Temperature and Co2, dangerous in bedroom?

Hello ya'll

I've just set up my new grow room (I'll put pics up soon), and I bought a co2 system to go along with it.

It came with a full tank, regulator, and control box.

I'm not familiar with the name of the box, but it basically monitors temperature: I set the box to the desired day/night temperatures, and plug in my outlet fans and co2 tank. When the temperature gets above my prefered settings, the outlet fans turn on and eject hot air. At the same time, the co2 switches off so it's not vented out of the room.

Here's a few questions I have:

1) I've heard room temperature goes up when co2 is introduced. What are the ideal day and night temperatures I should set the control box at with co2 in my room?

2) The space is a closet (not airtight) in my room. Should I be worried about co2 poisoning? For precaution I keep my windows cracked, and for now I have the regulator set at the lowest possible setting.

3) I have 4 grand daddy purps and 4 grape punch clones in the closet right now, which were introduced yesterday. Should I even be running co2 yet, or should I wait till they get bigger?

Also, the closet is about 5 ft deep, 6 ft wide, and about 8 ft high, with a 600 watt halide.

Lemme know what you all think!
Thanks!

I'm pretty new to this myself, but I do have one grow under my belt, when I use Co2 I only use it when the lights are on, and in about 10 minutes at a time, 2x a hour in my 5x 5 grow tent(plants don't need co2 during dark time).....I try to keep it around 80-85 when the CO2 is on.....if it's not airtight, some people say co2 is a waste then, I really don't know for sure, but I wouldn't worry about co2 poisioning it takes alot of co2 to poision a person....I personally run CO2 in a veg stage as well, some people say it's a waste, again to each their own

i too have only one grow under my belt, which is why i'm asking these questions haha. yeah i've heard about the veg thing too, but i think it will definitely help the plant grow. i mean, why wouldn't it?

1) During daylight the temp shouldnt go above 85f and at night not go below 60f

2) CO2 is toxic in higher concentrations: 1% (10,000 ppm) will make some people feel drowsy. Concentrations of 7% to 10% cause dizziness, headache, visual and hearing dysfunction, and unconsciousness within a few minutes to an hour. With a cracked window and fans you should be fine but testing the PPM in the room is something you should do.

3) If you can afford the $30 a week or more to fill your tank then sure why not use it in veg. I only use it in the bloom room and rely on good ventilation to provide the co2 in veg room. I just dont think its worth it in the veg room honestly.


A 600w in that area is 3000 lumen per sq ft and that is addiquate coverage.

I think co2 while vegging helps the plants grow but what do I know, I'm a noob.....everytime I grow it's a science experiment, you can do a bunch of shit till you find out something that works for you...

thanks syrius,

but what do you think about using co2 on new clones? should i wait a bit, or let them have it now?

It wont hurt them thats for sure. If you can pay to fill your tank every week then go for it, or if you want to just supliment them for a week or so till they get roots then go for it yeah why the hell not. Just be sure to have the budget for keeping the tank filled for every single day of bloom.
