Not a problem. The CO2 buckets can work, but even better are CO2 generators or CO2 tanks. With the generator and the tank you would use an atmospheric controller that would monitor the PPM in your room and dose the CO2 accordingly when levels get too low or too high and a good controller will shut off when lights go out. For the tank you will also need a CO2 distributor that has all of the tubing and proper voulbs and you plug this into your controller. It can make a huge difference, up to 30% more yield.
