let them simmer until the temp gets high...

Your right Where the hell am I- You method does work for min cost. I personally didnt like the smell of the yeast/sugar mix. Plus I had a hard time keeping it going after a few days. I even diy a bottle with a nipple and air hose run into water to see how long it worked. I guess I just like the reliability of a timer synced w/exhaust fan to keep co2 up in the 1500 ppm range. I run an air tube with pinholes through my light hanger holes to mist plants from above. Do you guys run co2 just when flowering or in vegg too? I know it allows for slightly higher temps, not worried now its winter.

I am just going to run 6 weeks into flower..there are debates on weather it lowers potency during flower so i will cut itat 6 weeks or two weeks before harvest..
from what info i have gathered co2 is pretty useless above 87f so keep those temps low..lol

wherethehellami i am not saying your method is bunk,,it works it proven...it has just also been proven that its efficency versus cost puts it above cost of other production procedures in the long run.., and this is my medicine, not for a quick buck or on the cheap,,but top quality meds for life..so i just try to be efficent as possible. i am in it to win it, not to hit it and quit it... lol good day all..

ohh just ordered an optimum air regulator with timer, going to welding supply tommorow to get tank hehehe

Vaporking-Lower potency????? Its used to increase bud size, gerth and potency. Why do you think the dinosaurs were so big? co2 then was "12x's what co2 is today" also if you checked out my link to the co2 calculator it says
"CO2 is an odorless, invisible, and non-flammable gas. It is also safe for humans in the maximum concentrations recommended for plant growth. The average level of CO2 in the atmosphere is about 300 PPM (parts per million). If the level decreases down below 200 PPM in an enclosed growing area, plant growth slows to a halt. Through the years of testing and research, the optimum enrichment level of CO2 for plant growth has been agreed to be about 1500 PPM. With CO2 enrichment, under good conditions, plant growth rates and flowering will increase 20-100%. CO2 can be used from seedling right through harvest." I have done research on this and did try the sugar/yeast method. It just stank smell wise and I found the reg. tank,timer, a more reliable method. Not coming across as a dic, just my opinion.

ohh hey man your not being a dick. shit we all strive for perfection right??
my thoughts are that thc is a protective substance,, for insect repellant and drought protection.. so yes when you add co2 you do increase size and all but if you give that plant the perfect safe secure enviroment wouldnt it produce less of its protective coating??
most of the co2 users i have spoken to stop co2 the last 2 weeks of flowering , decrease the humidity, add extra circulation fans,and one buddy twist the shit out of his plants to add minimal stress, to force the plant to produce more thc.. just a thought...:joint: smoke on my friend thanks for the comments allways welcome..and when critiques of grow styles are given i think the help people to learn.. it is the people who are constntly stabbing at others that get me.. luckily we are all civilized here right..:mrgreen:

I like to think so! I just didnt know if I came across that way. My opinion would be the plant would make more trichs due to increase in bud production. Thc is the result of the plant dying, filling the trichs with resin, coming to its end. So if you increase the size of bud then automaticly have more trichs, in turn more thc. The % of thc would be more strain/nute/grow related. I never heard of twisting them? I have heard not to water to allow the plant to push resin up to the flower/trich.

It is my understanding that potency is determined by genetics and environment plays a factor, only in so much as to maximize the plant's genetic potential by giving it optimum growing conditions.
vaporking, I don't think the plant makes substances in direct response to physical trauma. UVC may help but physically stressing it and creating sub-optimal CO2 levels may decrease it's ability to perform to it's fullest potential.
