Honestly, Turtle is right.. Again..
Run a ventilation setup and not a Co2..If you in a cabinet drill a hole in the bottom about the size of a baseball for passive intake. then dril a hole above the lights and on the side or back .. and opposite the side the bottom hole is on(for air circulation). Attach a 80 cfm fan to the wall (top hole) with a cover and and wire it.
I did the math at Home Depot and it costs about 30 for fan.
I my self just bought a Utility cabinet from Lowes and it for 118.00 bucks.
I is seperated in the middle for 24 inches on both sides. so I set up a mother side and a flower side. and instead of putting 2 fans in for each side. im gunna run Duct through the seperation wall from the mom side to the flower side cool both lamps (keeping the temp down) and ventilating in fresh air from the mother side floor.
really its cheap
50 bucks tops
And i really dont know how much Co2 a small animal would produce..
i mean if you put a lil piggy in a airtight box, ... it would probably die in an hour from Co2 poisoning.
