My girl is in a bedroom, I cannot get C02 above 550ppm. What am I doing wrong?
Is the room sealed? Is your space ventilated in any way? Gotta seal it all up otherwise gas dissipates away.
It’s sealed except door cracks
Sealed really means sealed. It needs to be to push high partial-pressures. For example a tent won’t work. Large spaces will require more CO2.
FYI unless you are running double the normal amount of light and pushing nutes at high values; CO2 won’t do a thing for you.
How is the room cooled?
How much did that equipment cost you ?
