cannabis,oxigen, co2
A very slight danger is present from valve damage causing the tank to become an uncontrolled projectile powered by gas escaping at up 1000 pounds per square inch of pressure. Another slight danger (although probably more likely to happen than the previous scenario) is the displacement of air that can happen in the event of quick release of all the CO2 in a tank into a closed area. Both plant and human can perish in this event. Not because CO2 is a poisonous gas, but because the CO2 can displace all the oxygen in the area, causing asphyxiation, or death of the marijuana seeds from lack of oxygen.
