Adding CO2 to a grow room. 

Great video! Was wondering about that Vivosun regulator.

Get the air pump off the ground incase of a flood...you could burn the house down in a leak...all electrical items need 2 be at least 2 feet off the ground homie...and have your pump come on and off at 15min intervals so the unit doesn't get hot and pump hot air into your res or pots

Very nice subbed. Can you get more into the specifics of the set up.

How often change your bottle ?

Can you help me with my CO2 setup?

Try 1300 ppm
