quick co2 question

Hi!

Is it possible to place a co2 generator or a co2 bottle outside of the grom tent? then hose it in to the grow tent? to avoid it taking up space inside the tent? ive heard of people placing their hose next to a circulation fan so the co2 will spread, does this mean that you can place it outside of the tent?

ALL input is appriciated!

of course you can. i guess it will depend a lot on what type of co2 you are using (generator, yeast can, ect). a generator might be hard to duct in, and since you want to apply co2 when your vent fans are off you may have to add an extra induction system to push the co2 in when your exhaust is off.

I am thinking bottled co2 from a tank because ive heard its safer then a Generator, no DIY yeast can im not so handy. I was thinking of hosing it through the hole where your cables go in the tent. Also im thinking of a timer on the ventilation and a complete co2 system with a monitor and controller. any advice on how to hose it? Thanks Justin

that will work great! bottled CO2 is awesome if you can afford it, it is by far the most expensive in the long run but also the easiest to use and control. and with a tank i can see no reason to ever waste space inside your flowering room to sit it.

i think your plan is spot on, with a monitoring system you can really get some great results from adding co2. for me i just cant justify a set up that expensive for the small space i am working with atm. but if your space is large enough to justify a 300-700$ CAP monitoring system then you will prolly be going thru tanks very fast.

anyways good luck you can never go wrong with co2.

Thanks alot man! i know it sounds overkill but i have a few bucks to spend and im also thinking of the aspect where you can turn your co2 up to 10000ppm to kill bugs etc. thats what sold me!

remember your co2 needs to "fall" over your plants, as co2 is heaver than air it will sink to the ground
a small 4 inch inline fan near the ground level that sucks the air/co2 back up and lets it fall over the plants in a continuous cycle works well
you need to control the environment well to get the best out of it .. all extraction off when the co2 is on,
inject for a set time, let it mix around for a set time then let the extractor turn on again, its best to do this with the co2 controlling units you can buy that will also control your fans and humidity

make sure you can control the heat perfectly before you think of using co2 you will want your temps at around 90f when using co2 its easy for temps to get too high
when turning the extraction off, the plants will feed and drink and grow like crazy if you do it all right .. the co2 injection supports the extra heat which makes them grow like crazy at over 90f

peace

be careful how long you leave it at 10000ppm, i don't know from experience but i have heard it is possible to get it to high for your plants. hard but possible.

IMO CO2 implementation other than intake and outake air exchange is not cost effective and wasted labor. CO2 is primarily focuses on vegetative portion of your grow. Makes vegging plants grow faster. The dilemma is that your stomata open up when lights are on and is effective when temperatures are 80-90 farenheit. So, lets say you are running a carbon filter scubber and you are artifically producing co2. All that Co2 you arelaboriously making is getting sucked out faster than your stomata can utilize it. Another note if you do choose to aritfically make co2 you need a co2 monitor. Too much co2 burns your leaves.

tanks are by far not the easiest to use and control. a generator is many times easier to use and control and is much more consistant.

i tend to agree with you calicat, i do not run co2, i grow NFT hydro, my plants from clones only tend to stay in veg for 2 weeks at the most
as you say co2 is mostly for the veg stage
i find plants grow faster in the early stages with the extra heat without co2
my temps average 85f in the summer months plants do grow faster in this heat with warm nights of 70f during veg and early flower
than in the 75f winter months with colder nights 60f
perhaps co2 will cause a more noticeable improvement for soil growers and those who want to veg for a long time and grow big plants
i really do not think co2 is needed in hydro myself, each to their own those that strive for perfection lol

rediculous. science speaks for its self, but my yield increases back that up completely. co2 is for all stages of plant life and makes dramatic improvements in flower if other enviromental factors are well controlled.

dramatic improvements during flower ... that is ridiculous* LOL
a dramatic improvement would be something like 30-40% more yield, 2-3 weeks less flower time, etc etc using a hps to flower rather than a mh is said to give 30% more yield
this i would consider a dramatic improvement
co2 injection will not make buds mature faster, show me a 10 week strain that grows in 7 weeks with co2
show me a plant without co2 that produces 4oz and the same clone with co2 that produces 6-7 oz, that would be a dramatic improvement in my book
you could get an improvement like this by simply changing strain
plants will grow crazy during veg with co2 because of all the heat too, the heat speeds up veg
but during flower this does not happen so much
for all the extra money you spend on co2 the results are not cost effective but for those looking for perfection at any cost co2 injection is essential
and soil growers looking to keep up with hydro growers

peace

is it the fire, heat, or space that makes the gen easier?

better i would agree, but easier?

I am ofcourse running a Sealed tent i should have added this! But i thought co2 wasnt that important during veg? that they only need low amounts anyway in veg? i was thinking of the co2 for the flowering tent and not the veg tent. Nice to see a little discussion heating up here! im going organic btw and do not plan to keep up with hydro growers but to get the best tasting medicine. Maybe a generator is the way to go.. Thanks to all of you for your input!

a 20+% increase on same strain under very strict and consistant enviromental coditions tell me it works. so does science. i have had over 70 harvests and i have taken the time to properly test different nute, temp, and ,co2 levels over that time. im sorry but your wrong about plants not needing co2 in flower. heat from todays smaller generators is not even noticable, they keep a much more consistant level, and as for easy once they are up and contoller is programmed all i have to do is get propane tank refilled every 3 months.

Any idea on how to hose a generator? Thinking this might be the way to go so i dont have to refill the bottle all of the time and propane is much more used for BBQs etc so not so suspicious

the cost savings of propane vs co2 tanks will pay for the gen and monitor in a year. i have a minigen because my first concern was heat and i wanted to watercool it. i never even used the watercooling part of it. the heat is nothing because flame is so small and run times are minimal.

Ok settled on the Gen then! How about hosing it?

its a tiny box, just put it in room and run hose to propane tank outside of room. it doesnt matter if you pipe it in or not, it will stiil be warm/hot.

Do you think its possible to hang it in the tent? or wallmount it? i really want to keep the floor space to the plants you see. And the minigen is 110v? Im thinking of maybe going minigen now since you mentioned that heat wont be an issue then. Sorry for stupid questions!!
