Yeah its a Co2 Tank and I have the timed regulator.

Im still not sure about using this yet.

I was thinking of setting the timer on for 15 or 30 (15x2 4hr interval)minutes during the day then turning it off before lights out for a solid 12hrs off.
DigitalCoast Reviewed by DigitalCoast on . Co2 and bedroom? I just got a co2 system and my grow setup is in my bedroom about 10 feet from where i sleep. My mattress is on the floor and the grow setup is in the closet which the door is open. Is it safe to run co2 right where im sleeping? are there any dangers or things I should worry about? Any tips or advice for this setup? I dont really want to ruin the closet door by cutting room for vents etc I want to either make this work the way my setup is or not use it. Any help would be great.
