co2 is useless above 90+ degrees.. so if your room is getting hot i would worry more about cooling it down before i would worry about co2..

I see, lol. Well my advice is to forget about CO2 and just focus on fine tuning the conditions in your box. Really get it dialed in - that is where you will see your most improvement in yield.

But if you are set on doing something, these are about $100.00: http://www.co2boost.com/

If you search up in https://www.rollitup.org/view.php?pg=faq there are even cheaper homemade yeast contraptions - I have no idea about the efficacy of that stuff though.

check it out man here ya go.

get a water/pop bottle, fill it about half way with warm water, poor enough sugar in it to make the water start to get cloudy, as soon as you can see that its saturated add about 2 teasoons of any kind of yeast you can buy at the grocery store. large yeast is the best. what i did was melt a hole in the top with a lighter. any time you want your plants to have a boost of co2 just shake the bottle and the yeast gives off a reasonable amount of co2. enough to build up pressure as you shake it.
this lasts about a week or untill the yeast has eaten all the sugars or the yeast is just dead.

the sugar and yeast cost more per unit of co2 to produce than purchasing a co2 system..
that being said fuckco2 and get those temps down and give em plenty of fresh air and ventilation

ok buddy that last maybe a week to raise the ppm maybe 300 do some studying and you will see that co2 from a burner or tank even after you add in initial equpment cost is much cheaper..unsubscribed

Air has CO2... so by increasing ventilation you are already solving your problem. CO2 is of course very important for photosynthesis, but making your grow room unbreathable to man isn't going to make buds the size of watermelons.

well of course a co2 setup is going to be more efficient than any other form of co2, but comon its a small closet grow and i bet its on a budget, im just trying to give him the info he needs, not the info that obvious and unaprochable... sry...

and i have heard of it increasing the ppm up to 1200 every time you shake it and the bubbles surface. but thats not a study of mine, just what i heard from the diy...

agreed.

but if your like me and dont have ability to ventelate its not a bad idea, then again small closet grows usualy get suficient air exchange when the closet is open... so just leave it open whenever you can and always have the air inside moving. the plants give off oxygen, so the area around the plants are higher in oxygen than co2, this is why its important to have a fan or two blowing at your plants. also because airborn molds and diseas can settle on leaves and set into your plant, not good.

plants need co2 to grow, carbon is the building block of plant structure... well any organic structure really. without the carbon from the co2 the plant will not have what it needs to grow because the "cement to theyre bricks" isnt there. cement being co2 and bricks being mag. nit. phos. ect... so its kindof important... its really just making sure the plant has almost an overabundance of suply for building.
