heard of it but one might think that dry ice might freeze your plants? just a thought.

whats a good smaller setup for co2?

dry ice is hella expensive lol i think it cost me 50-100$ for 5 pounds of it i think it was 10 or 15 bucks a pound cant remember lol it doesnt work as good as co2 tank or generator. and you dont put it on the plants i use to put it in pop bottles around the room with water in them just leave the cap off also remember you have to constantly buy dry ice as its hard to keep it stored it only lasts about a week and by then it produces barely any co2
diy co2 setups work good for small ops like sugar and yeast or dry ice but if your doing a whole room you want to use a generator or a tank and regulator...
co2 is important for plants theres about 300ppms of co2 in the air we breathe which is why our plants grow with out a system... when you increase co2 ppm levels you get anywheres from 30%-100% increased growth it helps them transfer and produce and use sugar in combination with photosynthesis so the lights should be ON when you co2... when the lights are off there is no photosynthesis therefor no point in wasting co2

I've used dryice many times, of course it depends on what you can get it for. Where I am, I pay about $14.00 for a 50lb block, which lasts about 4-5 days.Try Dry Ice Directory - Where to buy Dry Ice for pricing in your area.

lol wow ummm... you need to use your co2 enrichment like this: 3 times a day for 15 minutes at a time. the fans need to be off at this time, and temperature should be about 82 degrees F.

don't use dry ice. too costly... oh, and co2 is used ONLY DURING FLOWERING. it's used to produce 25% bigger buds...

stick with a tank, timer, regulator and some tubing with tiny holes poked in them above your plants so co2 will fall ontop of them.. peace! JD9

I'm using a CO2 w/ regulator. Yes, DON'T use it when your lights are off. If the room is sealed off w/o exhaust fans, then you shouldn't overload the room w/ CO2. Too much is bad (and can be toxic to you buddy). I'm running mine with temps at 74-80F. You can operate them at higher temps which enables your plants to survive w/ the increased temps. I wouldn't worry about buying an air conditioner. Just look at your plants, like the above quote said, your temps at 88-90 are not too bad. If your plants are doing ok, don't worry about it. You are going to spend a lot of money for something you may not need. Peace my brother.

I forgot to mention, the holes in the tubing is ok, but think about it. once the gas falls on the plants It keeps going down. What's more important is to have circulation in the room. CO2 is heavier than air, but with a fan it will spread the gas and continue to circulate it around/through the leaves which is more beneficial then having it cascade down onto the plants then hover on the floor. It's not the base of the plant and dirt that benefits from it, it's the leaves. I use just a tube that's inserted into the back of my fan. My babies are doing great.

my buddies got the controller for co2 where you can play with the ppm or something, all he needs is a tank. btw how much would a controller cost?
